| 摘 要： | 聚驱后油层中残留着大量聚合物，为了进一步提高采收率，选择了一种阳离子聚合物絮凝剂，絮凝剂在水溶液中溶胀，形成具有一定粘弹性的微米级颗粒，对岩心的封堵率大于97%；溶入水的部分能够絮凝地层残留的聚合物，起到驱油的效果，提高原油采收率10%以上

| Abstract: | a large number of polymer left in the oil layer after polymer flooding. In order to further enhance oil recovery, a special cationic polymer flocculant was select. Flocculants can swell in the water and form some micron particles which had certain viscoelasticity. The core plugging rate is more than 97%. The flocculant which dissolved in the water can flocculate the residual polymer in the layer and has the flooding effect. It can enhanced oil recovery more than 10%. |

| Keywords: | Residual polymer Flocculant Profile modification Plugging rate |
