双重介质地层的凝析气井定流压分析模型及应用

在凝析气井生产过程中地层流体会产生复杂的相变，如果井底析出凝析油会造成严重的井底污染，影响气井产量。为了避免这种现象，凝析气井多以定流压的状态进行生产，因此，从凝析气井生产的这一实际情况出发，改变了以往传统的常产量试井分析理论，建立了适应于凝析气井试井分析的定流压渗流模型，绘制了试井理论图版，以适用于凝析气井的试井分析，可以通过凝析气井的产量历史解释出地层参数，还可以进行产能预测，并给出了应用实例。

Analysis Model and Application of Constant Flow Pressure in Condensate Gas Well in Dual Media Formation

In the process of condensate gas well production,formation fluid may have complicated phase change.Condensate oil depositing in bottom hole may pollute the bottom seriously and reduce production.In order to solve this problem,condensate gas wells are mostly produced in constant flow pressure status.Thus this paper changes the conventional constant production well test analysis theory and constructs a constant flow pressure model which is adaptable for condensate gas well test.It plots well test theory chart suitable for condensate gas well test analysis.This model can interpret formation parameters through production of condensate gas well,and can predict productivity.The paper gives relative case of application.
