MATHEMATICAL MODELLING OF GAS RECOVERY FROM GAS-GASHYDRATE STRATUM AT THREE-PHASE GAS-GASHYDRATE-WATER EQUILIBRIUM
The mathematical model of the gas-gashydrate stratum waterless mining is considered at the threephase gashydrate-gas-water equilibrium. The liberated gas relative proportion in the overall gas production, the gas recovery factor from the gas-gashydrate stratum, the liberated gas recovery factor from the gashydrate crystal were determined within this model. The task was solved by means of balance and numerical methods. The convergence of results proved to be good.
