中国天然气资源研究

Chinese natural gas resources

中国天然气资源十分丰富,天然气远景资源量为47 万亿m3,最终可采天然气储量14 万亿m3。天然气资源量主要分布于鄂尔多斯、塔里木、四川、柴达木、东海、莺歌海、琼东南、松辽、珠江口、渤海湾、准噶尔等11 个盆地中。西部地区的资源量约占总量的80%左右;东部占8%;海域占12%。中国天然气资源的勘探程度仍然很低,勘探潜力大,勘探领域多,中国陆上主要天然气勘探领域以四川、鄂尔多斯、塔里木、柴达木四大气区和松辽深层为主;海上以东海、莺歌海、琼东南以及珠江口盆地为主。中国煤层气资源也较丰富,煤层气远景资源量为27.3万亿m3。

China is rich in natural gas resources and the prospective reserves and producible reserves are up to 47 × 1012 m3 and 14 × 1012m3, respectively. The gas resources distribute mainly in 11 basins as Ordos, Tarim, Sichuan, Qaidam, East China Sea, Ying-Qiong, Songliao, Zhujiangkou, Bohai Bay, and Junggar Basin, etc. The resources in west, east China and sea area are about 80%, 8% and 12%, respectively. The gas resources could be divided into 5 types based on their reservoir types: conventional gas, low permeability gas, extremely low permeability gas, carbonate fracture gas and carbonate porosity gas. The gas exploring realms are mainly in Sichuan, Ordos, Tarim, Qaidam and deep layer of Songliao Basin on land and in Eastern China Sea, Ying-Qiong and Zhujiangkou Basin on Ocean. China is also rich in coal bed methane resources. Its prospective reserves are 27.3 × 1012m3.
