Based on outcrop, core, and thin-section observations, combined with cathodoluminescence, scanning electron microscopy, and geochemical analyses, we systematically investigate the dolomite types, petrophysical properties, and pore systems of the reservoirs. Furthermore, the genetic mechanisms of dolomite reservoirs in the study area are discussed. The results indicate that dolomite is widely developed in the study area, primarily consisting of grain dolomite and crystalline dolomite. The main reservoir lithologies include grain dolomite, fine-crystalline dolomite, and silt-crystalline dolomite, with medium-crystalline dolomite being the least abundant. The reservoir space comprise intercrystalline pores, intergranular dissolution pores, oversized dissolution pores, intragranular pores, intragranular dissolution pores, and moldic pores. C-O isotopes exhibit positive δ¹³C and negative δ¹⁸O values, with Z-values around 130, confirming a saline marine origin. Major and trace elements reflect variations in seawater salinity and dolomitization intensity. High FeO and MnO contents, along with cathodoluminescence characteristics, indicate a reducing environment during early diagenesis. Rare earth element patterns show overall low concentrations with positive Ce anomalies, further supporting a predominantly reducing environment, though redox conditions vary slightly among different lithologies. Oolitic shoals and grainstone shoals constitute the material foundation for reservoir development, while dolomitization and dissolution are key factors in reservoir formation. The reservoir quality is jointly controlled by sedimentary environment, dolomitization, and dissolution processes. This study enhances the understanding of the genetic mechanisms of dolomite reservoirs in the Third Member of the Feixianguan Formation in the Puguang Gas Field, providing theoretical support for future exploration and development.

Introduction Global carbonate reservoirs account for 38% of the world's total proven hydrocarbon reserves, with marine carbonate rocks contributing up to 60% of large oil and gas fields. Among these, dolomite reservoirs represent a critical exploration target worldwide (Yang Y et al. 2024; Zhang Dw 2021;Janjuhah HT et al. 2021). The Third Member of the Feixianguan Formation (hereafter referred to as Fei-3 Member) in the Puguang Gas Field is a typical marine carbonate reservoir. Although four industrial gas wells have been drilled (accounting for 7% of Puguang's total reserves), its recovery rate remains as low as 9.15%, leaving substantial untapped resources with significant exploration potential. However, its unique geological setting and complex diagenetic evolution pose key scientific challenges for reserve evaluation and exploitation. The T 1 f 3 was deposited in an Early Triassic restricted platform environment, with burial depths generally exceeding 4,500 m (locally > 6,000 m), overburden pressures > 150 MPa, and formation temperatures of 120–220°C—conditions that profoundly influence diagenesis and fluid activities. Multiphase tectonic uplift/subsidence has subjected the reservoir to epigenetic dissolution, deep overpressure, and thermochemical sulfate reduction (TSR), resulting in a complex multi-genetic pore system (Liu X et al. 2022;Wen W et al. 2023 ). Some scholars proposed that high-quality reservoirs result from synergistic effects of favorable sedimentary facies, epigenetic dissolution, deep overpressure, and TSR-induced dissolution, with TSR and hydrocarbon overpressure being critical for porosity enhancement(Ma YS et al. 2007 ). In contrast, Some researchers emphasized the dominance of penecontemporaneous reflux dolomitization, suggesting that evaporative reef-shoal facies are more conducive to reservoir development (Jiang XQ et al. 2014). Several studies highlighted the decisive role of eogenetic dissolution in porosity formation (Yang WQ et al. 2023 ). Nevertheless, despite extensive research on T1f3 dolomite reservoirs, key controversies persist: (1) The coupling mechanism between sedimentation and diagenesis remains unclear due to insufficient systematic studies; (2) Quantitative characterization of dolomitization processes is lacking, with unresolved contributions of different mechanisms (e.g., evaporation-pumping, reflux infiltration, burial dolomitization) to reservoir quality; (3) The stages of dissolution and their controls on porosity evolution remain debated. These knowledge gaps severely constrain further exploration. To address these challenges, this study integrates core/thin-section observations, cathodoluminescence (CL), and C-O isotope analyses to systematically investigate the genetic mechanisms of dolomite reservoirs, providing theoretical foundations for optimized hydrocarbon exploration in the Puguang Gas Field. 2. Research Background The Puguang Gas Field, located in the northeastern Sichuan Basin, is situated at the northern margin tectonic belt of the Yangtze Craton, adjacent to the Qinling Orogenic Belt (Fig. 1 a). Within the Sichuan Basin, the lithology of the Lower Triassic Feixianguan Formation exhibits a gradual eastward decrease in terrigenous clastic material and a corresponding increase in pure carbonate deposits. Based on this characteristic, the region can be broadly divided into three zones: the western clastic rock zone, the central transitional lithology zone, and the eastern carbonate rock zone. The Feixianguan Formation maintains conformable contact relationships with both its overlying and underlying strata.By the late Feixianguan depositional stage, continuous sea-level fall transformed the northeastern Sichuan Basin into a stable platform environment, yielding alternating purple-red, gray-purple, and yellow-gray argillaceous–micritic carbonates of variable thickness. Lithologies include argillaceous dolomite, micritic dolomite, mudstone, argillaceous limestone, and micritic limestone, reflecting a marine-to-terrestrial transitional setting (Zhang JZ et al.2011). The Fei-3 Member (111.4–149 m thick) predominantly comprises restricted platform facies, with gray micritic dolomite, micritic limestone, and mixed carbonate rocks interbedded with grain-supported deposits (e.g., grainstone dolomite, oolitic limestone, and oolitic dolomite) and local mudstone/dolomite interlayers. Four microfacies are identified: grain shoals, bioclastic-algal mats (microbialites), oolitic shoals, and lime flats, collectively representing a transgressive systems tract (L PW et al.2013). The sedimentary profile (Fig. 1 b) indicates a transition to a gently sloping epeiric sea-like platform during Fei-3 deposition, with intra-platform shoals and microbial mats developed on paleo-highs, while lime flats and dolomite flats dominated lows. 3.

First, the 200-mesh powdered samples were dried in an oven at 105°C for 3–4 hours, then immediately transferred to a desiccator and cooled for 8 hours before weighing. Approximately 1.5 g of each sample was accurately weighed into a crucible that had been cleaned with alcohol and air-dried. The crucibles were placed in a muffle furnace at 920°C and ignited for 3 hours, with no more than 35 samples heated simultaneously. After ignition, the crucibles were transferred while still hot into a desiccator and cooled to room temperature for 3 hours before weighing. Weighing was conducted within 2 hours in a constant-temperature environment maintained at 25°C. The LOI was calculated based on the mass difference between the crucible with sample and the empty crucible (assuming constant crucible mass). A 0.6 g aliquot of the pre-ignited sample was mixed uniformly with anhydrous lithium tetraborate flux (Li₂B₄O₇) at a ratio of 1:8. The mixture was placed in a platinum crucible, followed by the addition of one drop of a mixed flux consisting of 1% LiBr and 0.5% NH₄I. Fusion was carried out at 1250°C using an Analymate-V8C four-head high-frequency fusion machine to produce glass beads. If cracks or opacity were observed in the glass beads, the fusion process was repeated. The glass beads were analyzed using a Rigaku RIX 100e X-ray fluorescence spectrometer (XRF). The concentrations of major elements were calculated based on a bivariate fitted working curve established using 36 silicate reference materials. Corrections were applied using the Traill-Lachance empirical algorithm, and the analytical precision was generally better than 2%–5%. The results are presented in Table 2 .

