Abstract

The exciting electric absolute phase measurement and time frequency exciting electric multiple parameter simultaneous measurement technology belongs to the field of physical exploring application technology. The present invention is exciting polarization process to measure absolute phase and measures several parameters in time domain and frequency domain simultaneously and includes: recording the potential difference across the measurement electrodes of the power supply square wave in time domain, calculating to find out the real part and virtual part of the fundamental wave, and finding out the absolute phase of exciting polarization. The technological scheme also includes interference suppressing measures and results. The present invention makes it easy to develop exciting polarization instrument with the features of multiple frequency, multiple parameters and low cost, and has unique effect in the theoretic research and application of exciting polarization.

Description

technical field [0001] The invention relates to a method and an instrument for measuring parameters of geological exploration and geophysical prospecting, in particular to a method and an instrument for simultaneously measuring the absolute phase of IP and multiple parameters of IP and time-frequency IP. Background technique [0002] So far, most domestic survey instruments used by domestic geological exploration organizations are time-domain IP instruments. In the frequency domain, there are only instruments that can measure the potential difference of two frequencies and obtain the video dispersion rate through calculation. The three-frequency IP instrument that appeared later measures the relative phase. At present, there is no instrument for measuring absolute phase in China, and there is no instrument for simultaneous measurement of time-frequency IP multi-parameters. Most of the representative instruments in foreign countries are multifunctional electrical instruments...
