Objective The hydraulic fracturing is still an effective technology for the exploitation of coalbed methane(CBM).However,after the hydraulic fracturing operation,the high water cut or sudden water flooding of CBM well usually occurs due to upward migration of bottom water,which is called water channeling(water inrush).This problem has been severely limiting the hydraulic fracturing effect of CBM wells.Some studies show that the aquifuge and cement
