The temperature resistance, salt resistance and rheological properties of the polymer were tested by viscometer and rheometer. The change of polymer microstructure in salt solution was analyzed by scanning electron microscopy. The viscosity test results showed that when the polymer concentration was higher than CAC, the polymer solution exhibited good salt resistance and presented good salt thickening performance. The effect of temperature on the salt resistance of polymer solution showed different rules. With the increase in temperature, the resistance of the polymer to NaCl decreased gradually, while the resistance of the polymer to CaCl 2 increased first and then decreased. The resistance of the polymer to CaCl 2 showed a special temperature response. Viscoelastic and shear tests showed that the polymer possessed more robust resistance to extreme sodium chloride concentration than extreme calcium chloride concentration. Electron microscopy analysis suggested that the microstructure of the polymer gradually became dense and compact in the salt solution. The results showed that this novel non-ionic hydrophobically associating polymer possessed potential application value in ultra-high salinity reservoirs.
