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。
Base on strong base heavy alkylbenzene sulfonate as raw material, mixed agent A was mixed to obtain weak base surfactant, and the interfacial tension under weak base was studied. The indoor evaluation results show that this surfactant has Good interfacial activity and the prepared composite system can form ultra-low interfacial tension of 10-3 mN / m with crude oil in a wide range of surfactant concentration and alkali concentration.
