摘　　要：针对大港油田采油八区稠油凝点高,粘度较大,开采、集输的困难,对添加HG-D型多效降粘剂(由含长链乙烯基的聚合物、非离子表面活性剂和多种石油馏分类有机溶剂及加重剂等组成,不含氯和硫)进行了室内研究。结果表明:该多效降粘剂具有较好的降凝、降粘和清蜡防蜡的多种效果,降粘幅度平均达到50％左右,凝点可降至0℃左右;清蜡速率大于3mg/(mL·min)。该剂有一定的防蜡效果,可以代替单纯的清蜡剂。The viscous crude oil of the 8th square of Dagang Oilfield has the difficurty for onrecovery due to its high pour point and high viscosity. A HG-D type multifunctional viscosity reducerfree of chlorine and sulfur formulated by a polymer contained long-chain ethylenic base, a non-ion sur-face active agent, and a gravity increasing agent was added to the crude oil in the laboratory. The resultshowed that the said viscosity reducer had good effects on pour point depressing, viscosity reducing andparaffin removal. The average viscosity reduced around 50%; the pour point depressed to about 0℃;and the paraffin removal rate was more than 3mg/mL min. The said viscosity reducer had certain paraf-fin removing effect, which could replace the paraffin remover.
