摘要
对磨溪气田 M60、M70两油井污水中硫酸盐还原菌 (SRB)的研究 ,发现在磨溪气田存在高温细菌腐蚀。实验结果表明 ,液体中的 M60、M70 SRB均只能在 60°C以下的温度中存活生长 ,而附着在试片上的 M60和M70 SRB则可以在 70°C以下的温度下生存 ,说明粘附于试片上的 SRB具有更强的耐高温性能。M70 SRB生物活性和耐高温性比 M60的 SRB高 ,且 M70的 SRB对 N80钢的腐蚀影响也大于 M60。
Sulfate reducing bacteria (SRB) isolated from waste water of M60 and M70 gas wells have been used to assay the high temperature microbiologically induced corrosion (MIC) The results showed that in water below 60°C, the SRB from M60 and M70 could survive, on the surface of coupons in biofilm both could exist at 70 °C The temperature resistance and activity of SRB from M70 well was higher than that of SRB from M60 well The effect of SRB from M70 on corrosion of N80 steel was more serious than SRB from M60
