摘　　要： 在标准状况下 1m3的水合物可包容 15 0～ 180m3的天然气 ,其巨大的储气能力和相对“温和”的储气条件为天然气储运展现了很好的前景。介绍了水合物储存天然气的实验装置 ,并对合成天然气 (甲烷、乙烷、丙烷的体积百分比分别为 91.47%、4.94%、3 .0 9% )的水合物形成过程进行了初步的实验研究 ,获得了水合物形成过程的耗气速度、储气密度与水合物形成条件 (压力、温度 )的关系。在压力为 3 .79MPa ,温度为 2 73 .95K的试验条件下 ,单位体积的水合物可储存约 145体积的天然气 (标准状况下 ) ,水合物填充率达到理想填充率的 81%。 m 3 of natural gas may be contained in 1 m 3 of hydrate at standard conditions,which opens up a vast range of prospects for storing and transporting natural gas because of the large storage capacity and gentle storage condition of hydrate.On the basis of designing the experimental rig of storing natural gas in hydrate,a primal experimental investigation on the synthetic natural gas (being composed of 91.4 percent methane,4.94 percent ethane and 3.09 percent propane)hydrate forming process was carried out,thus determining the relation between the gas-consumption speed and storage capacity in hydrate forming process and the hydrate formation conditions (pressure and temperature).At the conditions of 7.79 MPa pressure and 273.95 K temperature,about 145 volumes of natural gas (at standard conditions) may be stored in 1 volume of hydrate and the filling rate of hydrate may be up to 81%.This result investigated is advantageous to the popularization and application of the technique of natural gas' being stored in hydrate.
