Abstract: In order to master the corrosion status of aged oilfield pipeline and scientifically assess the pipeline operationconditions in time, a corrosion prediction model for buried steel pipeline has been built. Based on the local corrosion testingdata in oilfield gathering pipeline, the remaining service life for oilfield gathering pipeline is predicted by extreme valuedistribution method. The maximum corrosion pit depth is given by extreme distribution probability statistics, the pipelineremaining service life is also estimated by local corrosion development empirical formula. The predictive results show thatthe remaining service life of pipeline from Shuwulian to Initial Station is 6.2 years, that of pipeline from Shusilian to InitialStation is 11.2 years, and that of thin oil pipeline from Shuyilian to Shuwulian is 4.1 years. Entering the late stage of servicelife, the pipelines should be maintained and repaired with proper measures, and the time interval for pipeline reevaluationshould be half of the predictive remaining service life this time.
