摘　　要：双子(Gemini)表面活性剂具有高表面活性、低浓度下可形成胶束,并可达到超低IFT(界面张力),并且它还具有很好的耐温性和耐盐性,将此类Gemini表面活性剂应用于油田降压增注具有重要的研究价值。将应用于低渗油藏方面的阴-非离子型、阳离子、非离子和阴离子型双子(Gemini)表面活性剂进行了综述,并对其耐温性、耐盐性、降低界面张力及降压增注能力进行了评述,以期为更多从事相关领域研究的人员提供参考。Gemini surfactants have high surface activity,low concentration can form a glue beam,and can achieve ultra-low IFT(Interface tension),and it has good temperature and salt resistance,the application of such Gemini surfactants to oil field pressure-boosting injection has important research value.This paper reviews the use of anion-nonionic,cationic,nonionic and anionic gemini surfactants in low permeability reservoirs,and reviews their temperature resistance,salt tolerance,reduction of interfacial tension,and decompression and augmented injection capacity,in order to provide reference for more researchers in related fields.
