摘　　要：应用界面粘弹性测定仪和界面张力仪,测定了碱、表面活性剂和聚合物三元复合驱油体系的油/水界面剪切粘度和界面张力。实验表明,在一般情况下,碱和表面活性剂的降低界面张力作用与提高界面剪切粘度作用相对应。聚合物HPAM大多数情况下都使界面张力略有升高。且可使极低的界面剪切粘度升高,很高的界面剪切粘度降低。Interfacial shear viscosity （ISV） and interracial tension （IFT） were measured at 45℃ for systems of crude oil and various chemical （alkaline,surfactant and polymer） flooding solution. It is concluded that.Generally,for both alkaline and surfactant,when they alone or together were added into the solution,the action of reducing the IFT corresponds with the actions of increasing the ISV will be produced. In the great majority of cases,addition of polymer （HPAM） will cause an insignificant rise in the IFT. When the ISV was extremely low, addition of HPAM will cause the ISV to increase. On the other hand, when the ISV was extremely high the HPAM will cause it to decrease.
