摘要
研究了一种基于多分量瞬变电磁法的套损检测系统,由探测单元、发射单元、接收单元、采集传输单元和地面单元组成。本系统在1个垂直探头和8个水平探头中分别发射双极性方波作为瞬变电磁激励信号,在发射信号的间歇接收套管上产生的感应信号,根据探头接收到感应信号的异常变化,来识别套损类型,判断套损位置。
A Case-damage Detection System based on Multi-component Transient electromagnetic method is established, which consists of detection unit, transmission unit, reception unit, collection transmission unit and ground unit. This system includes a vertical probe and eight horizontal probes, the probes are used to transmit bipolar square wave signals, and receive induction signals produced on the case at intermittence times. Case damage types and locations can he identified by detecting abnormal changes of the induction signals.
