A mathematical model for the transport of solid particles of difference size by two-phase filtration flow is proposed. The phenomena of the reduction dynamic porosity and permeability with the deposition and blocking of the porous medium are described. The equation determining the change of the function of pore size distribution in time is obtained. Numerical results show that particle size distribution should be taken into account when suspension filtration is considered. Otherwise the temporal error can be large.
