摘要：
Produced water from polymer flooding was much more difficult to be treated than that from water flooding. The mechanisms of polymer stabilizing the oil-in-water emulsion were the decreases of interfacial tension and electric conductivity, and the increases of zeta potential and bulk phase viscosity. Inorganic flocculant, the combination of inorganic flocculant and polymer degradation agent, and the combination organic flocculant and coagulant were used to break the oil-in-water emulsion stabilized with polymer. It was the most effective way to use the combination of organic flocculant and coagulant for treating polymer stabilizing oil-in-water emulsion.
