基于可视化技术的3D井地磁测人机交互反演

3D MAN-MACHINE INTERACTIVE INVERSION OF SURFACE AND BOREHOLE MAGNETIC DATA BASED ON VISUALIZATION TECHNOLOGY

可视化技术可以直观、方便地描述诸多地质现象,被广泛地应用于地球物理工作中。井中磁测和地面磁测资料的单一资料反演具有一定的局限性,容易产生多解性。笔者阐述了基于可视化技术的3D井地磁测人机交互反演的方法原理和关键技术,并应用于大冶铁矿实际资料的反演解释。实践证实,该方法不但可以利用地面和井中两种资料的优势,还可以充分发挥解释人员的经验,克服了单一资料反演的缺陷,在找矿过程中获得了良好的效果。

Because of its intuition and convenience,visualization technology is generally applied in geophysics.However,there exist certain limitations in inversing surface or borehole magnetic data alone,which may easily cause multiplicity.In this paper,the authors demonstrated the principle and crucial technology of 3D man-machine interactive inversion of surface and borehole magnetic data,and applied it to the Daye iron mine.This method not only has the full advantage of the surface and borehole magnetic data but also possesses the experience gained by interpretation workers.At the same time,it overcomes the disadvantages of inversing either of them alone and can get favorable result in mineral exploration.
