摘　　要：在 2 98K用静态法测定了乙醇、NaOH和PAA存在时十二烷基苯磺酸钠SDBS在石英砂上的吸附等温线 ,观测了上述各助剂对SDBS在石英砂上吸附的影响规律。本工作实验结果及文献发表的驱油烷基苯磺酸盐在油砂上的吸附实验数据 ,可用改进的非均匀表面两阶段吸附模型关联。The isotherms and the amount of adsorption of sodium dodecylbenzene sulfonate(SDBS) on quartz sand from solution with ethanol, NaOH or polyarcylic acid added as accessory for EOR are measured at 298K. The effects of the accessories on SDBS adsorption are discussed. The experimental data obtained as well as the experimental data published elswhere for systems of commercial alkylbenzene sulfonates and reservoir sand are correlated with a modified nonuniform surface two step adsorption model.
