In order to solve the problems of decline continues to increase,carry out the research on the factors affecting the development effect of polymer flooding in the later stage.There are some problems in the small faulted block reservoir He Er Duan of Shuanghe Oilfield, such as strong edge water energy shows low efficiency, irregular well pattern leads to fluid channeling,formation plugging results in a large drop in well fluid production and so on.In order to improve the development effect of polymer flooding in later stage and further enhance oil recovery.Studing the effect of cluster displacement under different injection-production parameters by numerical simulation technology,define reasonable injection-production ratio. The inhibition effects reserched single point cross-flow in different injection-production way by numerical modeling, and draw the best way. Study on radius of oil congestion in polymer flooding stage and come up with reasonable countermeasures,good field application effect had been taken.
