Pore radius, pore density and pore -throat ratio influence reservoir permeability to different extents.
孔隙半径、孔隙密度和孔喉比对地层渗透率均产生影响。
The experimental data show that the pore structures (the ratio between porosity and permeability) are consistent with the pore throat radius.
实验研究表明，孔隙结构(渗透率与孔隙度的比值)与孔喉半径有良好的相关性。
The effects of pore-throat ratio, coordination number and shape factor on relative permeability were investigated in a water-wet condition by means of microscopic si.
