据日本经济产业省透露 ,开采天然气水合物的实验已获成功 ,并将在今后 1 0年开发实用技术 ,用于近海海底天然气水合物的开采。试验在加拿大西北部进行。一口深 1 2 0 0米的井钻到天然气水合物层 ,通过井注入温水后 ,天然气水合物中的甲烷便溶在温水中 ,然后 ,把溶有甲烷的温水 According to Japan’s Ministry of Economy, Trade and Industry, the successful exploration of natural gas hydrate has been completed and practical technologies will be developed in the next 10 years for the exploitation of offshore gas hydrate in offshore areas. The test was conducted in northwestern Canada. A deep 1220 meters deep well drilled into the gas hydrate layer. After injection of warm water through the well, the methane in the gas hydrate was dissolved in warm water and then the methane-laden warm water
