摘要
运用无因次分析法对岩心渗流实验数据进行了分析和研究，按雷诺数由小到大依次分为三段：超低速区、低速区及达西流区，并给出各段的数学表达式。综合应用边界层等理论给出这些特殊渗流现象的物理和力学解释。最后分析出不同渗流运动形态对油田开发过程的影响。其研究的结果对于油田的开发具有一定指导意义。
The study and analysis of flow experimenting core data are made by using dimentionless analysis method, providing three flow sections (extra low velocity flow section, low flow section and Darcy flow section) by Reynolds number in order as well as the math expressions for each section. These special flow phenomena have been ex-plained in physics and mechanics by means of boundal layer theory. Finally, the effect of the different flow perfor-mances on developing an oilfield is analyzed. This study is of some significance for guiding an oilfield development.
