Abstract—Internal corrosion caused by Sulfate-Reducing Bacteria (SRB) poses a critical challenge to shale gas gathering pipelines. This study combines experimental analysis and a Bayesian network-based corrosion probability model to explore SRB corrosion mechanisms and predict corrosion rates. Experimental results demonstrate a direct correlation between SRB concentration and accelerated corrosion rates. The proposed Bayesian model integrates factors such as SRB concentration, temperature, flow rate, and pH, validated against field data with relative errors <35%. This research provides theoretical support for pipeline maintenance strategies.
