摘要
双河油田438块ⅠⅡ1-2层系目前已进入水驱开发特高含水阶段,为保证二元复合驱矿场应用效果,本文通过开展非均质仿真模型二元复合驱实验,给出适用于研究区块二元复合驱注入参数的技术界限:表面活性剂最佳浓度为0.3%,段塞大小为0.4PV;并对二元复合驱影响因素进行分析,为双河二元驱提高采收率现场试验提供理论基础。
438 zoneⅠⅡ1-2 layer system of Shuanghe oilfield has entered ultra-high water cut stage.In order to assurance the file result of surfactant/polyment flooding,this paper studies the physical simulation flooding test. Based on this,injection parameters of the surfactant/polyment flooding is suits to research block： optium concentration of surfactant is 0.3% and plug is 0.4PV.Influence factors were analyzed to surfactant/polyment flooding.This research provide theoretical foundation to improve oil recovery in field test of Shuanghe.
