摘　　要：随着新疆煤层气井开发的行业发展,煤层气从钻井到排采各个施工工艺都在转变,常规压裂工艺在煤层气井压裂施工中已出现技术限制。泵送桥塞射孔联作工艺具有施工排量大、压裂级数不受限制、施工周期短的优点,在煤层气井体积压裂方面开始广泛应用。采用射孔与桥塞带压联作工艺,通过压裂泵车将工具串送入预定位置坐封,桥塞先行坐封,然后射孔,能够提高施工的效率和压裂改造效果。本文将对此技术采用的主要设备、工艺流程、工艺特点、工艺优化及在新疆准南煤层气开发现场的实际应用情况作出阐述。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.
