摘要：At present, the optimization of the optimal thermal recovery temperature in the process of thermal natural gas hydrate is considered from the aspects of reducing the heat injection and increasing the heat of combustion of the gas, that is, the combustion of methane gas under the unit heat injection. The thermal recovery temperature corresponding to the maximum heat is the optimal thcnnal recovery temperature. Based on the consideration of reducing the heat loss in the thermal recovery process, this paper considers the reduction of the duration of the thennal recovery process, introduces the new concept of ther-mal recovery development efficiency, and defines the thermal recovery development efficiency as the unit heat injection in the natural gas hydrate thermal recovery process. The combustion heat of the average gas production rate is introduced into the concept of an infinitely long cylindrical heat exchange reaction kettle. Tlic 303K, 318K, 333K, 348K and 353K partition wall thennal gas hydrate experiments are carried out for the own equipment. The experimental data show that 348K °C can be obtained. The largest thennal development efficiency. Using the thermal development efficiency evaluation standard of this paper, for (he weather hydrate thennal recovery process under difTerent parameters, by detennining the optimal heat exchange temperature, the energy utilization efficiency and gas production rate of the thermal recovery process can be significantly improved, and the thermal recovery development can be reduced. Economic costs in natural gas hydrate processes.
