摘　　要：以原油降凝剂的结构性能应用为基础,综述了几种主要的降凝机理,包括共晶理论、晶核作用理论、吸附理论等,认为对不同的降凝剂来说,降凝机理取决于其化学结构;阐述最影响降凝效果的因素,主要包括原油组成和性质,相对分子质量,胶质-沥青质等9种。Based on the structure characteristics of pour point depressants for crude oil, the depression mechanisms were studied systematically. It is believed that the depression mechanisms depend on the chemical structure of the depressants and the main influencing factors include the composition and quality of crude oil, molecular weight, colloid-pitch, etc.
