INVESTIGATION ON DYNAMIC MECHANISM OF FAULT SLIP AND CASING DEFORMATION DURING MULTI-FRACTURING IN SHALE GAS WELLS

Investigation on dynamic mechanism of fault slip and casing deformation during multi-fracturing in shale gas wells

Abstract Fracturing horizontal well casing deformation has become very prominent, particularly in tectonic stress-concentrated shale gas fields, limiting the efficient development progress of shale gas.The main failure mode of casing vibrators-kits shearing deformation had been attributed to fault slip caused by multi-fracturing.The current researc
