AbstractPipeline corrosion induced by sulfate-reducing bacteria (SRB) is particularly severe during the hydraulic fracturing technology in shale gas exploitation. To investigate evolution of beneath SRB biofilms, 49-day experiments were performed with and without SRB. The weight loss experiment demonstrated that Blank group was mitigated product film. In contrast, exhibited an initial inhibitory phase followed exacerbation. Scanning electron microscopy (SEM) revealed stratification group, whereas initially formed colonies extracellular polymeric substances (EPS), eventually biofilm evolved into a mixed layer product. 3D showed relatively flat surface group. Conversely, pits circular could reach depth 29.77 μm, significantly greater than Over time, SRB-induced deepened from edges to center widened approximately 740 accompanied increase quantity. Energy Dispersive Spectrometer (EDS) X-ray photoelectron spectroscopy (XPS) analyses detected presence elements P, S, FeS serving as important indicators corrosion. Electrochemical higher currents consisted three phases: initial, intermediate, starvation phases. During phase, localized proved be most severe, rate 1.28 mm/a. Therefore, study should prioritized localization phenomena.Keywords: Shale pipelinesulfate reducing bacteriapitting evolutionlocalized corrosionelectrochemical Disclosure statementThe authors declare they have no known competing financial interests or personal relationships appeared influence work reported this paper.Additional informationFundingThis funded National Natural Science Foundation China (Grant No. 52174062).
