The waterintakecapacity of the intermediate and low permeable strata increasing and the waterintakecapacity 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。
2
The main characteristics of low permeability reservoir are small reservoir pore, fine throat, high seepage resistance and low waterintakecapacity.
低渗油藏的主要特征是具有小孔隙、细喉道、高渗流阻力和低吸水能力。
3
Deliverability and waterintakecapacity of oil well are very low.
