摘　　要：进行了不同条件下聚丙烯酰胺和梳形抗盐聚合物溶液的粘度及流变性测定,发现根据不同条件下聚合物溶液的流变参数可以定性地判断三次采油用聚合物的抗盐能力大小和趋势。聚合物的流变性分析可作为评价聚合物抗盐性能的一条新途径,具有一定的实用价值。The polyacrylamide(PAM) and the KYPAM polymer solution viscosity and rheology were measured under different conditions. The results show that the anti-salt performance of the KYPAM polymer is much better than polyacrylamide. The n value of KYPAM is smaller than that of PAM in salt aqueous solution. The difference of the n value between PAM and KYPAM polymer increases when the salinity of water increases. Viscosity measurements show that the anti-salt character of KYPAM polymer is more pronounced with the increase of water salinity. For the polymers used in enhanced oil recovery(EOR), the results show that the anti-salt abilities and tendencies of the polymers can be evaluated qualitatively by measuring rheological parameters of the polymer solution under the different conditions. The rheological measurements of the polymer can be an efficient method for evaluation of anti-salt characteristic of polymers.
