摘　　要：随着油气勘探向地壳深处发展,一些高温高压凝析气藏陆续被勘探发现。目前,这些凝析气藏大多已经进入开发利用阶段。在实际生产中当凝析气沿井筒上升时,随着温度和压力的变化,凝析气会逆凝结形成凝析油,这种烃类相态的转变给其产出剖面解释带来了困难。为解决这一问题,研究提出了一种基于相态图的凝析油产出剖面解释方法,这种方法结合了传统产出剖面解释方法与相态图的相关理论,能够对油气两相凝析油产出剖面进行准确的解释。实际应用表明,该方法是可行的,可为类似剖面处理提供参考。Over the last decade,many oilfields in China have found a number of condensate gas reservoirs.And now,Chinese majority condensate gas resources have entered into a stage of development and utilization.In the process of condensate gas increase along the wellbore,with the reduction of temperature and pressure,condensate gas was changed into condensate oil.The change of phase makes it difficult to calculate each perforating zone's output oil and gas precisely,and this change also makes it impossible to monitor the production of oil well.To solve the problem stated,a new method on the interpretation of condensate oil production profile is proposed.It provides a new idea on condensate oil production profile interpretation.
