SIMULATION OF THE INJECTION OF LIQUID CARBON DIOXIDE INTO A GAS-HYDRATE STRATUM OF FINITE EXTENT

Results of numerical investigation of the injection of liquid carbon dioxide into a porous stratum saturated with methane and its gas hydrate, accompanied by the replacement of methane in the methane gas hydrate by carbon dioxide, are presented. A round stratum with an impermeable outer boundary of fi nite radius was considered. It was established that, depending on the duration of the injection of liquid carbon dioxide into such a stratum, the replacement of methane in the methane gas hydrate by carbon dioxide can proceed with the boiling of carbon dioxide or without it
