Based on the discussion on the principle of density - logging, this paper analyses far - gamma gamma rate, near - gamma gamma rate and density - logging curve respectively, and discusses far - gamma gamma rate near - gamma gamma rate and density variation caused by radioactive anomalies, and preliminarily interprets factors that could lead to the variation of density - logging curve of radioactive anomalous layer, thus explaining the reason why density - logging curve changes at the radioactive ore - layer in northern ordos basin, finally, an empirical formula for revising the distortion of density - logging curve has been established
摘要本文概述了密度測井原理，分別對長源距計數率、短源距計數率及密度曲線進行分析，對由於放射性異常引起的長源距計數率、短源距計數率及密度變化情況進行了討論，初步解釋了放射性異常層位密度曲線的變化因素，說明了鄂爾多斯盆地北部地區密度測井曲線在放射性礦段的變化原因。 -
