摘要
国内原油（包括海洋油田的原油）大都是含蜡黏稠原油和重质高黏易凝原油，这两种类型的原油流动性能差。采用添加降凝剂的方法是改善含蜡原油低温流变特性的途径之一。文中重点介绍了AM（丙烯酰胺）／AA（丙烯酸）／AE（烷基酚聚氧乙烯醚丙烯酸酯）共聚物型降凝剂的性能，系统研究了聚合体系单体质量分数和反应温度对共聚物特性黏数的影响，讨论了共聚物含量对含蜡原油流动性的影响，最后得出添加降凝剂的方法对含蜡原油的输送起到重要作用的结论。
Most of our country＇s crude oils（ including crude oils from its marine oil fields）have two kinds：one is thick and waxy, the other is heavy, highly viseoous and condensated. The flow properties of these two types of crude oils are poor. Adding the freezing point depressant is one of the ways to improve the low-temperature theological behavior of waxy crude oil. Focusing on the performance of AM （aerylamide）/AA （ acrylic acid ）/AE （ alkyl phenol polyethyleneoxide ether acrylic ester） eopolymer freezing point depressant, this paper makes a systematic study of the effect of the polymerization system monomer density and the reaction temperature on the copolymer inherent viscosity,discusses the influence of the copolymer content on the waxy crude fluidity. Then a conclusion is drawn that adding the pour point depressant plays a crucial role in transmission of the waxy crude.
