| 摘 要： | 系统分析了南三区东部聚合物驱产出水处理前后原油、聚合物、固体悬浮物、无机离子和细菌等成分的含量及其固体悬浮物颗粒直径大小与分布 ,并且对该区聚合物驱产出水主要特征进行了总结。在此基础上 ,根据油层损害机理并且结合该区油层的孔渗特征 ,研究和确定了污染物质。研究结果认为 :常规处理方法对污水中原油处理效果最好 ,而对PAM和固体悬浮物处理不太理想。

| Abstract: | The contents of oil,polymers,suspended solids,inorganic ions and bacteria in water with or without pretreatment were analyzed respectively,which was produced from formation with PAM flooding in Nansan Area,Daqing Oilfield.The diameter and distribution of solids were also measured by laser granularity equipment.According to the chemical and physical properties of these materials and their damage mechanism to oil formation,the contaminant were determined.The sulphate deoxidized bacteria are the main contaminant for the rejecting of water into formation.The suspended solids and oil can damage formation with medium or low permeability,and PAM can damage formation with low permeability.The usual pretreatment of water can remove oil significantly,but have little effects on removal of PAM and particles. |
