Abstract: In this paper, the influence of the adsorption characteristics, percolation characteristics and solution properties of the new salt-resistant polymer on the oil displacement effect was studied by using the laboratory percolation experiment and core oil displacement experiment. The results show that the incorporation of AMPS monomers into polymer chains can effectively inhibit the degradation of polymer chains by divalent ions such as calcium, magnesium, iron and sulfur in the formation, and significantly improve their salt resistance. After 5 times of dynamic adsorption, the viscosity retention rate of salt resistant polymer is 24.20% higher than that of common polymer. At the same concentration, the viscosity of salt resistant polymer is twice that of ordinary polymer, and the resistance coefficient and residual resistance coefficient are smaller than those of ordinary polymer. The structure of salt resistant polymer is more linear and has better injection performance. The total oil recovery of salt resistant polymer is 3.5% higher than that of common polymer, and the EOR of unit dosage polymer is 8.5% higher than that of common polymer.
