摘要
本文是应用保角变换方法和势函数理论推导出底水驱油藏水平井产能公式、比采油指数公式。在推导过程中,考虑了油藏顶部封闭边界、恒压边界、油藏各向异性以及水平井在油藏中位置等因素对水平井势分布的影响,推导出底水驱油藏势分布函数。在此基础上得到的产能公式,经试算结果比较,更加符合实际。
In this paper, the conformal transforms and potential function theory are applied to derive productivity, specific productivity index of a horizontal well. In the process of derivation, factors, such as impermeable boundary on the top of reservoir, equal pressure interface, anistropy of reservoir and position of horizontal well in the reservoir, which have influence on the potential distribution in bottomwater drive reservoir, are considered. On the basis of potential distribution function, the productivity formula is derived. After comparing the calculation results, the productivity formula in this paper conforms to the actual situation satisfactorily.
