摘　　要：介绍一种基于低频涡流检测原理的新型小直径套管 /油管检测仪器。实验和现场试验结果表明 ,该仪器可测量油管套管因腐蚀、磨损、挤压等原因造成的壁厚减薄、变形、破裂等缺损。仪器外径较小 ,可在油管内检测管壁的损坏情况。A new type of slim pipe tool for pipe inspection based on low frequency eddy current measurement principle is introduced in the paper. Laboratory experiment result and field test data prove that the tool is applicable to inspecting casing or tubing flaw, such as eliminated thickness, deformation or broken caused by erasing, fraying and stress. Because of its slim design, this tool can even be applied to detect casing flaw through inner tub.
