METHOD OF RECORDING DATA OF RADIOACTIVE-TRACER LOG AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC G01V5/12 

FIELD: mining.

SUBSTANCE: irradiation of the medium under study in the well with the radiation source is carried out, the recording of intensity of gamma radiation, amplification and digitization of the recorded signals, their transfer to the surface and automatic stabilization of the energy scale, including the restoration of zero level of the amplified output signal, while performing the periodic accumulation of the recorded signals in the form of the amplitude spectra, and the restoration of the zero level of the amplified output signal is carried out in a cyclic mode, at the beginning of each period of accumulation of the amplitude spectra.

EFFECT: improving accuracy of detecting of gamma-ray energy.
