天然气水合物(Gas Hydrates)是一种由气体和水形成的冰状白色固态晶体,常在一种特定的高压低温条件下形成并稳定存在,广泛发育在浅海底层沉积物和深海大陆斜坡沉积地层以及极地地区的永久冻土层中。现有研究表明,天然气水合物是一种未来的优质、洁净能源,其蕴藏量约是现有地球化石燃料(石油、天然气和煤)总碳量的2倍;它作为温室气体甲烷的最大载体,又可能是影响全球气候变化和引发海底地质灾害的重要因素。 2001年2月27日—3月1日在北京香山召开了主题为“天然气水合物研究现状及我国的对策”的香山科学会议第160次学术讨论会。会议执行主席是金翔龙院士和戴金星院士。
Gas Hydrates is a kind of ice-like white solid crystal formed by gas and water. It is often formed under a specific high-pressure and low-temperature condition and is stable. It is widely found in shallow marine sediments and deep-sea continental slope sedimentary formations As well as permafrost in polar regions. Existing research shows that natural gas hydrate is a future, high-quality, clean energy source with about 2 times the total carbon content of existing geo-fossil fuels (oil, natural gas and coal); it is the largest carrier of greenhouse gases methane It may also be an important factor affecting the global climate change and triggering seabed geological disasters. From February 27 to March 1, 2001, the 160th Symposium on Fragrant Hill Scientific Symposium was held in Fragrant Hills, Beijing, with the theme of “Status Quo of Natural Gas Hydrate Research and China’s Countermeasures”. The executive chairman of the meeting is academician Jin Xianglong and academician Dai Venus.
