is designed for natural radioactive element content quantitative measurements: thorium (Th), uranium (U) and potassium (K) in different wells.

 

 

Description

Features and advantages:

  • interval-by-interval full gamma-spectra accumulation and further digitized data telemetering;
  • improved accuracy in Th U K detection;
  • borehole design effect analytical accounting (diameter, casing, cement bond);
  • referenceless energy scale stabilization and calibration, gain control.

TzSP-GK-S-48/60/76 tool is to be run with one-core and triple-core logging cable.

The digital gamma-ray spectral logging tool TzSP-GK-S-43/48/60/90 contains registration and processing electronic module, telemetry system and scintillator detector with photoelectronic multiplier. The tool is equipped with full software for Vulkan, Gektor recorder and interpretation software for logging in open and cased boreholes.
