摘　　要：含腐蚀缺陷油气管道剩余寿命预测是管道完整性及安全性评价的重要组成部分.以灰色理论的基本模型为基础,提出了管道剩余寿命预测的一种方法,包括预测腐蚀速率的基本步骤以及根据腐蚀速率预测剩余寿命的基本方法,为油气管道腐蚀检测周期的确定提供了一种依据.Remaining life prediction of oil and gas pipelines with corrosion defects is an important part of pipeline integrity and safety evaluation.Based on the basic model of the grey theory,a method for predicting remaining life of pipelines was proposed.This method included the steps of the corrosion rate prediction and the basic idea of remaining life prediction based on corrosion rate and could provide a basis for inspection cycle of oil and gas pipelines.
