Spectrometric gamma-ray: solved tasks and development prospects

The geological capabilities of the spectrometric gamma ray logging (SGL) method are considered. The advantage of SGC over its integral modification (GK-I) is substantiated. It is proposed to replace GK-I in the standard complex of well geophysical surveys (GIS) with SGC, to increase the reliability of constructing a geological and mineralogical model of formations. Based on the analysis of measured and influencing quantities, a method has been proposed to increase the reliability of measurements using SGC equipment, based on the use of the methodology of calibration-correction functions (CPF).
