摘　　要：双子表面活性剂具有临界胶束浓度低、水溶性好、胶束结构和聚集行为异常、降低油水界面张力效率高、流变性能好等特点,引起了学术界和现场专家的广泛关注。流变特性和界面张力的测定是评价和选择提高采收率(EOR)药剂的两项重要筛选技术。对双子表面活性剂的流变性、润湿性变化、吸附和界面性质做了分析,对双子表面活性剂在提高采收率中的应用研究现状做出总结分析。Unique properties of gemini surfactants, such as low critical micelle concentration, good water solubility, unusual micelle structures and aggregation behavior, high efficiency in reducing oil/water interfacial tension, and interesting rheological properties have attracted the attention of academic researchers and field experts. Rheological characterization and determination of the interfacial tension are two of the most important screening techniques for the evaluation and selection of chemicals for enhanced oil recovery(EOR). In this paper, the rheological properties, wettability changes, adsorption and interface properties of Gemini surfactants were analyzed, and the application of Gemini surfactants in EOR was summarized and analyzed.
