NEUTRON ACTIVATION LOGGING TECHNIQUE FOR DETERMINING THE CaF_2 CONTENT IN ROCKS IN DRILLS AND ITS APPLICATION

摘要:

Abstract:

The neutron activation logging technique which is an advanced nuclear logging technique was discussed in this paper. The technical requirements and conditions for determining the fluorite(CaF_2) content of rocks in drills, the factors which influence the use of the technique and the correction approaches were described in detail. The calculations of the CaF_2 content in the rocks from the measurements, the sensitivity of the logging, the precision and accuracy of the measurements were discussed as well.Two ...
