| 摘 要： | 根据凝析气在多孔介质中渗流的相态变化特征,建立了凝析油-气不稳定渗流的基本微分方程,同时引入了凝析油-气两相拟压力函数对渗流方程进行了线性化处理;针对形成不同流体区域的凝折气藏、有边水的凝析气藏、岩性尖灭凝析气藏及井底存在污染和改善等多种情况,针对存在过渡区的复合凝析气藏建立了凝折油-气渗流新模型,模型更适合凝析气藏实际情况,并求出了凝析气藏油-气拟压力分布的拉氏空间解析解,确立了对凝析气井进行压力恢复试井的具体解释方法,从而为指导气田的合理开发提供可靠的依据.

| Abstract: | According to the phase change of condensate gas flowing in porous medium,characteristics,set up the condensate- gas unsteady seepage differential equation,At the same time introduced the condensate- gas seepage equation of two phase pseudo pressure function of the linearization;To form different fluid field of condensate gas reservoir,condensate gas reservoir of edge water,lithologic pinchout condensate gas reservoir and bottom hole existing pollution and improve the situation,the existence of condensate gas reservoir has been established the practical situation transition zone compound gas reservoir in the condensate oil-gas seepage new model,and the condensate gas reservoir oil- gas pressure distribution of the Laplace space analytic solution,established the pressure recovery of condensate gas well well test specific explanation method,to guide the rational development of gas fields to provide reliable basis. |
