True Triaxial Physical Simulation Experiment on the Fracture Propagation Law of Hydraulic Fracturing for Horizontal Wells in the Roof of Soft and Low-Permeability Coal Seams
The key to exploiting coalbed methane in soft and low-permeability coal seams by deploying horizontal wells in roof strata lies in whether hydraulic fractures can propagate into the coal seam after initiating from the roof. True triaxial physical simulation experiments based on 15 artificially cast fracturing specimens...
