Gas extraction from porous medium containing hydrates by means of depression influence

The decomposition of gas hydrates partially sating a porous medium by means of depression influence is investigated in the plane one-dimensional and radial automodel formulations. It is shown that, depending on the state of the porous medium and boundary pressure, the gas can be extracted from a hydrate-containing stratum in three modes, with qualitatively differing structures of the formed zones. The criteria distinguishing these modes are revealed.
