摘　　要：考察温度、盐度等因素对优选NPLS凝胶颗粒体系的影响,评价聚合物复合NPLS凝胶颗粒体系的调驱效果。实验表明:随着温度的增加,NPLS凝胶颗粒体系的膨胀倍数增加;随着盐度的增加,体系的膨胀倍数减小;在长填砂管物模调驱实验中,聚合物复合NPLS凝胶颗粒体系具有良好的注入性。The NPLS gel particles system,which is steady and economic has been selected after a lot of experiments.Through temperature and salinity,the paper studies the impact on systems and evaluates displacement and profile control effect of the polymer solution which carries NPLS gel particle system.The experimental result indicates that： When the temperature rises,the expanding multiple of the NPLS gel particles will become bigger;When the salinity increases,the expanding multiple of the system becomes small;At long sand pack physical analog experiment,the polymer solution which carries NPLS gel particle system has a good injectivity and displacement and profile control effect;the oil recovery increases;the system has a good erosion.

关 键 词：调驱 膨胀倍数 采收率 注入性
