| 摘 要： | 为保证穿越河流管段的正常运行,需要定期检测管道埋深。针对定向钻穿越大埋深管道检测过程中电磁信号不稳定导致检测结果不准确的问题,通过改变不同埋深穿越管段的电磁信号校准方法,对One-Pass水下管道检测系统进行优化,提高其在定向钻穿越管道检测中的检测精度。结果表明:利用优化后的电磁信号校准数据计算得到的结果与实际情况的符合度更高,说明优化后的One-Pass检测系统能满足水深40 m范围内的定向钻穿越管道敷设状态检测要求。研究成果对定向钻大埋深穿越河流管段敷设状态检测具有指导作用,对保障穿越河流管段的安全运行具有重要意义。

| Abstract: | For the purpose of ensuring the normal operation of river-crossing pipeline,it is necessary to detect the burial depth periodically.In view of the inaccurate result caused by unstable electromagnetic signals during the detection of directional drilling crossing pipeline due to its large covering,the One-Pass underwater pipeline inspection system was optimized by changing the calibration method of electromagnetic signals in the crossing pipelines with different buried depth to improve the detection accuracy of directional drilling crossing pipeline.The consequences show that the higher degree of compliance of the results calculated according to the calibration data of the optimized electromagnetic signal with the actual situations indicates that the optimized One-Pass inspection system can satisfy the detection requirements for laying status of the directional drilling crossing pipeline within a water depth of 40 m.The research results could be used to guide the detection of the laying status of river-crossing pipeline by directional drilling,and they are of important significance to ensure the safety operation of river-crossing pipeline. |
