以某油田废水处理及回注工程为例，论述废水治理设施与工艺，研究油田开发过程中运行负荷变化对污水处理系统的影响，使油田废水处理设计更加灵活。通过合理使用化学试剂，解决了影响水质的腐蚀、堵塞和结垢3大问题。
Taking an oilfield wastewater treatment and reinjection project as an example, the paper discusses the wastewater treatment facilities and technology, studies the influence of the operating load change on the wastewater treatment system in the process of oilfield development, and makes the design of the oilfield wastewater treatment more flexible. Through the rational use of chemical reagents to solve the impact of water quality corrosion, plugging and scaling three major issues.
