摘　　要：我国油田已全面进入三次采油阶段,研制适应高温高盐开采环境下的驱油剂受到广泛关注。针对传统聚丙烯酰胺类驱油剂进行了改性,采用水溶液聚合的方法,制备并优化了丙烯酰胺/2-丙烯酰胺基-2-甲基-1-丙烷磺酸/对苯乙烯磺酸钠(AM/AMPS/SSS)三元共聚物,探究了各种反应条件对产物水溶液表观黏度的影响,总结分析了相关规律,得到最优的共聚物制备条件。使用旋转黏度计,对聚合物溶液的表观黏度、耐温耐盐性能进行了研究,最终得到了耐温、耐盐效果明显,热稳定性良好的AM/AMPS/SSS三元共聚物,在目前严峻的原油开采环境中有较好的应用前景。China’s oil fields have entered the stage of tertiary oil recovery.The development of oil displacement agents adapted to high temperature and high salt production environment has attracted extensive attention.In this paper,polyacrylamide,a traditional oil displacement agent,was modified,and acrylamide/2-acrylamyl-2-methyl-1-propane sulfonic acid/sodium p-styrene sulfonate(AM/AMPS/SSS)terpolymer was prepared and optimized using aqueous solution polymerization.The effects of various reaction conditions on the apparent viscosity of the product aqueous solution were explored,and the optimum preparation conditions of terpolymer were obtained.The apparent viscosity,heat and salt resistance of terpolymer solution were studied by using rotary viscosimeter.Finally,AM/AMPS/SSS terpolymer with obvious heat and salt resistance and good thermal stability was obtained,which has a good application prospect in the current severe crude oil exploitation environment.
