Abstract:

The sodium clay and AM monomer are blended together ,br tenelacting with initiator and crosslinker at 130℃. In the system of the blending gel the formulation is as follow: sodium clay 6%, AM 6%～7%,initiating agent Y100mg/L～200mg/L and crosslinker J 1%～1.5%.Because of the sodium clay, the gel time is delayed and the thermal stability is enhanced. The intensity of the blending gel is intensively high and the ability of blocking is comparatively good, so as temperature water shutoff agent the system has a good prospect to be use.

Key words: sodium clay, blending gel, high intensity, temperature-resistant water shutoff agent
