摘要
大张坨地下储气库是中国第一座城市调峰储气库 ,于 2 0 0 0年 12月建成投产 ,是由正在开发的大张坨凝析气田改建而成 ,作为陕京输气管线的配套工程 ,该地下储气库的建成既保证了陕京输气管线满负荷高效运行 ,又部分解决了首都北京市用气调峰和事故应急供气问题。该地下储气库总有效工作气量 6× 10 8m3 ,设 12口可注可采井 ,年采气期 12 0天 ,年注气期 2 2 0天。介绍了该地下储气库的采气、注气、露点控制设计等工艺 ,并结合该气库运行效果介绍了地下储气库地面工程设计中需重点注意的问题 ,对国内其他类似地下储气库的设计具有指导性作用。
Dazhangtuo underground gas storage is the first one for city peak adjustment in China. It was put into operation in Dec. 2000. It is made from Dazhangtuo condensate field that is being developed. It is the counterpart engineering of the gas transmission pipeline from Shaanxi to Beijing. The storage can ensure the pipeline operating with full load and high efficiency,but also solve the problems of Beijing peak adjustment and emergency gas delivering. The effective working gas volume of the storage is 6×10 8m 3 . There are 12 wells,which can be used for both recovering and injecting. The annual gas-recovering period is 120 d,and the annual gas-injecting period is 220 d. The article introduces the techniques of the underground gas storage,such as gas recovering,gas injecting,and dew-point control,etc. With operation situation of the storage,the article points out the major issues that should be paid attention to in the surface engineering design of underground gas storage. It has the guiding role for the design of other similar underground gas storage at home.
