| 摘 要： | 本文采用傅立叶变换方法，求得了弱可压缩液体在双孔介质中二维不定常渗流的拉氏空间解，研究了非稳态变换双重介质裂缝储量比ω和介质间传导系数λ对无限导流垂直裂缝井的压力及压力导数的影响，绘制了影响因素的敏感性曲线，并对早期及晚期的结果进行近似，为试井分析提供了理论基础。

| Abstract: | Unsteady flow of double porosity medium was studied in this paper and a new analytic solution in Laplace space was developed for infinite conductivity vertical fractures. Several influential factors including transmissihility coefficient, storability, and boundary, which would affect the plotted curves of bottom-hole pressure and pressure derivation to some extent, were analyzed in this paper. In addition, approximate solutions of early period regime and later time regime were presented, which would he used to equip well test analysis of double porosity medium with corresponding theory. |
