摘　　要：胡状油田处于高含水期,常规的调驱技术已不能满足生产需求。针对胡状油田储层非均质性强的特征,近年来开展了体膨型聚合物调驱技术的矿场试验和应用研究,该技术解决了常规调驱剂存在的注入性及可驱动性差的问题,有效地缓解了储层层内矛盾,取得了较好的增油降水效果,为高含水期油藏提高采收率探索了一条新途径。As Huzhuang oilfield has entered high water - cut stage,the conventional profile control agent could not meet the production demands.Field testing and applied researches of expanded profile control agent have been carried out due to strong reservoir heterogeneity in Huzhuang oilfield.The results show the technology has solved the problems occurred to conventional profile agent such as poor injection effect and poor driving performance,alleviated the interlayer interference and achieved obvious effect of increased oil and decreased water.In one word,the expanded profile control agent provides a new approach for improving oil recovery at high water - cut stage.
