摘　　要：页岩气存在的页岩层一般孔隙度较小、渗透率较低、石英矿物质含量高、页岩层内页岩气流动性较低,天然形成的裂缝发育程度较高,所以需要对页岩层进行压裂改造才能获得较高且稳定的页岩气产量,非常规压裂技术是页岩气开发的核心技术之一,本文对非常规压裂技术地面配套施工技术进行了具体分析,升级优化页岩气压裂装置,完善压裂工艺地面施工布置,保证了非常规压裂技术施工质量。Generally,shale gas exists in shale layers with small porosity,low permeability,high quartz mineral content and low shale gas mobility,The natural fracture has a high degree of development,so it is necessary to fracture the shale layer to obtain a high and stable shale gas production,Unconventional fracturing technology is one of the core technologies in shale gas development,In this paper,the surface supporting construction technology of unconventional fracturing technology is analyzed,Upgrade and optimize the shale gas fracturing device,improve the ground construction layout of fracturing process,and ensure the construction quality of unconventional fracturing technology.
