摘　　要：表面活性剂是一种具有亲水基团和亲油基团的物质,在渗吸驱油过程中表现出改变岩石润湿性、降低油水界面张力、乳化原油、增加岩石表面电荷密度及防止沥青质沉淀的作用。本文概述了不同类型表面活性剂作为渗吸驱油剂的优缺点及研究现状,归纳了表面活性剂复配和纳米颗粒强化展现出的技术优势,并展望了表面活性剂作为渗吸驱油剂的未来发展方向。Surfactant is a substance with hydrophilic groups and lipophilic groups,which can change rock wettability,reduce oil-water interfacial tension,emulsify crude oil,increase rock surface charge density and prevent asphaltene from precipitating during the imbibition flooding.In this paper,the advantages,disadvantages and research status of different types of surfactants as imbibition oil displacement agents were overviewed.The technical advantages exhibited by surfactant compounding and nanoparticle reinforcement were summarized.And the future development direction of surfactants as imbibition oil displacement agents was prospected.
