摘要：

我国陆上天然气资源十分丰富,主要分布在中、西部分别占40%和36%,集中在石炭、奥陶、二叠、三叠及第三系,以油型气和煤型气为主分别占70%和29%.天然气的埋深范围较宽,集中在2000m以下的深度;在条件较差的黄土塬、山地和沙漠区集中了80.98%的天然气资源,依据勘探的难易程度、地质条件的优劣和认识程度的深浅,将陆上天然气资源分为Ⅰ、Ⅱ、Ⅲ类,其中Ⅰ类主要分布在东部的松辽盆地中央坳陷和渤海湾盆地5个富烃坳陷的第三系;中部的四川盆地川东和川中,鄂尔多斯盆地的中、东部和伊盟;西部的塔里木盆地轮台凸起、南喀-英买力低凸、库车坳陷南部、轮南低凸和中央低凸;准噶尔盆地的克-百断阶带和陆梁隆起,吐哈盆地的台北凹陷及柴达木盆地东部坳陷的第四系。

Abstract:

The distribution characteristics of China's on-land natural gas resources were analysed based on the distribution locality, stratum, origin, buried depth, geography and unproved resources of natural gas.It is considered that the on-land gas resources are mainly distributed in Central and West China (about 40% and 36% respectively).Natural gas reservoirs are primarily in Carboniferous, Ordovician, Permian, Triassic and Tertiary systems.Within the natural gas resources, oil-gas in up to 70% of the total amount, and coal-gas is 29%.Natural gas is buried mostly deeper than 2 000 m, and 80.98% of it is under thick loess domes, hills and desert areas.The gas resources could be divided into 3 types based on their geological and exploration conditions.Among them, type-Ⅰ is basically distributed in the central depressions of Songliao Basin, Tertiary sediments of hydrocarbon-rich depressions in Bobai Bay Basin, the central and east of Sichuan and Ordos Basins, Ih Ju League, Tarim, Junggar, Turpan-Hami and Qaidam Basins in West China.
