Abstract

Considered the problem of gas hydrate formation during injection of cold gas in the snow massif, initially saturated with the same gas. In work some limited scheme according to which, intensity of hydrate formation is limited by diffusion of gas through the hydrate layer formed between the phases of gas and ice, to the boundary of contact ice-hydrate, and is determined by the introduction of only one parameter the given diffusion coefficient. Shows the distributions of pressure, temperature, hydrate saturation and the saturation of the snow at different points in time. Held influence analysis of the effect of the pressure of the injected gas and the permeability of the snow massif on the intensity of hydrate formation.
