摘要
基于彬长矿区大佛寺井田低煤阶、高渗煤层的地质特征,采用数值模拟方法优化多分支水平井井型,确定了主支长度、分支个数、分支长度和分支夹角的适宜范围,并预测了大佛寺井田的煤层气开发潜力,为大佛寺井田低阶煤煤层气的开发提供理论依据。
Based on the geological characteristics of low rank and high permeability coal seam in Dafosi coalfield in Binchang mining area, the well pattern of multi-lateral horizontal well is optimized by numerical simulation, the suitable range of the length of the main branch, the number of branches, the length of the branch and the angle of the branch are determined, and also the potential of CBM development is predicted in Dafosi coalfield. The results provide theoretical basis for CBM development of low rank coal in Dafosi coalfield.
