摘　　要：研究了电解质 (Na Cl)和助剂醇 (异戊醇 )对石油羧酸盐活性剂体系 (2 #-4 E,2 #-6E)界面活性的影响。实验结果表明 ,在活性剂体系 2 #-4 E和 2 #-6E中加入 Na Cl和异戊醇 ,可大大改善活性剂体系的界面活性 ;加入 NaThe effects of NaCl and isoamylol on the interfacial activities of petroleum carboxylates(2# 4E,2# 6E) are studied The results show that the interfacial activities of surfactant system would be greatly improved by adding NaCl and isoamylol into 2# 4E,2# 6E,the surfactant system added with NaCl and isoamylol could produce ultralow interfacial tension with crude oil from Daqing oilfield with wide ranges of surfactant concentration and salinity
