摘要
抽油杆在采油过程中发生断裂会造成很大的经济损失。发生断裂的主要原因是抽油杆表面的裂纹源在周期性载荷作用下由表及里地扩展。介绍1种自主设计的外穿过式涡流探头,此类探头可以准确、迅速地检测出导致抽油杆断裂的裂纹源,适合抽油杆的在线检测。
The sucker rod is the main loaded component of the oil extraction system in the oil field.If it was broken in the process of production,great losses would be incurred in the suspended operation.The main reason for the break is the crack source in the surface of the sucker rod will spread from surface to interior under the periodic load.This article introduces a kind of self-designed exteriorly-thru-type eddy current probe which can detect the crack source that can lead to the break of the sucker rod,precisely and rapidly,and so,it is suitable for the on-line detection.
