摘　　要：二叠系上统龙潭组是区内重要含煤地层,也是煤层气勘探开发的主要目标层位。以松藻矿区实施的QM1井组为例,对其储层条件、压裂改造工艺、施工过程、改造效果以及产气情况进行了介绍,结合实际研究指出了目前限制重庆地区煤层气开发取得突破的关键技术问题。The Longtan Formation of Upper Permian,which contains abundant coal resources,is the primary target for coalbed methane exploration and development in the region.Using the example of the QM1 well group implemented in the Songzao Mining Area,this paper presents an overview of the reservoir conditions,the fracturing technology,the construction processes,the stimulation effects,and the drainage and production.By combining these findings with actual research,the critical technical challenges that hinder coalbed methane development in Chongqing are identified.
