摘　　要：在保持微生物原生态环境条件下,采用绝迹稀释法与静态挂片腐蚀试验,配合微生物显微镜及SEM分析方法,对渤海某油田回注水微生物致碳钢点蚀问题进行了研究,重现了碳钢挂片点蚀历程,得出了微生物在碳钢点蚀形成初期起重要作用的结论,从而为后续碳钢点蚀研究工作指明了方向。The microbe-induced pitting of carbon steel caused by injection water in a Bohai oilfield was studied by the vanishing-dilution method and static cou- pon corrosion test under the microbial ecological en- vironment, as well as with the microorganism micro- scope and SEM analysis method, by which the pit- ting process was reproduced and it is concluded that microbe plays an important role on the early pitting formation, thus pointing out the direction for the follow-up studies on pitting of carbon steel.
