| 摘 要： | 在数值模拟结果分析的基础上，半压裂直井近似为一条垂直裂缝。采用拟三维的思想及保角变换方法，推导出垂直裂缝的产能公式，并将本文公式的计算结果与Ｊｏｓｈｉ、Ｃｉｇｅｒ、Ｇｕｏ以及数值结果进行对比。本文公式可满足压裂直井产能估算的要求。

| Abstract: | Based on the results of reservoir simulation, fractured vertical well can be approximately regarded as a corresponding fracture. The productivity of fractured vertical well is derived through pseudo-3D and conformal transformation. And also, results of different productivity formulas are compared with that of reservoir numerical simulation. The comparison indicates that the productivity formula presented in this paper can be used to estimate the productivity of fractured vertical well. |
