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
