| 摘 要： | 我国是世界上既有海域水合物也有陆域水合物的少数几个国家之一。中国地质调查局高度重视陆域水合物调查研究,2016年正式设立“陆域天然气水合物资源勘查与试采工程”,通过对我国重点冻土区开展地质、地球物理和钻探调查,研发有效的陆域水合物调查、钻探和资源评价技术,初步摸清资源家底,评价资源潜力。自2002年开始探索性调查以来,已在青海省发现木里天然气水合物产地1处、昆仑山垭口盆地和乌丽地区疑似产地2处及系列找矿线索,评价出南祁连盆地、羌塘盆地及漠河盆地三大成矿远景区、12个成矿区带,资源潜力巨大; 在祁连山木里地区成功实施单直井和水平对接井试采,并取得了陆域天然气水合物成矿理论、勘采技术、环境调查和平台建设系列成果。以上成果有力推进了我国天然气水合物资源勘查试采进程,支撑国务院将天然气水合物设为第173个新矿种,初步形成“海陆并举、资环并重”的良好局面。

| 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. |
