Year: 2025
Type: article
Abstract: ABSTRACT This study focuses on the corrosion rate prediction of gas field wellbores. Considering the synergistic effect of corrosion factors such as multiphase flow, temperature, pressure, fluid velocity, pH value, microorganisms, and chloride ions, a CPD‐well multiphase flow corrosion prediction model, which is based on Norsok M506 model, is constructed by utilizing the corresponding parameters of shut‐in wells and production wells. The verification of the predicted corrosion rate is carried out based on MIT logging data of the gas wells. The results show that the determination coefficient R2 is between 84.6% and 92.1%. To validate the improved quality, a comparison is performed among the CPD‐well, Norsok M506, and De Waard 95 model. Detailed discussions are provided in this study.
