下寺湾油田深部调驱体系和调驱参数的优化

Optimization of control-flooding system and control-flood parameters in the deep part of Xiasiwan Oilfield

本文探讨适合下寺湾油田油藏条件的一种冻胶调驱体系配方,设计实验进行分析,结果表明选择0.2PV调驱体系用量,此时在油藏综合含水率低于50%时,能够提升采收率增加值,达到良好的调驱效果。

This paper discusses the formulation of a gel gel control and flooding system suitable for the reservoir conditions of Xiasiwan Oilfield,and designs and analyzes the experiment. The result shows that the dosage of 0.2PV control and flooding system is selected. At this time,when the comprehensive water content of the reservoir is lower than 50%,which can increase the value of recovery factor and achieve a good effect of regulating and flooding.
