摘　　要：研究了一定矿化度下，不同分子量、不同水解度的聚丙烯酰胺对石油磺酸盐／正丁醇混合胶束体系的流型、粘度等流变性质的影响。The effect of polyacrylamide on rheology of petroleum stilfonate-butanol mixedmicelle system has been studied.The results showed that the mixed micelle svstem waspseudoplastic fluid with a yield point,and had a shear thinning property in the presence of7000ppm mineralized water.When polyacrylamide was added,the apparent viscosity ofmixed system further increased, without change of flow pattem. These systems were ana-lyzed by using the power-law and Casson models. This particular behavior is attributed tothe formation of polymer-micelle aggregates in the presence of mineralized water。
