摘要
讨论了石油磺酸盐Ｂ－１００体系／大庆原油间的界面张力等值图以及Ｎａ＿２ＣＯ＿３，３３３０Ｓ聚合物对Ｂ－１００体系／大庆原油间界面张力等值图的影响，分析了Ｎａ＿２ＣＯ＿３体系／大庆原油间界面张力等值图。并对Ｂ－１００－Ｎａ＿２ＣＯ＿３体系和Ｂ－１００－Ｎａ＿２ＣＯ＿３－３３３０Ｓ体系与大庆原油间能够形成超低界面张力的机理进行了探讨。在表面活性剂浓度很低时，三元复合体系与大庆原油间的界面张力仍可维持在超低范围内。
Abstract The isograph of interfacial tensions between the petroleum sulfonate B-100 system/Daqing crude oil was studied.The effects of Na_2CO_3 and 3330S polymer on it was also diss-cussed and the isograph of interfacial tensions Na_2CO_3 system/Daqing crude oil was ana-lyzed. The mechanism of ultralow tension between the systems of B-100-Na_zCO_3 and B-100-Na_2CO_3-3330S and Daqing crude oil was explained.When concentration of surfactant islower, the interfacial tensions of triaxial composite system/Daqing crude oil are still withinthe range of ultralow.
