中文摘要：
在定容的条件下,实验研究了甲烷水合物在不同的多孔介质中的生成特性,所使用的多孔介质平均孔径为9.03,12.95,17.96与33.20 nm,其中孔径为12.95 nm的多孔介质使用了三个粒径范围,分别为0.105～0.150 mm,0.150～0.200 mm,0.300～0.450 mm;其他孔径的多孔介质的粒径范围为0.105～0.150 mm.实验的温度范围为274.15～278.15 K,初始生成压力范围为7.4～11.0 MPa.实验表明,水合物的生成速度随着初始生成压力的升高与水浴温度的降低而增大,随着多孔介质粒径的增大与孔径的减小而降低.
英文摘要：
The formation behaviors of methane hydrate in the porous media were studied.The silica gel with the mean pore diameters of 9.03,12.95,17.96 and 33.20 nm and three particle diameters of 0.105～0.150 mm,0.150～0.200 mm and 0.300～0.450 mm was used as the porous media for the experiments,re-spectively.The formation experiments of methane hydrate in the porous media were carried out at the tem-perature range of 274.15～278.15 K and the initial formation pressure range of 7.4～11.0 MPa.The experi-ment results indicated that the formation rate of methane hydrate increases with the increase of the initial formation pressure,the decrease of the bath temperature,the decrease of the particle range and the increase of the mean pore diameter.
