摘要
分析了井底聚合物返出物成分 ;通过物理模拟实验 ,给出了注聚体积、聚合物滞留量对不同渗透率岩心的伤害程度 ,确定了速敏程度及其伤害半径 .
The element of drainage matter from the bottom of polymer injection well was analyzed. Damage of polymer injected volume and polymer retention level on formation with different permeability was determined by core simulation test, also velocity sensitivity and damage radius were obtained. This technique provides theoretic basis for plug prevention and removal in polymer injection wells.
