摘　　要：极地天然气水合物资源潜力巨大,储层类型主要为富砂沉积物储层,最可能实现远景勘探和商业利用,是一种重要的战略能源。综述了天然气水合物在极地的分布情况、极地主要地区天然气水合物矿藏资源量以及水合物开发利用的资源金字塔。结合美国、加拿大和俄罗斯在北极冻土区天然气水合物勘探开发的案例进行了4种开采技术优缺点对比,并对极地区和非极地区5次天然气水合物试采效能进行对比评价。根据目前国际油气价格、能源结构、各国水合物研究目标和我国天然气水合物勘查开发现状等,提出了我国参与极地天然气水合物研究和开发的思路。A great amount of gas hydrates occurs in polar regions.They are dominated by the type of sand rich reservoir which is relatively easier to be put into exploration and commercial production.Therefore,gas hydrates in the polar region are regarded as a kind of important strategic energy sources of the world.In this paper,upon the distribution of gas hydrate,we made an assessment of gas hydrate resource,and reviewed the gas hydrate resource pyramid in the polar regions.Upon the information from the US,Canada and Russia on exploration and development of gas hydrate in the Arctic region,we made an introduction to and comparison of four kinds of extraction technology,and gas hydrate pilot production efficiency in polar and non-polar regions.According to the current international oil and gas prices,the energy structure of the world,research targets of gas hydrate in various countries and the current situation of gas hydrate exploration and development in China,we suggest China actively participating in the research and development of polar gas hydrate.
