摘要
本文研究了仲烷基磺酸盐(SAS)水溶液与烷烃,大庆模拟油的低界面张力性能,考察了醇和无机盐的种类和用量对低界面张力性能的影响。在实验条件下获得油/水低界面张力为10^(-3)～10^(-4)毫牛顿/米,这对三次采油的研究工作具有实际意义。
Low interracial tension behaviors-between aqueous solutions of SAS and alkanes, ineluding oil phase imitated to Daqing crude oil are studied. The effects of type and quantity of alcohols and inorganic salts on low interracial tension are examined. The value of low interfacial tension obtained between oil and water ranged from 10^(-3) to 10^(-4)mN/m, which had a. practical meaning for research work on tertiary oil recovery.
