摘　　要：通过大庆油田萨北开发区注聚合物前进行的复合离子深度调剖试验 ,表现出了调剖井注入压力、PI值明显上升 ,高渗透层渗透率变差 ,注入剖面得到改善且稳定时间长 ;产出井产出剖面连续得到改善 ,产液指数下降幅度较大 ,见效时间较聚驱提前等动态变化特征。分析了线状注水井组和特高含水井见效明显的原因。A depth profile controlling experiment of compound ion polymer is performed before the polymer injection in Sabei development area in Daqing Oil Field. The injection and PI value increase, the permeability in high permeable reservoir turns poor, the injection profile is improved, and the stability time is long. The production profile of production well is continuously improved, the produced fluid index decreased rapidly, and the responding time is earlier the polymer flooding. This paper analyzes the reason of the apparent responding of linear water injection well group and super high water cut wells, and illustrates the necessity of the popularization of this technique in polymer flooding blocks.
