Abstract The linearity of Darcy's law is known to be disturbed at both high and low flow velocities [1–3]. In the first case, this is associated with the increase in the inertial component of the hydraulic losses in the presence of large pressure gradients. The effect was theoretically investigated, for example, in [4]. In the second case, the nonlinearity is associated with the interphase interaction of the fluids and the skeleton of the porous material on the contact surface [5]. Here, within the context of the percolation approach [6, 7], the behavior of the phase permeabilities is analyzed for low flow velocities, when on the microlevel (flow in an individual pore channel) the fluids display plasticity properties [8].
