DEVICE FOR GEOELECTRIC PROSPECTING Russian patent published in 1994 - IPC

FIELD: electric methods of prospecting. SUBSTANCE: device has the first registrar, generator frame and generator, connected with synchronization unit and with power amplification and current measurement unit. Receiving frame is connected in series with the first selective amplifier, the first compensator, the first amplifier, the first detector. Receiving dipole, connected in series with the second selective amplifier, the second compensator, the third amplifier, the third detector, identification system are brought into the device additionally. Group inputs of identification system are connected simultaneously with the second registrar and with computational unit, output of the system is connected with the first registrar and the fourth amplifier, which is connected with feeding dipole and the second selective amplifier. Output of computational unit is connected to the second registrar. Inputs of computational unit is connected with the first, the third and the second detectors. The second detector has output connected with power amplification and current measurement unit. The latter is connected to feeding dipole and to generator frame. Output of the second amplifier is connected with synchronization unit. Inputs of the second amplifier are connected with receiving dipole and receiving frame correspondingly. Output of the second compensator is connected with selective amplifier, input of the second compensator is connected with the third amplifier. EFFECT: improved precision of prospecting; improved precision of determination of depth of occurrence. 2 cl, 10 dwg
