Abstract: 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 explained in physics and mechanics by means of boundary layer theory. Finally, the effect of the different flow performances on developing an oilfeld is analyzed. This study is of some significance for guiding an oilfeld development.
