油田开采中后期,采出水量越来越多,污水处理与回收再利用成为一项重要工作。海一联合站主要担负海外河油田原油污水处理任务。近年来,采油区在对油井采用工艺措施时,大量使用化学药剂,当这些油、水、药剂混合液进入联合站以后,会引起站内原油脱水、污水处理环节的指标波动。一、污水水质现状海一联合站对污水水质采取分段控制分段达
In the middle and late stages of oilfield exploitation, the amount of water produced is increasing. Sewage treatment and recycling have become an important task. Sea-United station mainly responsible for oversea river oil crude oil wastewater treatment tasks. In recent years, the oil production area has used a large amount of chemical agents when using process measures for oil wells. When these oil, water and pharmaceutical liquid mixtures enter the joint station, the crude oil in the station will be dewatered and the indexes of the sewage treatment will fluctuate. First, the status quo of sewage water sea a joint station on the sewage water quality control to take sub-paragraph up
