摘　　要：按照种类分别对表面活性剂型、聚合型、复配型3种降凝剂进行了论述,阐述了降凝的作用机理以及降凝剂的选择原则,提出了当前降凝剂存在的问题,指出了降凝剂的发展和改进方向。At present,most of crude oil produced in China belongs to high-condensation waxy crude oil,which has poor fluidity and stoppage at low temperature,and is likely to cause condensate tube accidents,bringing a heavy negative impact on crude oil transportation,processing,storage,etc.Therefore it is very important to develop coagulants.Surfactant,polymer and compound types of pour point depressants are respectively described.The action mechanism and selection principles of pour point depressant are analyzed,the existing problems are listed,and the development and improvement direction are proposed.

关 键 词：降凝剂 作用机理 降凝效果 选择原则 发展方向
