摘要
聚合物驱油在国内许多油田已广泛应用,试井在聚合物驱油藏中用的越来越多。本文介绍了确定聚驱前缘响应时间的三种方法及复合储层内区半径的计算方法,结合实际验证了方法的可靠性。同时以大庆油田某一典型区块聚合物驱油井在不同年份的试井测试数据为基础,解释大量油井,总结规律,最后以一口典型井说明聚合物驱油的一些特征。
Polymer flooding has been used in many oil fields, and well testing is developing in polymer flooding reservoir. The paper introduces three methods of the responding time before the polymer flooding and calculation method of composite system＇s inner region radius, and validate them with practice. Meanwhile, through the analysis of oil wells based on the different years well testing data in one typical region of Daqing Oilfield, rules are summarized, and one topic well＇s analysis result is used to show some characteristics of polymer flooding.
