摘要
将分枝水平井视为垂直裂缝 ,在均匀流量假设下 ,利用复变函数理论推导出了当分枝数分别为 1和 2时的分枝水平井产能公式。证明了在均匀流量假设下垂直裂缝相当的折算半径与导流能力为无限大的相比减少 12 %。
The productivity formula of horizontal well, which is based on the assumption of uniform flux as well as considering the branch horizontal well to be a vertical fracture, has been deduced by using the complex function theory when the number of branch is 1 or 2 respectively. In accordance with the supposition of uniform flux, this paper proves that the conversation radius of vertical fracture is 12% less than that of the infinite conductivity.
