摘要(Abstract)：

针对聚合物驱后油藏提高采收率的需要,在孤岛中一区Ng3开展非均相复合驱实验和矿场试验,描述非均相复合体系的注入产出特征,评价非均相复合驱的封堵调剖性能和驱油效果.实验和矿场试验表明:黏弹性颗粒驱油剂PPG的阻力因数、封堵效率、非均质剖面调整能力强于聚合物的,适合长期驱替应用;非均相复合驱实验提高聚合物驱后采收率13.6%,高于聚驱后二元驱和聚合物加PPG驱二者之和;矿场动态特征不同于聚合物驱和二元驱,纵向吸水剖面发生交替变化,见效井综合含水率呈台阶式直线下降,具有交替封堵、转向式驱替各小层剩余油的特点;增油倍数和综合含水率下降幅度高于同期聚合物驱和二元驱的,可成为聚合物驱后油藏进一步提高原油采收率的有效方法.

关键词(KeyWords)：非均相复合驱;聚合物驱后;封堵调剖;提高采收率;矿场试验
