摘　　要：利用自制的丙烯酸高级酯单体与其它单体共聚合成了一种新型油溶性聚合物降粘剂马来酸酐 苯乙烯 丙烯酸高级酯三元共聚物MSA。研究了该共聚物的合成工艺以及单体配比、加入量、分子量、加入温度等因素对稠油降粘效果的影响 ,得出了最佳单体配比及合成工艺。将该降粘剂工业产品用于吐哈吐玉克油田稠油泵上掺稀举升工艺 ,只要加入 10 0— 2 0 0mg/L降粘剂MSA ,在稀油掺入量比原来降低 5 0 %以上时仍能维持正常生产 ,对该稠油具有明显降粘效果。A maleic anhydride styren C 18 alkylacrylate terpolymer MSA as viscosity reducer for crude oil is prepared as a result of investigating synthesis variables: ratio of monomers, initiator and molecular weight regulator use levels, and reaction time. The viscosity reducing efficiency of MSA for a thinned viscous crude oil and the optimal temperature of introducing MSA into the crude oil are determined. In a 9 days trial on a viscous oil producing well of Tuyuke Oil Field, Turpan Hami, normal oil production maintained with injecting MSA of 100—200 ppm and lowering thinning oil amount to more than 50%.
