摘　　要：通过对徐往子井田控气地质条件、含气性及储层物性的研究,初步分析了徐往子井田煤层气的成藏地质条件。分析认为:研究区煤变质程度高,煤层气资源量丰富,成藏主控因素为构造控气;本区以封闭式深埋藏为主,除断层位置外,封闭性较好,但透气性差,渗透率低,需经后期改造。The coalbed methane reservoring geological conditions of Xuwangzi mine field are preliminarily analysised based on the study of gas-controlling geological conditions,gas bearing and reservoir property. The analysis shows that：In the area,the metamorphic degree is high,the coalbed resources is rich and the main control factor is under structure control; The main sealing feature is enclosed and deeply buried,and the coal sealing is preferable except the area near the fault,but permeability is amplitude and permeability is very low. The late reformation will be necessary in exploitation.
