is designed for rock neutron parameters detection, oil/gas saturation estimation after some neutron lifetime (effective capture cross section Σa) and water-saturated porosity coefficient determination (water content).
Application:
Unlike the pulsed neutron gamma-ray logging tool this apparatus is effective in high natural radioactivity rock and borehole radioactive salts.
TzSP-2INNK-43 logging tool is to be run with GECTOR, VULCAN V3 and KEDR log recorder with one-core or three-core cable.
