摘要

本文根据逆磁致伸缩效应及电磁感应原理，针对石油套管的结构，研制了四个感应探头的电测仪器，首次利用该仪器对石油套管在三点弯载荷作用下进行了电磁检测试验，电磁信号与应力的变化呈现很高的一致性。结果表明：基于电磁感应原理检测石油套管应力的方法是有效可行的。

Abstract

Based on the principle of reverse magnetostriction effect and electromagnetic induction, four sensors were developed to examine the structure of an oil casing. An electromagnetic test was carried out for the oil casing under three-point bending load by this instrument. The changes of the electromagnetic signals and the stresses are very highly consistent. The results show that the method of detecting the stresses of oil casing pipes based on the electromagnetic induction principle is effective and feasible.
