摘要
方法 应用保角变换原理和局部渗流阻力的概念 ,将多分枝水平井渗流问题转变为平面径向渗流问题 ,从而简化了求解过程。目的 改善低渗透油田或裂缝性油田的开发效果。结果 与文献上已发表的稳态产能公式相比 ,吻合程度相当好。结论 多分枝水平井可大大沟通井筒与低渗透油藏的接触面积 ,增加产能 ;如能沟通天然裂缝 。
Method\ Percolation of multiple-hole horizontal well is exchanged to radial percolation by applying conformal transformation theory and local percolation restriction. In this way to simplify the solution finding process. Purpose\ To improve the development effect of low permeability oilfield or fractured oilfield. Result\ It matches well enough with literature publicized stable productivity equations. Conclusion\ Multiple-hole horizontal well can significantly improve contact area between wellbore and low permeability reservoir, increase productivity as well. Meanwhile, it will also achieve better development effect of fractured reservoir if in-situ fractures can be linked. \;
