At present, the description of non-steady state flow of immiscible fluids is carried out using equilibrium phase permeabilities and a capillary pressure curve. The mentioned functions are determined by the saturation of porous media with any of the phases and do not depend on time and space coordinates. In this case the phase permeabilities are determined by the results of laboratory experiments on steady state two-phase flow, and the Leverett’s function is found from the porometric curve.
