摘　　要：为了确定白山坪井田煤层气勘探前景,基于对白山坪井田5号和6号煤层南北翼煤层气成藏主控因素的对比研究,探寻了该井田煤层气的勘探潜力以及成藏的有利区带。结果表明:白山坪井田5号和6号煤层南翼煤层厚度大,这2层煤由北向南煤层厚度逐渐增厚,由向斜翼部到核部,煤层稳定性增强,有后期岩浆侵入供热促使烃源岩二次生烃,此外南翼断层较少,仅发育2条小断层,顶板渗透性差并且厚度较大,保存条件优于北翼。所以煤层气成藏的主控因素来看,白山坪矿区南翼整体勘探前景优于北翼。In order to determine Baishanping＇s exploration prospects of coal bed methane, the authors studied the coal bed methane exploration potential and the accumulation of favorable zones based on finishing the comparative study of Baishanping Mine No.5 and No.6 seam of north and south wing of coal bed methane reservoir control factors.The results showed that thickness of Baishanping No.5 and No.6 coal seam was more thick in south wing.The two sets of coal seam thickness became gradually thicker from north to south.The stability of coal seam improved from side to core of syncline.The late magmatic intrusive heating to hydrocarbon source rock resulted in secondary hydrocarbon generation.In addition, fault development less, only two small faults in south,roof poor permeability and thickness were larger than the north wing, preservation condition was better than the north wing.So from the main control factors of coal bed methane reservoirs forming of Baishanping, overall exploration prospect in south wing was better than the north wing.
