The steady regimes of filtration of gas in a porous medium are investigated at dissociation and formation of gas hydrates. One-dimensional (flat, radial and spherical) problem for nonisothermal filtration of gas or gas liquid mixture in a porous medium containing gas hydrates is considered, at weak pressure or temperature variations on boundary. The solutions with two fronts of a discontinuity of hydrate saturation and with volumetric dissociation of a hydrate are obtained.
