| Abstract: | 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. |
