摘　　要：全球气候变暖正在严重威胁着人们赖以生存的家园,在“双碳”背景下,实施CO_(2)减排工程是各个国家保障可持续发展必走的路径。开展CO_(2)地质封存研究,具有温室气体防控和资源开发利用双重效益。选择甘肃省崆峒区峡门一带二叠系下统山西组的煤D层作为本次CO_(2)地质封存的研究对象,对煤D层的分布特征、储集条件、煤炭资源量和盖层发育情况等封存CO_(2)的地质条件进行了综合研究,并估算得出区内CO_(2)可埋藏量为67.07万吨。Global climate change is seriously threatening the homes that people rely on for survival.In the context of"carbon peak and car-bon neutrality",implementing CO_(2) reduction projects is a necessary path for countries to ensure sustainable development.Research on CO_(2) geolog-ical storage offers dual benefits of greenhouse gas prevention and control,as well as resource exploitation and utilization.The coal D layer of the Shanxi Formation of the Lower Permian Series in the Xiamen area of Kongtong District,Gansu Province,was chosen as the focus of the research for CO_(2) geological storage.A comprehensive study was conducted on the geological conditions for CO_(2) storage,including the distribution characteris-tics,storage conditions,coal resources,storage conditions,and cap development of the coal D layer.It is estimated that the amount of CO_(2) buried in the area is 670700 tons.
