摘　　要：濮城油田当前以进入"高含水、高采出程度、高剩采速度"的深度开发阶段,通过分析该阶段地下剩余油分布的格局和特点,指出油层内剩余油分布零散,但局部仍有相对富集的部位,为此从分析水驱开发油藏采收率现状入手,找出制约因素并对水驱提高采收率方法进行总结,分析油田开发在挖潜对象、研究深度等方面的新变化,摸索出一套针对不同剩余油分布类型的调整对策,进一步提高采收率。PuCheng oilfield has already entered into deep exploitation stage of＂high water-cut,high degree of reserve recovery and high residual exploit speed＂.After analyzing the structure and characteristic underground,we find out that the distribution of remaining oil is scattered,but there＇re still rich areas.Therefore,we can start from analyzing the recovery efficiency of water-drive reservoir,and find out the constraints and conclude methods to improve water-drive recovery efficiency.Through the analysis of new changes in digging places,depth research etc.,we try to find out a set of adjust strategies with respect to different kinds of distribution,and further improve recovery efficiency.
