Coalbed methane mining-insight from multiscale multiphysical simulation on supercomputers

摘要

Modern computational techniques are invaluable components of every engineer's toolkit and every scientist's laboratory.The main challenge for computational analysis of coalbed methane mining is to consider the multiscale heterogeneity and the related multiphysical phenomena in natural and/or enhanced geo-materials (e.g.coal seam and its interburden).Heterogeneous geomaterials typically possess a multitude of physically significant scales and each of these scales requires appropriate modeling.Heterogeneous structures on the microscale (i.e.mineral grains, pore space and micro-cracks) are often close in size to a characteristic length for the macroscopic pattern for such as subsurface flow and transport.Hence these structures strongly influence macroscale processes.
