摘　　要：为改善江苏油田聚合物驱的增油效果,针对其高温、高矿化度和断块油藏地质流体特点,通过室内实验对聚合物溶液增粘性、稳定性、耐温性、抗盐性、抗剪切性、滞留特性和流变特性等技术指标进行检测,并利用模糊综合评判方法对检测结果进行评判。结果表明,模糊综合评判方法可以实现对多因素影响下不同品质聚合物溶液性质优劣的定量评价,为合理选择聚合物提供了新的方法。In order to improve polymer flooding in Jiangsu Oilfield, laboratory experiments have been conducted to measure the viscosifying capacity, stability, temperature tolerance, salt resistancy, shearing resistance, retention property, and rheological property of polymer solution in accordance with the characteristics of high temperature, high salinity and reservoir fluids in fault block reservoirs. Fuzzy comprehensive evaluation method has been used to judge experiment results. The result indicates that fuzzy comprehensive evaluation method can evaluate the quality of different polymers under different conditions, thus providing a new method for choosing polymer.
