天然气水合物（NGH）是天然气与水在低温高压条件下形成的笼形物，亦称可燃冰。本文根据天然气水合物的生成机制，在实验室模拟天然气水合物的生成环境。实验主要通过将95％的水与5％的纳米SiO：制成泡沫，并在1．3℃条件下，将纯度为99．9999％的天然气充人到装有泡沫的密闭反应釜中，观察反应釜中压力的变化情况，并探究不同的充气压力对储气密度的影响。%Natural gas hydrate （NGH）, known as flammable ice, was a clathrate compound formed by natural gas and water under conditions of low temperature and high pressure. According to the formation mechanism of natural gas hydrate, the formation environment of natural gas hydrate in laboratory was simulated. The experiment was about that 95 % of the water and 5% of nano SiO2 make into foam, and in 1.0 conditions, the purity of 99. 9999% of natural gas would be inflated to the airtight reaction kettle with the foam, the changes of pressure in the reaction kettle was observed, and the different inflation pressure to the influence of gas storgage density was explored.
