根据煤田勘探资料、实测统计数据及试验数据,对大佛寺井田的地质构造、煤层空间展布特征和煤储层特征进行分析;通过定性定量分析,系统地探讨了该区构造发育特征、煤层厚度、埋深、围岩条件及水文特征对煤层气含量的影响,认为构造发育情况、煤厚、围岩条件和水文特征对含气量均有不同程度的控制作用,埋深对含气量的影响不明显,并指出该区煤层气储量丰富,地质条件良好,具有较好地开发利用价值。
According to coalfield exploration data, measured data and experimental data, the geological structure, coal seam space distribution characteristics and coal reservoir characteristics of Dafosi Minefield are analyzed. Through qualitative and quantitative analysis, the characteristics of tectonic development, coal seam thickness , Burial depth, surrounding rock conditions and hydrological characteristics on CBM content, it is considered that the structural development, coal thickness, surrounding rock conditions and hydrological characteristics have different degrees of control on the gas content, and the influence of burial depth on gas content is not Obvious, and pointed out that the area has rich coalbed methane reserves and good geological conditions, so it has good value for development and utilization.
