大多数专家都认为在 2 1世纪初期世界石油产量将达到高峰 ,之后开始下滑。一些国家和能源公司正在从长远考虑 ,寻找天然气水合物等非常规能源。自然界中的天然气水合物主要分布于北极周围的永冻区以及浅海大陆架沉积物中。蕴藏于海底的天然气水合物资源比估算的常规天然气储量 Most experts agree that world oil production will peak in the early 21st century and begin to decline thereafter. Some countries and energy companies are looking for long-term, unconventional energy sources such as gas hydrates. Natural gas hydrates are mainly found in permafrost around the Arctic and in shallow continental shelf sediments. Natural gas hydrate resources that are buried in the seabed are more likely to be estimated than conventional gas reserves
