本文描述了一种凝析气藏数值模拟的新方法,该方法不仅考虑到了反凝析现象及凝析油的重新汽化现象,还考虑到了任意油田形状,布井方式和非均质性,由于本方法是在体积系数分析(或称BeTa分析)基础上建立起来的,而BeTa分析又与传统的黑油模型分析法类似,所以本文提出的方法在计算上是简便有效的。 本文中还给出了应用此法模拟一个实际凝析气田的某些例子。
This paper describes a new method for the numerical simulation of condensate gas reservoirs that takes into account both retrograde condensation phenomena and revaporization of condensate oil as well as the shape, well pattern and heterogeneity of any oil field due to The method is based on the volume factor analysis (or BeTa analysis), and the BeTa analysis is similar to the traditional black oil model analysis method, so the method proposed in this paper is simple and effective in calculation. Some examples of applying this method to simulate a real condensate field are also given in this paper.
