Abstract:

Experimental studies of the flow properties of polymer solutions in porous media by former investigators are reviewed in this paper. They suggested that polymer solutions exhibit dilatant behaviors at higher rates. However, the contribution of FRr and to resistance factors (FR) has not been evaluated. Based on the FR-V and FRr-V correlation data that were obtained from the flow tests performed by the authors, has been calculated, and the contributions of FRr and to the resistance factor have been compared. It is suggested that polymer solutions of high salinity exhibit dilatant behavior at high velocities, while those of low salinity probably exhibit pseudo-plastic. The higher the salinity of the solution, the higher the effective viscosity.
