| 摘 要： | 主要研究温度对硫酸盐还原菌(SRB)生长的影响和SRB对油田套管的腐蚀作用,着重分析温度、Fe2+浓度对碳钢SRB腐蚀的影响.实验表明,在37℃时SRB的活性最强,对碳钢促进腐蚀,介质中Fe2+对碳钢SRB腐蚀影响还与温度有关:37℃时加速SRB腐蚀,60℃时则相反,这与腐蚀产物生成不同的硫化物有关.实验结果与中原油田文10-1井套管内腐蚀上部严重下部轻微一致.

| Abstract: | The influence of the temperature on the growing of sulfate-reducing bacteria (SRB) and the effection of SRB on corrosion of sheath-tube in oil field are studied in this paper. The influences of temperature and the concentration of Fe2+ on the corrosion of carbon steel induced by SRB are analysed emphatically. Experiment shows that the activation of SRB is the strongest at 37℃, the existence of SRB increases the corrosion to carbon steel,and ,the effection of SRB corrosion by Fe2+ is related with the temperature: at 37℃, Fe2+ increase the SRB corrosion，but it reverses at 60℃.These results agree with the phenomenon of inner corrosion of sheath—tube of Wen 10-1 in the Zhongyuan oil field. |
