摘要:Coalbed methane (gas) is a high quality and clean resource, but it also causes disasters in coal mines in China. The low permeability of coal seams is the main reason that developing coalbed methane (CBM) as an energy resource is difficult, so increasing coal seam permeability is...

摘要:When coal bed methane (CBM) drainage boreholes cross fractured, soft, or water-swelling strata, they collapse and block frequently. Borehole blockages result in a rapid decrease in CBM extraction ability, which leads to a reduction in CBM output and threatens coal mine safet...

摘要:Hydraulic fracturing is used widely to stimulate coalbed methane production in coal mines. However, some factors associated with conventional hydraulic fracturing, such as the simple morphology of the fractures it generates and inhomogeneous stress relief, limit its scope of...

摘要:When drilling coal-bearing sequences to enhance coal seam permeability by hydraulic fracturing (HF), the location where fractures are initiated is important. To date, most research on fracture initiation has studied the problem in two dimensions. In this study, a three-dimensiona...

摘要:Initial cracking pressure and locations are important parameters in conducting cross-measure hydraulic fracturing to enhance coal seam permeability in underground coalmines, which are significantly influenced by in-situ stress and occurrence of coal seam. In this study, stress st...

摘要:High-pressure hydraulic fracturing technology in coal and coal bed methane mines can lead to roof and floor damage, and fracture initiation disorder that leads to a “blank area”, and other issues. A new method of hydraulic fracturing is proposed to increase the homogeneous p...

摘要:Due to the increasing depths of coal mines and the low permeability of some coal seams, conventional methods of gas drainage in underground mines are facing many problems. To improve gas extraction, a new technique using water jets to drill tree-type boreholes in coal seams ...

摘要:Abstract(#br)When fracturing a shale gas reservoir with supercritical CO 2 , the interaction between CO 2 and shale will change the pore structure, thus affecting the mechanical properties of shale. To confirm the influencing mechanism of pore structure changes on mechanical...

摘要:Abstract(#br)Considering the problems happening to sealing materials for hydraulic fracturing borehole in underground coalmines, such as shrinkage, poor sealing effect, high cost, and improper sealing length, a new hydraulic fracturing sealing material consisting of cement, early...

摘要:Abstract(#br)Deep coal bed methane generally has a higher formation temperature than shallower coal, which can have important consequences for hydraulic fracturing. In this study, the pore characteristics of coal samples treated by viscoelastic surfactant (VES) fracturing fl...
