摘　　要：水驱油藏开发后期,靠水驱来提高采收率,效果已不太明显。要想较好地挖掘层内剩余油,就必须有既提高波及系数,也有提高洗油效率的提高原油采收率的技术。针对PC2-403井组的开发现状及存在的主要问题,为了解决开发中出现的矛盾,研究并实施了AMPS交联聚合物驱油体系,现场应用效果明显。Effects of EOR through water injection are not ideal in late development stage of waterflooding oilfield. In order to better recover the by - passed oil in reservoirs, EOR technologies that can improve both sweep efficiency and flushing efficiency are needed. In view of the current status of exploitation and the major problems existed in PC 2-403 well group, AMPS weak corsslinked polymer system is formulated and applied, and the field application effects are good.
