摘要
采用深部处理剂JY-8与聚合物形成强度较大的凝胶体,作为地层内残余聚合物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;成胶时间和凝胶强度可通过JY-8的加入量等进行调节。室内评价和现场应用结果表明,与以前的技术相比,深部处理剂JY-8可使油层内的残余聚合物利用率从原来的8%提高至15.65%,使聚合物驱后续水驱的采收率增加值从原来的10.3%提高至18.1%,在油井上起到了很好的增油、控水效果。
This paper describes a new deep treating agent JY-8.The new deep treating agent JY-8 is a good fixative and flocculant,which can form high strength gels with polymers,consolidating and flocculating residual polymers in the reservoir effectively,realizing unification of the two agents,and achieving the 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 the used-amount of the new deep treating agent JY-8.Laboratory evaluations and field applications indicated that new deep treating agent JY-8 increased utilization ratio of residual polymers in the reservoir from 8% to 15.65%,increased recovery ratio of water flooding after polymer flooding from 10.3% to 18.1%,and played a good oil increment effect on oil wells.
