摘　　要：多频管中电流检测技术是一项埋地管道防护层破损及漏点检测新技术，其操作简便、定位准确，采用该技术对阿尔善油田输油管道的外防护层进行检验，不仅准确测定了破损点，还为制订被检测管线的管理维修计划提供了可靠依据。The technology of multi - frequency current detection in pipe is a new technology which the destroy and the leak of the profective coating of pipe under ground can be found. The basic principles and detective system has been introduced. The outer profective coating of the petroleum pipeline from the first factory of Meng to the first factory of A of the Aershan oil field was detected in this technology. Not only the destory of the profective coating was found, but the destroied coating was repaired in time, and the basis of the repaired plan of tile pipline was provided. This method has several characteristics of easy to operate and accurate pointing and high detected degree of accuracy.
