description The formation of gas hydrates during gas injection into a porous medium partially saturated with water is studied in a planar one-dimensional selfsimil ar formulation. The influence of the initial parameters of the porous medium (porosity, permeability, and moisture content), the temperature of the injected gas, and the intensity of the injection on the pattern of the hydrodynamic and temperature fields in the porous medium is analyzed. It is shown that depending on the intensity of the injection of a cold gas into the moist porous medium, the process can occur in several modes with qualitatively different structures of the zones of hydrate formation. Because of the formation of gas hydrates in volumetric regions, the heating of the porous medium by tens of degrees can occur during the injection of the cold gas; thus, the process of hydrate formation can serve as a certain means for increasing the temperature.
