现场应用取得了较好的效果。

Abstract

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.
