高含硫长距离集输管道腐蚀监测技术研究
|
摘要
高含硫气田在开发过程中,管道腐蚀是一个非常突出的问题,特别是长距离湿气集输管道,不同管段腐蚀程度差异很大,仅仅在管道的始末段设置腐蚀监测点很难全面有效地获得管道腐蚀的真实情况。通过对天高线B段管道流体特性模拟分析,研究影响管道腐蚀的主要因素,确定管道严重腐蚀的部位,为长距离集输管道腐蚀监测方法和位置的设置提供依据。通过与目前油气田使用比较成熟的非插入式在线腐蚀监测技术进行对比,本试验在腐蚀监测系统中增设了超声导波监测技术。1年的腐蚀监测试验结果表明,完善后的在线腐蚀监测系统使腐蚀监测信息更加全面有效。
The pipeline corrosion is a very prominent problem in the development process of high sulfur gas field.Especially for the long distance wet gas pipeline,the corrosion degree of different pipe sections has very big discrepancy.It is very difficult to obtain the true situation of pipeline corrosion comprehensively and effectively only by setting the corrosion monitoring points at the beginning and the end of the pipeline.In this paper,the main factors affecting the pipeline corrosion are studied through the simulation analysis of the fluid characteristics of Tiangao B section pipeline,and the sites of serious corrosion of the pipeline are determined,which provide the basis for selecting the corrosion monitoring method and setting the location.Through the comparison of non-inserted on-line corrosion monitoring technologies used in oil and gas fields,ultrasonic guided wave monitoring technology is added in the corrosion monitoring system in this experiment.After a year of corrosion monitoring test,the results show that the improved on-line corrosion monitoring system makes corrosion monitoring information more comprehensive and effective.
