high permeable strata 高渗透层
low permeable strata 低渗透层
the extra-high permeable strata 特高渗透层
The water intake capacity of the intermediate and low permeable strata increasing and the water intake capacity of the high permeable strata reducing are marked by the permeability grade increasing.
渗透率级差越大，低渗透层相对吸水量提高，高渗透层相对吸水量降低幅度越大，调剖效果越显著。
