Abstract

Abstract: Treating and reinjecting the wastewater of oilfield is a correct way to develop and use water resources at present. A novel-type humic cationic polymer was synthesized using humic acid (HA), dimethylamine (DMA), and epichlorohydrin (ECH) by aqueous solution polymerization. The optimal reaction conditions were determined. The reaction temperature was 65°C, the reaction time was 6.0 h, m (HA): m (ECH): m (DMA) = 1.0:13.9:15.0. The oil removal efficiency and viscosity reduction effects were investigated using the polymer-flooding wastewater of Daqing oilfield. The results showed that humic cationic polymer had good effect on viscosity reduction, polymer removal, and oil removal of the polymer-flooding wastewater. The wastewater after being treated can provide as reinjection water for chemical flooding, which also improve the utilization of the wastewater.
