The water absorbent resin is a new type of polymer plugging materials developed in recent years, the water swelling with certain viscoelastic gel, with a certain intensity, strong water retention, salt resistance and stability. Polymerization aqueous solution of acrylic acid (AA), acrylamide (AM) as the experimental materials, the choice of a controllable expansion sealing agent the KP to determine the formula developed by the sealing agent, and has good suction rate, anti-performance of salt and water retention. |
