摘　　要：针对油气管道埋深检测展开研究,首先理论分析金属管道施加高频电流源后在空间的磁感应强度分布规律,借助磁场计算器进行二维数值计算,结果表明理论值和计算值误差小于5%;然后优化数值模型计算结果,可以看出,埋地管道近表面磁感应强度在出现最大值后随着距离管道中心越远而逐渐减小,采用函数y_(1)=y_(0)+A·e^(R0a)对磁感应强度进行拟合可以动态了解管道埋深情况;最后对管道试件进行了试验分析,结果表明理论值和试验值误差小于5%,并分析得到激励电流和频率对磁场信号的影响规律,可为后期提高检测精度和工作效率提供数据支撑。The research is carried out for the detection of buried depth of oil and gas pipelines.Firstly,the distribution law of magnetic induction intensity in the space of metal pipelines after applying high-frequency current source is theoretically analyzed.The two-dimensional numerical calculation with the help of magnetic field calculator shows that the error between the theoretical value and the calculated value is less than 5%;Then the calculation results of the optimized numerical model can be seen that the magnetic induction intensity at the near surface of the buried pipeline decreases gradually with the distance from the center of the pipeline after the maximum value,and the function y_(1)=y_(0)+A·e^(R0a) can dynamically understand the buried depth of the pipeline by fitting the magnetic induction intensity;Finally,the results of the test bench show that the error between the theoretical value and the test value is not more than 5%.The influence of the excitation current and frequency on the magnetic field signal is analyzed to provide data support for improving the detection accuracy and work efficiency in the later stage.
