管线腐蚀是影响油田安全生产的重大隐患，也是增加原油生产成本的一个重要因素。多年来广大科技人员一直致力于研究对在设管道的无损检测技术，以便对管线进行定期地检测及时发现问题，采取措施，延长其寿命。本文针对小口径管的检测从检测的技术难点、项目、方式方法、系统的构成，现场检测方案等系统地研究了适合小口径管道无损检测的技术路线、方案和具体实施措施。
Pipeline corrosion is a major hazard affecting the safety of oilfield production, but also an important factor in increasing crude oil production costs. Over the years the majority of scientific and technological personnel have been committed to research on the pipeline in the non-destructive testing technology in order to detect the pipeline in a timely manner to detect problems and take measures to extend its life. In this paper, the technical route, scheme and specific measures for non-destructive testing of small-diameter pipe are systematically studied from the technical difficulties, items, methods and methods, system structure and on-site testing scheme of small diameter pipe.
