摘　　要：断块油藏在胜利油区占有重要的地位,目前普遍进入高含水开发期。在缺乏新增储量补充的情况下,如何大幅度提高老区采收率是胜利断块油藏开发的主要问题。针对断块多、矛盾复杂的现状,在继承以往断块分类基础上,结合开发矛盾对断块油藏重新分为4大类7小类并进行认识,首次提出了屋脊断块油藏人工边水驱技术、极复杂断块油藏立体组合开发技术和复杂断块油藏均衡水驱开发技术等提高采收率对策。各项技术对策在胜利油区典型断块试验区的实践和推广取得了明显的效果,人工边水驱在东辛油田辛1沙-4块提高采收率7.5%;立体组合开发技术使永安油田永3-1复杂断块提高采出程度7.6%;均衡水驱开发技术在永3复杂断块沙二7-9区提高采收率4.1%。实现断块油藏在高含水期持续高效开发。There are many fault blocks in Shengli oil area and complex development contradictions. On the basis of the previous classification of fault blocks,the fault block reservoirs in Shengli oil area are redivided into 4 main categories and 7 subtypes according to the development contradictions. According to the outstanding development contradiction of various types of oil reservoirs,the countermeasures for enhanced oil recovery are put forward,such as the artificial edge water flooding development for fastigium fault block reservoirs,the three-dimensional combination development for extremely complex fault block reservoirs and the balanced water flooding development for complex fault block reservoirs. The implementation of the countermeasures in the typical fault blocks of Shengli oil area achieved a significant effect： the artificial edge water flooding in Xin 1 sha-4 fault block of Dongxin oilfield enhanced oil recovery by7. 5%; the three-dimensional combination development in Yong3-1 extremely complex fault block reservoir of Yongan oilfield enhanced oil recovery by 7. 6%; the balanced water flooding development in Shaer 7-9 area of Yong3 complex fault block enhanced oil recovery by4. 1%. The implementation of these technical countermeasures will achieve continuous and efficient development of fault block reservoirs in high water cut stage.
