| 摘 要： | 将烃源岩石使用低沸点溶剂密封抽提,采用高分辨毛细柱进行色谱分析,在选定的色谱条件下,能获得C5~C30的烃类物质信息。选用色谱内标法对C6~C15轻烃组分进行定量分析研究,由于轻烃组分的不同挥发性,以1-己烯作内标物来控制C6~C7烃类物质的定量,以1-壬烯作内标物来控制C7~C15(含C7)烃类物质的定量。结果表明,方法加标回收率大于85%,重复性分析相对误差小于10%。方法稳定可靠,能准确提供烃源岩中C6~C15轻烃的定量数据,有效应用于油气田勘探资源量评价中。

| Abstract: | With a low boiling-point solvent,hydrocarbons in source rock samples was extracted in a closed pot and analyzed by gas chromatography with high resolution capillary columns.The results showed that the information of C5 to C30 could be obtained by this method.The gas chromatographic internal standard method was used in quantitative analysis of C6～C15 with internal standard of 1-hexene for quantification of C6 to C7 and 1-nonene for C7 to C15(including C7) with high recovery(>85%) and good reproducibility(with RE<10%).The method is stable,reliable,and has been applied to the oil and gas exploration and evaluation. |
