摘　　要：作为我国石油资源重要组成部分的低渗透油藏,由于其储层非常致密、孔隙度小、渗透率低、渗流阻力大等特点,通常导致采油过程中油层的吸水能力下降,注水压力上升,注水驱替压力较高等问题。近年来,表面活性剂降压增注技术越来越受关注。在总结表面活性剂降压增注原理的基础上,从不同表面活性剂类型(阴离子型、非离子型、双子型、两性表面活性剂和复配型表面活性剂)的角度总结了表面活性剂降压增注技术的发展现状,并对今后该技术的发展方向进行了展望。Low permeability reservoirs,as an important part of China's petroleum resources,are usually characterized by tight reservoirs,small porosity,low permeability and high seepage resistance,which lead to water absorption capacity decline,water injection pressure rise and high-water injection displacement pressure.In recent years,the technology of reducing pressure and increasing injection by surfactant has attracted more and more attention.On the basis of summarizing the principle of reducing pressure and increasing injection of surfactants,this paper summarized the development status of the technology of reducing pressure and increasing injection of surfactants from different types of surfactants(anionic surfactants,non-ionic surfactants,gemini surfactants,amphoteric surfactants and compound surfactants),and advancedits development direction in the future.
