Abstract: A series of solid-state 13C NMR experiments for Gansu oil shale were conducted with the BRUKER AVANCE III 400 WB spectrometer analyzer. By using cross-polarization magic angle spinning (CP/MAS) technology and total sideband suppression (TOSS)，a high-resolution spectrogram was obtained. Analyzing the relationship between generation potential and total organic carbon，aliphatic carbon，potential carbon showed that potential carbon was the primary factor in determining generation potential. Comparing the data of dry distillation experiment and solid-state 13C NMR indicated that the carbon of toal organic carbon transformed to oil in the experiment was related to potential carbon. Theoretical analysis of tansformation of organic carbon into oil agreed with dry distillation experiment.

摘要： 在BRUKER AVANCE III 400 WB波谱测定仪上进行了甘肃油页岩的固态碳13核磁共振（13C NMR）实验。应用交叉极化和魔角自旋（CP/MAS）技术，同时采用了旋转边带全抑制技术（TOSS），获得了甘肃油页岩的高分辨的13C NMR波谱图。据此分析了油页岩的生油潜力与总有机碳、脂肪族碳、油潜力碳之间的关系，结果表明，油潜力碳是决定生油潜力的主要因素。通过将含油率测定实验与固态13C NMR实验的结果相比较，发现含油率测定实验中转化为油的碳占总有机碳的分数与油潜力碳相对应。通过对有机碳转化为油的部分进行理论分析，发现分析的结果与含油率测定实验得到的转化为油的碳的分数相符合。13C NMR实验、含油率测定实验及理论分析较好地反映了甘肃油页岩的生油潜力。
