摘要：
本文介绍了用气浮——过滤法处理采油污水的试验情况。试验证明该方法具有处理效果好、适应能力强、处理后回注对地层伤害程度小的优点。这对我国油田注入含油污水的工作具有-定的参考价值。

Abstract:
This paper suggests a new method of treating sewage in oil production, discusses several factors influencing dissolved—gas flotation. Experiments show that dissolved—gas flotatin gs a better method for treating sewage than coagulation. This treatment can decrease the amount of oil, SS and increase MF significantly, Further treatment by filtration gives clear water with MF>20,SS<3.4 mg/l, oil<3.0 mg/l. So the treated water can be reinjected into the formation and it causes less permeability decrease than that treated by the present method.
Key words: Sewage treatment, Dissolved-gasflotation, Filtration, Formation damage
