摘　　要：根据气田集输管道腐蚀诸多因素的复杂性和不确定性以及管道腐蚀剩余寿命预测的困难性,比较分析了适用于集输管道腐蚀预测的两种方法。研究表明,这两种方法能较好地预测集输管线腐蚀变化趋势,为管道剩余寿命预测提供可靠依据。Based on the complexity and uncertainty of corrosion in gas-gathering and gas-transmission pipeline and the forecasting difficulty of pipeline's residual life,two methods for predicting pipeline corrosion have been contrasted and analyzed.The research indicates that the variation trend of pipeline corrosion can be predicted very well by the two methods which provide a reliable basis for predicting the pipeline's residual life.
