【 摘 要 】

The paper presents a mathematical model of dissociation of methane hydrate during thermal exposure to a porous layer. The problem of the impact of a heat source (hot fluid) on a porous reservoir of finite length, initially saturated with methane hydrate, is considered. The temperature distributions in the system are constructed at different points in time. The influence of the temperature of the heat source on the nature of the movement of the phase transition boundary is investigated.
