研究了炼油厂废水与油田产出污水混合处理为油田回注水的工艺，并进行了工业性试验。结果表明，处理后的水质符合部标ＳＹ５３２９—８８标准，解决了炼油厂废水外排污染环境的问题，同时，拓宽了油田注水水源，具有投资小，处理费用低等优点。 The process of mixing wastewater from oil refinery wastewater and oilfield effluent into oilfield injection water was studied and industrial experiments were carried out. The results show that the treated water meets the standard SY5329-88, which solves the problem of external pollution of refinery waste water. At the same time, it broadens the water injection source of oilfield and has the advantages of small investment and low processing cost.
