摘　　要：通过不同水质抗盐聚合物污水配聚体系回注1000mD岩心的流动性实验,以渗透率损失率评价配聚体系对岩心的伤害程度,确定了其注入界限并通过驱油实验评价了驱油效果,研究结果对抗盐聚合物污水配聚回注的油层保护和提高采收率具有积极作用。This article designed aflowability experiment for the reinjection of 1000mD rock core with different water quality salt resistant polymer wastewater blending systems.The degree of damage caused by the blending system to the core was evaluated based on permeability loss rate,and its injection boundary was determined.The oil displacement effect was evaluated through oil displacement experiments.The research results showed that the oil layer protection and enhanced oil recovery of salt resistant polymer wastewater blending reinjection have a positive effect.
