摘要：

油气井中荧光光谱强度及其比值的正向变化梯度和向上趋轻反映了烃类垂向微运移的客观存在。荧光光谱三元图和同步荧光图谱能较好地指示微运移的方向:自深层到地表,λ320nm增加,λ360nm减小;除λ430nm外,各波段均具正向梯度。

Abstract:

The normal variation gradient and the tendency of getting lighter upward of the fluorescence spectrum intensity and the specific value in hydrocarbon well have revealed the existance of hydrocarbon vertical micro migration. Fluorescent ternary diagram and synchronous fluorescence spectrum can properly indicate the direction of the micro migration:from deep strata to surface,R 320 increases,λ 360 nm decreases and every wave band possesses positive gradient with the exception of λ 430 nm

Key words: 3-D fluorescence, synchronous fluorescence, micro migration, migrational direction
