在采油过程中最广乏使用的抑制微生物腐蚀的方法是采用化学药剂。从油田开采的最初起就必须对注水进行杀菌处理,这时为防止油层被硫酸盐还原菌污染,只使用低浓度的杀菌剂就够了。在油层受硫酸盐还原菌污染的情况下,定期向采油系统的各个点加入大剂量的杀菌剂是有效的,但是当油矿介质中除硫酸盐还原菌外尚含有其他腐蚀剂(硫化氢、硫化 The most widely used method of inhibiting microbial corrosion during oil recovery is through the use of chemicals. Waterflooding must be sterilized from the very beginning of the field. Only low concentrations of fungicide should be used to prevent the reservoir from being contaminated with sulfate-reducing bacteria. Where the reservoir is contaminated with sulphate-reducing bacteria, it is effective to add large doses of bactericides regularly to the various points in the recovery system, but other caustic agents besides hydrogen sulphate-reducing bacteria (hydrogen sulphide, sulphurised
