Abstract: The HyLogger core scanning system is one of the most efficient scanning systems for obtaining high spectral data of drill core in recent years, it has been widely used in metal mineral resources successfully.For the spectral reflectance of black shale gas core is very low and the spectral characteristics are not obvious, this paper proposed two reasonable high spectral data collection methods which based on the improvement of the measurement system and the core data.This method effectively improves the spectral reflectance of the black shale gas core and obtains a high quality core spectral data.The use of the HyLogger core scanning system will play an important role in the measurement of shale gas core.
