大庆油田三元复合驱随着采出液中聚合物浓度升高、粘度增大,导致油水处理困难。针对这一问题,本文探讨了提高温度、曝氧、超声波,H2O2溶液氧化及微生物降解的不同方法进行三元采出液降粘处理。通过对比分析,得出目前提高温度是降粘的最佳处理方法,同时可以提高破乳效果。 Daqing Oilfield ASP flooding with the production of polymer concentration increases, the viscosity increases, resulting in oil-water treatment difficulties. In response to this problem, this paper explores different ways to increase the temperature, oxygen exposure, ultrasonic, H2O2 oxidation and microbial degradation of the ternary production fluid viscosity reduction treatment. Through comparative analysis, it is concluded that the current temperature increase is the best treatment for viscosity reduction, and the demulsification effect can be improved at the same time.
