Abstract

In this work, the mitigated sulfate-reducing bacteria (SRB) corrosion of N80 steel in the tight gas produced water containing condensate oil was investigated. Results demonstrated that condensate oil exhibits an inhibition effect on both uniform and localized corrosion. Condensate oil has a toxic impact on SRB, resulting in a significant decrease in cell concentration, as observed in fluorescence images and cell counts. The corrosion rate caused by SRB reaches up to (0.086 ± 0.004) mm/y, and it declines to (0.024 ± 0.007) mm/y in the presence of condensate oil. SRB localized corrosion ((0.75 ± 0.04) mm/y) is also mitigated by condensate oil.

减轻了N80钢在含凝析油致密气采出水中硫酸盐还原菌的腐蚀

研究了N80钢在含凝析油致密气采出水中硫酸盐还原菌（SRB）的缓蚀性腐蚀。结果表明，凝析油对均匀腐蚀和局部腐蚀均有抑制作用。凝析油对SRB具有毒性影响，如荧光图像和细胞计数所示，可导致细胞浓度显著降低。SRB的腐蚀速率可达（0.086 ± 0.004）mm/y，存在凝析油时腐蚀速率降至（0.024 ± 0.007）mm/y。凝析油也减轻了SRB局部腐蚀（(0.75 ± 0.04)mm/y）。

期刊介绍： Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies. This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
