摘要
To test the performance of the Chinese whole-surface electromagnetic prospecting （SEP） system, system integrations, instrument performances, and large-scale production viabilities in Liaoning province and Inner Mongolia were measured via extensive field tests. Resultant electric fields, magnetic fields, apparent resistivities, impedance phases, and inversion profiles compared favorably with results of commercial equipment from other countries. The inversion results agreed well with the geologic information from boreholes. Field tests showed that the SEP system is stable, reliable, lightweight, and easy to operate, making it suitable and ready for real-field exploration.
为了检验自主研发的地面电磁探测(SEP)系统的性能,在辽宁兴城及内蒙阿拉善等地开展了野外系统集成、仪器性能比对及大规模生产性探测试验。通过与世界先进仪器的发射波形、接收电场、磁场、视电阻率、阻抗相位及反演结果的全方位多角度对比,表明自主研发的SEP系统数据与进口高端仪器的数据基本一致。大规模野外探测试验结果表明,SEP系统性能是稳定的,同时具有轻便、灵敏度高及易操作等优点,便于实际野外勘探生产。
