| 摘 要： | 分析高温高压凝析气藏开发动态时，必须考虑气相中水蒸气及岩石变形的影响。为此，在引入气藏内部烃类摩尔质量平衡原理及广义凝析气藏物质平衡原理的基础上，考虑气藏气相水蒸气含量及岩石颗粒的弹性膨胀作用，推导了气相水蒸气含量、天然水驱、注气及带油环条件下的高温高压凝析气藏物质平衡方程通式。实例证明，利用忽略气相水蒸气含量或岩石变形的凝析气藏物质平衡方程和容积法计算的高温高压凝析气藏的储量均偏大，其误差大于5%，这说明新建立的考虑气藏气相水蒸气含量及岩石颗粒的弹性膨胀作用的高温高压凝析气藏物质平衡方程是可靠和准确的。

| Abstract: | The effect of water vapor and rock deformation in gas phase must be considered in the analysis of the production behavior of high temperature and high pressure gas condensate reservoirs.For this purpose,based on the hydrocarbon molar mass balance principle and the generalized material balance principle,and with the content of water vapor and elastic expansion of rock particles in gas reservoirs taken into account,a general formula of material balance equation for HTHP gas condensate reservoirs was developed... |
