The qualitу of the logging data is the key to the prediction of collectors’ geological parameters. Logging data have high continuity and vertical resolution. It’s already proved the efficiency using logging datas for predicting geological and geochemical parameters, including for predicting total organic carbon (TOC). In this article, based on well studying of C region in Ordos basin, log normalization was carried for AC, DEN, RT and CNL. In the process of normalization, C7-2 layer of the upper Triassic series was selected as the calibration formation and the A well was selected as the calibration well. The result shows that, on the one hand, log normalization can effectively reduce systematic errors of logging datas and enhanced the efficiency of TOC prediction with the help of logging data.
