摘　　要：对中国石化胜利油田(简称胜利油田)二元复合驱采出液进行了分析,并用分子模拟方法考察了聚合物、石油磺酸盐和助表面活性剂在油水界面的状态。实验室合成了阳离子聚合物净水剂,并在胜利油田孤东采油厂东一联污水处理站进行了现场工业试验,结果表明,试验期间一次沉降罐污水中油质量浓度从试验前的1900 mg L降至1050~1250 mg L,外输污水含油量合格,达到了预期的效果。The produced fluid of binary complex flooding in Shengli Oilfield of SINOPEC was analyzed,and the state of polymer,petroleum sulfonate and surfactant at oil-water interface was investigated by molecular simulation method.The cationic polymer water purification agent was developed in laboratory and tested in Dongyi union station in Gudong oil production plant in Shengli Oilfield.The result showed that the oil content in the 1 st settling tank decreased from 1900 mg L to 1050—1250 mg L,the oil content of external sewage was qualified,and the expected effect was achieved.
