摘　　要：输送含蜡原油一直我国原油管输所面临的主要技术问题,一方面要保障含蜡原油的顺畅输送,另一方面还要考虑节能、安全等问题。对国内外原油降凝剂技术的发展概况和降凝剂的作用机理和类型进行归纳总结以及列举现场实例。另外,针对凝剂技术目前存在的问题和降凝剂技术发展趋势进行了分析。The main technical problems of transporting waxy crude oil with pipeline have been faced by our country. On the one hand, the smooth transportation of waxy crude oil must be ensured;on the other hand, energy saving and security and other issues need be considered. In this paper, development situation of the dewaxing technology at home and abroad was discussed as well as action mechanism and types of pour point depressant. In addition, problems in the current dewaxing technology were analyzed as well as development trend of the pour point depressant.
