| Abstract: | A new water swelling heat and salt resistant water shutoff agent SAP was synthesized with acrylic acid, acrylamide, 2 - acrylamido - 2 - methyl propane sulfonic acid and bentonite as the materials. According to the results of performance evaluation, the salinity tolerance of this water shutoff agent is 10% or higher, and this water shutoff agent can be used at the temperature up to 125 ~C. It has good oil -and -water selectivity, can improve the heterogeneity of formation, and adjust the injection profile. Water shutoff agent SAP can be used as a selective water shutoff agent in oil and gas field development with good application value. |
