The efficiency of using the indirect near-boundary element technique for the construction of numerical-analytical solution of the problem of unsettled motion of compressible fluid in porous, closed, piecewise homogeneous reservoir, including nonlinear behaviour of regions materials and ideal contact at the interface media, was proved. Series of computational experiments were carried out to assess the influence of characteristics of environment on reservoir pressure change.
