摘要： 开发研制环保、高效、多功能的油井清蜡降黏剂,是未来清防蜡剂的发展方向。在对不同性能表面活性剂及助剂对蜡的分散性、清蜡性能以及对大港油田稠油的降黏效果评价基础上,筛选出了性能好的烷基苯磺酸盐ABL、酰胺非离子表面活性剂XE 和木质素磺酸盐EM,通过正交试验优选出油井清蜡降黏剂配方组成,并对其综合性能进行了评价。结果表明,配方F6（ABL、XE）样品溶液稳定,且对蜡沉积物的分散性能好,具有较好的清蜡性能和降黏性能,对混合蜡的清蜡率和对大港油田稠油的降黏率分别达到98%和99%.

Abstract: To develop the viscosity reducer characterized by environmental protection, efficiency, multiple functions for paraffin removal in oil well is the direction for meeting the needs for oil production with different contents of paraffin in the future. Based on the evaluations of the effects of different surfactants and additives on paraffin dispersion, paraffin removal and viscosity reducing efficiency of Dagang heavy oils, the alkylbenzene sulfonates (ABL), amide nonionic surfactant (XE) and lignosulfonate (EM) were screened out to optimize the formulations and composite performance of the viscosity reducer by orthogonal test. The results show that the solution of formulation F6 (ABL and XE) is of stability, good for the dispersion of wax sediments and better for paraffin removal and viscosity reduction. The lab study indicates that the viscosity reduction rate and paraffin removal rate are 98% and 99%, respectively.

Key words: paraffin removal, viscosity reduction, dispersion, high pour-point oil, heavy oil
