大庆油田回注水水质劣化原因分析

摘要

大庆油田回注水从联合站到注水井工段发生水质劣化现象，造成回注水水质不达标，给油田污水回注带来了极大不便。针对以上问题，以大庆油田的回注水作为研究对象开展实验，分析和研究联合站到注水井水质劣化因素，提出相应的处理措施，从而改善回注水水质。%Daqing oil field reinjection water from joint station to the injection wells section was showed signs of deterioration, result-ing in injection water quality was not up to standard. This phenomenon had brought great inconvenience to the reinjection of oilfield sewage. To solve theabove problem, we choosed Daqing oil field reinjection water as research object to carry out the experiment, analyzed and found out the water quality degradation factors, put forward the corresponding measures, so as to improve reinjection water quality.
