FIELD: physics; geophysics.
SUBSTANCE: invention relates to geophysics logging meant for studying the structure of the Earth, mainly when studying exploratory, service and field wells, and specifically methods of analysing characteristics of geological strata around a well. The method of gamma-ray logging a well involves generation of gamma-ray quanta and their pick up using a detector, where the detector used is a high-voltage xenon detector in various versions of its implementation.
EFFECT: obtaining data with higher energy resolution, spatial resolution, as well as in high temperature wells.
