【摘要】 通过建立底水驱枯竭气藏型天然气地下储气库的注采动态数学模型，采用分数步长解法，以储库平均地层压力和含水饱和度的动态变化特征为目标函数，数值模拟出储气的历史过程，预测储库的储存容量，研究储库注采的动态特征。更多还原

【Abstract】 By establishing accurte mathematical models of underground gas storage with water driving and using method of mathematical simulation, dynamic storage characteristics and permeating process were studied, history processes of underground gas storage were simulated and effecting factors were analysed.更多还原
