摘　　要：A combination of Soxhlet extraction, column chromatography and INAA with GC and GC- MS was used in this work for the study of the abundance patterns of 36 trace elements and their correlation in nearly 100 samples of crude oil and organic materials extracted from oil- forming source rocks from 10 main Chinese oilfields. The low V/Ni ratios of 0.01 to 0.3 state the oil- forming continent environment. The geochemical significance hinted from other trace element abundances is also briefly discussed.A combination of Soxhlet extraction, column chromatography and INAA with GC and GC- MS was used in this work for the study of the abundance patterns of 36 trace elements and their correlation in nearly 100 samples of crude oil and organic materials extracted from oil- forming source rocks from 10 main Chinese oilfields.
