摘　　要：本文给出了在矩形封闭外边界条件下,弱压缩液体在双重孔隙介质中流向垂直裂缝井所构成的二维抛物型方程组的 Laplace 变换数值反演解。这些解的特殊情况与已有的均质孔隙介质中的结果符合得较好,可以用于垂直裂缝井试井的分析和解释。This paper gives a Laplace transform solutions of two-dimensional para- bolic differential equations for transient flow in a well bore with a single infi- nite-conductivity vertical fracture in rectangular closed reservoir with double porosity.Agree the results with those already reported and this solutions for special case are very satisfactory.Therefore,these results can be used to ana- lyse the transient pressure test data when a vertical fracture with a infinite conductivity arround a well bore is occured.
