摘要
盐岩具有孔隙率低、渗透率小和结构致密等优点，因此它非常适合作为地下能源的存储的场所。在我国，采用盐岩储气库存储天然气和其它能源对环境保护具有非常重要的意义。在盐岩溶腔中进行天然气储备，其中一个重要的前提是确保储气库的密闭性，也就是保证储气库中的天然气在运行期间不外泄，而储库的密闭性和洞室围岩的变形有非常密切的关系。本文对储气库在运行期间的变形和密闭性的关系作了初步的分析总结。
Rock salt has advantages of low porosity, small permeability and compact structure, therefore, it is very appropriate as energy storage place. It is very important to store gas and other energy in rock salt in our country. A significant premise is guarantee the tightness of storage （i.e., make sure the gas can＇t escape from the storage during it is working） before store the gas in salt cavities. The tightness of storage has a very dose relation with the deformation of walls of the cavern, and. In this paper, preliminary analysis and summary for the relation between deformation and tightness have been done during the storage working.
