地下储气库对解决冬、夏季天然气供需矛盾、保障用户需求、优化集输系统功能有重要作用。在对国内外相关资料调研分析的基础上,认为地理位置优越、构造简单且不含H2S等有害气体的枯竭油气藏是建设地下储气库的最佳选择。大港油田建设大张坨地下储气库的成功经验证实:地下储气库储层物性好坏及均质性强弱是地下储气库井位选择正确与否的关键,圈闭封闭性好坏是储气库建设成败的关键,库容量大小是储气库调峰能力大小的重要标志。

The underground gas storage plays an important role in aspect of adjusting the contradiction of supply and demand of natural gas in winter and summer, ensuring  the requirement of consumer and optimizing the function of gathering and transferring system. On the basis of collection and analysis of abroad related data, the  best option of underground gas storage established is put forward, that is, the depletion reservoir with ascendant geographical location, simple structure and without deleterious gas, such as dioxide sulfur and so on. At the same time, the following results are proved through the successful experience of underground gas storage construction of Dagang oil field, that is, the key of well location arrangement of underground gas storage is reservoir physical characte  ristics and homogeneity, the success key of gas storage construction is focused on trap confine, and the storage capacity is the important mark of peak-adjusting capability of gas storage.
