| Summary: | Abstract The paper presents a mathematical model of dissociation of methane hydrate under thermal influence on a porous layer. The problem of influence of a heat source (hot liquid) on a porous layer of finite length initially saturated with methane hydrate is considered. Temperature distributions in the system at different times are constructed. The influence of the heat source temperature on the character of the phase transition boundary motion is investigated. A technological scheme is proposed, and on its basis a mathematical model is constructed that describes heating and simultaneous gas extraction into a combined well consisting of two coaxial pipes. The efficiency of the proposed method of gas production is analyzed. |
