- 摘要:
- 在分析了油田埋地管道常用的不开挖防腐层检测法(包括管中电流—电压法、交流电流衰减法、人体电容法、变频—选频法、直流电压梯度法、密间隔电位法等)特点的基础上,提出了分别适用于长、中、短距离输油管道的不开挖防腐层检测方法。
There are several methods to detect buried pipeline anticorrosive layer without excavation, in-eluding pipe current-voltage method, AC attenuation method, Pearson method, frequency conversion and se-lection method, DC voltage gradient method, close interval potential survey method, etc. Based on the analysisof above-mentioned methods, this paper indicates the corresponding methods respectively suitable for long,medium and short distance pipelines.2010,2(2): 112-113 收稿日期：2009-10-26分类号：TE988.2作者简介：衣红兵(1960-),辽宁人，高级工程师，1985年毕业于辽河油田职工大学，现从事油气管道和油田地面工程建设工作.
