油田含聚污水处理与利用方法探讨

Discussion on treatment and utilization of polymer containing wastewater in Oilfield

目前我国已经进入了三元复合驱动的三次采油阶段,在该阶段聚合物驱油技术在我国大量应用,聚合物驱油技术有效的为油藏补充了驱动能量,提升了原油的综合采收率,但也带来了新的问题注聚产生的污水,处理相对困难,给周边生态环境带来了严重威胁。课题研究由此出发,深入分析含聚合物污水的特点,结合国内外研究现状,提出相应的污水处理方案。

At present,China has entered the stage of tertiary oil recovery driven by ASP.At this stage,polymer flooding technology is widely used in China.Polymer flooding technology effectively supplements driving energy for the reservoir and improves the comprehensive recovery of crude oil,but it also brings new problems.The sewage produced by polymer injection is relatively difficult to treat,It poses a serious threat to the surrounding ecological environment.Based on this,the characteristics of polymer containing sewage are deeply analyzed,and the corresponding sewage treatment scheme is put forward in combination with the research status at home and abroad.
