这项工作主要分析圆形油藏中心一井口的压力恢复数据，油藏渗透率是距离的函数，也就是说它是径向坐标的函数。本文指出应用反求法可以从直接压力恢复数据估算出渗透率分布。对于渗透率是r和θ函数的情况。本文给出了确定“相同”径向坐标处渗透率分布的反求方法。本文还指出，用压力恢复数据可以近似确定关井时刻油藏压力分布。最后，对非均质圆形油藏中心一口井生产时的稳定流动特性进行了简明的讨论。
This work mainly analyzes the pressure recovery data of a wellhead in a circular reservoir. The reservoir permeability is a function of distance, that is to say it is a function of radial coordinates. This paper points out that the application of inverse method can estimate permeability distribution from direct pressure recovery data. The case for permeability as a function of r and θ. This paper presents an inverse method to determine the permeability distribution at the “same” radial coordinates. This paper also points out that the pressure recovery data can be used to approximate the reservoir pressure distribution at the time of shut-in. Finally, the steady flow characteristics of a well at a heterogeneous circular reservoir center during production are briefly discussed.
