Process and technology of produced water treatment in Daqing oilfield

Based on the treatment processes for produced water from late period of high water cut stage of oilfield, low permeability produced water, polymer flooding produced water and ASP flooding produced water, the current status and existing problems of produced water treatment processes were elaborated, and then, many technical measures such as increasing settlement separation efficiency, improving filtration efficiency, perfecting backwashing efficiency and so on were proposed, so as to reach the aim of improving the efficiency of existing oilfield produced water treatment facilities and meeting the requirement of petroleum reservoir exploitation production.
