摘　　要：随涪陵、长宁、威远等页岩气勘探开发的突破,目前开发对象逐步转向深层。深层页岩储层地应力高、水平两向应力差异大、层理和天然裂隙分布复杂、岩石塑性特征强,对压裂改造技术带来新的挑战。分析总结深层页岩气储层压裂改造难点基础上,研究提出针对性技术措施,现场应用效果显著,对深层页岩气储层压裂改造具有重要指导意义。With the breakthroughs in the exploration and development of Fuling,Changning and Weiyuan shale gas, the object of development is gradually shifting to the deep strata.Deep shale reservoir has high in-situ stress and great difference in horizontal two-dimensional stress.The complex distribution of bedding and natural fissures and the strong plastic characteristics of rocks bring new challenges to the fracturing technology.Based on the analysis and summary of the difficulties in fracturing reconstruction of deep shale gas reservoirs,the pertinent technical measures are put forward.The field application effect is remarkable,which has important guiding significance for fracturing reconstruction of deep shale gas reservoir.
