摘　　要：针对油田高含水期断层边部剩余油富集规律认识不清和有效挖潜难等问题,以松辽盆地杏南油田北断块葡萄花油层为解剖对象,利用三维地震、测井曲线和生产动态等资料,分析断层边部断砂配置关系、储层砂体发育特征、油层沉积演化序列和单砂体开发动用状况等,得出断层边部剩余油平面富集部位受控于断砂配置关系影响下的单砂体开发动用状况,以及垂向富集层位受控于油层沉积演化序列和储层砂体发育特征控制下的中厚层河道发育层位,建立油田高含水期断层边部剩余油富集规律及定向井挖潜方法,为老油田增储稳产提供有利保障.During high water cut stage,it is unknown for remaining oil accumulation rules difficult to develop along fault.Taking Putaohua reservoir of north fault block of Xinnan oilfield,Songliao basin as an example,this paper analyzed the match relationship of fault and reservoir at the edge of faults,reservoir sandbody development characteristics,reservoir sedimentary evolution sequence and single sandbody developing situation by 3Dseismic,logging curve and production performance data.It can be concluded that remaining oil accumulation parts in plane was affected by single sandbody developing situation af-fected by the match relationship of fault and reservoir.In vertical,accumulation parts were affected by reservoir sedimentary evolution sequence and medium thickness river channel by reservoir sandbody development characteristics.Finally a theoretical method of remaining oil accumulation rules during high water cut stage and developing for directional well is established,which provides security for maturing field to increase reserves and maintain production.
