Abstract

A new analyzing theory and method of C/O spectrometry logging is reported. Fast neutron enelastic scattering γray spectra(256 channels) were acquired in borehole by NaI(Tl) detector. The enelastic scattering γray from major elements C, O, Si, Ca, Fe, etc. have the fractions of mixed enelastic spectrum in formation respectively. Because F factor is the same for identical formation, then the ratio of yield of C to O, the ratio of weight percent of C to O, and the ratio of atoms C to O could be found, and the corresponding ratio of Ca to Si was found.
