摘要
气藏物质平衡方程式，是气藏工程中的重要方法。它不但可以确定气藏的原始地质储量和可采储量，而且还可以判断气藏的驱动类型，以及预测未来的开发动态。基于在气藏开发过程中，不同驱动力的作用，包括气体、束缚水和岩石的弹性膨胀驱动，以及天然水侵驱动，并考虑地下体积累积平衡的原则，对定容气藏和水驱气藏的物质平衡方程式，进行了完整的推导，其结果也可作为凝析气藏的物质平衡方程式。
Material balance equation of gas reservoir is an important method in gas reservoir engineering. It can not only be used to determine original gas in-place and recoverable reserves of gas reservoir, but also judge the drive type and predict future development performance. Based on the effect of different drive energy including elastic expansion of natural gas, Irreducible connate water and rock, along with natural water invaded as well as the principle of the cumulative volume balance, a new derivation of material balance equation for valumetric and water drive gas reservoirs are proposed in this paper.
