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。
研究瞭一種基于多分量瞬變電磁法的套損檢測繫統,由探測單元、髮射單元、接收單元、採集傳輸單元和地麵單元組成。本繫統在1箇垂直探頭和8箇水平探頭中分彆髮射雙極性方波作為瞬變電磁激勵信號,在髮射信號的間歇接收套管上產生的感應信號,根據探頭接收到感應信號的異常變化,來識彆套損類型,判斷套損位置。

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 be identified by detecting abnormal changes of the induction signals.
