摘要
本文根据非达西低速渗流的理论,提出了凹型压力恢复曲线的基本公式,并提出了直线分析的两种方法。这两种分析方法的结果是完全一致的。使用这两种方法分析凹形压力恢复曲线,可以获得原始地层压力、渗透率、起始压力梯度、流动系数等储层参数。这两种方法既简便又方便。
A basic formula for concave pressure-restoring curve and two methods of linear analysis are proposed , applying the theory of non-Darcy low speed seepage flow. The results from the two analytical methods are entirely consistent , and several reservoir parameters , i.e the primary stratigraphic
essure, permeability, initial pressure gradients and flow coeficient, can be obtained by using the two methods in the analysis of concave pressure-restoring curve. They are simple and convenient.
