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.

Key words: Junggar basin, Coal-formed gas, Formation, Exploration, Development
