pore and throat radius

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 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。
