TzSP-2INNK-43 Digital dual pulsed neutron-neutron logging tool

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)


Unlike the pulsed neutron gamma-ray logging tool this apparatus is effective in high natural radioactivity rock and borehole radioactive salts.
