摘　　要：疏水缔合聚丙烯酰胺(HAPAM)在高温高盐油田中的应用已成为近年来聚驱研究的热点之一。本文介绍了该类聚合物在多孔介质中渗流特性和黏弹性的测定方法,并结合疏水缔合聚丙烯酰胺的结构特点,主要从宏观波及系数和微观驱油效率两方面,分析了影响其驱油能力的几种因素,包括有效黏度、黏弹性、界面黏度、水质因素和多孔介质中的临界缔合浓度。结果表明,将HAPAM用于聚合物驱还有一定的局限性。最后提出HAPAM在今后的发展应用中值得重视的一些问题。Application of hydrophobically associating polyacrylamide（HAPAM） in high temperature and high salinity reservoirs has become one of the hottest research areas of polymer flooding in recent years.In this paper,the measurement techniques on flow properties and viscoelasticities of HAPAM through porous media were described.Furthermore,according to the structure characteristics of HAPAM,some factors influencing oil-displacement capability were discussed from two respects,sweep efficiency and oil displacement efficiency,including the effective viscosity,viscoelasticity,interfacial viscosity,water quality and critical association concentration in porous media.The results showed that there were some limitations to use HAPAM as polymer flooding agent.Finally,some problems on the application and development of HAPAM,being worth to take seriously,were presented.
