聚合物采油在西峰油田的实验技术研究

Experimental Technology Study of Ploymer Flooding in Xifeng Oilfield

聚合物采油是通过向地层注入聚合物,这种驱油方式可提高原油的产量和采油率。本文通过实验分析,研究了聚合物驱油在西峰油田的开采规律,同时提出了提高聚合物驱油效率的方法。实验研究的结果表明,高浓度聚合物的注入时机、注入浓度以及注入速度都直接影响着油田的采收率。

Polymer flooding is to inject polymer into the formation, the oil displacement mode can increase the crude oil production and oil recovery rate. In this paper, the pattern of the polymer flooding in Xifeng oilfield exploitation was studied, and a method to improve the efficiency of polymer flooding was proposed. The experimental results show that, injection timing, injection concentration and injection rate of high concentration polymer have direct effect on the oil efficiency.
