在油田开发过程中 ,随着原油含水的上升 ,地面输水输油管线及井下油管和注水管线腐蚀越来越严重 ,其中 ,细菌引起的腐蚀已成为主要因素之一 ,不仅损害管线设备 ,而且腐蚀产物及代谢产物还会对地层造成伤害。从吉林油田新立采油厂地下水取样可知 ,硫酸盐还原菌 (SRB)高达 1× 1
In the process of oil field development, with the increase of crude oil water content, the corrosion of ground water transport pipeline and downhole tubing and water injection pipeline is more and more serious. Among them, bacteria-induced corrosion has become one of the main factors, not only damaging pipeline equipment, but also corrosion Products and metabolites can also cause damage to the formation. From the groundwater sampling in the Xinli Oil Production Plant in Jilin Oilfield, it can be seen that the sulfate-reducing bacteria (SRB) up to 1 × 1
