【 摘 要 】

A system of nonlinear differential equations is proposed for describing the process of the gas hydrate formation during the injection of methane into a porous reservoir of finite length. This reservoir initially saturated with methane and ice. The case of phase transformations "ice + gas → gas hydrate" occurring in an extended region is considered. It has been established that over time the extended region of hydrate formation degenerates into a frontal surface. It is shown that at low pressures of the injected gas it is possible to stop the phase transition boundary.
