化学驱油是现代EOR重要技术之一。传统“测-注-测”技术和实验室岩心驱替分析是评价储层剩余油饱和度和驱油效率的2种常用方法。传统的“测-注-测”整个驱替测试过程需要几周时间才能完成。用传统技术注入的驱替剂达到离井眼约3m远的产层段,不仅要求大剂量、长时间的注入过程,而且还要配备用于混合、处理驱 Chemical flooding is one of the important technologies of modern EOR. Traditional “test-injection-test” techniques and laboratory core-flooding analysis are two common methods for assessing reservoir residual oil saturation and flooding efficiency. The traditional “test - note - test” the entire displacement test process takes a few weeks to complete. The flooding agent injected with the traditional technology reaches the pay zone about 3m away from the wellbore, which not only requires high-dose and long-time injection but also is equipped with a mechanism for mixing, treating flooding
