油田回注水处理工艺研究

Study on the treatment technology of oilfield injection water

文章通过对吐哈油田回注水水质特点进行分析,并针对原水弱酸条件和矿化度高、含铁高的特点,结合现有的回注水处理工艺,重点进行了混凝试验研究,筛选出了合适的处理剂,对其工艺条件进行了优化,在优化出的最佳工艺条件下,水质主要指标SS、总铁含量满足注水水质要求。

Through the analysis of the water quality charateristics of the injection water of Turpan-Hami Oilfield,against the weak-acid condition of raw water and the characteristics of high salinity and high iron,combined with present treatment technology of injection water,this paper emphatically analyzes coagulation test,screens out suitable treating agent,and optimizes it＇s technological condition.Under the optimum conditions,the main water quality index——SS and total iron content meet the water quality requirement of injection.
