Abstract

With the development of formation element logging

it is one of the key points for technicians to improve the resolution of detectors in the probe. In recent years

the LaBr

:Ce scintillation detector has been gradually implemented in the field of neutron logging with excellent response performance. Based on the Monte Carlo method

the sedimentary energy spectra of LaBr

:Ce and NaI detectors are compared and analyzed. The formation logging model is established. The energy spectra of hydrogen H and Fe are observed by D-T pulse neutron source and two kinds of detectors. The simulation results show that the LaBr

:Ce detector has higher calculation accuracy than the NaI detector when the interference of various formation elements is overlapped when measuring common formation elements. The LaBr

:Ce high resolution crystal is in the complex formation. The detection efficiency in elemental logging is higher.
