Quantitative Analysis of Light Hydrocarbons in Source Rocks by Gas Chromatography

  • 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.
