摘　　要：选择两种吸水膨胀橡胶(Water Swellable Rubber)作为堵水剂,测试其在清水和1%的NaCl溶液中的膨胀率,并进行室内岩心封堵和热失重实验。实验结果表明,吸水膨胀橡胶在55℃清水中的膨胀率高达650%、热失重率小于3%,对裂缝有很强的封堵能力。Two kinds of Water Swellable Rubber were used as blocking agent. Two kinds of rubber＇s swellable rate in the fresh water and 1% NaCl were tested. Core blockage and weight loss were tested in laboratory. The laboratory findings indicate that water swellable rubber in the fresh water comes to 650% ,weight loss less than 2%, and has superior sealing characteristics.

关 键 词：吸水膨胀橡胶 膨胀率 裂缝堵水 热稳定性
