Progress in the Development and Application of Oilfield Produced Water Treatment Processes

A large number of oilfield produced water is produced during the developing of oilfield，the optimal way to process these oilfield produced water is to reinject it into strata. This paper firstly analyzes the characteristics of oilfield produced water, then focuses on introducing the research and application process of both traditional and new treatment technologies of produced water , and finally brings forward some expectation about the application and development direction of the oilfield produced water treatment processes.
