Abstract
Based on a lot of relevant references at home and abroad,this paper elaborates the flooding mechanism and means of oil displacement after water flooding. The studies show that water alternating CO2 injection is the best injection method after water flooding through comparative analysis of injection means: continuous CO2 injection. It also analyzed the feasibility of CO2 flooding in reservoirs after water flooding,and showed a good application prospect for high water reservoir in China.
