With the development of the coalbed methane well development industry in Xinjiang,various construction techniques for coalbed methane from drilling to drainage are changing.Conventional fractu-ring techniques have encountered technical limitations in coalbed methane well fracturing construction.The pumping bridge plug perforation combined process has advantages such as large construction dis-placement,unrestricted fracturing stages,and short construction period,and has been widely used in the volume fracturing of coalbed methane wells.By using the combined process of perforation and bridge plug with pressure,the tools are sent to the predetermined position for sealing by a fracturing pump truck.The bridge plug is first sealed,and then perforation is carried out,which can improve the efficiency of con-struction and the effect of fracturing transformation.This article will elaborate on the main equipment,process flow,process characteristics,process optimization,and practical application of this technology in the development of coalbed methane in Zhunnan of Xinjiang.
