超声波在石油钻杆损伤检测中的应用

腐蚀疲劳与应力损伤是石油钻杆损坏的最主要原因,钻杆损伤检测可以有效地预防和减少钻具因失效而引起的质量事故。阐述了石油钻杆健康监测中损伤识别的关键问题,介绍基于超声波的损伤定位定量方法。根据其基本结构和受力特点,以石油钻井中常用5〞钻杆为对象进行损伤研究,用超声波纵波直接接触法检测钻杆,并对探伤结果进行分析和应用。结果表明,超声波可对已定位损伤的石油钻杆的损伤进行定量分析,通过实例验证了其对结构损伤诊断的有效性。

The Application of Ultrasound in the Detection of Oil Drilling Pipe Damage

Corrosion fatigue and stress injuries are the main reason for damage to the oil drilling pipe,while the flaw detection technology is the effective way to prevent and reduce the quality accident from damaged drilling pipe.In this paper,health monitoring on oil drilling pipe was key issues identified in the damage diagnosis,and the ultrasound-based damage diagnosis method was introduced for localization and quantification.Taking the5 drilling pipe which is commonly used in oil drilling for injury study,in acc...