Approximately 40 mg of dried 200-mesh powder samples and reference standards were accurately weighed and placed in pre-cleaned Teflon bombs.A mixture of purified 1:1 HNO₃, HF, and HClO₄ was added sequentially. The samples were subjected to ultrasonic oscillation for 1 hour to ensure homogeneous mixing and then placed on a hotplate and evaporated to dryness after 3 days of constant-temperature heating.Subsequently, purified 1:1 HNO₃ and HF were added again to the dried samples, with care taken to avoid sample loss. The bombs were sealed and placed in an oven at 190°C for 48 hours. After heating, the oven door was opened and allowed to cool for 1 hour before removal.A volume of 4 mL of 4N HNO₃ was added to each sample, followed by 30 minutes of ultrasonication. The samples were then returned to the oven and heated at 170°C for 4 hours. After heating, the samples were promptly diluted 2000-fold and spiked with an Rh internal standard solution (1:1) to correct for instrumental drift.Reference materials included USGS standards W-2, G-2, BHVO-1, and Chinese national rock standards GSR-1, GSR-2, and GSR-3, along with a procedural blank.

The standard deviations for δ¹³C PDB and δ¹⁸O PDB were 0.05‰ and 0.07‰, respectively. To evaluate whether the isotopic compositions of the samples had been altered by post-depositional processes, the samples were treated with a mixture of HF + HNO₃ for decomposition. Major element contents were determined by external standard calibration using inductively coupled plasma atomic emission spectrometry (ICP-AES), while trace element contents were measured via inductively coupled plasma mass spectrometry (ICP-MS) employing Rh as an internal standard.Each sample was analyzed six times, and calibration was performed using international reference materials (e.g., GSR-1, JSD-1), replicate samples, and blank samples. Analytical accuracy and precision were monitored through control samples and repeated measurements, with errors consistently below 2%. The results are presented in subsequent sections. 4. Results 4.1 Reservoir Basic Characteristics Through systematic compilation and in-depth statistical analysis of core data from Well Puguang 2, Well Puguang 6, and Well Puguang 10 in the Puguang Gas Field, as well as comprehensive and detailed petrographic thin-section analysis, the study classified and characterized the reservoir rocks based on petrographic observations. The results indicate that the Fei-3 Member reservoir rocks are predominantly composed of dolomite, with a minor amount of limestone.The dolomites in the Fei-3 Member can be classified into the following structural types: oolitic dolomite, residual oolitic dolomite, medium-crystalline dolomite, fine-crystalline dolomite, and silt-crystalline dolomite. 4.1.1 Grain Dolomite Grain dolomites mainly include grainstone dolomite, oolitic dolomite, and residual oolitic dolomite. Microscopic observations (Fig. 2 a) reveal that grainstone dolomite exhibits a micritic or fine-crystalline texture, with a high grain content (generally exceeding 50%). The grain size typically ranges from 0.05 to 0.5 mm, displaying moderate to good sorting and subrounded to rounded grain shapes. The interstitial material between grains consists mainly of euhedral to subhedral sparry dolomite, forming an intergranular pore-filling texture. Oolitic dolomite appears dark gray to brownish-gray (Fig. 2 b), with ooids as the primary framework (60–80% content). The ooids measure 2–3 mm in diameter, showing poor sorting but good rounding. The ooid interiors are replaced by dolomite, while the intergranular spaces are cemented by micritic to silt-crystalline and sparry dolomite. The rock retains its original structure, with microscopic observations revealing typical concentric ooid layers. Additionally, the first-stage marine cement, characterized by an isopachous rim structure, is identified within intergranular pores. This suggests that the rock formed through early dolomitization of oolitic limestone. Residual oolitic dolomite is primarily composed of dolomitized residual ooids and algal grains (content exceeding 60%), with observable residual ooid textures or ghost structures (Fig. 2 c, d). It is inferred that this rock type originated from intense dolomitization and recrystallization of oolitic limestone, influenced by meteoric freshwater dissolution, resulting in common intragranular dissolution pores. 4.1.2 Crystalline Dolomite Based on crystal size variations, this rock type can be classified into medium-crystalline, fine-crystalline, silt-crystalline, micritic dolomite, and various transitional lithologies. Among these, silt-crystalline and fine-crystalline dolomites are the most widely distributed, forming the predominant components of this category.Medium-crystalline dolomite exhibits a light gray to brownish-gray appearance and is primarily composed of medium-grained dolomite crystals (Fig. 2 ). Microscopic observations reveal that the crystals are predominantly subhedral in shape, displaying a mosaic texture, with occasional dusty rims or ghost structures of original grains.The fine-crystalline dolomite lithofacies predominantly exhibits brownish-gray, light gray, and yellowish-gray hues. Mineralogically, it is primarily composed of fine-crystalline dolomite with grain sizes ranging from 0.1 to 0.25 mm (Fig. 2 ). Microscopic observations reveal that the crystals are predominantly euhedral to subhedral in form, with local development of anhedral crystals. Distinctive "dusty rim" textures and grain ghost structures are commonly observed. The rock often contains calcareous or argillaceous inclusions. Comprehensive studies indicate that this lithofacies formed through intense dolomitization of precursor grainstones, with the original sedimentary structures nearly completely obliterated. The silt-crystalline dolomite lithofacies is characterized by light gray to yellowish-gray coloration, with mineral composition dominated by silt-grade dolomite crystals (0.05–0.1 mm in size). Microscopic examination shows that the crystals are mainly subhedral to anhedral in shape, frequently containing calcareous or argillaceous inclusions, and occasionally displaying black filamentous algal laminations (Fig. 2 e). Integrated research suggests that this lithofacies originated from penecontemporaneous dolomitization of low-energy lime mud deposits. The rock exhibits high compactness with weak dissolution features. The pore system is predominantly composed of intercrystalline pores, locally containing minor dissolution vugs. Porosity parameters range between 2% and 5%, indicating moderate reservoir qualityres, often lined with bitumen. Consequently, dissolution plays a significant role in the formation of these reservoir spaces. 4.2 Reservoir Space Types 4.2.1 Intercontinental Pores, Intercrystalline (Grain) DissolutionPores, and Oversized Dissolution Pores Intercrystalline pores are formed by the recrystallization of dolomite crystals of varying sizes, which are randomly arranged within the rock. These pores represent the primary reservoir space in the study area, accounting for 52% of the total porosity. They are widely developed in various crystalline dolomites, including silt-crystalline, fine-crystalline, medium-crystalline, and coarse-crystalline types.Intercrystalline (grain) dissolution pores result from the enlargement of intercrystalline pores due to dissolution and are highly prevalent. They occur in all types of crystalline dolomites, residual oolitic dolomites, and arenaceous dolomites (Lv LS 2022 ).Intragranular dissolution pores, along with oversized dissolution pores, constitute 30% of the total porosity and represent one of the critical reservoir spaces in the Fei-3 Member. These pores are commonly observed in oolitic dolomites and arenaceous dolomites, primarily formed by the dissolution and enlargement of intergranular cements or matrix. Their development is closely associated with the dissolution of cements or matrix in grain-supported structures, making them typical secondary porosity types.In the Fei-3 Member of the study area, fine- to medium-crystalline dolomites exhibit the most developed intercrystalline (grain) porosity. Microscopic observations (Fig. 3 ) reveal that these pores are predominantly intercrystalline pores and intercrystalline dissolution pores, with minor oversized dissolution pores. 4.2.2 Intragranular pores, intragranular dissolution pores, and moldic pores In the Fei-3 Member of the study area, intragranular (intracrystalline) pores are mainly composed of intragranular pores, intragranular dissolution pores, and moldic pores, accounting for 17% of the total dissolution pores. Intragranular pores are formed by grain cleavage or fracturing. Intragranular dissolution pores are created through partial dissolution of grains. Moldic pores result from complete dissolution of grains while preserving their original morphology. These intragranular (intracrystalline) pores primarily develop in silt-fine crystalline dolomite and muddy-silt crystalline dolomite. A small amount of intragranular pores are developed within bioclasts, which appear as floating grains in a muddy-silt crystalline matrix. The pores include intragranular pores, intragranular dissolution pores, and moldic pores, with pore diameters ranging from 1 to 15 mm. A minority of the pores are filled with bitumen ( Fig. 3 e、f、g、h). 4.3 Reservoir Physical Property Characteristics The reservoir properties in the Puguang area are generally favorable but exhibit significant variability and strong heterogeneity. Analysis of dolomite reservoir samples from the Fei-3 Member in five wells indicates a clear correlation between porosity and permeability (Fig. 4 ). Overall, porosity shows a positive correlation with permeability, though the relationship is complex, reflecting the diversity of reservoir space types. The porosity of limestone, dolomitic limestone, and calcareous dolomite is mostly below 2%, with average values of 1%, 1.6%, and 1.922% respectively. Their average permeability values are 0.594×10 − 3 µm 2 , 0.119×10 − 3 µm 2 , and 0.133×10 − 3 µm 2 respectively. In contrast, microcrystalline-silty dolomite, fine crystalline dolomite, and fine-medium crystalline dolomite show average porosity values of 2.08%, 3.33%, and 4.92% respectively, with corresponding average permeability values of 0.244×10 − 3 µm 2 , 0.905×10 − 3 µm 2 , and 1.64×10 − 3 µm 2 . These data demonstrate that the reservoir properties of the Fei-3 Member are influenced not only by lithology but also by rock grain size. Dolomites exhibit better porosity and permeability than limestones, and coarser crystalline dolomites show superior pore characteristics. 4.4 Geochemical Characteristics 4.4.1 Carbon and Oxygen Isotope Features The carbon and oxygen isotope analysis results from Wells Puguang 2, Puguang 6 and Puguang 10 demonstrate that the dolomite rocks in the Feixianguan Formation's third member exhibit:δ 13 C values are consistently positive, ranging from 2.31% to 3.24% PDB with limited variation;δ 18 O values are uniformly negative, varying between − 4.82% to -6.75% PDB. The dolomites display characteristically negative δ 18 O values and positive δ 13 C values ,and the results are shown in Fig. 5 . The carbon-oxygen isotope distribution pattern shows that samples plot to the right of normal marine values and above the meteoric water line, with oxygen isotope compositions more depleted than typical seawater. Sedimentary facies analysis indicates the third member primarily developed intra-platform shoals, microbial mounds, dolomitic flats and lime mud flats. During diagenesis, these carbonates experienced sea-level fluctuations, with the negative δ 18 O signatures directly related to prolonged meteoric water leaching. Geochemical evidence suggests the enriched δ 13 C values show temporal-spatial correlation with natural gas accumulation in the reservoir. The continuous metasomatism by CO2 components with high δ 13 C values in diagenetic fluids ultimately led to the positive carbon isotope composition of the dolomites. 4.4.2 Major and Trace Element Characteristics The distribution of trace elements is mainly controlled by sedimentary and diagenetic environments, reflecting characteristics of sedimentary environment and fluids (LI X. et al 2024 ;ZHENG RC. et al 2009 ). Analysis results of Fei-3 Member samples show:The bioclastic micritic dolomite sample PG2-4 has the highest Na2O content;The bioclastic silt-crystalline dolomite PG6-1 has the lowest Na2O content;The residual oolitic silt-fine crystalline dolomite PG2-13 has the highest Sr content (449.10×10 − 6 );The bioclastic micritic-silt crystalline dolomite PG6-4 has the lowest Sr content (111.60×10 − 6 );The residual oolitic silt-fine crystalline dolomite PG2-13 has the highest CaO content (38.05%);The arenaceous sparry dolomite PG10-4 has the lowest CaO content (30.95%);The residual oolitic silt-fine crystalline dolomite PG10-3 has the highest MgO content (20.47%);The residual oolitic silt-fine crystalline dolomite PG2-13 has the lowest MgO content (20.47%). As shown in the bar chart of Sr, Na contents and Na/Sr ratios of Fei-3 Member dolomite samples (Fig. 6 a), the bioclastic micritic dolomite has the highest Na content and lowest Sr content, with the highest Na/Sr ratio (> 2). Next are arenaceous sparry dolomite and bioclastic silt-crystalline dolomite with Na/Sr ratios > 1.1. Finally, residual oolitic fine-crystalline dolomite and silt-crystalline dolomite have Na/Sr ratios arenaceous sparry dolomite > bioclastic silt-crystalline dolomite > residual oolitic fine-crystalline dolomite > silt-crystalline dolomite. As shown in the Mg/Ca ratio distribution bar chart of Fei-3 Member dolomite (Fig. 6 b), arenaceous sparry dolomite has the highest Mg/Ca ratio, ranking first. Next are silt-crystalline dolomite, bioclastic micritic dolomite and residual oolitic fine-crystalline dolomite in the second tier. The lowest is bioclastic silt-crystalline dolomite. Mg/Ca ratio represents the completeness of dolomitization, indicating inconsistent degrees of dolomitization in Fei-3 Member samples, ranked from high to low as: arenaceous sparry dolomite > silt-crystalline dolomite > bioclastic micritic dolomite > residual oolitic fine-crystalline dolomite > bioclastic silt-crystalline dolomite. 