摘　　要：聚合物驱作为三次采油的重要技术之一,已在多个油田规模化应用。但在该类采出水破乳、絮凝、分离过程中,聚丙烯酰胺转移进入固相,形成了稳定性高、处理难度大的含聚污泥,给污水处理系统带来了严重的污染负荷,同时也造成聚丙烯酰胺大量浪费。通过含聚污泥的产生机制,归纳总结了现有采出水破乳分离工艺存在的问题,指出了水固同治是“双碳”背景下含聚采出水绿色低碳处理及资源化的方向。As one of the important technologies for tertiary oil recovery,polymer flooding technology has been applied on a large scale in many oil fields.This type of produced water undergoes demulsification,flocculation,and separation processes,causing polyacrylamide to settle into the solid phase.The resulting polymer-containing sludge has high stability and is difficult to handle.This not only brings a serious pollution load to the sewage treatment system,but also causes a large amount of waste of polyacrylamide.This paper summarized the existing problems in the current produced water emulsification and separation process through the generation mechanism of polymer-containing sludge.It was pointed out that“water-solid co-management”was the research direction for green,low-carbon treatment and resource utilization of polymer-containing produced water under the“dual-carbon”background.
