摘要

随着新测量方法的开发和利用以及新的数据处理和资料解释技术的提高 ,使得磁法勘探可用于城市工程与环境中电磁干扰相对较小的区域 ,且高分辨地探测地表及近地表磁异常。实例表明 ,垂直梯度磁异常测量相对于ΔT磁异常测量具有较好的抗干扰能力 ,同时欧拉反褶积和场源参数成像方法增强了异常的区别和分离能力。结合共偏移距道集地震方法可以给出异常体埋深信息。
With the development and adaptation of new survey methods and the improvement of data processing and interpretation, It's possibility that the magnetic method can be used to detect the surface or near-surface magnetic abnormality, in the area where magnetic perturbation is comparably small. The case showed that the vertical gradient magnetic measurement has better resolution than ΔT, at the same time, Euler deconvolution and iSPI TM enforce the separating ability of abnormality. Combined with common offset gather method, the depths of abnormality were obtained.