4.4.3 Characteristics of FeO and MnO with Cathodoluminescence Previous studies indicate that calcite precipitated from seawater has equilibrium concentrations of FeO and MnO at 2.5×10 − 6 ~50×10 − 6 and 1.3×10 − 6 , respectively, while dolomite exhibits similar FeO and MnO contents of 3.8×10 − 6 ~64×10 − 6 and 1.3×10 − 6 (LI X 2021).The higher FeO and MnO contents in dolomite are typically interpreted as resulting from formation in reducing environments with Fe- and Mn-rich fluids or preferential incorporation of Fe and Mn into the dolomite lattice during later diagenesis(Veizer J. et al 1983;Al-Aasm IS. et al 2002 ;Rezaie P 2016 ). The Fei-3 Member dolomites in the study area exhibit the highest FeO and MnO contents, with FeO ranging from 2480×10 − 6 to 6310×10 − 6 and MnO varying between 31×10 − 6 and 99×10 − 6 , significantly higher than those of typical marine-precipitated dolomites. Different lithologies of dolomite also show slight variations in Mn content (Fig. 6 c). Bioclastic micritic dolomite and arenaceous sparry dolomite have the highest Mn contents, followed by residual oolitic dolomite, while silt-crystalline dolomite and bioclastic silt-crystalline dolomite have the lowest Mn contents. As shown in Fig. 7 , the Fei-3 Member dolomites display dark yellow to dark brown cathodoluminescence (CL) with low-intensity luminescence. Microscopic observations reveal patchy luminescence in some samples, with most dolomite crystals exhibiting a zoned luminescence pattern characterized by bright cores and dimmer edges. This luminescence behavior correlates with the diagenetic "dusty core, clear rim" texture. Combined with the widespread occurrence of relict textures in the Fei-3 Member dolomites, these features suggest that dolomitization primarily occurred during the early diagenetic stage in a reducing environment. 4.4.4 Rare Earth Element (REE) Characteristics The enrichment-depletion patterns of europium (Eu) are controlled by migration and accumulation processes of calcium-bearing rock-forming minerals, while cerium (Ce) isotope composition sensitively indicates redox conditions in surface environments - showing negative Ce anomalies under oxidizing conditions and positive Ce anomalies in oxygen-deficient environments. Penecontemporaneous and seepage-reflux dolomitization formed in supratidal evaporative dolomitic flat environments exhibits significant Ce depletion (δCe 1.2), which are closely related to hypersalinity caused by supratidal evaporation (increased Mg² + /Ca² + ratio). In contrast, mixing-zone dolomitization occurs in the marine-freshwater phreatic transition zone, with δCe values approaching 1 (1.02 ± 0.05) and reduced Eu anomaly amplitude (δEu ≈ 0.85). This formation mechanism may involve salinity reduction (decreased Mg²⁺/Ca²⁺ ratio) caused by freshwater influx and preferential Ca²⁺ precipitation. Burial dolomitization forms in relatively closed diagenetic systems, showing relative Ce enrichment (δCe > 1.1). Notably, in oxidative diagenetic environments, total REE content increases by 15–20% on average compared to reducing environments. Analysis of REE in the Fei-3 Member shows generally low total REE content. The REE pattern diagram,as shown in the Fig. 8 , reveals certain positive Ce anomalies. Combined with low total REE content and cathodoluminescence characteristics, this suggests formation in a reducing environment during early diagenesis, related to low-energy water conditions and restricted fluid circulation during deposition. Different lithologies show slight variations in REE characteristics:Micritic dolomite shows the widest range of positive Ce anomalies,Silt-crystalline dolomite follows. Residual oolitic dolomite shows nearly identical values with no significant variation: The histogram of total REE content shows:Bioclastic micritic dolomite has the highest total REE content,Bioclastic silt-crystalline dolomite ranks second,Other rock types have lower total REE content.These characteristics indicate that the Fei-3 Member environment was predominantly reducing, but with slight redox variations: Microbial micritic/silt-crystalline dolomite shows wider positive Ce anomaly ranges and higher total REE content, possibly related to shallow water and strong photosynthesis creating localized oxidative microenvironments in bioclastic algal shoals (microbial mats) Residual oolitic dolomite, deposited under high hydrodynamic energy with good fluid circulation, remained entirely in a reducing environment This difference reflects how various microfacies' water energy levels and biological activities regulate sediment-diagenesis geochemical signals. 5. Genetic Mechanism Analysis of Dolomite Reservoirs 5.1 Oolitic Shoals and Arenaceous Shoals as Fundamental Material Basis for Reservoir Development Sedimentary microfacies serve as the dominant controlling factor for reservoir development, with their mechanisms manifested in two dimensions: lithofacies associations and diagenetic evolution. At the macroscopic scale: The spatial distribution characteristics of reservoir spaces are controlled by lithofacies association patterns of sedimentary microfacies, reflecting relatively homogeneous diagenetic environmental features during specific geological periods. At the microscopic level: This is manifested through selective precipitation of mineral components and directional control over in-situ development of pore networks. The best reservoir intervals develop in oolitic shoals and arenaceous shoals, where primary intergranular pores and exposure-related dissolution pores form the foundation for reservoir development. Although bioclastic algal shoals (microbial mats) microfacies have fewer primary pores, they form silt-crystalline dolomite with high intercrystalline porosity through early dolomitization and penecontemporaneous dissolution, exhibiting reservoir properties second only to grain shoals. The reservoir differences between these two microfacies reflect the coupling effect between sedimentary environment and diagenesis. Their exposure above sea level not only facilitates primary pore development but also makes them relatively weak stratigraphic zones and topographic highs, favoring constructive diagenetic modifications such as dissolution and dolomitization that create various reservoir spaces. Other microfacies like bioclastic algal shoals (microbial mats) and lime mud flats exhibit poorer reservoir conditions,and the results are shown in Fig. 9 . 5.2 Dolomitization and Dissolution are Key to Reservoir Formation 5.2.1 Dolomitization The genetic mechanisms of dolomite in the Feixianguan Formation have multiple academic interpretations, with three dominant models: evaporation pumping, seepage reflux, and mixed-water dolomitization. Some scholars, through petrographic studies, suggest that the formation of crystalline dolomite should be attributed to burial dolomitization. In the study area, the Z-values of the Fei-3 Member are all around 130, indicating saline seawater and belonging to the high-salinity dolomitization model. This model mainly includes the evaporation pumping and reflux infiltration modes, emphasizing the importance of evaporation in dolomitization. The evaporation pumping dolomitization manifests as a penecontemporaneous alteration process of supratidal surface sediments in tropical environments, with its mechanism consisting of three key stages: first, continuous evaporation of interstitial water leads to salinity enrichment (negative δ¹⁸O values), promoting gypsum precipitation to form high-magnesium brine (Mg/Ca > 8); second, the high-magnesium fluid migrates inversely through capillary action, triggering the dolomite conversion reaction of aragonite particles; finally, characteristic gypsum nodules form at the petrographic level, and this mineral assemblage constitutes the hallmark product of evaporation pumping. In contrast, the reflux infiltration mode is characterized by the gravity-driven downward migration of high-density brine into deeper sedimentary layers, primarily acting on early diagenetic carbonate bodies to form metasomatic dolomite through replacement reactions. The spatiotemporal differences between the two processes are as follows: evaporation pumping is strictly controlled by the supratidal surface environment (burial depth < 3m) and belongs to penecontemporaneous diagenetic events; reflux infiltration continues into the middle-late diagenetic stages and is commonly found at sequence boundaries in paleotopographic depressions. Microscopic examination of the Fei-3 Member dolomite revealed no gypsum minerals, with dolomite commonly displaying a "dusty core and bright rim" structure. Cathodoluminescence analysis shows low-intensity luminescence, appearing dark yellow to dark brown overall, with patchy luminescence observed in some areas. Microscopic observation indicates that most dolomite crystals exhibit a zonal luminescence pattern with high brightness at the center and low brightness at the edges, and this luminescence characteristic is correlated with the diagenesis of the "dusty core and bright rim" structure. The δ¹³C values of dolomite in the study area are positive, while δ¹⁸O values are negative. The petrographic, cathodoluminescence, and isotopic characteristics consistently indicate that the study area is dominated by a reflux infiltration dolomitization model with relatively high-magnesium brine and the results are shown in Fig. 10 . 5.2.2 Dissolution Multiphase dissolution is one of the key factors in the formation of secondary pores in the Fei-3 Member of the study area (SU YX 2023 ). Core and thin section analyses reveal typical dissolution characteristics, and comprehensive studies indicate that the Fei-3 Member dolomite underwent three stages of dissolution (early, middle, and late) to form dissolution-type pores. The first stage is penecontemporaneous dissolution, which is crucial for the formation of numerous pores in the Fei-3 Member dolomite. The shallow-water carbonate platform depositional system (including grain shoals and biogenic reefs) experienced periodic exposure above sea level or immersion in freshwater lenses during relative sea-level fall. During exposure stages, CO₂-enriched meteoric water leaching dominated the formation of characteristic pore systems. Selective dissolution mainly targeted unstable mineral components such as aragonite and high-Mg calcite, forming secondary pores including intragranular dissolution pores, moldic pores, and intergranular dissolution pores. Non-selective dissolution created dissolution fracture networks. Petrographic evidence shows that the pore networks formed by early dissolution significantly improved the porosity-permeability parameters of the dolomite reservoir. The second stage is middle burial dissolution, which was intense and caused non-selective rock dissolution. It dissolved intergranular calcite cement or enlarged intercrystalline pores and residual primary intergranular pores through dissolution, forming numerous secondary pores including intragranular dissolution pores, intergranular dissolution pores, intercrystalline dissolution pores, and vugs. Some of these were partially or completely filled by bitumen and bitumen films on pore walls. Bitumen content shows a positive correlation with current porosity, and most dissolution pores from this stage were preserved, forming excellent reservoir spaces. The third stage is late burial dissolution. Due to the Himalayan orogeny at the end of the Cretaceous, the Feixianguan Formation was folded and uplifted, forming fractures along which dissolution created dissolution fractures and vugs. This diagenetic event was relatively weak, with the fracture-vug system mainly occurring in dense lithofacies such as micritic limestone and micritic dolomite. Its spatial distribution often coexists with contemporaneous mega-to-coarse crystalline calcite veins. Geochemical evidence indicates that such tectonic-fluid activities occurred after hydrocarbon migration, and their formation mechanism may involve the activation of thermochemical sulfate reduction. 6. Conclusions (1) The Fei-3 Member dolomite reservoir mainly develops grain dolomite, silt-crystalline dolomite, and fine-crystalline dolomite lithofacies. Its pore system is characterized by a combination of intercrystalline pores (accounting for 52% of total porosity) with intercrystalline dissolution pores and crystalline grain dissolution pores. Overall physical properties are good but show significant spatial heterogeneity. Porosity-permeability parameters are positively correlated with crystal size, and reservoir quality is significantly better than contemporaneous limestone reservoirs. (1) Geochemical characteristics show: positive δ¹³C and negative δ¹⁸O values are related to meteoric water leaching and gas generation; major and trace elements reflect differences in sedimentary salinity and dolomitization intensity; high FeO and MnO values and dark cathodoluminescence indicate an early diagenetic reducing environment; low total rare earth elements and positive Ce anomalies suggest an overall reducing environment, though the bioclastic algal shoal (microbial mat) microfacies shows localized oxidation due to biological activity, contrasting with grain shoal microfacies. (1) Reservoir development is controlled by multiple factors: high-energy depositional microfacies (oolitic shoals and arenaceous shoals) provide the foundation for primary pores; dolomitization mainly follows a high-Mg brine reflux infiltration pattern, with intensity decreasing from northeast to southwest; early-middle stage dissolution is the main cause of secondary pores, while late fracture-related dissolution contributes limitedly. The coupling of dolomitization and multiphase dissolution is key to the formation of high-quality reservoirs. Declarations No potential conflict of interest was reported by the author(s).

