摘　　要：日本通过制订国家层面天然气水合物研发计划,对天然气水合物研发进行统一部署,以水合物资源开发利用为目标,在日本周边海域开展了长期而广泛的天然气水合物调查研究,获得了大量天然气水合物存在证据.特别是在南海海槽东部集中开展了天然气水合物勘探开发研究,优选了一批水合物富集区,开展了两次水合物试采研究.在日本海东部边缘的初步调查发现了众多水合物有利构造,证实该海域也存在较好水合物资源潜力.日本还积极参与国际水合物开发合作研究与国内水合物开发模拟研究,为南海海槽水合物降压试采研究提供人员与技术支撑.日本在天然气水合物勘探开发研究的组织管理、研究策略等方面的做法与经验,对中国天然气水合物勘探开发研究具有一定的启示意义.Japan has long been attaching great importance to the resource value of natural gas hydrate on the country’s level, and gas hydrate exploration researches have been conducted all over the offshore Japan, dominantly by means of seismic survey, drilling and well logging, with Nankai Trough as a focus research area, and lots of evidences have been obtained indicating the existence of gas hydrate. The main hydrate exploration breakthrough offshore Japan lies in the selection of a number of gas hydrate accumulation zones in the eastern Nankai Trough, and the determination the target hydrate reservoir for production test. Another important achievement in gas hydrate exploration offshore Japan is the recent discovery of large amounts of structures favorable for the formation of gas hydrate in the eastern margin of Japan Sea, verifying that this area also has good hydrate potential. In the aspect of gas hydrate production research, Japan has long been focusing on the development, the verification and the improvement of hydrate production techniques, through international cooperation and domestic production modeling and simulations, which provides personnel and technical supports for the depressurization production test of the gas hydrate reservoir in Nankai Trough. Japan’s effective organization and management, and the research strategies of the gas hydrate may provide a certain significant implication for China.
