Factors influencing mobility control by polymer solution
The flow of solutions of various polymers is examined with respect to the rheological properties of the solutions and the interaction of the polymers with porous media. The mobility of some polymer solutions in porous media can be predicted reasonably well from a knowledge of the viscosity behavior, while the mobility of other polymer solutions is lower than that predicted from viscosity alone. Certain viscoelastic polymer solutions owe their decreased mobility at low flow rates in part to the reduction of the permeability of a porous medium by the retention of a very small amount of the polymer in the porous matrix. This reduction in permeability does not correlate with gross chemical adsorption. The mechanism of permeability reduction appears to be mechanical in nature, but simple plugging of the smaller pores does not adequately explain the observed effects. (23 refs.)
