摘要：
A mathematical model is presented and numerical solutions have been constructed for the problem on injecting liquid carbon dioxide into a bed consisting of a skeleton, methane hydrate, and pores filled with methane. It is assumed that the process has two stages. At the first, short stage, displacement of the free gas from the pores takes place. At the second, longer stage, replacement of methane by carbon dioxide in the hydrate state and its dissolution occur. The flow rates of carbon dioxide and methane, as well as their mass in the considered period of time have been considered. © 2017, Springer Science+Business Media, LLC, part of Springer Nature.
