摘要(Abstract)：

地下储气库被许多国家认为是最安全、经济、高效的天然气储存、调峰设施,大庆地区冬夏用气不均衡,需建立地下储气库用于调峰。通过对大庆S储气库群的多种条件分析认为:储层上部发育稳定的巨厚泥岩盖层,对天然气起到了很好的封盖作用,断层整体密封性好,天然气不渗漏,储气库整体封闭性好;储层为单层砂体,分布稳定,储层物性条件非常好;气藏整体连通性也很好,受边底水的影响很小,设计的储气库运行参数合理。大庆S储气库群具备建库的有利条件,改建储气库可行。
For many countries,the underground gas storage is considered to be the most safe,economic and highefficiency facility to the natural gas storage and peak shaving. In Daqing area,there is unbalanced gas use between the winter and summer,so the underground gas storage is urgently needed for the peak shaving. Through the analyses on the conditions of Daqing Gas Storage Group S,the thick and stably well-developed mudstone caprocks in the upper reservoirs are considered to have much better sealing effects on the natural gas,so are the whole sealed property of the faults,thus the natural gas gets no leakage,the overall gas storage is closed very well; the reservoirs are single and stable sandbodies,which are characterized by very good conditions of the physical properties; the connectivity of the gas reservoirs is also pretty good,and moreover there is a little effect from the edge and bottom waters,the designed parameters of the gas storage are reasonable. Group S possesses favorable conditions to build the underground gas storage and moreover is feasible to rebuild the storage.
