摘　　要：阐述了目前国外先进的超声智能爬机检测管道腐蚀状况的基本原理 ,根据我国使用引进的超声爬机检测中存在的问题 ,结合我国石油油质的实际情况 ,分别做了原理性试验和杂质、气泡、噪声等外部干扰试验 ,通过试验现象的分析 ,指出研制爬机时 ,其探头阵结构需要兼顾检测精度和探头间存在的声波干扰这两方面的因素 ,数据处理部分则需要剔除由杂质、气泡或者抖动引进的虚假数据。This article introduces the principle of the advanced ultrasonic intelligent creeper inspection for the pipeline corrosion abroad. On the basis of the problems existed in the ultrasonic creeper inspection, combining the actual condition of China oiliness , the principle test and the impurity, gas pocket, noise ,ect. of the external interference test were conducted. Through analysis of the test, the author points out that the probe array structure should give attention to both the inspection and the sound wave interference between the probes, and the data processing unit shall eliminate the illusive data caused by the impurity, gas pocket or dithering.Subject terms:pipeline co
