Flocculants for Produced Water from Polymer Flooding in Daqing Oilfield
HPAM with MW of 3×106 was found suitable to simulate the composition of the formation water in Daqing Oilfield. PAC, CPAM and ZTP were used for treating the produced water from polymer flooding in Daqing Oilfield. The micro structures of the suspended materials in produced water were observed with particle imager and SEM. The results show that ZTP removed HPAM efficiently, and that both PAC and CPAM produced many aggregates.
