摘　　要：HyLogger岩芯测量系统是近年来最高效的获取钻孔岩芯高光谱数据的测量系统之一,其在金属矿产岩芯测量中已获得到了大量成功的应用。对于灰黑色页岩气岩芯而言,其光谱反射率低、光谱特征不明显,本文通过对HyLogger岩心扫描测量系统和岩芯数据两个方面进行分析页岩气光谱数据,并在此基础上提出改进措施,有效的提高了获取的灰黑色页岩气岩芯光谱反射率,获得到了较高质量的岩芯高光谱数据。未来使用HyLogger岩芯测量系统可以在我国页岩气岩芯测量工作中发挥重要作用。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.
