随着胜利油田的不断开发,其产出液平均综合含水率超过90%,污水的处理量大幅增加,污水类型复杂多样,对污水处理设备以及技术提出更高要求。油田污水的含油量高、水量较大,并且含有菌类、锰、铁、有机物等对回注造成影响的污染物质,因此造成油田污水处理较为困难。本文对胜利油田污水特性与回注水质的要求进行阐述,对其污水处理技术包括污水含油量的控制、污水处理的新技术等进行分析研究。
With the continuous development of Shengli Oilfield, the average integrated moisture content of the output liquid exceeds 90%, the volume of sewage treatment increases greatly, the types of sewage are complex and diverse, and higher requirements are set for the sewage treatment equipment and technology. Oilfield sewage containing high oil content, large amount of water, and contains fungi, manganese, iron, organic matter and other effects on the injection of pollutants, resulting in oilfield wastewater treatment is more difficult. This paper elaborates the sewage characteristics and the quality of reinjection water in Shengli Oilfield, and analyzes and researches the sewage treatment technology including the control of the oil content of sewage and the new technology of sewage treatment.
