摘要
利用太赫兹时域光谱技术研究了混入不同类型和含量原油的油页岩,证明不同混合条件下油页岩的太赫兹时域光谱存在明显差异.结合主成分分析可以快速定性区分油页岩中的原油类型,油页岩的单位厚度幅值衰减系数与原油浓度满足线性关系,拟合后可以定量分析原油的浓度.
Different types and concentrations of crude oils added in oil shale were probed using terahertz time-domain spectroscopy.The difference of the terahertz response was obtained under different conditions.Combined with principal component analysis and linear fitting,terahertz spectroscopy could identify the trace crude oil directly.Qualitative and quantitative analysis models were established.The model could be used to detect unknown shale samples,which was a meaningful innovation for oil and gas exploration.
