影响萨中南一区西东块一类油层聚合物驱各站采收率因素研究

萨中南一区西东块一类油层聚合物驱4个注入站提高采收率差异较大,分析研究影响提高采收率的各种因素,对指导聚合驱驱油方案的合理优化设计、进一步提高聚驱开发水平具有很好的指导意义。主要从水淹程度、含油饱和度、老水井排、注采完善程度、套损、注入参数等因素对采收率的影响进行分析。

There is the large difference in improving the recovery rate of four injection stations from the south one area east west block Sazhong developing area polymer flooding of the main reservoir.We analysis the influence of various factors to improve oil recovery.This will guide the optimization design of polymer flooding,flooding scheme to further enhance the level of polymer flooding is a good guide.This article mainly analyzes that the factors such as the water flooded degree,oil saturation,the old well row,perfect degree of injection-production,casing failure,injection parameters influence the recovery rate.
