利用反射式太赫兹光谱成像系统检测天然岩心和人造岩心切片的表面形貌和原油分布，并与扫描电子显微镜样品分析结果相互补充、相互印证. 由于孔隙和矿物的相间分布，导致不同位置处的太赫兹时域谱幅值具有明显差异，且在孔隙处填入原油后太赫兹时域谱幅值的差异减小. 本实验结合了太赫兹技术这一光学新方法和石油地质相关知识，即可作为油气探测的一种补充方法，又可作为一种新兴实验技术在大学中推广.

The surface morphology and crude oil distribution of natural core and artificial core cuttings are detected by a reflective terahertz spectral imaging system，and the results of sample analysis with scanning electron microscope complemented each other and confirmed each other. Due to the distribution of pores and minerals，the terahertz time-domain spectral ( THz-TDS) amplitudes at different locations have significant differences，and the difference in THz-TDS amplitude decreases after filling the pores with crude oil. This experiment combines the new optical method of terahertz technology and the knowledge related to petroleum geology，which can stimulate students’scientific research interest and cultivate innovative spirit.
