1·The minimal value of porosity is around 2.5% though throat radius 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%。

2·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。

3·The results show that the sandstone rock of the area has three internal pore structure, reservoir rock pore complex structure, pore throat radius relatively large variation range.

研究结果表明本区砂岩岩样内部表现为三套孔隙结构，储集岩的孔隙结构复杂，孔隙半径变化比较大。

4·The lower the permeability and the smaller the pore-throat radius as well as the lower the reservoir pressure, the easier the formation of water locking damage, and it is difficult to be removed.

渗透率越低，孔喉半径越小，油层压力越低，越容易产生水锁损害，且越难以解除其损害。

5·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。
