摘　　要：随着新发现油气藏物性的复杂化及对油田开发效果要求的不断提高,聚合物和表面活性剂作为油田开发中常用化学剂,它们的性能面临巨大挑战。综述了抗温抗盐增黏性共聚物和抗温抗盐低界面张力表面活性剂的研究进展。探讨了特性官能团抗温抗盐的机理,指出了抗温抗盐增黏性共聚物和抗温抗盐低界面张力表面活性剂在分子结构上的共性。对新型抗温抗盐型驱油剂的分子结构设计进行了展望。As the physical properties of newly discovered oil and gas reservoirs become more and more complicated and the requirements for oilfield development effect are constantly improved,polymer and surfactant,as the commonly used chemical agents in oilfield development,encounter great challenges in their properties.The research progress of temperature and salt resistant,viscosityenhancing copolymers and temperature and salt resistant low interfacial tension surfactants was summarized.The mechanism of temperature and salt resistance of characteristic functional groups was discussed,and the similarities of molecular structure between temperature and salt resistant,viscosity-enhancing copolymers and temperature and salt resistant low interfacial tension surfactants were concluded.How to design a new molecular structure with temperature and salt resistance for oil displacement is prospected.
