利用先进的测试技术对5种不同地区的油页岩干酪根分别进行XRD、13C NMR与FT-IR分析，获得重要结构信息。通过XRD检测分析，确定5种干酪根以长程无序的聚合状态存在。采用13C NMR技术表征出干酪根的碳原子化学结构，并获得碳骨架结构的18个重要参数。最后利用 FT-IR 技术对干酪根官能团进行定性分析，与13C NMR实验结果互相验证，得到干酪根化学结构的详细信息。结果表明：油页岩干酪根脂碳结构最多，高达60%～90%。其中又以亚甲基碳为主，有77%～90%，且多数为直链结构，脂环或支链结构较少。芳碳结构除桦甸以单环为主外，其余均为单环和多环结构并存，其中多环结构以迫位缩合为主。氧结构总体以碳氧单键（醇、酚或醚基）和CO两种形式存在，其中羧基类CO多于羰基类CO。变质程度低的干酪根中存在较多CO，而高变质程度的干酪根则以碳氧单键C O为主。

Five different oil shale kerogens were analyzed with advanced testing techniques (XRD,13C NMR and FT-IR) to obtain important structural information. The long-range disordered state of aggregation was also confirmed by XRD. Using13C NMR spectroscopy, 18 characteristic parameters of carbon skeleton structure were obtained. Detailed information about the chemical structure of kerogen was obtained through verifying the results of13C NMR experiments with the qualitative analysis of kerogen groups made by FT-IR technique. The aliphatic structure of oil shale kerogen was up to 60%—90%, with the methylene carbon occupying the dominant position of 77%—90%, and most of the aliphatic structure were straight-chain while less alicyclic or branched chain. In addition to Huadian oil shale with a monocyclic aromatic carbon structure, the other four oil shale kerogens were co-existing monocyclic and polycyclic rings, with the latter mainly peri-condensed. The oxygen structure was CO (alcohol, phenol, ether) and CO, and carboxyl class was more than carbonyl class CO. More CO in kerogen was due to a low degree of metamorphism, while a high degree of metamorphism resulted in more CO.
