进入21世纪,能源危机越来越紧迫,寻找新的可代替传统石油和天然气的能源已经刻不容缓。最近,天然气水合物被誉为21世纪人类可持续发展的战略接替能源。 天然气水合物是在特定的高压低温条件下,天然气与水结合生成的一种外观似冰的白色结晶固体。但它与冰的性质不同,对温度没有过多要求,也被称为甲烷水合物。 天然气水合物主要存在于地球表层圈层中,赋存区域以大洋边缘海区的洋底沉积物中为主,也产于大陆极地永久
In the 21st century, the energy crisis is getting more and more urgent. It is urgent to find a new energy source that can replace traditional oil and gas. Recently, gas hydrates have been hailed as strategic alternative sources of human sustainable development in the 21st century. Natural gas hydrate is an ice-like, white, crystalline solid formed by the combination of natural gas and water under specific high-pressure and low-temperature conditions. But it is different from the nature of ice, the temperature is not excessive requirements, also known as methane hydrate. Natural gas hydrates are mainly found in the surface layer of the Earth, and are mainly dominated by sediments in the ocean floor at the oceanic margin. They are also produced in the polar regions of the Earth permanently
