The better the pore structure of reservoir, the higher the tested productivity and the critical water saturation, the lower the correspondent cutoff of effective porosity.
储层孔隙结构越好，测试产能越高，临界水饱和度越高，其对应的有效孔隙度下限越低。

Increasing the effective inductance makes it easy to control the cutoff frequency characteristics of the DGS planar circuits.
