Description:
It is used in wells during drilling for any type of flushing fluid.
Overview:

Designed for GIS methods:

  • azimuthally oriented lithological-density gamma-gamma-ray logging to determine the density and effective atomic number of rocks.
  • compensated neutron-neutron logging by thermal neutrons for measuring water-saturated porosity of rocks by the method of compensated neutron-neutron logging by thermal neutrons - 2NNct or by epithermal neutrons - 2NNnt.

Tasks to be solved:

  • control of the design of the wellbore during drilling;
  • image density registration in 16 segments
  • reservoir routing through azimuthal measurements;
  • collector allocation;
  • determining the nature of saturation of the collectors;

The device can operate both from its own and from external power sources. To ensure operation in combination with other devices, the device passes through a transit of 7 wires.

The measuring installation of compensated neutron-neutron logging contains a chamber for placing an ampule source of fast neutrons IBN-8-5 with a neutron output of (1.00 ± 0.20) × 10 7 n / s, the measuring installation of lithological-density logging contains a chamber for placing a gamma source radiation Cs-137 type IGI-C-4 activity from 6.65 × 10 9 to 6.65 × 10 10 Bq.

Neutron source recoverable.
