INFLUENCE OF DIFFERENCE IN SPECIFIC ELECTRICAL CONDUCTIVITIES OF LIQUIDS ON THE PROCESS OF DISPLACEMENT IN A POROUS MEDIUM
R. R. Mirzadzhanov UDC 622.276 The results of experimental investigation of the influence of the specific electrical conductivity of liquids on the process of displacement in a porous medium have been given. It has been established that, for cofiltered aqueous electrolyte solutions of virtually the same viscosity, an increase in the ratio of the electrical conductivities of the displacing and displaced liquids leads to a decrease in the displacement coefficient before the breakthrough of the displacing liquid. It has been found that, in displacement of a nonpolar liquid by aqueous systems close in viscosity, an increase in the specific electrical conductivity of the displacing liquid causes a reduction in the displacement efficiency.
