Accurately comprehending the contribution of output and the dynamic production at the bottomhole of each section of the horizontal well serves as the foundation for water control completion design. This understanding holds immense significance in enhancing gas well productivity, reducing costs, and increasing efficiency. Currently, the dynamic prediction model for horizontal well completion fails to consider the impact of fluid flow direction. To address this gap, the fluid dynamics software CFD(Computational Fluid Dynamics) is employed to analyze the flow patterns and assess the degree of influence of target parameters including permeability distribution, production pressure difference, crude oil viscosity, and density on the fluid within the reservoir and wellbore. The analysis demonstrates that the primary location of the distribution surface in both the reservoir and annulus lies near the wellbore's toe. The number of diversion surfaces correlates with permeability distribution, production pressure difference, crude oil viscosity, and crude oil density. Among these factors, permeability distribution and crude oil viscosity exhibit a greater impact, while production pressure difference and crude oil density have a relatively smaller impact. The research findings hold significant scientific and engineering value for effectively developing bottom water reservoirs, as well as for the production and management of horizontal wells.
