摘要
利用废弃的中、高渗透砂岩气藏改建的天然气地下储气库的库容量、有效工作气量及调峰能力是衡量储气库的重要指标 ,其中库容量是储气库其他重要指标设计的基础。因此 ,如何准确计算储气库的库容量是非常关键的 ,它对储气库建设的成败以及对上游天然气开发和下游天然气需求都将起到极其重要的调节作用。通常在建设储气库时的库容量比利用气藏开发数据计算的库容量 (地下有效储集空间 )要小 ,因而在改建成储气库后特别是第一个注气周期内 ,必须对储气库的库容量进行复核。文章采用改进的物质平衡方法对气藏动态储量进行了计算 ,并对改建为储气库后的库容量进行了复核 ,经实例应用 。
The capacity,effectively working gas volume and peak shaving capability of the underground natural gas storage reconstructed from the abandoned high medium permeability sandstone gas reservoir are the important indexes of evaluating the gas storage,in which the capacity is the basis of designing the other important indexes of the gas storage.Therefore how to calculate accurately the capacity of the gas storage is very important.It plays an very important adjustment role in the success of failure of constructing the gas storage and in the upstream natural gas development and downstream natural gas demands.In general,when the gas storage is constructing,its capacity is smaller that the one (subsurface effective reservoir space) calculated by use of gas reservoir development data.So,it is necessary to check the capacity of the gas storage after the gas storage's being reconstructed,especially in the first gas in jection cycle.The gas reservoir dynamic reserves were estimated by applying the modified material balance method and the capacity after the gas storage's being reconstructed was checked up.Through practical application,it was proved that the prediction result is satisfactory.
