摘　　要：针对孤岛油区断块油藏关系多、油水关系复杂、含水上升快、采收率低等问题 ,从储层平面、层间、层内分析剩余油分布规律和下一步增产挖潜方向 ,提出了该类油藏提高采收率的对策和技术保障。通过综合治理 ,累积增油 61 7kt,增加可采储量 5 0kt。Gudao oilfield belongs to fault-block oilfield.It has many series of strata,its oil-water relationship is complex,its water cut raises high and its recovery is low.Based on the geologic characteristics of fault-block oilfield,this paper analyzes the residual oil distribution in the layer,interlayer and place,and gives methods and technique guarantees to increase the recovery of this oilfield.The total oil production has increased 61.7×10 4t and the recoverable reserves has increased 53×10 4t by intergrated adjustment.
