Experimental study on stress-permeability of high rank coal samples before and after hydraulic fracturing
Hydraulic fracturing technology has become a key technical means to improve coalbed methane (CBM) yield. The evolution of CBM reservoir permeability before and after hydraulic fracturing reflects the induced fracturing level. By means of fracturing and stress-permeability experiments on four high ra...
