OF LIQUIDS ON THE PROCESS OF DISPLACEMENT IN A POROUS MEDIUM

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.
