摘要:
随着连续油管的大规模投入使用，油管损伤引起的安全事故与日俱增。为了及时对油管使用过程中产生的缺陷进行检测、识别及定位，基于磁记忆检测方法，对连续油管进行管壁刻伤试验，结合workbench有限元方法模拟刻伤处的应力分布，对比分析不同刻伤类型产生的典型信号特征及信号特征值变化趋势。结果表明：刻伤部位的磁记忆信号曲线与应力分布曲线的特征及峰值变化趋势一致，随着刻伤宽度的增加，磁记忆信号曲线及应力分布曲线由单峰向双峰过渡，磁记忆信号峰值及应力峰值呈降低趋势；随着刻伤深度的增加，磁记忆信号曲线及应力分布曲线峰峰值增加，磁记忆信号峰值及应力峰值呈升高趋势。
Abstract:
With the large-scale use of coiled tubing, the safety accidents caused by tubing damage are increasing day by day. In order to detect, identify and locate the defects generated in the using process of tubing in time, the tubing wall cutting experiments of coiled tubing were conducted based on the magnetic memory testing method. The stress distribution in the cutting position was simulated by combining with the workbench finite element method, and the typical signal characteristics and the change trend of signal characteristic values under different cutting types were compared and analyzed. The results showed that the characteristics and peak value change trend of the magnetic memory signal curve in the cutting position were consistent with those of the stress distribution curve. With the increase of cutting width, both the magnetic memory signal curve and the stress distribution curve transited from single peak to double peaks, and the peak values of magnetic memory signal and stress decreased. With the increase of cutting depth, the peak-peak values of magnetic memory signal curve and stress distribution curve increased, and the peak values of magnetic memory signal and stress increased.
