| 摘 要： | 在分析分段完井渗流机理的基础上,根据质量守恒原理及动量定理推导出了水平井分段完井井筒压降计算模型,并引入了一个修正的壁面摩擦系数,可以准确计算分段后各微元段的压降.针对底水油藏类型,根据势的叠加原理导出了单相原油三维稳态渗流的压力分布公式,再结合分段压降模型,建立了油藏渗流与井筒流动耦合产能预测模型.实例计算表明:用此...

| Abstract: | This paper deduced a pressure drop calculation model based on the analysis of the percolation mechanism and the principle of conservation of mass and momentum theorem.It also introduced a modified skin friction coefficient to calculate accurately the pressure drop of each infinitesimal section after partition.In addition,it deduced the three-dimensional steady-state seepage potential distribution and stress distribution formula according to the type of the bottom-water drive reservoir and the potential of s... |
