简要介绍了表面活性剂的润湿性表征方法及润湿剂种类，并从亲水基带电类型、位置和数量以及疏水基链长、结构和是否含有苯环等多个角度，详细综述了三次采油方面，不同结构表面活性剂包括双子表面活性剂对油湿性固体表面润湿性的改变规律及机理。图2 参36

Methods for characterizing the wettability and types of wetting agents were briefly described in this paper. From multiple angles including the charged type，location and quantity of the hydrophilic group as well as the chain length，the structure of the hydrophobic group and whether there is a benzene ring or not，the rules and mechanism for wettability alteration of oil-wet solid surface by different surfactants including Gemini surfactant in aspects of EOR were overviewed in detail.
