| 摘 要： | 通过实验研究了冰点以下天然气水合物的生成反应中压力，温度及冰粒大小等因素的影响。并研究了过冷和过压在水合物生成中的作用。实验结果表明：压力越高，温度越低，冰粒越小，越有利于水合物的生成，并且过冷及过压程度和过压时间均促进水合物的生成，得出了衡量反应进行程度的天然气水合物含气率随反应进行时间的关系曲线。

| Abstract: | The influence of pressure, temperature and particle size of ice on the formation of natural gas hydrate below ice point was experimentally investigated, and the influence of supercooling and overpressure was also studied. The results show that the formation would be enhanced by increasing pressure, decreasing temperature and reducing the particle size of ice. It was also obtained that the supercooling or the overpressure degree and time could stimulate the formation of hydrate. The curve of the gas content in natural gas hydrate versus time was also obtained, which can be used to evaluate the reaction degree. |
