利用轻烃指纹进行油气岩源对比分类研究的主要困难在于岩石轻烃的获得,利用某低沸点溶剂对岩石进行密封抽提,并采用高分辨率毛细柱进行色谱分析,实验结果表明,本方法能获得C5至C31以上的烃类物质信息,其中C5至C10之间的可分离出100多个烃类物质,能很好地满足油气地质研究的需要,是进行油气岩源三位一体研究较理想的技术支持方法。

The most difficult thing in oil-gas-source rock correlation with fingerprints of light hydrocarbons is obtainment of light hydrocarbon extracted from source rocks. With a low boiling-point solvent, rock samples was extracted in a closed pot and analysed by high resolution gas chromatography using capillary columns. The results showed that this method could give out information of C5 to C31+, and could discrimanete over 100 hydrocarbons between C5 and C10 to satisfy the study of petroleum geology. It is ideal for correlation among oil, gas and source rocks.
