Low permeating and porous medium was taken as an object for study, it can be educed from the experiment that the curve of permeability changed with the effective pressure.
以低渗透多孔介质为研究对象，通过实验得出渗透率随有效压力变化曲线。
The variation of medium pore diameter and porosity factor is in accordance with that of the pore volume, showing a high permeability of low rank coal reservoirs.
中值孔径、孔隙率的变化特征与孔容一致，预示了低煤级煤储层较高的基岩渗透率。
The reservoirs of the medium rank coal characterize low gas content, low gas saturation, good permeability, and high energy in Hedong area of Shanxi, China.
中国山西河东地区中阶煤储层的含气量比较低、含气饱和度低，而储层渗透性好，储层能量比较大；
