提高断块油藏采收率技术研究

Study for Tech of Increasing Fault-Block Reservoir Recovering Ratio.

针对濮城油田断块油藏非均质严重、采收率低等问题,通过剩余油类型及其分布分析,提出了该类油藏提高采收率的措施和技术支持。依靠多元配套技术,完善注采井网,提高驱油控制储量,从而提高区块采收率。

To the problems of heterogenous, low recovery and eomplex fault-block reservoir in Pucheng oilfield and analyzing the remaining oil types and distribution, the paper gives out method and technique for guaranteeing to increase the discovery of this oilfield. Depending on sets of polytechnic methods and completed injection-production pattern, the oil-drive controlling reserve is increased which to enhance recovery of district and block.
