The minimal value of porosity is around 2.5% though throatradius method and porosity-water saturation method.
运用喉道半径法、孔隙度-含水饱和度法求得孔隙度下限值为2.5%。

The experimental data show that the pore structures (the ratio between porosity and permeability) are consistent with the pore throatradius.
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 results show that the sandstone rock of the area has three internal pore structure, reservoir rock pore complex structure, pore throatradius relatively large variation range.
