Abstract: Ninety-seven percent of natural gas hydrates reserves is distributed offshore, mainly in the deepwater areas. As for this potential new energy, the technological powers worldwide have launched the related research and test production projects. China successfully carried out test production of natural gas hydrates in the offshore areas of the South China Sea twice in 2017 and 2020, hitting a world record high both in total gas production and daily gas production. Japan also carried out test production of offshore natural gas hydrates twice. Based on the survey and test production of natural gas hydrates resources, this paper points out that the key influential factors of industrialization include test production process technology and industrial policies. The efforts should be focused on acceleration of the deepwater muddy silt mineral resources evaluation and production technological research and development, stimulating localization of deepwater drilling and gas production equipment. It is proposed that the government, enterprise and industry should step up collaboration to accelerate China’s offshore natural gas hydrates industrialization process.

摘要： 天然气水合物97%的资源量分布在海洋，且主要在深海区。作为一种潜在的新能源，世界科技大国竞相开展相关研究攻关和现场试采试验。我国于2017年和2020年两次在南海海域成功实施天然气水合物试采，创造了产气总量最大、日均产气最高的两项世界纪录。日本也开展了两次海域天然气水合物试采。基于我国海域天然气水合物资源勘查和试采现状，指出产业化关键影响因素包括试采工艺技术、产业政策等。应着力加快深海泥质粉砂矿体的资源评价和开采技术研发，带动深海钻探及采气装备制造国产化，建议政府、企业、产业加强协作，加快推进我国海域天然气水合物产业化进程。
