凝析气藏的模拟计算是个十分复杂的工作。以较为简单的方式——黑油模型思想——考虑凝析气藏模拟问题,是本文的尝试。文中叙述了问题的提法、物理模式、数学模式及求解途径等。并且,详述了不同情况下差分方程的推导过程。文中附有计算实例。实例给出了不同干气回注情况下的凝析油采出情况。分析了计算结果,得出“苏1潜山最佳回注比为0.7”的结论。
Condensate gas reservoir simulation is a very complicated task. In a relatively simple way - the idea of black oil model - considering the problem of condensate gas reservoir simulation, this article attempts. The article described the problem formulation, physical model, mathematical model and solving ways. In addition, the derivation of difference equations under different conditions is described in detail. Text attached to the calculation example. The example gives the condensate recovery under different dry gas injection conditions. The results of the calculation are analyzed and the conclusion that “the best injection ratio of Su 1 buried hill is 0.7” is obtained.
