| Abstract: | Aiming at the problem of poor gas production caused by blockage of gas channel in coalbed methane wells，the main reasons for low-yield wells in some areas with good geological conditions in China and the commonly used techniques for plugging plugging were analyzed.The high-energy fluid plugging technology method was proposed.The technical process of high-energy fluid fracturing，dredging and cleaning process was studied，and basic data such as matching of parameters used in the process and evaluation of plugging effect were obtained.Through the practical application of the high-energy fluid deblocking technology method，it had certain stimulation effect on individual low-yield wells，and provided information for solving the current situation of low-production of CBM wells. |
