Abstract
In this paper we investigate theoretically the possibility to describe foam flow through porous media based upon the usual equations for two phase flow of immcisible fluids through porous media. We found class of solutions which can describe the main features of foam flow during gas mobility reduction (gas-blocking regime). An expression for the "gas mobility reduction factor" has been derived from the current consideration. The analysis of this expression shows that this factor is equal to (liquid mobility without foam)/(gas mobility without foam) at liquid saturation very closed to the irreducible one. A method for calculating of the gas mobility reduction factor is proposed .
