中文摘要	this paper is intended to determine the appropriate conditions for replacing ch4 from ngh with co2. by analyzing the hydration equilibrium graphs and geotherms, the hszs of ngh and co2 hydrate, both in permafrost and under deep sea, were determined. based on the above analysis and experimental results, it is found that to replace ch4 from ngh with gaseous co2, the appropriate experimental condition should be in the area surrounded by four curves: the geotherm, (h-v)(co2), (l-v)(co2) and (h-v)(ch4), and to replace ch4 from ngh with liquid co2, the condition should be in the area surrounded by three curves: (l-v)(co2), (h-l)(co2) and (h-v)ch4. for conditions in other areas, either co2 can not form a hydrate or ch4 can release little from its hydrate, which are not desirable results.
