断块油藏高含水期剩余油分布特征及分区控水技术研究

Residual Oil Distribution Characteristics and Zonal Water Control Technology of Fault-Block Reservoir in High Water Cut Period

在油气资源开发过程中,由于断块油藏的构造复杂性,进入高含水期后,其剩余油分布情况较为复杂,且存在着较大的区域性差异。因此需要针对不同的区域,采用不同的技术,制定出有效的剩余油挖潜对策。基于此,对断块油藏高含水期剩余油分布特征及控水稳油技术展开了探究。

In the specific development process of oil and gas resources,due to the structural complexity of fault-block reservoirs,after entering the high water-cut period,the remaining oil distribution is more complicated,and there are large regional differences.Therefore,it is necessary to adopt different technologies for different areas to develop effective strategies to tap the potential of remaining oil.Based on this,this paper explores the remaining oil distribution characteristics and water-controlling and oil-stabilizing technologies in fault-block reservoirs during high water-cut periods.
