为了探究煤层气非达西渗流中各参数对渗流的影响,通过CT三维重建技术,建立了从现场采集到的6种煤样的真实模型。基于建立的真实模型,进行了在30种不同压力梯度下的煤层气渗流数值模拟试验。模拟试验结果表明:(1)在微观尺度下(

In order to study the influence of parameters on the CBM non-Darcy flow,six real models of various coal samples collected from underground mine were created by 3D reconstruction based on computed tomography. The CBM non-Darcy flow was numerically simulated under 30 different pressure gradients based on the six real models. Accord- ing to the simulation results,some conclusions can be drawn as follows:(1) At the micro-scale (
