针对三元复合驱中碱的注入所带来的采出液处理困难以及对地层造成损害等问题，运用新型甜菜碱表面活性剂BHJ，论述了不加碱又能达到低界面张力聚合物/表面活性剂二元驱油体系性能。综合所有均质和非均质岩心的实验结果并通过分析，我们认为采用甜菜碱BHJ活性剂的无碱二元驱油体系驱油效果好于采用Ss的弱碱（Na2CO3）三元体系和采用Sy的强碱（NaOH）三元体系。

In this paper, we discussed the base ASP flooding caused by the injection of produced fluid as well as dealing with difficult issues such as formation damage, and we put forward the use of new betaine surfactant BHJ to maintain the low interfacial tension of polymer / Binary surfactant flooding system without the add of base. According to the analysis of the results of experiments on the homogeneous cores and heterogeneous cores, we considered that the non-alkali binary compound flooding system with sulfosalicylic surfactant BHJ have a better effect of flooding than the sodium hydroxide ternary alkali flooding system and the Ss weak-alkali ternary system.
