Abstract

Summary

The effect of the inelastic scattering cannot be ignored in the pulsed neutron porosity logging. The impacts of lithology and bulk density on the porosity measurement are remarkably increased compared with neutron porosity logging based on chemical source. The connection of the slowing-down length of neutron with bulk density and hydrogen index was deduced and simulated to correction the influence of bulk density in pulsed neutron porosity logging. As the results suggest, the application of bulk density correction in the pulsed neutron porosity logging will increase the sensitivity to formation porosity and decrease the impact of lithology and shale effect.
