Abstract: The paper considers the problem of injecting gas into the porous layer initially saturated with gas and water, accompanied by formation of hydrate. We have investigated case where the intensity of hydrate is limited by diffusion of water through the hydrate layer formed between water and gas in the core of the pore of the channel. As part of this scheme kinetics of hydrate is determined one empirical parameter $D$ having the dimension of the diffusion coefficient (m$^2$/s). We have analyzed effect of the value of this parameter on the features of the process of hydrate formation, depending on the parameters that define the initial state of porous reservoir and reservoir characteristics.

Keywords: porous media, filtration, gas hydrate, diffusion, formation of hydrate.
