Abstract：China is one of the few countries in the world that have both marine and permafrost hydrates. China Geological Survey attaches great importance to the investigation and research of natural gas hydrate in permafrost areas, and officially established the project of Exploration and Test Production of Natural Gas Hydrate Resources in permafrost in 2016. It aims to realize the strategic new discovery of hydrate in permafrost regions as soon as possible and evaluate the resource potential, by carrying out geological, geophysical and drilling investigations in key permafrost regions in China, and to develop effective investigation, drilling and resource evaluation techniques for natural gas hydrate in permafrost regions. Since the beginning of the explorative survey of natural gas hydrate in permafrost in 2002, Muli natural gas hydrate producing area has been found in Qinghai, 2 suspected places have been found in Yakou Basin of Kunlun Mountains and Wuli area, with a series of prospecting clues and 12 potential hydrate belts with great resource potential have been evaluated in three metallogenic prospective areas of South Qilian Basin, Qiangtang Basin and Mohe Basin. The first single vertical well test in China and the first horizontal butt well test in the world were successfully carried out in Muli area of Qilian Mountains, and a series of achievements were obtained in gas hydrate formation, prospecting technology, environmental survey and platform construction. These achievements strongly promote the process of natural gas hydrate resources exploration test, and provide powerful support in State Council setting natural gas hydrate as the 173rd new mineral, initially forming a good situation of both land and sea investment and environmental protection.
