Abstract Corrosion of X80 pipeline steel under sulfate-reducing bacterium (SRB) biofilms, which formed in a culture medium at different times, in a simulated CO 2 -saturated oilfield produced water was investigated. Both planktonic and sessile SRB cells survived after 21 days of immersion in the water under carbon source starvation. The biofilms pre-cultured with a longer time increased the corrosion rate of the steel. At 37 °C, it took about 4 days for SRB to grow and then participate in the steel corrosion. The SRB also facilitated localized corrosion. The SRB biofilm, once deactivated, would no longer affect the steel corrosion.

碳源饥饿模拟CO 2 饱和油田采出水中硫酸盐还原菌生物膜对X80管线钢的腐蚀研究

摘要 研究了模拟CO 2 饱和油田采出水中不同时间在培养基中形成的硫酸盐还原菌（SRB）生物膜对X80管线钢的腐蚀。在碳源饥饿下浸入水中 21 天后，浮游和固着 SRB 细胞都存活下来。较长时间预培养的生物膜增加了钢的腐蚀速率。在 37 °C 时，SRB 大约需要 4 天才能生长，然后才参与钢腐蚀。SRB 还促进了局部腐蚀。SRB 生物膜一旦失活，将不再影响钢腐蚀。
