用改进后的沟槽式界面粘度仪测定方法系统地测量了不同聚合物 ,不同聚合物浓度 ,不同矿化度的聚合物溶液/模拟油体系在不同温度下的界面剪切粘度。实验结果表明 ,聚合物溶液 /模拟油的界面剪切粘度同时受温度、聚合物浓度及溶液矿化度的影响 ,且其变化规律与聚合物溶液的体相粘度的变化规律截然不同。通过分析 ,提出了表征界面流变性的另一参数—无因次界面粘度 ,它排除了因聚合物溶液体相粘度变化带来的界面粘度变化 ,并分析了温度、聚合物浓度和溶液矿化度对无因次界面粘度的影响规律。
The interfacial shear viscosity of polymer solution / pseudo-oil system with different polymers, different polymer concentrations and different salinities at different temperatures was systematically measured by a modified method of measuring the interfacial viscosity of the groove. The experimental results show that the interfacial shear viscosity of polymer / simulated oil is influenced by the temperature, polymer concentration and solution salinity at the same time, and its variation law is quite different from that of polymer solution. Through the analysis, another parameter that characterizes the rheology of the interface, the dimensionless interface viscosity, is proposed, which precludes the change of interface viscosity caused by the change of the bulk viscosity of the polymer solution. The temperature, polymer concentration and solution mineralization Influence of Degree on Viscosity at Uneven Interface.
