Abstract

Summary

The prompt gamma neutron activation (PGNAA) borehole logging system used for determining salinity with the employment of D-T neutron generator, two He-3 thermal neutron detector and LaBr3 gamma ray detector has been proposed. Based on characteristic gamma ray counts of chlorine and the formation porosity, the salinity is calculated. The relationship between thermal neutron counts ratio and porosity is less affected by salinity. The new logging instrument was applied in the oil field and the salinity calculated in different depth, which is very benefit for mineral and petroleum exploration.
