摘　　要：以克拉马依七东一区原油为油相 ,用自制的棉籽底油单乙醇胺硫酸酯盐和棉籽底油单乙醇胺为复合驱油体系 ,讨论了 ASP复合体系的协同效应以及各组分对界面张力的影响 .结果表明 ,该体系有很好的协同效应 ,在Na CL浓度为 3% ,钙镁离子浓度为 2 0 0 mg/L的情况下仍能形成 1 0 - 3 m N/m数量级的低界面张力 .Some research work on phase test was carried out with cross-test design, using Alkanolamide Sulfate System Combined With Alkylalcoholamide as surfactant, selected Kelamayi crude oil as oil phase, the composition of composite deoil system was obtained. The factors affecting surface tension and the synergic effects were studied by determination of instantaneous interface tension. The alkaline-surfactant combination flooding system containing the surfactant, sodium chloride and alkali can produce ultra-low interfacial tension (10\{-3\}mN/m order) against Kelamayi crude oil.
