中国第一座地下储气库——大庆萨尔图油田一号储气库,于60年代后期成功地进行了注采天然气试验,该储气库是利用下白垩统萨零组枯竭气层和原采气井进行注采试验的。储气库位于大庆油田主力油层上部,地层厚度为30～50m,气层下部为稳定分布的厚18m黑色泥岩,与主力开发层系——萨尔图油层相隔,储气库上部为厚200m的黑色泥岩盖层, China’s first underground gas reservoir, Daqing Saertu Oil Field No.1 gas storage reservoir, successfully conducted the injection-natural gas test in the late 1960s. The gas reservoir was constructed using the depleted gas layer of the Lower Cretaceous Sa Xu Formation The original gas well injection test. The gas reservoir is located in the upper part of the main oil layer in Daqing Oilfield. The thickness of the reservoir is 30 ~ 50m. The lower part of the gas reservoir is a stable distribution of 18m thick black mudstone. Separated from the main development zone - Salto oil reservoir, the upper part of the gas reservoir is 200m thick Black mudstone cover,
