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.
