摘　　要：研究了不同碳链长度醇及混合醇对石油磺酸盐/疏水缔合聚合物二元复合体系界面张力的影响。研究表明,醇与石油磺酸盐具有很好的协同效应,醇的加入降低了油/水界面张力;在石油磺酸盐浓度为1000mg/L,醇的浓度为1000mg/L时,C4-C12及混合醇均能使油/水界面张力达到10-3 mN/m;混合表面活性剂与单独石油磺酸盐相比达到超低界面张力的时间更短,使用浓度更低。The effects of alcohols with various carbon chain lengths and mixed alcohols on the interfacial tension of petroleum sulfonate/hydrophobically associated polymer binary combination flooding system were studied.The study indicates that the alcohols have good synergistic effect with petroleum sulfonate.By adding the alcohols,the oil/water interfacial tension is reduced.When petroleum sulfonate's concentration is 1000mg/L and alcohol's is 1000mg/L,the C4-C12 and mixed alcohols can decrease oil/water interfacial tension to 10-3mN/m.Therefore,compared with petroleum sulfonate alone,the mixed surfactants can achieve ultra-low interfacial tension in shorter time and lower concentrations.
