生油母质干酪根是石油地质工作研究的重要对象.文章利用衰减全反射(ATR)技术对干酪根样品进行傅里叶变换红外光谱分析,通过与传统压片法谱图进行峰形峰位特征、结构参数比较,表明:① ATR谱具有与压片法吸收谱类似的谱图特征;②与压片法吸收谱相比,ATR谱的吸收强度较弱;③ ATR技术和压片法所获得的红外结构参数具有可比性.由于ATR技术具有无需制样、可以减少水分干扰等优点,因此可以作为干酪根样品快速测试的方法应用于干酪根样品的类型鉴别、热演化程度研究和来源对比.

Oil-generating parent material kerogen is the important target in petroleum geology study. The applicability of attenuated total reflection-fourier transform infrared (ATR-FTIR) technique to analysis of kerogen was discussed in this paper. The spectra of kerogen from attenuated total reflection analysis were compared with those from the same samples but obtained using KBr pellet technique. The results showed that ① the spectra from ATR mode were almost the same as those from pellet absorbance mode, ② band absorbance from the ATR mode was much lower than that from pellet absorbance mode, ③ the FTIR structural parameters obtained from ATR technology and from pellet absorbance method were comparable. As the ATR technology did not need sample preparation, so it could reduce the moisture interference and therefore it was suitable for application in identification of kerogen types, research on thermal evolution degree and source comparison of kerogen.
