摘要
以丙烯酸高碳酯和马来酸酐为原料,通过过硫酸铵引发聚合制备了原油降凝剂,对陕北某油井原油降凝效果良好。最佳合成条件为:单体物质的量之比为5∶1,引发剂用量为0.8%,反应温度为65℃,反应时间为6h。并对引发剂用量和降凝剂用量对降凝效果的影响进行了评价。
Using acrylic acid high carbon ester and malefic anhydride,crude oil pour point depressants was pre-pared by radical polymerization. And the optimum reaction conditions were obtained by orthogonal experiment as follows：molar ratio of malefic anhydride/ammonium chloride is 5：1,addition amount of initiator is 0. 8%,reaction temperature is 65℃,and reaction time is 6h.
