摘　　要：研究以自制的丙烯酸十八醇醚酯单体(A)、马来酸酐(M)、苯乙烯(S)为单体进行共聚反应,制得一种油溶性稠油降粘剂AMS。确定了AMS合成的最佳条件:丙烯酸十八醇醚酯、苯乙烯、马来酸酐摩尔比为5∶1∶3,反应温度为90℃,引发剂BPO用量为0.6%,反应时间为6 h。结果表明,在温度为50℃时,降黏剂AMS加量为0.6%时对渣油的降粘率达到54.11%。此外,加入0.2%助剂Span-80能进一步提高AMS降粘效果,当剪切速率为2 000 r/min时AMS的降粘效果可达90%以上。The oil-soluble viscosity depressant was synthesized by maleic anhydride,styrene and octadecyl acrylate（ AMS）. Results show that octadecyl acrylate,styrene and maleic anhydride monomer ratio for 5∶ 1∶ 3,dosage of initiator is 0. 6%,under the influence of synthetic temperature 90 ℃ when the reaction time is 6 h,the effect of AMS was the best. The result showed that when the temperature is 50 ℃,the best usage of 0. 6%,the ratio of viscosity reduction of residue oil was 54. 11%. Besides,when the best dosage of Span-80 was 0. 2% and the shear rate is 2 000 r / min,the ratio of viscosity reduction of residue oil exceeded 90%.
