建设天然气地下储气库具有优化供气、减小于线和压气站投资、调节季节用气、事故应急、战略储备，以及避免油气田初期资源浪费等好处。中国的第一个天然气地下储气库是大庆油田1965年正式投运，1985年食用的萨中东2－1地下储气库。文章介绍大庆油田天然气储气库库址优选标准和从大庆油区优选出的可用于地下储气库改建的喇嘛甸含油气构造、朝51含气构造、四站含气构造。分别对这些油气构造从构造特征、储层特征、盖层隔层密封性、库容等方面进行了地质论证，并计算了储气库库容。其中的喇嘛甸北块天然气地下储气库是目前中国唯一正在运行的地下储气库。

A Research on the Design of Underground Gas Storage Reservoir Construction in Daqing Oil Field

Underground natural gas storage reservoir construction has many advantages,such as optimizing gas supply,declining the investment in gas transmission main and compressor station,gas peak shaving,meeting an urgent need for accident,strategic reserves and avoiding a waste of resources in the initial stage of oil and gas field development,etc.The Sazhongdong underground gas storage reservoir was the first underground natural gas storage reservoir in China which was formally put into operation in 1965 and cut off in 1985 in Daqing Oil Field.The optimum seeking standards of the location of the undergroud natural gas storage reservoir in Daqing Oil Field and the Lamadian oil- and gas-bearing structure,Chao-51 gas-bearing structure and Sizhan gas-bearing structure,which may be used for the underground gas storage reservoir reconstruction,being optimally sought from Daqing Oil Field,are introduced in the paper.The geological conditions of these oil and gas structures,as the properties of structure and reservoir and the sealing of cap rocks,etc.,are demonstrated respectively and their capabilities are calculated also in the paper.It is pointed out that the northern Lamadian underground gas storage reservoir is the only underground gas storage reservoir which is running at present in China.
