低分子阳离子聚合物对高浓度聚驱解堵作用的评价

Evaluation of the Removing Blockage Effeciency for High Concentration of Polymer Flooding by Low Molecular Weight Cationic Polymer

针对大庆油田的现状,研制出了一种低分子阳离子聚合物,能够有效改善地层堵塞状况,解堵率达到90%以上。

In this paper,based on the present situation of Daqing Oilfield,a kind of low molecular weight cationic polymer was synthesized,which could decrease the formation of plugging effectively,and the removing rate of blockage was more than 90%.