Introduction","content":"\u003cp\u003eGlobal carbonate reservoirs account for 38% of the world's total proven hydrocarbon reserves, with marine carbonate rocks contributing up to 60% of large oil and gas fields. Among these, dolomite reservoirs represent a critical exploration target worldwide (Yang Y et al. 2024; Zhang Dw 2021;Janjuhah HT et al. 2021). The Third Member of the Feixianguan Formation (hereafter referred to as Fei-3 Member) in the Puguang Gas Field is a typical marine carbonate reservoir. Although four industrial gas wells have been drilled (accounting for 7% of Puguang's total reserves), its recovery rate remains as low as 9.15%, leaving substantial untapped resources with significant exploration potential. However, its unique geological setting and complex diagenetic evolution pose key scientific challenges for reserve evaluation and exploitation.\u003c/p\u003e\u003cp\u003eThe T\u003csub\u003e1\u003c/sub\u003ef\u003csub\u003e3\u003c/sub\u003e was deposited in an Early Triassic restricted platform environment, with burial depths generally exceeding 4,500 m (locally\u0026thinsp;\u0026gt;\u0026thinsp;6,000 m), overburden pressures\u0026thinsp;\u0026gt;\u0026thinsp;150 MPa, and formation temperatures of 120\u0026ndash;220\u0026deg;C\u0026mdash;conditions that profoundly influence diagenesis and fluid activities. Multiphase tectonic uplift/subsidence has subjected the reservoir to epigenetic dissolution, deep overpressure, and thermochemical sulfate reduction (TSR), resulting in a complex multi-genetic pore system (Liu X et al. 2022;Wen W et al. \u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e2023\u003c/span\u003e). Some scholars proposed that high-quality reservoirs result from synergistic effects of favorable sedimentary facies, epigenetic dissolution, deep overpressure, and TSR-induced dissolution, with TSR and hydrocarbon overpressure being critical for porosity enhancement(Ma YS et al. \u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e2007\u003c/span\u003e). In contrast, Some researchers emphasized the dominance of penecontemporaneous reflux dolomitization, suggesting that evaporative reef-shoal facies are more conducive to reservoir development (Jiang XQ et al. 2014). Several studies highlighted the decisive role of eogenetic dissolution in porosity formation (Yang WQ et al. \u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e2023\u003c/span\u003e). Nevertheless, despite extensive research on T1f3 dolomite reservoirs, key controversies persist: (1) The coupling mechanism between sedimentation and diagenesis remains unclear due to insufficient systematic studies; (2) Quantitative characterization of dolomitization processes is lacking, with unresolved contributions of different mechanisms (e.g., evaporation-pumping, reflux infiltration, burial dolomitization) to reservoir quality; (3) The stages of dissolution and their controls on porosity evolution remain debated. These knowledge gaps severely constrain further exploration.\u003c/p\u003e\u003cp\u003eTo address these challenges, this study integrates core/thin-section observations, cathodoluminescence (CL), and C-O isotope analyses to systematically investigate the genetic mechanisms of dolomite reservoirs, providing theoretical foundations for optimized hydrocarbon exploration in the Puguang Gas Field.\u003c/p\u003e"},{"header":"2. Research Background","content":"\u003cp\u003eThe Puguang Gas Field, located in the northeastern Sichuan Basin, is situated at the northern margin tectonic belt of the Yangtze Craton, adjacent to the Qinling Orogenic Belt (Fig.\u0026nbsp;\u003cspan refid=\"Fig1\" class=\"InternalRef\"\u003e1\u003c/span\u003ea). Within the Sichuan Basin, the lithology of the Lower Triassic Feixianguan Formation exhibits a gradual eastward decrease in terrigenous clastic material and a corresponding increase in pure carbonate deposits. Based on this characteristic, the region can be broadly divided into three zones: the western clastic rock zone, the central transitional lithology zone, and the eastern carbonate rock zone. The Feixianguan Formation maintains conformable contact relationships with both its overlying and underlying strata.By the late Feixianguan depositional stage, continuous sea-level fall transformed the northeastern Sichuan Basin into a stable platform environment, yielding alternating purple-red, gray-purple, and yellow-gray argillaceous\u0026ndash;micritic carbonates of variable thickness. Lithologies include argillaceous dolomite, micritic dolomite, mudstone, argillaceous limestone, and micritic limestone, reflecting a marine-to-terrestrial transitional setting (Zhang JZ et al.2011). The Fei-3 Member (111.4\u0026ndash;149 m thick) predominantly comprises restricted platform facies, with gray micritic dolomite, micritic limestone, and mixed carbonate rocks interbedded with grain-supported deposits (e.g., grainstone dolomite, oolitic limestone, and oolitic dolomite) and local mudstone/dolomite interlayers. Four microfacies are identified: grain shoals, bioclastic-algal mats (microbialites), oolitic shoals, and lime flats, collectively representing a transgressive systems tract (L PW et al.2013). The sedimentary profile (Fig.\u0026nbsp;\u003cspan refid=\"Fig1\" class=\"InternalRef\"\u003e1\u003c/span\u003eb) indicates a transition to a gently sloping epeiric sea-like platform during Fei-3 deposition, with intra-platform shoals and microbial mats developed on paleo-highs, while lime flats and dolomite flats dominated lows.\u003c/p\u003e\u003cp\u003e\u003c/p\u003e"},{"header":"3.

