摘　　要：为认识改性聚合物的耐温抗盐性能,提高聚合物在高温高盐油藏中的适用性,针对西达里亚三叠系高温高盐油藏条件,选用新型梳型聚合物KYPAM-6A和疏水缔合聚合物HAP进行研究。研究表明,HAP性能明显优于KYPAM-6A。HAP具有高效的增黏性和耐温抗盐性,长期热盐稳定性实验表明HAP在老化60 d后黏度保留率为97.7%,老化180 d后黏度为8.9 mPa.s,能够有效控制西达里亚油藏油水流度比,提高体积波及系数。In order to understand the temperature and salt resistance properties of the modified polymer and to improve the suitability of the polymer in the high-temperature and high-salinity reservoirs,this paper selects a new comb polymer KYPAM-6A and a hydrophobic associating polymer HAP to performance evaluation study.The study shows that the HAP performance significantly is better than KYPAM-6A.HAP has efficient viscosifying capacity and temperature and salt resistance.Long-term stability of the thermohaline experiments show the viscosity retention rate of HAP is 97.7% after aging 60 days,and the viscosity of HAP is 8.9mPa.s after aging 180 days,and this viscosity can effective control oil-water mobility ratio and improve sweep efficiency of the XiDaLiYa reservoir.
