摘　　要：以丙烯酰胺(AM)、2-丙烯酰胺-2-甲基丙磺酸(AMPS)为原料,采用水分散聚合法,制备双水相聚合物(NPAM)。相对分子量为380万,粒子分布集中,且粒径小,平均粒径为182.7 nm。室内评价聚合物的减阻效果,其在清水中减阻率达到80%,在10%的盐水中减阻率达到77%。黏弹性能分析,NPAM的抗应变能力较强。双水相聚合物可用作减阻剂,为油气田压裂作业提供优秀的减阻性能。Aqueous two-phase polymer(NPAM)was synthesized by aqueous dispersion polymerization using acrylamide(AM)and 2-acrylamide-2-methylpropanesulfonic acid(AMPS)as raw materials.The results showed that the relative molecular weight of NPAM was 3.8 million,the particle distribution was concentrated and the particle size was small,and the average particle size was 182.7 nm.The drag reduction effect of polymer was evaluated in laboratory,and the drag reduction rate reached 80%in clean water and 77%in 10%salt water.According to the analysis of viscoelastic properties,NPAM has strong strain resistance.Aqueous two-phase polymer can be used as drag reducer to provide excellent drag reduction performance for oil and gas field fracturing operation.
