摘　　要：以丙烯酸、丙烯酰胺、2-丙烯酰胺基-2-甲基丙磺酸等为主要原料,合成了一种新型的抗温吸水性树脂-SAP。SAP较优的反应配方及反应条件为:AA∶AMPS∶AM单体配比2∶2∶6、交联剂用量2.5%、引发剂用量0.4%、pH值为4。性能评价结果表明,SAP在淡水和盐水中均具有较好的吸水膨胀性能,而在油相中基本上不膨胀,SAP抗NaCl可达15%,抗温可达130℃。在油田开发中,SAP可以作为堵水调剖剂或选择性堵水剂使用,具有较好的应用价值。A new temperature resistance and absorbent resin named SAP was successfully prepared based on acrylic acid(AA),acrylic amide(AM) and 2-acrylamido-2-methyl propane sulfonic acid(AMPS).The optimum composition and reaction conditions include AA∶AMPS∶AM monomer ratio of 2∶2∶6,the usage of cross linking agent of 2.5%,the usage of initiator 0.4%,pH of 4.The result of performance evaluation indicates that SAP both in fresh and salt water has a good water swelling property,but it does not swell basically in oil.Its NaCl resistance is up to 15%,and temperature resistance is up to 130℃.In oilfield development,SAP can be used as water shutoff and profile control agent or selective blocking agent,has good application value.
