摘　　要：页岩属于低孔低渗储层,其开发难度非常大,90%的页岩气井需经过储层改造才能获得较为理想的产气效果,压裂技术是进行储层改造、提高产能的最主要手段。为了全面系统地了解各种压裂技术,通过大量的文献调研及整理研究,简单介绍了页岩气压裂技术的发展历程,并详细论述了目前应用于页岩储层改造的主要压裂技术的理论基础、技术特点、适用性及各种压裂工艺间的差异性。同时,介绍了几种近些年发展产生的新型压裂技术,包括混合压裂技术、纤维压裂技术、通道压裂技术,以及在页岩储层压裂中的应用情况及展望。针对我国页岩气勘查开发工作刚刚起步,施工经验不足的现实情况,了解各种压裂技术特点,寻找适合我国页岩储层的压裂技术,对我国页岩气勘查开发具有重要意义。Shale is a low porosity and low permeability reservoir, whose development is very difficult, 90% of the shale gas wells need to be reconstructed to get ideal gas production results, Fracturing technologies are the main means of reservoir reconstruction and production capacity enhancement. In order to fully understand the various fracturing technology systems, through a lot of literature research and organized research, this paper briefly describes the shale gas fracturing technology development process, and discusses in detail the theoretical basis, main technical characteristics, and applicability, as well as differences between the various fracturing technologies, In addition, several new fracturing technologies and applica- tion situation are introduced, including hybrid fracturing, fiber FRAC fracturing, HiWAY channel fracturing. Besides, their application forecast is also mentioned. In view of the shale gas exploration and development work has just started and the reality of lack of construction experience in China, to understand the characteristics of various fracturing techniques, looking for our shale reservoir fracturing technology has important implications for the development of shale gas exploration.