First, the 200-mesh powdered samples were dried in an oven at 105\u0026deg;C for 3\u0026ndash;4 hours, then immediately transferred to a desiccator and cooled for 8 hours before weighing. Approximately 1.5 g of each sample was accurately weighed into a crucible that had been cleaned with alcohol and air-dried. The crucibles were placed in a muffle furnace at 920\u0026deg;C and ignited for 3 hours, with no more than 35 samples heated simultaneously. After ignition, the crucibles were transferred while still hot into a desiccator and cooled to room temperature for 3 hours before weighing. Weighing was conducted within 2 hours in a constant-temperature environment maintained at 25\u0026deg;C. The LOI was calculated based on the mass difference between the crucible with sample and the empty crucible (assuming constant crucible mass).\u003c/p\u003e\u003cp\u003eA 0.6 g aliquot of the pre-ignited sample was mixed uniformly with anhydrous lithium tetraborate flux (Li₂B₄O₇) at a ratio of 1:8. The mixture was placed in a platinum crucible, followed by the addition of one drop of a mixed flux consisting of 1% LiBr and 0.5% NH₄I. Fusion was carried out at 1250\u0026deg;C using an Analymate-V8C four-head high-frequency fusion machine to produce glass beads. If cracks or opacity were observed in the glass beads, the fusion process was repeated. The glass beads were analyzed using a Rigaku RIX 100e X-ray fluorescence spectrometer (XRF). The concentrations of major elements were calculated based on a bivariate fitted working curve established using 36 silicate reference materials. Corrections were applied using the Traill-Lachance empirical algorithm, and the analytical precision was generally better than 2%\u0026ndash;5%.

