国外油气管道内检测技术的前沿应用

Cutting-edge Applications of Foreign In-line Inspection Technologies to Oil and Gas Pipeline

随着计算机、自动化以及数字处理技术的快速发展,国内外各种新型管道内检测器技术和设备不断得到应用和普及。通过分析外检测技术的不足,介绍了国外较成熟、先进的管道内检测(智能检测)技术,包括阴极保护电流测绘内检测技术、多重数据采集装置集合技术、电磁声波传感内检测技术(EMAT)、旋转漏磁内检测技术以及"高通过性"管道内检测技术等。通过借鉴国外研究内检测器所取得的成功经验,对国内的内检测器研究和工程应用起到一定的借鉴作用。

With the rapid development of the compute,automation and digital processing technologies,various new pipeline in-line inspection technologies and equipment are popularly applied at home and abroad.By analyzing the shortcomings of widely used in-line inspection technologies at home,technologies of advanced,mature pipeline in-line inspection are introduced,including cathodic protection current mapping in-line inspection technology,multiple data set technology,electromagnetic acoustic testing,spiral magnetic flux leakage technology and＂high passage＂pipeline inspection technology,etc.By referring to the successful experience acquired by foreign researchers,this paper is expected to be used as a guidance to in-line inspection tools research and engineering applications.
