桌子山煤田位于鄂尔多斯盆地西缘赋煤构造带，为一轴向近南北的背斜构造，断层较发育且逆断层较多，该区石炭-二叠系含煤地层沉积之后，多次的推覆隆升并未对煤层气产生较大的自然逸散，反而为处于原地煤系发育的煤层气供了有利的聚集场所及赋存条件。本文从煤层气烃源条件、储层物性条件及保存条件三方面出发，系统分析了该区煤层气资源的赋存条件。

Zhuozishan coalifeld is located in the western margin of ordos basin coal structural belt, axial nearly north-south anticline structure, for a more development and thrust fault is more, the permo-carboniferous coal-bearing strata sedimentary, after many times of nappe uplift is not to have great natural dissipation of coalbed methane, instead of in situ coal development of coalbed methane (CBM) for the occurrence conditions and favorable gathered place. Based on the coal-bed gas hydrocarbon source condition, reservoir property and preservation conditions in three aspects, the system analyzes the occurrence conditions of the coalbed methane resources.
