The system consists of a high temperature resistant functional polymer and a delay crosslinking agent monomer under high temperature conditions. Under the strengthening effect of nano-strengthening stabilizer, a high and high salt resistant polymer gel plugging agent is formed. The product has  high gel strength ( above G level ), the strength is stable, the viscoelasticity is excellent, and the injection is good. It can be applied to oilfield profile control and water plugging.

Technology Index：

Temperature resistance above 150 °C;  Salt resistance up to 200,000 mg / L;  It is resistant to calcium and magnesium up to 10000 mg / L ;  The gelation time can be adjusted.
