Abstract The technique of SPME-GC/MS has been established, which can conduct accurately qualitative and quantitative analysis of C5~C15 hydrocarbons with SPME devices designed by American Supelco Corporation and hydrocarbons standard sample. The authors made a comparative analysis of the SPME-GC/MS technique and headspace in Nanyang depression of Henan, and the results show that oil-gas implications of headspace-methane and SPME indicators are accordant with each other. The test results of surface water and oilfield water in Sichuan basin show that oil and gas properties of the drill hole can be more accurately determined by the SPME-GC/MS spectral features of oilfield water. During the oil-gas geochemical exploration work in the Xifeng oilfield of Ordos basin, the authors found that the anomaly area of total C5~C15 hydrocarbons in SPME technique is coincident with the Chang 8 main oil and gas reservoirs.
