摘要
文中主要介绍了长输油气埋地管道检测中的外检测技术及应用,其中定期地面检测包括电压梯度、电磁衰减、磁共振成像、地面穿透雷达、综合外检测技术等,永久监测技术包括腐蚀监测、泄漏监测、光纤监测等技术。文中通过对各种技术的介绍,现场的应用实例,突出了各方法的优势与待解决的问题,对外检测技术进行分析并提出研究方向。
This paper mainly introduced the external detection technology and its application in the detection of long-distance oil and gas buried pipeline.The regular ground detection includes voltage gradient,electromagnetic attenuation,magnetic resonance imaging,ground penetrating radar,comprehensive external detection technology,etc.,and the permanent monitoring technology includes corrosion monitoring,leakage monitoring,optical fiber monitoring,etc.In this paper,through the elaboration of various technologies and field application examples,the advantages of each method and the problems to be solved were highlighted,the external detection technology was analyzed,and the research direction was put forward.