Approximately 40 mg of dried 200-mesh powder samples and reference standards were accurately weighed and placed in pre-cleaned Teflon bombs.A mixture of purified 1:1 HNO₃, HF, and HClO₄ was added sequentially. The samples were subjected to ultrasonic oscillation for 1 hour to ensure homogeneous mixing and then placed on a hotplate and evaporated to dryness after 3 days of constant-temperature heating.Subsequently, purified 1:1 HNO₃ and HF were added again to the dried samples, with care taken to avoid sample loss. The bombs were sealed and placed in an oven at 190\u0026deg;C for 48 hours. After heating, the oven door was opened and allowed to cool for 1 hour before removal.A volume of 4 mL of 4N HNO₃ was added to each sample, followed by 30 minutes of ultrasonication. The samples were then returned to the oven and heated at 170\u0026deg;C for 4 hours. After heating, the samples were promptly diluted 2000-fold and spiked with an Rh internal standard solution (1:1) to correct for instrumental drift.Reference materials included USGS standards W-2, G-2, BHVO-1, and Chinese national rock standards GSR-1, GSR-2, and GSR-3, along with a procedural blank. The final analyses were conducted by Senior Engineer Xianglin Tu using a PerkinElmer Sciex Elan 6000 inductively coupled plasma mass spectrometer (ICP-MS). The analytical precision was generally better than 5%.

