| 摘 要： | 本文依据段塞流的特点,提出了双渗透地层存在稳态窜流的段塞流测试或DST测试流动期的数学模型,并分别用Laplace变换和有限差分方法求其半解析解和数值解;绘制出了反映压力特征的典型曲线。利用该曲线可以分析段塞流或DST流动期的数据,得出双渗地层的特性参数。

| Abstract: | This paper presents the physical and mathematical models ofslug flow in the double permeability reservoir, and gives the solutions to the mathematical model by means of Laplace transforms and finite difference methods. In addition, type curves are given to analyze the pressure behavior of the flow. Reservoir parameters can also be estimated. |
