| 摘 要： | 根据凝析气在多孔介质中渗流时的相变特征,建立了凝析油-气在多孔介质中的渗流方程,并引入凝析油-气两相拟压力函数使渗流方程线性化;建立了适合于凝析气藏实际情况的三区油气渗流新模型,并求出了凝析气藏油-气拟压力分布的解析解,确立了凝析气井压力恢复试井资料的解释方法;通过某凝析气井的压力恢复实际资料的应用,证明了该模型在凝析气田开发中的实际应用价值。

| Abstract: | On the basis of phase transition characteristic of condensate gas flow in porous medium,established flow equation for condensate oil-gas in porous medium,and introduced dual-pseudo pressure of condensate oil-gas to linearize the flow equation.Then established three-zone condensate oil-gas flow model,obtained analysis solution of pseudo-pressure distribution for condensate oil-gas,and maked certain the interpretation method of build-up test for condensate gas well.Through the application of pressure build-up practical information on the condensate well,it's proved the three-zone model is valuable in condensate gas field exploitation. |
