摘要
开发底水油藏水平井最大的问题就是底水脊进。底水脊进现象的存在制约了水平井的有效开发。该文利用镜像反映和势的叠加原理,给出底水油藏水平井稳定渗流情况下不同时刻和临界条件下底水脊进高度和水脊面距井轴的侧向距离的解析解,同时结合矿场实例给出实际优化水平井最佳井筒位置,其结果和方法对底水油藏水平井油藏工程设计和理论研究具有一定的指导意义。
The biggest problem for a horizontal well in bottom-water reservoir is water cresting, which restricts the hori- zontal well to be developed effectively. By means of image theory and potential superposition principle, this paper presents the analytic solution of water cresting height and lateral distance from wellbore under steady flow, and optimizes the optimum wellbore placement. The results and the method are useful for reservoir engineering design and the theoretical research for horizontal well.
