In order to clarify the effect of pulsating fracturing on gas comprehensive desorption, experimental study of gas desorption characteristics effected by the pulsating hydraulic fracturing (PHF) and static hydraulic fracturing (SHF) were carried out, the gas displacement amount (GDA) and natural deso...
