| 摘 要： | 本文在文献1]对均质地层分析结果的基础上，用拉氏变换及stehfest数值反演方法研究了针对双重介质地层井筒储集系数呈线形变化，指数变化等情形下有效井径数学模型的近似解，绘制相应的典型曲线，并对影响曲线形态的参数进行探讨，这对于用实际资料进行试井解释时合理使用其早期数据有很好的参考作用。

| Abstract: | Based on the analytic result of homogeneous strafa and utilized the laplace transform and stehfest numerical inversion, the approximate solution of a mathematical model for well di-ameter under the condition of linear and potential variations of wellbore storage coefficient of the double porosity system is studied. Accordingly, typical curves are created and the parameter af-fecting the shape of curves is discussed. The results studyied are proved to be useful in the ratio-nal application of data of the early stage to the interpretation of well testing. |
