文摘
A new method based on polynomial fitting is introduced to analyze the pulse decay data. The permeability first remarkably decreases with higher confining pressure and then at a much slower speed. The effect of fracture roughness on the permeability is related to the confining pressure. The hydro-mechanical coupling reduces the roughness of rock fractures.
