The periodic hydrodynamic perturbation evolution in porous media is considered under nonequilibrium liquid filtration. The temporal model parameters contribution in relaxation has determined. The pressure amplitude extremums existence have established in borders of various hydroconductivity zones passing through the obser-vation point.
