摘要：

针对目前各油田聚合物驱转为水驱后，一般出现含水上升快，产油量大幅度下降的情况，以及油层内残余的大量聚合物未得到利用，而目前开发的残余聚合物再利用技术存在一些缺点，未得到推广应用，研制出新型复合处理剂JY-8。新型复合处理剂JY-8可与聚合物形成强度较高的凝胶体，将地层内残余聚合物有效地固定和絮凝，是很好的固定剂和絮凝剂，实现了“二剂合一”，达到对地层进行深部调剖、驱油的目的；同时，通过调整复合处理剂JY-8的加量等可调节成胶时间和凝胶强度。室内评价和现场应用表明，与以前的技术相比，复合处理剂JY-8可使油层内的残余聚合物利用率从原来的8％提高到15.65％，使聚合物驱后续水驱的采收率增加值从原来的10.33％提高到18.1％，在油井上起到了很好的增油、控水效果。

Abstract:

According to water cut common rapid increase,oil production great decrease, a lot of unutilized residual polymers in the reservoir,no extension application of residual polymers reutilization technologies because of some reasons at present, since all oil fields change polymer flooding to water flooding,this paper develops a new composite treating agent JY-8.The new composite treating agent JY-8 is a good fixative and flocculant,which can form heigh strength gel with polymers, consolidate and flocculate residual polymers in the reservoir effectively, realize unification of two agents, achieve goals of deep profile control and oil displacement for the formations,at the same time, gelation time and gel strength can be regulated by adjusting used-amount of new composite treating agent JY-8. laboratory evaluations and field applications indicate that new composite treating agent JY-8 increases utilization ratio of residual polymers in the reservoir from 8％ to 15.65％, increases recovery ratio of water flooding after polymer flooding from 10.33％ to 18.1％, plays a good oil increment effect on oil wells,while contrasting to previous technologies.

Key words: consolidation, flocculation, composite treating agent JY-8, residual polymers, polymer injection block
