摘　　要：甲烷水合物是具有发展前景的新能源,其开采方法是当今世界的热门话题。运用实验探究甲烷水合物的合成、利用软件模拟结合实验等综合方法研究了甲烷水合物被热力开采时的注热温度、注热时间、注热速率,探究这些因素对其开采效果的影响。并结合构建物理模型和数值分析等方法分析了注热开采的动态及规律。结论表明,甲烷水合物的注热开采是一个非稳态的传热过程,温度与时间的关系先呈指数递减后呈线性递减。Methane hydrate is a new energy source with promising development,and its mining method is a hot topic in the world today.The effects of heat injection temperature,heat injection time and heat injection rate on the mining effect of methane hydrate during thermal exploitation were studied by means of experiments to explore the synthesis of methane hydrate and the combination of software simulation and experiments.Combined with the construction of physical model and numerical analysis,the dynamic and law of heat injection mining were studied.Conclusions show that the injection of methane hydrate is an unsteady heat transfer process,the relationship between temperature and time decreases exponentially and then linearly.
