| 摘 要： | 将实际的垂直裂缝井简化成裂缝高度小于地层有效厚度的矩形，在此基础上采用乘积解给出渗流时的地层压力及井底瞬时压力，使用Laplace变换给出考虑井筒存储及表皮系数的部分压开垂直裂缝井在Laplace空间上的井底压力解，并通过Laplace数值反演给出考虑井筒存储及表皮系数的部分压开垂直裂缝井无量纲压力及导数，最后，通过一个应用实例介绍部分压开垂直裂缝井试井分析方法。 |

| Abstract: | This paper simplifies actual vertical fracture well into rectangle and it's height is less than formation thickness.The dimensionless pressure distribution and transient pressure in wellbore are obtained through using product of Green function.The dimensionless transient pressure with dimensionless storage constant and skin are obtained by means of using Laplace transform in Laplace space.The dimensionless pressure and it's derivative of partial open vertical fracture with dimensionless storage constant and skin are obtained by numerrical inversion of Laplace transforms.Finial a actual example is used to illustrate the method of well testing analysis for partial open vertical fracture. |
