摘要:

盐穴地下储气库具有注采率高、短期吞吐量大、垫层气量低并可完全回收等优点。随着中国天然气工业的不
断发展,更多的盐穴地下储气库将建成并投入运行,在天然气储备与调峰中发挥重要作用。中国天然气地下储气库建
设相对滞后,目前已建成投产的盐穴储气库只有1 座,尚未形成系统的盐穴储气库库址评价优选及方法,严重制约了
中国盐穴储气库的发展建设。以金坛储气库为例,从构造特征、盐层发育情况、盐层埋深、盐层厚度、盐岩品位、盖层
性质及厚度、密封性等方面,系统、定量的阐述盐穴地下储气库库址的优选评价指标,旨在为中国盐穴储气库库址的优
选和评价提供可行方法和理论依据,对中国盐穴储气库的建设和发展具有深远的战略意义。

Abstract:

The underground gas storages in salt caverns has the advantages of high injection-production ratio,large accommodation
capacity and low cushion gas content with recycling system. As the development of China′s natural gas industry,
more underground gas storages in salt cavern which play a signigicant role in natural gas reserves and peak shaving will be
built and put into operation. However,China′s underground gas storages construction lags behind,only one underground
gas storages in salt caverns completed and put into operation. The system of evaluation and optimal site selection of underground
gas storages in salt caverns has not formed,which severely restricted the development and construction of underground
gas storages in salt caverns in China. Based on the characteristics of underground gas storage in salt cavern,we studied the
optimization principle of storage site and then comprehensively evaluate the underground gas storage site. The optimization
evaluation index for underground gas storage site has been elaborated systematically and quantitatively in respects of structural
characteristics,development of salt deposit,buried depth of salt layers,thickness of salt beds,property and thickness of cap
rock,tightness,condition of old wells and geographic location,which provides possible ways and theories to evaluate and
optimize the underground gas storage site selection.

Key words: underground gas storage, salt cavern, storage site, optimal selection, geological evaluation
