中原油田注水系统控制SRB和硫离子技术研究

Study on Controlling SRB and Sulfur Ion Technology of Water Injection System of Zhongyuan Oilfield

实验研究了注水系统控制SRB和硫离子的技术。结果表明:氧化剂投加浓度达到30mg/L时,来水中的SRB基本除去;SRB在pH值为6.0～8.0比较活跃,7.0～8.0最适宜生长,9.0以上SRB生长受到抑制;pH值在6.0～8.0时硫离子的含量降低不明显,在36h后降低70%以内,而pH在9.0～10.0时72h后降低85%以上;随pH的增加含硫量降低,在9.0～10.0时降低比较显著。

he paper studied a kind of controlling SRB and sulfur ion technology in water injection system. The results showed that： the oxidant dosage will be able kill all SRB in sewage when its concentration is 30mg/1; SRB is more active in pH 6 - 8,and the most suitably grows in pH 7 8, but growth of SRB is inhibited in pH 9; pH value in 6 - 8 sulfur ion content is decreased obviously, after 36h reduced less than 70%, and pH in 9 - 10 lower than 85% after72h; with the increasing of pH sulfur content is obviously reduced in pH 9 - 10.
