天然气水合物导热系数的研究对于模拟自然界天然气水合物的成藏和天然气水合物勘探、开采具有重要意义。本文介绍了获取天然气水合物导热系数的实验测试和模拟计算方法，分析了气体水合物导热特性、导热机理以及水合物复合体系导热。总结了水合物导热规律，即外界温压条件和晶穴占有率对水合物的导热产生影响，且水合物的导热具有相似的温度压力依赖关系，并呈玻璃体的导热特性。水合物玻璃体导热特性由水合物笼型结构决定，而客体分子的存在强化了水合物导热的玻璃体属性。指出非稳态下天然气水合物导热性能变化研究对分析天然气水合物在常压下的稳定性、确定甲烷水合物等最佳储存温度、从导热角度探讨自保护效应机理等具有重要意义。

The study on gas hydrate thermal conductivity is significant for the gas hydrate reservoirs, exploration and mining. Experimental and measuring technique and modeling method for the gas hydrate thermal conductivity are presented. Thermal conduction features and mechanisms for gas hydrate, as well as thermal conductivity of complex system are reviewed. The thermal conductivity laws of gas hydrate are summarized. The outside thermobaric condition and cage occupancy effect on the gas hydrate heat performance. The thermal conduction of these gas hydrates, with gassy behavior, has similar temperature dependence. The gassy property of the thermal conduction is determined by framework of cage and reinforced by the guest molecules enclosed in the cages. It is figured out that studies on gas hydrates in unsteady-state with thermal properties that vary as a function of time are important. It is benefit to reveal gas hydrate stability under atmospheric conditions, to identify optimal storage temperature, and to discuss mechanism of self-preservation in the light of thermal conduction.
