摘　　要：通过对油田已建在用采出含油污水处理站的处理效果的评价,以及试验研究,确定了适合聚驱(包括高浓度)和三元复合驱采出含油污水处理的工艺技术,以"化学方法为主,物理方法为辅"阶段发展到以"物理方法为主,化学方法为辅"的创新性处理阶段。能够满足油田开发生产的需要,确保三次采油各种驱油地面配套采出水达到Q/SYDQ 0605—2006《大庆油田油藏水驱注水水质指标及分析方法》的要求而回注,减轻了环境污染。According to the evaluation on the treatment effects of the produced water from oilfield,a technology suit for polymer flooding produced water and three compound flooding produced water was determined,which is mainly by physical method and chemical method as supplement.This technology can meet the requirements of oilfield production and ensure the produced water from tertiary oil recovery to meet the reinjection requirements in the standard of 'Indexes and Analytical Method of Injected Water Quality in Reservoir Water Flooding in Daqing Oil Field'(Q/SYDQ 0605-2006),which avoids environmental pollution.
