摘要： 新疆煤炭资源十分丰富,埋深小于2 000m的资源量达5 412x108t,居全国之首。准噶尔盆地、塔里木盆地及吐哈盆地不但是主要的产煤区,也是煤层气的主要产区。中、下侏罗统煤系地层是形成烃类气体和石油的重要源岩~准噶尔盆地南缘的第一排构造和乌鲁木齐附近以及准东地区煤层发育,是寻找煤层气的有利地区;南缘山前坳陷带的外带,由于煤系地层埋藏太深,应以寻找裂解气和由煤成气向上运移形成的次生气藏为主。

Abstract: Xinjiang possesses the abundant coal resource, with up to 5 412×108t at depth lower than 2 000 m. Junggar, Tarim and Turpan-Hami basins are the main coal mining area and coal-bed methane productive area, in which Mid-Lower Jurassic coal-seam is major source rock foming hydrocarbon. The first row of structure in south margin of Junggar basin, nearby Urumqi area, and Zhun-dong area with well-developed coal-bed are favourable areas to find coal-bed methane. In the extenal of piedmont depressional zone in the south margin, themocracking gas and secondary gas reservoirs re sulted from coal-bed gas upward migrating should be considered as the main objective of exploration because of deeper buried depth of coal-seam.
