Hydraulic conductivity of fractured bedrock
WebThe hydraulic conductivity at different test intervals of a borehole is remarkably enhanced at highly fractured zone or contact zone, but within a rock unit of weak heterogeneity, it decreases with the increase of depth. Key Points: The Q-P curves by HPPTs were divided into Darcy, non-Darcy, and fracking phases WebThe hydraulic conductivity (K) of open fractures and fractured rock zones can be high; however, it varies by orders of magnitude from 10 -5 m/s to 10 -12 m/s, depending on the …
