摘　　要：由丙烯酰胺改性单体ＤＥＡＭ与ＡＭ、ＡＡ共聚合成了三元共聚物ＣＵＰＦ－３１５，研究了影响共聚反应的主要因素、共聚物的结构、共聚物在溶液中的抗盐、抗剪切降解性和热稳定性。在实验条件下ＣＵＰＦ－３１５的耐温抗盐性优于Ｐｆｉｚｅｒ公司的ＨＰＡＭ３４３０Ｓ和Ｐｈｉｌｉｐｓ公司的耐温抗盐聚合物ＨＥ－１００。A terpolymer for EOR in hostile environments is prepared from acrylamide,N, N-diethylacrylamide and acrylic acid by initiated copolymerization in aqueous solution. The optimal molar ratio of the monomers in reaction mixture and the coplymerzation conditions are established for the highest solution viscosity (8-9 mPa·s for 2000 ppm solution in brine containing 800 ppm Ca￣(2+),200 ppm Mg￣(2+) and 99000 ppm Na￣+ +Cl￣+) and the highest characteristic viscosity(1000 ml/g).The thermal stability in the brine of CUPF-315 is higher than that of Phillips' HPAM 3430S and that of Philips HE-100.
