在石油工业中，管柱极易因应力腐蚀和疲劳损伤而产生裂纹。现有的漏磁和磁粉探伤方法不足以检测管柱轴向狭窄裂纹。本文提出的一种新型馈通交流电场测量（ACFM）探头的裂纹检测仿真和实验结果表明，该探头可用于准确、快速、非接触的管柱裂纹检测。该馈通式ACFM探头采用等间距传感器阵列结构，可一次扫描整个管柱周长。(C) 2014 Elsevier Ltd.版权所有。
Pipe string is highly susceptible to cracks caused by stress corrosion and fatigue damage in petroleum industry. The performance of existing magnetic flux leakage and magnetic particle inspection is inadequate to detect narrow axial cracks in pipe string. Results obtained from crack inspection simulations and experiments using a novel feed-through alternating current field measurement (ACFM) probe presented in this paper suggest that this probe can be adopted for an accurate, rapid and non-contacting detection of pipe string cracks. A structure of equal-spaced sensor array of this feed-through ACFM probe is applied to scan the full circumference of pipe string simultaneously in a single pass. (C) 2014 Elsevier Ltd.
