摘要
总结了油田采出水的特性及现场采用的水处理工艺流程 ,比较不同处理方法的适用范围及优缺点。指出目前油田现场采出水处理存在的问题 ,特别是对大庆油田聚合物驱和三元复合驱采出水进行了深入分析 ,阐明了污水处理难度大的原因是聚合物增加污水粘度 ,表面活性剂使污水严重乳化 。
The article summarizes the speciality of oilfield produced water and wastewater treatment craft flow in oilfields and compares applied scopes,advantages and disadvantages of different treatment methods. It also points out problems of oilfield produced water in oilfields,and especially analyzes the produced water of polymer flooding and three compounds flooding in Daqing Oilfeld. The causes for the difficulties treatment are that the polymer increases wastewater's viscodity and surfactant strengthen emulsification,and at the end the article points out the effective approaches to this wastewater treatment.
