论述了小集油田复杂断块油藏特“双高”阶段提高水驱采收率的主要做法:在加强油藏精细研究,深化油藏认识,搞清剩余油分布规律的基础上,针对区块套损井多、剩余油较为分散的特点,通过应用井网重建,老井侧钻、层系简化,油层复查,周期注水等技术手段,挖掘剩余油潜力,小集油田复杂断块油藏特“双高”阶段提高水驱采收率的做法为类似油田后期开发具有一定的借鉴作用。 The main practice of improving waterflood recovery in the special “double high” phase of the complex fault block reservoir in Xiaoti oilfield is discussed: on the basis of strengthening the fine reservoir research, deepening reservoir understanding and clarifying the distribution of remaining oil, In view of the characteristics of wellbore encroachment and residual oil dispersed, the potential of remaining oil is tapped through the application of well pattern reconstruction, sidetracking of old wells, stratigraphic simplification, oil layer review and periodic water injection. The complex fault blocks The practice of increasing waterflood oil recovery in reservoir special “double high ” stage has some reference for similar oil field development in the later period.
