摘　　要：以环氧琥珀酸、乙烯基三乙氧基硅烷和丙烯酸为原料,偶氮二异丁腈为引发剂,通过共聚反应合成了有机硅三元共聚物(EAVT)阻垢剂。探讨了聚合反应条件对EAVT阻钙垢性能的影响,并对EAVT对单一垢及复合垢的阻垢性能进行了评价。结果表明,较佳合成条件为反应温度65℃、反应时间4 h、引发剂用量6%、环氧琥珀酸、丙烯酸与乙烯基三乙氧基硅烷物质的量之比0.8∶1∶0.8。当EAVT用量为100 mg/L时,其对某油田地层水中钙镁垢和钡锶垢的阻垢率分别为88.28%和87.26%。The organosilicon terpolymer scale inhibitor(EAVT)was synthesized by copolymerization of epoxy succinic acid,vinyl triethoxysilane and acrylic acid as starting materials and azobisisobutyronitrile as initiator.The influence of polymerization conditions on the performance of EAVT calcium scale inhibition was explored,and the performance of EAVT on single scale and composite scale was evaluated.The results show that the optimal synthesis conditions are that under the temperature of 65℃,4 hours,6 wt%of initiator,and the ratio of 0.8∶1∶0.8(epoxy succinic acid,acrylic acid,and vinyl triethoxysilane).When EAVT is 100 mg/L,its scale inhibition rates for calcium magnesium scale and barium strontium scale in the formation water of a certain oilfield are 88.28%and 87.26%,respectively.
