Abstract

The invention discloses a method and an instrument for simultaneous measurement of IP absolute phase and time-frequency IP multi-parameters. The measurement method is: using the time domain method to synchronously record the potential formed between the measurement electrodes by the square waves of different frequencies sent by the power supply electrodes The potential difference curve can be displayed in real time, and the real part and imaginary part of the fundamental wave can be obtained by calculation, and then the absolute phase of the excitation polarization can be obtained, and the simultaneous measurement of multiple parameters of time-frequency excitation can be realized at one power supply. The measuring instruments include synchronously controlled transmitters and receivers, which are equipped with PC104 industrial computers, LCD display screens and storage disks. The transmitter and receiver adopt line synchronization or quartz clock crystal synchronization or satellite positioning synchronization. The invention realizes simultaneous measurement of multiple parameters of IP absolute phase and time frequency IP.

Description

Technical field [0001] The invention relates to a method and instrument for measuring geophysical prospecting parameters, in particular to a method and a measuring instrument for simultaneous measurement of IP absolute phase and frequency IP multiple parameters. Background technique [0002] So far, most of the measuring instruments used by domestic geological exploration institutions have used time domain IP instruments. However, the frequency domain can only measure the potential difference of two frequencies separately and obtain the video scatter rate by calculation. Later, the three-frequency IP instrument 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 multiple parameters of time-frequency induced polarization. Most of the representative instruments abroad are multifunctional electrical instruments. In terms of its IP function, the measurement of frequency dom...
