NUMERICAL MODELING OF GAS HYDRATE FORMATION IN A POROUS COLLECTOR

This paper describes a mathematical model and features of gas hydrate formation during the injection of natural gas with a given composition into a porous reservoir containing the same gas and water in the initial state. Numerical solutions of the axisymmetric problem are constructed, which describe the distributions of the main parameters in the reservoir both with the frontal surface and with the volumetric region of phase transitions. The influence of the parameters of the injected gas and porous medium on the mode and rate of gas hydrate formation is investigated.
