盐穴储气库溶腔过程中腔体净容积及油水界面计算实例

A model for calculation of the net volume and oil-brine interfacein in salt gas storage

建立地下盐穴储气库溶腔净容积和油水界面计算模型,利用溶腔过程中压力、密度等生产及相关地质参数,计算腔体净容积和油水界面深度,为不同阶段的溶腔腔体体积评估和溶腔井下工况诊断提供依据。目前该溶腔净容积及油水界面深度计算方法已经在金坛盐穴储气库溶腔现场得到了应用。

Create a model for the calculation of the net volume and oil-brine interface in the underground salt gas storage. Calculate the net volume and the oil-brine interface with the operational and geological parameters such as pressure, density, which provides proofs for the evaluation of the cavern＇s volume and the diagnosis of the downhole working conditions. This calculation method is currently being applied in the Jin Tan salt cavern underground gas storage on site.
