Abstract
A five-point deconvolution method for quantification of uranium ores by energy spectrum logging disclosed by the invention refers to: carry out γ spectrum logging along the borehole to obtain logging curves in multiple energy zones, using these logging curves and energy spectrum features, inversion calculate the distribution of uranium content along the borehole; the main features are: first, realize the subdivision interpretation of layered strata; second, realize multi-element stripping for energy spectrum logging; third, realize subdivision interpretation by the five-point deconvolution methods; fourth, on-site uranium ores quantification under fast spectral logging conditions can be realized; the invention also discloses two types of algorithm flows of “first stripping, then subdividing” and “first subdividing, then stripping” and the formula for solving the uranium/thorium/potassium content of the unit layer.