The results indicate that the Fei-3 Member reservoir rocks are predominantly composed of dolomite, with a minor amount of limestone.The dolomites in the Fei-3 Member can be classified into the following structural types: oolitic dolomite, residual oolitic dolomite, medium-crystalline dolomite, fine-crystalline dolomite, and silt-crystalline dolomite.\u003c/p\u003e\u003cdiv id=\"Sec10\" class=\"Section3\"\u003e\u003ch2\u003e4.1.1 Grain Dolomite\u003c/h2\u003e\u003cp\u003eGrain dolomites mainly include grainstone dolomite, oolitic dolomite, and residual oolitic dolomite.

The ooids measure 2\u0026ndash;3 mm in diameter, showing poor sorting but good rounding. The ooid interiors are replaced by dolomite, while the intergranular spaces are cemented by micritic to silt-crystalline and sparry dolomite. The rock retains its original structure, with microscopic observations revealing typical concentric ooid layers. Additionally, the first-stage marine cement, characterized by an isopachous rim structure, is identified within intergranular pores. This suggests that the rock formed through early dolomitization of oolitic limestone.\u003c/p\u003e\u003cp\u003eResidual oolitic dolomite is primarily composed of dolomitized residual ooids and algal grains (content exceeding 60%), with observable residual ooid textures or ghost structures (Fig.\u0026nbsp;\u003cspan refid=\"Fig2\" class=\"InternalRef\"\u003e2\u003c/span\u003ec, d). It is inferred that this rock type originated from intense dolomitization and recrystallization of oolitic limestone, influenced by meteoric freshwater dissolution, resulting in common intragranular dissolution pores.\u003c/p\u003e\u003c/div\u003e\u003cdiv id=\"Sec11\" class=\"Section3\"\u003e\u003ch2\u003e4.1.2 Crystalline Dolomite\u003c/h2\u003e\u003cp\u003eBased on crystal size variations, this rock type can be classified into medium-crystalline, fine-crystalline, silt-crystalline, micritic dolomite, and various transitional lithologies. Among these, silt-crystalline and fine-crystalline dolomites are the most widely distributed, forming the predominant components of this category.Medium-crystalline dolomite exhibits a light gray to brownish-gray appearance and is primarily composed of medium-grained dolomite crystals (Fig.\u0026nbsp;\u003cspan refid=\"Fig2\" class=\"InternalRef\"\u003e2\u003c/span\u003e). Microscopic observations reveal that the crystals are predominantly subhedral in shape, displaying a mosaic texture, with occasional dusty rims or ghost structures of original grains.The fine-crystalline dolomite lithofacies predominantly exhibits brownish-gray, light gray, and yellowish-gray hues. Mineralogically, it is primarily composed of fine-crystalline dolomite with grain sizes ranging from 0.1 to 0.25 mm (Fig.\u0026nbsp;\u003cspan refid=\"Fig2\" class=\"InternalRef\"\u003e2\u003c/span\u003e). Microscopic observations reveal that the crystals are predominantly euhedral to subhedral in form, with local development of anhedral crystals. Distinctive \"dusty rim\" textures and grain ghost structures are commonly observed. The rock often contains calcareous or argillaceous inclusions. Comprehensive studies indicate that this lithofacies formed through intense dolomitization of precursor grainstones, with the original sedimentary structures nearly completely obliterated.\u003c/p\u003e\u003cp\u003eThe silt-crystalline dolomite lithofacies is characterized by light gray to yellowish-gray coloration, with mineral composition dominated by silt-grade dolomite crystals (0.05\u0026ndash;0.1 mm in size).

Integrated research suggests that this lithofacies originated from penecontemporaneous dolomitization of low-energy lime mud deposits. The rock exhibits high compactness with weak dissolution features. The pore system is predominantly composed of intercrystalline pores, locally containing minor dissolution vugs. Porosity parameters range between 2% and 5%, indicating moderate reservoir qualityres, often lined with bitumen. Consequently, dissolution plays a significant role in the formation of these reservoir spaces.\u003c/p\u003e\u003c/div\u003e\u003c/div\u003e\u003cdiv id=\"Sec12\" class=\"Section2\"\u003e\u003ch2\u003e4.2 Reservoir Space Types\u003c/h2\u003e\u003cdiv id=\"Sec13\" class=\"Section3\"\u003e\u003ch2\u003e4.2.1 Intercontinental Pores, Intercrystalline (Grain) DissolutionPores, and Oversized Dissolution Pores\u003c/h2\u003e\u003cp\u003eIntercrystalline pores are formed by the recrystallization of dolomite crystals of varying sizes, which are randomly arranged within the rock. These pores represent the primary reservoir space in the study area, accounting for 52% of the total porosity.

These pores are commonly observed in oolitic dolomites and arenaceous dolomites, primarily formed by the dissolution and enlargement of intergranular cements or matrix. Their development is closely associated with the dissolution of cements or matrix in grain-supported structures, making them typical secondary porosity types.In the Fei-3 Member of the study area, fine- to medium-crystalline dolomites exhibit the most developed intercrystalline (grain) porosity.

The pores include intragranular pores, intragranular dissolution pores, and moldic pores, with pore diameters ranging from 1 to 15 mm.

