Abstract

Abstract: Background: The widely used bismuth germanium oxide (BGO) detector has low energy resolution in neutron well logging, and thus cannot meet the requirements of some practical applications. Purpose: This study aims to obtain high energy resolution spectrum using a LaBr₃:Ce detector in neutron-gamma logging. Methods: Several common geochemical elements such as H, C and Fe were measured using ²⁴¹Am-Be neutron source with LaBr₃:Ce detector in a radioisotope neutron testing well belonging to China Petroleum Group Logging Corporation, and a commonly used BGO detector was employed to provide a comparison with LaBr₃:Ce detector under the same well logging test condition. Results: The energy spectrum of LaBr₃:Ce detector exhibited higher energy resolution than that of BGO detector, and a clear signal of Fe whilst a very weak Fe signal in energy spectrum of LaBr₃:Ce detector. Conclusion: The application of LaBr₃:Ce detector in nuclear logging has a promising prospect.

Key words: ²⁴¹Am-Be neutron source, LaBr₃:Ce detector, Energy resolution, Logging
