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.
