摘要: 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。

Abstract: A modified deep-channel viscous traction interfacial vis-
cometer was applied to measure the interfacial shear viscosity for
HPAM/oil system. A dimensionless interfacial shear viscosity
was proposed to exclude the effect of bulk viscosity changes of
polymer solution on the interfacial viscosity. In this study, the
factors influencing the viscosity involved in Polymer and its con-
centration, temperature, and TDS in the polymer solution. Ex-
perimental results indicated that the interfacial viscosity for the
HPAM/oil system is quite different from the bulk viscosity for
HPAM solution.

Key words: interfacial shear viscosity, interfacial rheolo-gy, polymer flooding, improved oil recovery
