摘要
针对近年来输油管道盗油案件频发,管道盗油孔在实际管道巡护中常态化检测难以实施的问题,介绍了三轴复合专项内检测的检测原理、组成结构和检测实施流程。通过现场工程应用,利用三轴空间磁场信号和涡流信号相结合的方法进行判读,识别盗油孔特征信号,结果表明三轴空间磁场信号对管道外壁信息比较敏感,而涡流信号受趋肤效应影响,主要对管道内壁信息比较敏感。利用盗油孔特征信号一致性原则,并结合检测信号的特征和盗油孔的打孔方式,有效识别出了管道盗油孔的信号,避免了管道盗油孔信号的误判和漏检,为今后输油管道盗油孔常态化检测流程、数据分析和信号识别提供了技术支持。
In response to the frequent occurrence of oil pipeline theft cases in recent years and the difficulty in implementing routine detection of theft orifices during actual pipeline maintenance,this paper introduced the detection principles,system architecture,and implementation procedures of triaxial composite specialized in-line inspection.Through field engineering applications,the study combined triaxial spatial magnetic field signals with eddy current signals to interpret and identify characteristic signals of theft orifices.Results demonstrated that triaxial spatial magnetic field signals exhibited high sensitivity to external wall information of pipelines,while eddy current signals primarily responded to internal wall characteristics due to skin effect influences.By applying the principle of characteristic signal consistency for theft orifices,combined with signal features and theft methodologies,the system effectively identified pipeline theft orifice signals,avoiding misjudgment and missed detection.This research provided technical support for establishing standardized detection procedures,data analysis,and signal recognition protocols for routine oil pipeline theft orifice inspection in the future.
