摘　　要：为研究瓦斯水合物生成与分解过程的温度分布及热量传递规律,利用可视化实验系统研究了两种体系甲烷水合物生成过程反应热和水合过程的温度分布。根据实验数据,结合反应热计算方程,计算两种实验体系的反应热,研究促进剂四氢呋喃(THF)的添加对甲烷水合反应体系温度场的影响。结果表明,THF的添加,导致甲烷水合物的生成量增多,对应的反应热增多,提高了水合反应体系的温度以及温度的上升速率。Aimed at the temperature distribution and heat transfer law of formation and decomposition of gas hydrate, the heat of reaction and the temperature field of methane hydration process of two systems methane hydrate formation were studied using visual experimental system. The reaction heat of the two systems were calculated combined with the reaction heat equations based on experimental data, the influences of the addition of tetrahydrofuran （THF） on the tem- perature field of methane hydration reaction system were studied. The results show that the addition of THF leading to the generation of methane hydrate increases and the quantity of corresponding reaction heat increases, thereby improves the temperature of hydration reaction system and the rising rate of temperature.
