摘　　要：以强碱重烷基苯磺酸盐为基础原料,加入混合剂A进行复配得到弱碱表面活性剂,研究了弱碱化下界面张力的情况,室内评价结果表明,这种表面活性剂具有良好的界面活性,配制的复合体系在较宽的表面活性剂浓度和碱浓度范围可与原油形成10^(-3)mN/m数景级的超低界面张力。The weak base surfaetant was prepared using heavy alkyl benzene sulfonate and the compound agents A. The interfacial tension of the surfactant under the weak base was researched. The results showed that the surfactant had a good surface activity, the interracial tension of the prepared composite system was 10 ^-3 mN/m magnitude in wide concentration of alkaline and surfaetant.
