As experience shows the development of deep oil fields with terrigenous reservoirs along with irreversibility of deformation there is a loss of stability of the formation's skeleton, i.e. he collapses in zones of strong pressure decrease. Particles of rock then are carried out from the formation by a flow of liquid. In this case, the composition of the liquid changes, a two-phase medium consisting of a liquid and a solid particles. In this paper we propose generalized dependencies of the variation porosity and permeability in the elastic-plastic mode of filtration The liquid taking into account the removal of the destroyed particles from the formation, where it is taken into account non-local character of the removal of the destroyed particles in time.
