摘　　要：稠油中沥青质及胶质的含量高 ,凝固点及粘度高 ,对稠油的生产、运输都比常规原油困难 ,所以对稠油降粘剂的研究及其作用机理探讨具有重要意义。用苯乙烯 (S)、甲基丙烯酸甲酯 (MMA)及丙烯酰胺 (AM )在一定温度、溶剂条件下进行聚合 ,然后与高碳醇进行酯交换反应 ,得到三元共聚酯化物—梳状聚合物。性能评价实验结果表明 ,根据稠油特点进行分子设计 ,合成出的降粘剂具有良好的降粘效果。讨论了合成条件 (如温度、合成时间、原料配比、引发剂用量等 )对产品降粘效果的影响 。The production and transportation of viscous crude are more difficult than normal crude oil because the high content of asphaltene and gum. A comb polymer-terpolymer ester is obtained by polymerizing styrene (S), methyl metharylate (MMA) and acrylamide (AM) then the produced terpolymer reacts with a higher alcohol (ester exchange). Results of evaluation on performance have showed that the comb polymer has good viscosity-reducing effect. The influence of synthetic conditions on the viscosity-reducing effect has been discussed and the mechanism of the viscosity reducer has been analyzed.
