大地电磁测深远参考技术及应用效果

Remote reference technique in magnetotelluric sounding and its application.

由于大地电磁测深勘探易受人文因素干扰 ,致使资料数据离差大、曲线形态畸变、可信度差。远参考技术是一种有效压制人文干扰的方法。本文阐述了远参考处理方法以及野外采集技术 。

Magnetotelluric(MT) data features large deviation, distorted curve shape and low reliability because MT sounding tends to be affected by cultural disturbances. The remote reference technique is an effective way for suppressing the disturbances and improving data quality. In this paper, issues on data processing and acquisition for the remote reference technique are discussed. The effect of application of the method to MT data is analyzed.
