在油田油井基础数据和作业数据统计分析的基础上，采集目标区块若干油井、污水处理站和注水井样品10个，进行水质分析和微生物种群数量测定，探讨了长期加药杀菌对目标区块的影响，并探索性地进行反硝化抑制室内实验，结果表明：传统的化学杀菌方法指标不治本，现有杀菌剂只能在短距离范围内起作用，大量投加杀菌剂使得硫酸盐还原菌（SRB）产生抗药性，总磷本底值的大幅提高促进了微生物的生长，杀菌剂杀菌效果不明显，反硝化抑制的生物防治方法将是油田 SRB 防治的理想方法之一。

On the basis of statistical analysis of oil well data,10 samples were collected from several oil wells,sewage treatment station and injection wells of the target area.The water quality and microbial populations of these 10 samples were determined to investigate effects of long -term dosing sterilization on target aerea,and the denitrification inhibition in-door experiments were tested.The results showed that traditional indicators of chemical sterilization method was not a cure, the bactericides could only play a role in the short distance range,and extensive use of the bactericides could result in sul-fate reducing bacteria (SRB)became resistance and bactericidal effect was not obvious.Therefore,denitrification inhibi-tion of biological control method is an ideal method of oilfield SRB prevention.
