摘要
通过梳理近年来峰峰矿区煤层气(煤矿瓦斯)相关资料,从煤层赋存规律、构造特征、含气量、储层特征、渗透率等多个方面研究分析了峰峰矿区煤层气赋存规律,总结了峰峰矿区煤层气含气量主控因素,分析了峰峰矿区抽采现状,估算了峰峰矿区煤层气资源量。研究表明,矿区煤层储层具备以裂隙为主、孔隙度很高,透气性较好,围岩的封闭条件较好,含气量也较高的物性特征;结合以上特点建议在矿井生产区加大井下煤层气的抽采力度提高资源利用率,在后备区建立中小型煤层气地面开发区。
Based on recent years CBM(coalmine gas)related data sorting in the Fengfeng mining area,have studied and analyzed the area’s CBM hosting pattern from multiple aspects of structural features,methane content,reservoir features and permeability etc.Then have summarized CBM content main control factors,analyzed CBM drainage status quo,estimated CBM resources.The study has shown that the reservoir has physical properties of mainly fissures with high porosity,better gas permeability and surrounding rock sealing conditions as well as high methane content.Combined with above features have proposed to step up underground CBM drainage and promote resource availability in mine production region,establish medium to small CBM surface exploitation areas in subsequent mining region.
