Investigation of the Influence of the Magnetic Field of a Well on the Neutron Tube of a Geophysical Apparatus

  • 14 Accesses

The results of experimental studies of the effect of the magnetic field of the well casing on the operation of the gas-filled neutron tube used in the logging equipment are reported. The operation of the ion source was evaluated in terms of the parameters of the pulsed currents of charged particles recorded at the target of the neutron tube. Analysis shows that a longitudinal magnetic field, as compared with a transverse magnetic field, has a greater influence on the performance of the tube. Of the screening methods studied the one with a robust magnetic-steel housing for the equipment turned out to be most effective.
