摘　　要：通过对库拜煤田铁西区内煤岩组分、煤岩煤质、孔渗和含气性特征的分析,以及对铁西区内自然地理、火烧区、构造等因素的讨论,进一步揭示了研究区内的煤层气成藏条件和其他因素。主要阐明了研究区内主力煤层的孔渗、含气性特征以及煤层气逸散、封堵和成藏的主要特征。本次研究成果有望为南疆煤层气的进一步开发利用提供理论依据。Based on the analysis of the composition,the quality,the porosity,the permeability and the gas bearing characteristics of the coal in Tiexi Area of Kubai Coalfield,and the discussion of the natural geography,the burning area,the structure and other factors in Tiexi area,the paper further reveals the coalbed methane accumulation conditions and other factors in the studied area.The characteristics of pore permeability and gas bearing of main coal seam in the studied area as well as the main characteristics of CBM escaping,plugging and reservoir formation are mainly expounded.The research results are expected to provide a theoretical basis for the further development and utilization of coalbed methane in Southern Xinjiang.
