1) oil plugging rate
堵油率
1.

2.
The selective water plugging agent of cation polyacrylamide is chosen, the core simulation experiment show that, for the cores with different permeability, the water plugging rate is greater than 85% and the oil plugging rate is about 20%.
岩心模拟实验表明,对于不同渗透率的岩心,该堵剂的堵水率大于85%,堵油率在20%左右,具有良好的选择性;通过实验,对岩心的选堵机理进行了分析,选堵剂在岩心内的吸附与滞留是引起岩心渗透率下降的主要原因;水基选堵剂凝胶液优先进入含水的通道,在含水的通道内形成凝胶,从而堵塞岩心的孔道,因此多孔介质中油水通道的分离在渗透率下降不均等中起主要作用。
