  1. 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
