摘　　要：基于灰色关联分析方法,根据集输管道在线腐蚀监测数据,采用剪切应力表征湍流两相流动对管道内壁的冲刷作用,以湍流强度表征湍流传质强化对腐蚀的影响程度,同时集成普光气田集输管道室内静态腐蚀实验数据,建立了普光气田集输管道动态腐蚀预测模型,为普光气田集输系统腐蚀监测及安全管理提供了依据。In this study, the shear force is applied to characterize the effects of two-phase turbulent flow on internal wall, the turbulence intensity was applied to characterize the effects of turbulent mass transfer enhancement on corrosion and also the indoor static corrosion experiment data is integrated, so that the corrosion prediction model of Puguang gas gathering pipelines is established based on grey relational analysis method and according to online corrosion monitoring data, which can provide the basis for corrosion monitoring and safety management of the transmission system.
