The factors that influence core flow efficiency are flowpermeability decrease in crushed zone and the thickness of crushed zone.
流动效率影响因素依次为：压实带中渗透率下降程度、压实带厚度。
2
The ability of water, or other fluids, to flow through the interconnected pore spaces in rocks is termed permeability.
水或其他流体通过岩石中相互连通的孔隙空间的能力称为渗透率。
3
Flow is then stopped, and if the formation has sufficient permeability, the formation will flow to equilibrate the tester with the bulk of the formation.
