摘要： 针对目前砂岩油藏二类油层开发过程中存在动用程度低、高含水、原油采收率低等问题，提出一套井网、多套层系、注聚开发、逐层上返开发二类油层的方法。对大庆杏十二区葡I1-2层上返注聚孔隙体积、注入速度、注聚合物量、段塞组合等参数进行了优化。结果表明，对杏十二区葡I1-2层进行上返注聚开发，当注入量为1 PV，注入速度为0.16 PV/a，注聚合物量为1 200 mg/L⋅PV，先注入高质量浓度聚合物段塞，再注入低质量浓度聚合物段塞，采收率达到了50.11%，较预测水驱采收率提高了10.1%。

Abstract: In view of the problems existing in the development of the second⁃class reservoirs in sandstone reservoirs,such as low utilization degree,high water⁃bearing and low oil recovery rate,a set of well pattern, multiple sets of layers,polymer flooding,and the method of reverse⁃exploiting second⁃class reservoirs layer by layer was proposed.The parameters such as pore volume,injection rate, polymer injection volume and slug combination were optimized by numerical simulation in Pu I1-2 layers of Daqing Xing Twelve area.The results showed that when the PV number was 1 PV,the injection rate was 0.16 PV/a,the polymer injection volume was 1 200 mg/L⋅PV,the high⁃concentration polymer slug was injected first, then the low⁃concentration polymer slug was injected,and the recovery rate reached 50.11%.Compared with the predicted water flooding recovery rate,it was improved by 10.1%.
