摘要/Abstract

摘要： 将全馏分重烷基苯切割成一系列窄馏分，磺化后的重烷基苯磺酸盐（HABS）按相对分子质量由小到大编号为HABS-1，3，5，7，9。以新疆八区530原油为油相，地层模拟水为水相，分别测试全馏分和窄馏分重烷基苯磺酸盐对体系界面张力和乳化性能的影响。结果表明：随着窄馏分HABS平均相对分子质量的增大，油水界面张力先减小后增大，当窄馏分HABS的相对分子质量为398（烷基碳链平均碳数为15）时，油水界面张力最低，为0.002 3 mN/m；使用HABS-3与15%的HABS-1、AEO-9复配剂，体系的乳化综合指数达到89.51%、88.70%，油水界面张力分别为0.009 8 mN/m和0.005 9 mN/m，均处于10-3 mN/m的超低水平。

Abstract: Full range heavy alkyl benzene sulfonates were cut into a series of narrow fractions of HABS and then sulfonated. According to their molecular weight, the sulfonated narrow fractions are called HABS-1, 3, 5, 7, 9. The crude oil from Xinjiang 530 oilfield reservoir was used as oil phase, and its formation water in this oilfield as water phase. The effect of full range HABS and narrow fractions on emulsifying stability and interfacial tension (IFT) were measured, respectively. The results showed that the IFT value goes down firstly and then up with the increase of its molecular weight. The HABS with average alkyl carbon chain length of C15 (molecular weight of 398) can reduce the IFT level to 0.002 3 mN/m. The results of stability of oil-in-water emulsion showed that when HABS-3 mixed with HABS-1 (HABS-3:HABS-1=85:15) or with nonionic primary alcohol ethoxylate AEO-9 (HABS-3:AEO-9=85:15), the systems attain strong emulsion stability with emulsion composite index of 89.51% and 88.70%, while the IFT value is 0.009 8 mN/m and 0.005 9 mN/m, respectively, both are at 10-3 mN/m (ultra low) level.
