摘　　要：针对高温和高矿化度油田,以丙烯酰胺(AM)、丙烯酸(AA)、2-丙烯酰胺基-2-甲基丙磺酸(AMPS)、二甲基二烯丙基氯化铵(DMDAAC)为原料,合成了 AM/AA/AMPS/DMDAAC 共聚物,确定了最佳合成条件:反应时间6 h,单体总质量分数10%,AMPS 含量10%,反应温度35℃,反应体系为弱碱性。对此共聚物性能进行了评价,结果表明,此共聚物具有优良的耐温抗盐性能,并具有很好的抗老化能力。A heat - tolerant and salt - resistant AM/AA/AMPS/DMDAAC copolymer for high temperature and high salinity oilfield was synthesized with AM, AA, AMPS and DMDAAC as raw materials. The optimum synthetic condition was determined as follows：reaction time 6h, total monomer mass fraction 10 %, AMPS concentration 10 %, reaction temperature 35 ℃, with a alkalescent reaction system. The result of evaluation on the copolymer performance showed that it had excellent heat- tolerant and salt- resistant performance and anti - aging ability.
