摘　　要：在原油中添加降凝剂能够有效地改善原油的流变性,降低原油凝固点,使之达到低温输送,节能降耗的目的。列举了三条比较典型的采用添加降凝剂输送工艺管线,充分体现添加降凝剂输送工艺所带来的好处。对国内外降凝剂发展历史进行了研究整理,在种类繁多的降凝剂中选取了适合我国各地不同原油的降凝剂。Adding pour point depressant in crude oil can effectively improve the rheological properties of the crude oil and reduce the freezing point to transport crude oil at low temperature and to achieve the purpose of saving energy and reducing consumption. In this paper, three typical pipelines with pour point depressant delivery process were introduced, and the benefits of using pour point depressant delivery process were embodied. The development history of the pour point depressant at home and aboard was researched, and how to select the suitable pour point depressant for different crude oil in China was discussed.
