| Abstract: |
| The interfacial tension and interfacial shear viscosity of polymer solution/asphaltene model oil were measured respectively by Wilhelmy method and biconical bob method. The influence of polymer concentration on the interfacial shear viscosity was studied. The results sliuw that the interfacial tension of polymer solulion/asphaltene model oil increases because of the existence of polymer. But the adsorption of asphaltene at interface is affected because of the existence of polymer，which results in the intension declining of asphaltene interfacial structure. When the polymer concentration is lower，the interfacial shear viscosity of polymer solution/asphaltene model oil is leaa than that of sliniulalion water/asphaJtene model oil. When the polymer concentration is higher, the interfacial shear viscosity of polymer solution/asphaltene model oil is more than that of stimulation water/asphaltene model oil. |
