地下储气库天然气损耗及控制

GAS LOSS AND CONTROL OF UNDERGROUND GAS STORAGES

从1999年以来,陕京输气管道工程已相继建成了大张坨、板876和板中北3座地下储气库,这些储气库对于北京、天津和华北地区冬季调峰供气起到了不可替代的作用。目前与“西气东输”管线相配套的地下储气库正处于设计和建设当中,而更多的地下储气库也正在被规划和研究中。天然气损耗是储气库的特有参数之一,它不仅关系到储气库运行的经济特性,而且还是评价一个储气库成败的关键。文章根据几年来对已建储气库的运行观察、研究,对储气库天然气的损失进行了归纳和总结,并有针对性地提出了控制措施,对储气库的设计、运行及减少天然气损耗有一定的指导意义。

Since 1999, 3 underground gas storages of Dazhangtuo, Ban 876 and Banzhongbei have been built for Shaan-Jing Gas Transmission Pipeline. The gas storages are very important for winter peak-cutting gas delivery of Beijing, Tianjin and North China area. Now, the underground gas storages for 'West-East Gas Transmission pipeline' are being designed and built. More underground gas storages are being investigated. Gas loss is one of the special parameters of gas storages, which not only is related in the economic features of gas storage operation, but also is the key to evaluate whether or not a gas storage is successful. Based on the observation and study of the built underground gas storages for several years, the situation of gas loss is summed and the countermeasures are proposed, which has guiding signification for the design and operation of underground gas storages to reduce gas loss.
