一种适合高矿化度油藏的调剖剂研制

摘要

In high salinity formation,the anionic polymer in traditional profile agent interacts with Ca2+,Mg2+,which is more easy to form precipitation but gel. The study developed a kind of profile control agent which is suitable for high salinity formation,and studies the effect of gelling by analyzing the relationship between the amount of each component and the experimental factors of profile system. It shows that the profile control agent of zwitterionic polymer is stable,the gelling effect is good.%在高矿化度地层中,传统调剖剂中的阴离子聚合物会与Ca2+、Mg2+ 反应产生沉淀,不易形成冻胶.实验研制了一种适用于高矿化度地层的调剖剂,并对调剖体系的各组分用量及实验影响因素对成胶效果的影响作出评价.实验表明两性离子聚合物调剖剂性能稳定,成胶效果很好.
