| 摘 要： | 针对传统凝析气藏油气分布模型存在的问题，建立一种新的三区复合凝析气藏试井模型，并推导出外边界为无穷大、封闭和定压3种情况下井底压力的表达式，绘出了相应的典型样板曲线，并对三区复合凝析气藏的井底压力动态变化及影响因素进行分析和讨论。该方法采用的新模型更符合凝析气藏的开采过程中的真实情形，对该类气藏的开采分析研究具有现实的指导意义。

| Abstract: | A new well testing model is established for the complex condensate gas reservoir in Area 3. An expression of downhole pressure has been derived for 3 conditions such as infinitely great external boundary, sealed and given pressure, and corresponding type - curves are presented. Dynamic change of downhole pressure and its influence factors are analyzed and discussed for this reservoir. This new model closely accords with the practical process of condensate gas reservoir recovery. This may guide the recovery analysis and study of such reservoirs. |
