    摘要:

    针对高含水原油集输管道内腐蚀穿孔事故日趋严重的工程实际问题,对高含水原油集输管道内腐蚀高风险点预测及内腐蚀缺陷监测方法进行了综合研究。基于原油集输管道管内介质的液滴携带机理,给出了该类管道内腐蚀高风险点的预测和判定方法;基于场指纹腐蚀监测原理,研究了代表腐蚀缺陷深度的指纹系数的空间分布规律,给出了其与管道壁厚减薄量的对应关系曲线,建立了高含水原油集输管道内腐蚀状况的评估模型。研究可为高含水原油集输管道科学管理及保障原油集输管道安全运营提供技术支撑。

    Abstract:

    In view of the increasingly serious engineering problems of internal corrosion perforation accidents in high-water-cut crude oil gathering and transportation pipelines, a comprehensive study was carried out on the prediction and monitoring methods of high-risk points of internal corrosion in this type of pipelines. Based on the droplet carrying mechanism of the fluid medium, a method for predicting and judging high-risk points of internal corrosion in this type of pipeline is given; Based on the principle of field signature method corrosion monitoring, The spatial distribution law of the fingerprint coefficient representing the depth of corrosion defects is studied, The corresponding relationship curve with the thickness reduction of the pipeline is given, and the evaluation model of the internal corrosion condition in the high-water-cut crude oil gathering and transportation pipeline is established.It can provide technical support for the scientific management of crude oil gathering and transportation pipelines with high water content and to ensure the safe operation of crude oil gathering and transportation pipelines.
