In thi s 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 an alysis of this expression shows that this factor is equal
