摘　　要：输油管道腐蚀机理复杂,难以采用常规数学方法进行描述。以灰色系统理论为基础,探讨了应用EDGM模型预测输油管道腐蚀速率的方法,并对海底管道和油田管道的腐蚀速率进行了仿真预测。结果表明:腐蚀速率预测值与实际值较为吻合,预测方法具有较高的精度。利用该方法,可以在测量数据较少的情况下预测输油管道的腐蚀速率,为输油管道的腐蚀防护和安全管理提供依据。The corrosion mechanism of oil pipeline is complex,and it is difficult to use traditional mathematics method to describe it.Based on the grey system theory and EDGM model,a corrosion rate prediction method is studied. The simulated prediction experiments are carried out on submarine pipeline and oilfield pipeline. The result shows that predicted results agree well with the true results and have high accuracy. This method can predict the oil pipeline＇s corrosion rate by using less measured data,and it provides a basis for the corrosion protection and safety management of oil pipeline.
