Abstract: A mathematical model is proposed to describe the substitution of carbon dioxide for methane in gas hydrate upon injection of liquid carbon dioxide into a porous medium initially saturated with methane and its hydrate. Self-similar solutions of the axisymmetric problems that describe the distribution of the main parameters of the bed are constructed. It is shown that there are solutions, according to which the process can occur both with and without boiling of carbon dioxide. Diagrams of the existence of each type of solution are constructed.

Keywords: porous medium, filtration, gas hydrate, substitution, carbon dioxide, boiling.
