摘要
油田采油污水组分复杂,极易乳化,且乳化体系稳定,油水分离难度较大。针对油田聚驱采油污水、复合驱采油污水水质复杂、油水分离困难、回注水含油量不达标的问题,传统技术多采用单元叠加工艺,造成流程冗长、能耗大,开发适用的高效破乳剂是石油环保领域的难点及热点。
Oilfield produced water has the properties of complex composition, easy emulsification, stable emulsified system, and difficult oil-water separation. Typical treatment technology for waste water produced by oilfield polymer flooding and ASP flooding process is to combine multiple treating units. But the technology has long process flow and large energy consumption, and development of high efficient demulsifier is very difficult.
