RECENT STATUS OF MARINE GAS HYDRATE EXPLORATION AND PRODUCTION
-
摘要: 海底水合物是一种重要的新型能源矿产,曾认为在未来20~30年内不具开采价值,但是现在这种看法已经改变,美国和日本政府现正筹划进行试验性开采。近年科技界已经研究出适合于从深海水合物中开采甲烷气体的工艺技术和方法。目前,降压法已被证明是一种较为经济有效的方法。引述了日本天然气水合物勘探和开采纲要MH21,详细说明其开采试验的计划和设计。Abstract: Marine gas hydrate, which had been considered non-commercial for almost 20~30 years, is proved an important new energy source. The methodology and technology for extraction of methane from deep sea gas hydrate have been solved recently. The US and Japan have made plans to initiate testing production of methane from gas hydrates. The method of depressurization is proven more economic and effective. In this article, we try to make an introduction to the Japanese "Gas hydrate exploration and production program MH21". In addition to the detailed description of the plan, the design of production testing is also discussed in details.
