摘　　要：煤层气(瓦斯)的储存和运输是实现煤层气能源利用的重要前提,水合物法是将来煤层气等气体固化储运的主要技术之一。煤层气水合固化储运过程受热量传递的控制,而开展瓦斯水合物的热量传递机理研究,其导热系数是必须要知道的热物性参数。基于瞬态热线法原理,建立了一套测试设备对瓦斯水合物的导热系数进行了实验研究,获得该瓦斯水合物样品导热系数及其和温度的关系。从瓦斯水合物的热物性因素方面支持了以NGH(水合物储运)形式对瓦斯进行水合固化储运的可行性。Storage and transportation of coal bed methane （gas） is an important prerequisite for gas energy use, In the future, the hydrate technique is one of the chief technologies of gas storage and transportation. The storage and transportation of gas hydration is controlled by heat transfer, and carry out the study of gas hydrate heat transfer mechanism, We must know the thermal conductivity of the gas hydrate . A test equipment has been constructed to measure thermal conductivity of gas hydrate. The thermal conductivity of the gas hydrate and the relationship between it and the temperature are obtained. From the aspects of thermal factors of gas hydrate is supported that the feasibility of gas storage and transportation with NGH（ natural gas hydrate）.
