大深度激发极化法初步探讨

A PRELIMINARY DISCUSSION ON THE GREAT DEPTH INDUCED POLARIZATION METHOD

为了寻找埋藏较深的金属矿体，需要研究大深度激发极化法。本文围绕提高信噪比的关键问题：时间或频率制式的选择、双频大功率激电系统、大深度激电排列技术、消除电磁感应耦合效应等进行了探讨，这有益于开展大深度激发极化法的研究工作。

In order to seek for metallic orebodies buried at relatively great depth, we should study the great depth induced polarization method. The present paper has made a preliminary discussion on some key problems around the elevation of signal-to-noise ratio, such as the selection of time domain frepuency system, the dual-frequency high power IP system, the great depth IP array technique, and the elimination of coupling effect of electromagnetic induction. This discussion contributes to the research on the great depth induced polarization method.