Some scholars, through petrographic studies, suggest that the formation of crystalline dolomite should be attributed to burial dolomitization.\u003c/p\u003e\u003cp\u003eIn the study area, the Z-values of the Fei-3 Member are all around 130, indicating saline seawater and belonging to the high-salinity dolomitization model. This model mainly includes the evaporation pumping and reflux infiltration modes, emphasizing the importance of evaporation in dolomitization.\u003c/p\u003e\u003cp\u003eThe evaporation pumping dolomitization manifests as a penecontemporaneous alteration process of supratidal surface sediments in tropical environments, with its mechanism consisting of three key stages: first, continuous evaporation of interstitial water leads to salinity enrichment (negative δ\u0026sup1;⁸O values), promoting gypsum precipitation to form high-magnesium brine (Mg/Ca\u0026thinsp;\u0026gt;\u0026thinsp;8); second, the high-magnesium fluid migrates inversely through capillary action, triggering the dolomite conversion reaction of aragonite particles; finally, characteristic gypsum nodules form at the petrographic level, and this mineral assemblage constitutes the hallmark product of evaporation pumping.\u003c/p\u003e\u003cp\u003eIn contrast, the reflux infiltration mode is characterized by the gravity-driven downward migration of high-density brine into deeper sedimentary layers, primarily acting on early diagenetic carbonate bodies to form metasomatic dolomite through replacement reactions. The spatiotemporal differences between the two processes are as follows: evaporation pumping is strictly controlled by the supratidal surface environment (burial depth\u0026thinsp;\u0026lt;\u0026thinsp;3m) and belongs to penecontemporaneous diagenetic events; reflux infiltration continues into the middle-late diagenetic stages and is commonly found at sequence boundaries in paleotopographic depressions.\u003c/p\u003e\u003cp\u003eMicroscopic examination of the Fei-3 Member dolomite revealed no gypsum minerals, with dolomite commonly displaying a \"dusty core and bright rim\" structure. Cathodoluminescence analysis shows low-intensity luminescence, appearing dark yellow to dark brown overall, with patchy luminescence observed in some areas. Microscopic observation indicates that most dolomite crystals exhibit a zonal luminescence pattern with high brightness at the center and low brightness at the edges, and this luminescence characteristic is correlated with the diagenesis of the \"dusty core and bright rim\" structure. The δ\u0026sup1;\u0026sup3;C values of dolomite in the study area are positive, while δ\u0026sup1;⁸O values are negative.

Core and thin section analyses reveal typical dissolution characteristics, and comprehensive studies indicate that the Fei-3 Member dolomite underwent three stages of dissolution (early, middle, and late) to form dissolution-type pores.\u003c/p\u003e\u003cp\u003eThe first stage is penecontemporaneous dissolution, which is crucial for the formation of numerous pores in the Fei-3 Member dolomite. The shallow-water carbonate platform depositional system (including grain shoals and biogenic reefs) experienced periodic exposure above sea level or immersion in freshwater lenses during relative sea-level fall. During exposure stages, CO₂-enriched meteoric water leaching dominated the formation of characteristic pore systems. Selective dissolution mainly targeted unstable mineral components such as aragonite and high-Mg calcite, forming secondary pores including intragranular dissolution pores, moldic pores, and intergranular dissolution pores. Non-selective dissolution created dissolution fracture networks. Petrographic evidence shows that the pore networks formed by early dissolution significantly improved the porosity-permeability parameters of the dolomite reservoir.\u003c/p\u003e\u003cp\u003eThe second stage is middle burial dissolution, which was intense and caused non-selective rock dissolution. It dissolved intergranular calcite cement or enlarged intercrystalline pores and residual primary intergranular pores through dissolution, forming numerous secondary pores including intragranular dissolution pores, intergranular dissolution pores, intercrystalline dissolution pores, and vugs. Some of these were partially or completely filled by bitumen and bitumen films on pore walls. Bitumen content shows a positive correlation with current porosity, and most dissolution pores from this stage were preserved, forming excellent reservoir spaces.\u003c/p\u003e\u003cp\u003eThe third stage is late burial dissolution. Due to the Himalayan orogeny at the end of the Cretaceous, the Feixianguan Formation was folded and uplifted, forming fractures along which dissolution created dissolution fractures and vugs. This diagenetic event was relatively weak, with the fracture-vug system mainly occurring in dense lithofacies such as micritic limestone and micritic dolomite. Its spatial distribution often coexists with contemporaneous mega-to-coarse crystalline calcite veins. Geochemical evidence indicates that such tectonic-fluid activities occurred after hydrocarbon migration, and their formation mechanism may involve the activation of thermochemical sulfate reduction.\u003c/p\u003e\u003c/div\u003e\u003c/div\u003e"},{"header":"6.

Furthermore, the genetic mechanisms of dolomite reservoirs in the study area are discussed.\u003c/p\u003e\u003cp\u003eThe results indicate that dolomite is widely developed in the study area, primarily consisting of grain dolomite and crystalline dolomite. The main reservoir lithologies include grain dolomite, fine-crystalline dolomite, and silt-crystalline dolomite, with medium-crystalline dolomite being the least abundant. The reservoir space comprise intercrystalline pores, intergranular dissolution pores, oversized dissolution pores, intragranular pores, intragranular dissolution pores, and moldic pores. C-O isotopes exhibit positive δ\u0026sup1;\u0026sup3;C and negative δ\u0026sup1;⁸O values, with Z-values around 130, confirming a saline marine origin. Major and trace elements reflect variations in seawater salinity and dolomitization intensity. High FeO and MnO contents, along with cathodoluminescence characteristics, indicate a reducing environment during early diagenesis. Rare earth element patterns show overall low concentrations with positive Ce anomalies, further supporting a predominantly reducing environment, though redox conditions vary slightly among different lithologies.\u003c/p\u003e\u003cp\u003eOolitic shoals and grainstone shoals constitute the material foundation for reservoir development, while dolomitization and dissolution are key factors in reservoir formation.

This study enhances the understanding of the genetic mechanisms of dolomite reservoirs in the Third Member of the Feixianguan Formation in the Puguang Gas Field, providing theoretical support for future exploration and development.\u003c/p\u003e","manuscriptTitle":"Characteristics and Genetic Mechanism of Dolomite Reservoirs:the case study of the Third Member of the Feixianguan Formation in the Puguang Gas Field, Sichuan, China","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-09-22 09:53:12","doi":"10.21203/rs.3.rs-7587834/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2025-10-08T12:41:11+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-10-07T09:18:59+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-09-26T13:14:37+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"126306079717080764261144841432980064533","date":"2025-09-24T07:31:54+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"120669255378217351176773560356814154094","date":"2025-09-22T02:34:38+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-09-11T13:10:28+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2025-09-11T13:03:15+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2025-09-11T06:45:07+00:00","index":"","fulltext":""},{"type":"submitted","content":"Carbonates and Evaporites","date":"2025-09-11T04:57:08+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"carbonates-and-evaporites","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"caev","sideBox":"Learn more about [Carbonates and Evaporites](http://link.springer.com/journal/13146)","snPcode":"13146","submissionUrl":"https://submission.nature.com/new-submission/13146/3","title":"Carbonates and Evaporites","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"em","reportingPortfolio":"Springer Hybrid","inReviewEnabled":true,"inReviewRevisionsEnabled":false}}],"origin":"","ownerIdentity":"4cfdb9ec-c03d-40ae-bdbe-f93314b7feb5","owner":[],"postedDate":"September 22nd, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"under-review","subjectAreas":[],"tags":[],"updatedAt":"2026-04-13T16:54:52+00:00","versionOfRecord":[],"versionCreatedAt":"2025-09-22 09:53:12","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-7587834","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-7587834","identity":"rs-7587834","version":["v1"]},"buildId":"XKTyCvWXoU3ODBz1xrDgd","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
