摘要
Abstract
Based on the principle of density logging ,this paper first disserted the reason of the distortion occurred in density data ,and pointed out that the superposition of long and short spacing data caused by γradiation in ore seam is the reason for the curve distortion ,and then raised a set of method which meas‐ure the density data twice to minimize the effect caused by the superposition and adjust the density curve in ore seam ,the method established an automatic calculate model which fits calculating ore seam density in sandstone uranium exploration. By comparison and validation on data acquired in Shihongtan uranium deposit situated in Turpan‐Hami basin ,Xin Jiang ,it was finally found that the density after correction of the calculated density fits the real density better. Therefore it can be concluded that corrected curve data is very important in recognizing rocks correctly and calculating uranium reserves.关键词
