Abstract:

利用扫描电镜(SEM)、能谱、X射线衍射仪(XRD)和超景深三维立体显微镜等表面分析手段,调查研究油田污水集输管线材料的腐蚀和结垢行为。实验结果表明,暴露在没有添加杀菌剂的污水中30d的试样表面形成了大量的垢状沉淀物,局部放大可以发现以胞外聚合物为主的生物膜覆盖在试样表面,此时生物膜的厚度高达169.6μm,生物膜中含碳酸盐垢和细菌代谢产物硫铁化合物,且膜下基体材料局部腐蚀孔深度达到23.96μm。在连续添加100mg/L有机胍类杀菌剂1个月后,试样表面覆盖物中以无机矿物为主,且膜层厚度较未添加的薄,厚度为48.6μm,膜下腐蚀较均匀,局部腐蚀轻微。硫酸盐还原菌参与的生物作用是管线局部腐蚀穿孔的主要原因之一。
