针对大港油田的回注水 ,利用数理统计方法 ,介绍了一种新型油田注水用杀菌剂SJ - 10的研究、作用性能及杀菌机理 ,并讨论了pH值及温度对其杀菌性能的影响。实验证明 ,该杀菌剂能有效控制和抑灭回注水中的细菌 ,其杀菌效率优于油田常规用杀菌剂 12 2 7,具有杀菌效果好、适应性强、低毒、使用方便、价格低等特点 ,是一种新型有效的杀菌剂。
Aiming at the injection water of Dagang Oilfield, a new type of oilfield disinfectant SJ - 10 for oilfield injection was introduced by mathematical statistics. The effects of pH value and temperature on its bactericidal performance were discussed. The experiment proves that the bactericide can effectively control and repress bacteria in the water injected back to the bactericidal water, and the bactericidal efficiency is better than that of the bactericide 1227 in the oilfield, which has the advantages of good bactericidal effect, strong adaptability, low toxicity, convenient use and low price Features, is a new and effective fungicide.
