It is intended for registration of a range of natural gamma radiation, ranges of gamma radiation of radiation capture and density of a stream of thermal neutrons from the closed radio nuclide source of fast neutrons.
Solvable tasks
· assessment of extent of filling with cement of behind-the-casing space;
· allocation of zones of a congestion of gas in intercolumned and behind-the-casing space of wells;
· identification of cavities in a priskvazhinny zone of the terrigenous gas-giving collectors and an assessment of their linear sizes;
· specification of a lithology of the deposits opened with a well.
