摘　　要：对大庆油田不同地区原油族组成进行了分析,并测量了胶质沥青质含量不同的原油与三元体系间的界面张力。结果表明,将原油分离出的各组分分别与氢氧化钠溶液、表面活性剂ORS41及三元复合体系作用,其界面张力有明显的差别,这说明在与三元驱油体系形成超低界面张力时,原油性质也有非常重要的影响。Oil components in each block of Daqing oilfield have been analyzed and interfacial tension between ASP system and oil with various asphaltene contents are measured.It demonstrates the interfacial tense changes greatly,when the extracted components react with sodium hydroxide,surfactant ORS41 and ASP system respectively.Oil properties play very important role in forming extra-low interfacial tension between oil and ASP system.
