摘　　要：页岩气作为一种重要的非常规天然气资源,开发页岩气对缓解中国天然气资源紧缺状况、改变能源结构、保障国家能源安全供应具有重要战略意义,文章深入探讨了影响CH4解吸的因素,综述了注入CO2提高页岩气采收率方法的可行性。阐述了注入CO2提高页岩气采收率的方法的不足,讨论了CO2地质封存的泄露风险及环境风险检测,对未来注入CO2提高页岩气采收率的研究方向进行了展望。As an important unconventional natural gas resource, the development of shale gas is of great strategic significance to alleviate the shortage of natural gas resources in China, change the energy structure, and guarantee the secure supply of national energy. This paper discusses in depth the factors affecting the desorption of CH4, and reviews the feasibility of the method of injecting CO2 to improve the recovery rate of shale gas. It also describes the shortcomings of the method of injecting CO2 to improve shale gas recovery, discusses the leakage risk and environmental risk detection of CO2 geological storage, and looks forward to the future research direction of injecting CO2 to improve shale gas recovery.
