Description

technical field [0001] The invention relates to an electrical prospecting instrument, in particular to a distributed time-domain IP receiving device and a realization method. Background technique [0002] Electrical prospecting is to use the differences in the electromagnetic properties and electrochemical properties of rocks and ores in the earth's crust, and through the observation and research of the spatial distribution and time characteristics of the electromagnetic field, it is possible to find different types of useful minerals, find out geological structures, and solve geological problems. geophysical prospecting methods. [0003] As an important branch method of electrical prospecting, induced polarization (IP) is based on the two physical parameters of resistivity and polarizability, and can provide the distribution information of the conductivity and electrochemical activity of the underground medium. Time-domain induced polarization (TDIP) has relatively simple ...

Problems solved by technology

[0005] ① The number of channels of the receiver is small (single channel or few channels), and the efficiency of field work is low;

[0006] ② The receiver has poor detection signal resolution and low measurement accuracy;

[0007] ③The receiver does not have the function of full waveform recording, and generally only provides an apparent polarizability after multiple superpositions or several moments after power failure, and cannot perform subsequent denoising processing and data quality evaluation;

[0008] ④The receiver has no real-time monitoring data quality function, and can only blindly superimpose collection
