周期注水方法在油藏开发中的适用性

Applicability of Cyclic Water Injection in Reservoir Development

周期注水是注水油田改善开发效果的常用方法,在调整油田高含水期工作中起至关重要的作用。文章结合前人研究成果,精炼总结周期注水的驱油机理、相关参数的确定以及注水过程,并根据油田生产实际情况,从油藏适用性的角度出发,总结了周期注水选井条件和效果评价方法,为高含水油藏稳油控水开发提供可借鉴的资料。

Cyclic water injection is a common method to improve the developing effect of water injection oilf ield and plays a vital role in adjusting the high water cut stage oilf ield.Combined with previous research achievements,this paper summarizes the mechanism of cyclic water injection,the determination of related parameters and the water injection process.Based on the actual production conditions of the oilf ield,this paper summarizes the well selection conditions and effect evaluation methods of cyclic water injection from the reservoir applicability,which can be used for reference for the stable oil production and water control development of high water cut stage oilf ield.
