提出描述天然气地下盐穴储气库动态注采过程的数学模型,其中包括实际气体性质、盐层与库内气体的对流换热、任意连续注采循环时天然气压力和温度随时间的变化。模型可应用于储气库的设计规划,可对各种储气方案比较,并从中选出最佳运行方案
A mathematical model describing the dynamic injection and production process of underground salt cavern gas storage is proposed, which includes the actual gas properties, the convective heat transfer between salt and gas in the reservoir, and the pressure and temperature changes of natural gas over time during any continuous injection and production cycle. The model can be applied to the design and planning of gas storage, comparing various gas storage schemes and selecting the best operation scheme
