摘要
分析了频率域激发极化法偶极-偶极装置在金属矿勘查中的技术优势。双频道激电法轻便,抗干扰能力强的特点与多极距偶极-偶极装置水平和纵向分辨力高的技术特点相结合,可提高复杂地形条件下金属矿勘查效果。正演计算了双频激电仪四个频组不同收发距对高极化薄层的分辨能力,总结了双频激电偶极装置野外工作的技术要点。运用二维视电阻率/视幅频率反演软件可提高勘查资料的解释水平。应用实例表明,频率域偶极-偶极方法地质勘查效果明显。
The technological superiority of applying dipole-dipole array dual-frequency induced polarization method on metals exploration is analyzed. The dual-frequency IP instrument is lightweight, and has higher anti-jamming ability, multi-spaced dipoledipole array has better resolution both in horizon and vertical, combined this two advantages will result in a good effect on mental survey even in harsh conditions. The resolution ability with four dual-frequency of the dual-frequency IP instrument is forward computed by modeling and the key point of applying dipoledipole array dual-frequency induced polarization method in field is mentioned. Using the software of apparent resistively/apparent percent frequency effect（PFE） inversion will enhance the ability of data interpretation. The case shows forth that this FD low frequency dipole-dipole combined method has advance effect on metals exploration.
