高含水期剩余油研究方法及影响因素分析

The Research Methods and the Factors Analysis of Remaining Oil at the High Water Cut Stage

经过长期注水开采的油田已经基本进入了高含水期,研究剩余油的分布以及油田开发难度越来越大。高含水期剩余油对于增加可采储量和提高采收率具有很大的潜力,研究剩余油势在必行,主要从成因、影响因素、研究方法三方面进行。

Oilfield falls into the stage of high water-cut after a long-term of exploitation.The research of the remaining oil＇s distribution and oilfield exploitation become increasingly difficult.It＇s very important to increase recoverable reserves and recovery ratio which remaining oil can do at the high water cut stage.The study on the distribution of the remaining oil is consisted of three aspects：the causes of the remaining oil,the factors of the remaining oil and the research methodology of the remaining oil.
