| Abstract: | A macroscopic law of flow of a viscoplastic Schwedoff-Bingham fluid through a porous medium is obtained on the basis of percolation
theory with allowance for viscous and inertial losses. The asymptotics of the flow law are estimated and expressions for determining
the limiting pressure gradient as a function of the microinhomogeneity parameters are given. Satisfactory qualitative agreement
between the theoretical and known experimental data is observed.
