摘要
在油田站场管道中,腐蚀穿孔时常发生,威胁油气田安全生产.因此,电阻探针通常被应用于不同介质下的管道腐蚀监测.为了提高腐蚀监测的有效性,基于流体力学计算(CFD)有限元模拟,研究了不同介质环境下电阻探针的局部流场分布规律.结果发现,介质为水的探针扰流和剪切力都达到最大,且探针最大剪切力始终出现在套筒孔的两侧.
Abstract
In oilfield station pipelines,corrosion perforation occurs from time to time,threatening the safe production of oil and gas fields.Therefore,resistance probes are usually applied to corrosion monitoring of pipelines under different media.In order to improve the effectiveness of corrosion monitoring,this paper investigates the local flow field distribution law of resistive probes under different media environments based on CFD finite element simulation.It is found that the perturbation flow and shear force of the probe with the medium of water reach the maximum,and the maximum shear force of the probe always appears on both sides of the sleeve hole.
