实验得出该体系对于水的封堵率可达到90%以上，而对于油的封堵率仅为30%左右，具有较强的选择性封堵能力。
The experiments showed that the block rate of water could reach over 90%. on the other hand, the block rate of oil was less 30%, which demonstrated excellent plugging ability.
结果表明，该堵剂可使水相渗透率下降85%以上，油相渗透率下降25%以下，具有明显的选择性封堵作用及优良的耐冲刷性。
The results showed that, the permeability of water phase decreased 85% at least, the permeability of oil decreased no more than 25%. PDZ-1 has high selective plugging and a nice flushing resistance.
岩心流动实验和对弱凝胶在孔隙中运移行为的研究表明，该调驱剂封堵率高，具有良好的选择性，剖面改善效果好。
The results of core flooding experiment and the study of the propagation about the weak gel show that the agent has a high blocking rate and good selection which can modify the water profile well.
