随着我国石油工业的迅速发展,水溶性聚合物已广泛地应用于采油工业的各个方面,随着聚合物驱溶液的注入,使采出水中因含有聚合物而粘度高,水中油滴及固体悬浮物的乳化稳定性强,进而导致油、水分离和含油污水处理的难度,加大利用水驱常规污水处理工艺处理含聚污水难以达到回注原地层的水质要求,所以需要大量低矿化度的清水用来配制聚合物驱溶液,从而也使原注水-污水系统平衡被破坏。因此,含聚污水的处理已经成为油田含油污水处理的重要课题之一。
With the rapid development of China’s oil industry, water-soluble polymers have been widely used in all aspects of the oil recovery industry. With the injection of polymer flooding solution, the viscosity of the produced water due to the presence of the polymer is high. Oil droplets and solids Suspension emulsion stability, and thus lead to the oil, water separation and oily wastewater treatment difficulty, increase the use of water treatment conventional sewage treatment process containing poly sewage is difficult to re-injection of the original formation of water quality requirements, it requires a lot of low mineralization Degree of water used to formulate polymer flooding solution, which also makes the original water injection - sewage system balance is destroyed. Therefore, the treatment of polluted water has become one of the important topics in oily wastewater treatment.
