将水质改性剂与Ｏ／Ｗ型破乳剂结合使用，在室内筛选了新疆油田采油一厂稀油处理站产出污水的水质改性配方，优选水质改性处理配方４０余个，处理剂近２０种，确定了４种水质改性处理方案，筛选结果表明：（１）可将稀油站污水处理为合格的注入水；（２）处理后的水其水质指标达到ＳＹ／Ｔ５３２９－９４标准；（３）处理工艺简单，药品品种少，流程改动少 The water quality modifier and O / W demulsifier used in combination with the indoor screening of Xinjiang Oilfield Oil Production Plant dilute oil treatment station output of sewage water quality modified formulations, preferably water quality modification of more than 40 formulations, the treatment agent near 20 species and 4 water quality modification schemes were determined. The results of the screening showed that: (1) the wastewater from the lean oil station can be treated as qualified injection water; (2) the water quality of the treated water has reached the standard of SY / T5329-94 ; (3) treatment process is simple, less drug varieties, process changes less
