摘　　要：试验发现金属探测技术、磁应力检测技术、瞬变电磁检测技术等3种检测技术,对废弃井检测有较好的信号响应,探地雷达检测技术、PCM管道探测技术可以辅助排除金属管道等干扰信号。采用组合探测方案,应用标准化的探测流程成功定位了1201口废弃井,对其中的341口废弃井进行了开挖验证,312处井口定位准确,准确率达91.5%。Detection techniques including metal detec- tion technology, magnetic stress detection technology and transient electromagnetic detection technology were found to respond well in the detection of aban-doned wells. Ground penetration radar and PCM piping detection technology facilitated the filtration of signal interference from metal piping. Using the com- bined detection scheme, 1201 abandoned wells were successfully located by the standardized detection process, and 341 of them were excavated for verification, among which 312 wellheads were located accu- rately with accuracy rate of 91.5%.
