| الوصف: | To make an effective correlation analysis on the factors influencing the corrosion and perforation of high sulfur associated gas pipeline in Tahe Oilfield, the pipeline flow parameters were calculated using multiphase flow transient model, and a method combining Pearson correlation coefficient with Apriori association rule mining algorithm was proposed to determine the associativity rules that affecting corrosion perforation. Results showed that the multiphase flow transient model revealed the variation laws of pipeline temperature, pressure, flow rate, and liquid holdup along the pipeline. Meanwhile, the degrees of influences of medium parameters and flow parameters on corrosion were as follow: liquid holdup (0.732) > temperature (0.696) > pressure (0.677) =CO2 partial pressure (0.677) = H2S partial pressure (0.677) > gas flow rate (0.618) = gas wall shear force (0.618) > pipe inclination (0.577). The strong correlation rules between the corrosion rate and H2S partial pressure, temperature, liquid holdup, flow rate and pipeline inclination were determined. Besides, the correctness of the association rules was further verified by the high temperature and high pressure dynamic reactor experiment. |
