摘要
在中低渗、高温高盐、普通稠油油藏条件下,开展了聚合物驱提高采收率物理模拟实验研究。物理模拟实验研究了聚合物体系的注入性以及驱油效果,实验结果表明,由污水配制的浓度为2500mg/L、3000mg/L的聚合物溶液能够注入到渗透率60×10-3μm2以上的岩心中,聚合物驱较水驱提高采收率18.75个百分点。
In this paper,it carried out the study of polymer flooding to improve oil recovery of physical simulation experiment.The experiments studied the injection and oil displacement effect of polymer system.The experimental results show that the prepared polymer solution by sewage with the concentration of 2500mg/L、3000mg/L can be injected into the core with the permeability over 60×10-3μm2.The recovery of polymer flooding is 18.75% higher than water flooding.
