Abstract: The paper deals with the process of injecting liquid carbon dioxide into a hydrate reservoir. It is shown that the process of methane replacement in a hydrate reservoir by injecting liquid carbon dioxide into it can consist of the following steps: piston displacement of free gas from the pores; replacement of methane with liquid carbon dioxide, its dissolution and leaching from the formation; completion of hydrate formation and leaching of the remaining methane gas from the hydrate reservoir. We have presented the distributions of pressure, density, hydrate saturation and temperature at different times.

Keywords: methane hydrate, carbon dioxide hydrate, methane substitution.
