摘　　要：常规探测方法应用于超深金属管道进行探测时,探测信号不佳会导致探测管线的定位精度和可靠性较低。针对常规探测方法的不足,本文研究了一种磁梯度法与电磁感应竖向剖面法相结合的超深金属管线探测新方法,并总结出一套超深金属管线探测流程。通过工程实例,验证了本文提出的新方法应用于超深金属管道探测的有效性和可靠性,具有良好的工程应用价值。The poor detection signal will lead to the low positioning accuracy and reliability of the detection pipeline,when the conventional detection method is applied to the detection of ultra deep metal pipeline.In view of the shortcomings of conventional detection methods,this paper studied a new method of ultra deep metal pipeline detection based on the combination of magnetic gradient method and electromagnetic induction vertical section method,and summarized a set of ultra deep metal pipeline detection process.The effectiveness and reliability of the new method proposed was verified in the detection of ultra deep metal pipelines through engineering examples,the result showed that the new method had good engineering application value.
