本文采用太赫兹时域光谱技术,研究了5种沉积岩的透射光谱性质.实验显示,不同种类的沉积岩样品在太赫兹波段有明显的峰位位移和相对峰强改变,且各样品由于成分和含量的不同,也在透射太赫兹光谱上表现出了不同的吸收和折射性质.结果表明,太赫兹光谱技术可为鉴别分析沉积岩提供方法与技术支持,继而应用于油气开发和地质勘探领域.
In this paper, the terahertz time-domain spectroscopy was used to study the transmission spectral properties of five sedimentary rocks. The experimental results show that the different types of sedimentary rocks have obvious peak position shifts and relative peak intensity changes in the terahertz band, and due to the composition and content , And also shows different absorption and refraction properties in transmission terahertz spectrum.The results show that terahertz spectroscopy technology can provide methods and technical support for the differential analysis of sedimentary rocks, and then applied to the field of oil and gas exploration and geological exploration.
