摘　　要：通过对喇嘛甸油田聚合物驱单井效果分析 ,给出了采油井阶段效果评价方法 ,即单井见效时间和含水回升时间早晚的确定方法。单井见效时间取决于油层条件、注聚前含油饱和度及累计采出地下体积倍数 ;单井含水回升时间主要取决于聚驱阶段剩余储量采出程度。根据单井阶段评价结果 ,对试验区进行跟踪调整 ,在单井阶段效果评价的基础上 ,对单井最终效果采用吨聚增油量和聚驱阶段剩余储量采收率来进行客观、有效的评价 。A method on evaluation time that water cut fall or rise is given out through analyzing the polymer flooding of single well in Lamadian oilfield. Definite the method for the time that single well becomes effective and water cut risen again sooner or later, the time single well becomes effective depend on the oil reservoir condition ,and the time that water cut risen again depends on the oil extraction level of surplus reserves while polymer flooding.This paper gives the result of the adjustment and evaluates the incremental oil per ton and the surplus reserves recovery ratio of per well carry.This paper is effective on predicting the product oil capacity.
