聚合物驱油防窜剂的合成及防窜效果评价

THE SYNTHESIS AND EVALUATION OF FLEEING PROOF REAGENT OF POLYMER FLOODING

以多乙烯多胺、环氧氯丙烷、三甲胺等为原料合成出一种新的防窜剂 ,确定了最佳合成条件 ;进行了岩芯防窜效果评价 ,结果表明 ,可使岩心高渗透层的阻力系数上升 ,高低渗透层的流量比下降 ,聚合物产出时间变长 ,采收率提高 6.5%。

A novel fleeing proof reagent was synthesized with polythylenepolyamine, epoxychoropropane and trimethylamine. Optimized synthesis conditions were determined, and fleeing proof effect in rock core was evaluated. The synthesized fleeing proof reagent showed the following advantages: it makes the resistance coefficent in high permeating layer increased, the ratio of flow rates of high permeating and lower permeating layers decreased, and the polymer lasting time prolonged. The total oil yield was increased by 6.5%.
