Multiscale Pore-Fracture Reconstruction and Seepability Enhancement of Coal by Hydraulic Fracturing: A Field-Laboratory Integrated Investigation
Clarifying the transformation mechanism of hydraulic fracturing on coal-rock pore-fracture structures and the associated seepage response is fundamental to the efficient development of low-permeability coalbed methane reservoirs. However, existing studies are hindered by a disconnect between field observations and la...
