Stability and Chemical Treatment of Daqing Oilfield ASP Flooding Produced Liquid

The influence of residual alkali,surfactant and polymer on the stability of ASP (alkali,surfactant and polymer) flooding produced water was studied on artificial ASP flooding produced water.Using artificial ASP flooding produced water a reverse emulsion demulsifier was developed for ASP produced water treatment.The oil water separation performance of the reverse emulsion demulsifier was tested on both artificial ASP produced water and oilfield ASP produced water.
