摘要
由于不合格水质的长期注入,在近井地带、尤其是环套空间造成水质严重恶化,引起SRB菌、铁细菌及腐生菌大量繁殖,是造成套管严重腐蚀的主要原因之一。通过加入一种具有缓蚀、杀菌和防垢综合性能的化学保护液,可抑制SRB细菌的生长,减轻环空水的腐蚀性,从而达到保护油套管的目的。
One of the culprits of corrosion of oil weU annular pipe is the large reproduction of SRB, iron bacteria and saprogenic bacteria due to water quality deterioration in annular pipe because of long-term off-spee water injection. The injection of chemical protection liquid with corrosion inhibition, bacteria killing and anti-fouling performance can effectively control the growth of SRB, mitigate the corrosivity of water in the annular pipe and thus protect the annular pipe from corrosion.
