摘要
将倒置荧光显微镜、反射式显微物镜、微透镜、光纤和荧光分光光度计等有机地融合为一体,建立了测量单个油气包裹体的紫外可见显微荧光光谱装置,该装置无需对显微镜做任何技术改造。实测了伏4井(泉三段,吉林油田)单个油气包裹体的紫外可见显微荧光光谱。通过250 nm激发下的荧光光谱定性地推测油气包裹体中古油所含芳烃主成分,结果表明液态油气包裹体的重质烃相对含量比气液包裹体多。通过365 nm激发下的荧光光谱计算了油气包裹体的色度坐标,克服了人眼判断颜色的主观性。同一储层单个油气包裹体的紫外可见显微荧光光谱及色度表明该储层在二期充注时可能有两个成熟度不同的母源。
Abstract
An experimental setup is established for measuring ultraviolet-visible(UV-VIS) micro-fluorescence-spectra of single oil inclusion by integrating elements, such as inverted microscope, reflecting microscopic objective, micro-lens, fiber and spectrometer. Any rebuilding to the microscope is not needed to be done. The UV-VIS spectra of single oil inclusion of Fu 4 well(Quan 3 stratum, Jilin oil field)are measured. By fluorescence spectra excited at 250 nm, the main aromatic hydrocarbon composites of the paleo-oil are qualitatively determined. The results show that the relatively heavy hydrocarbons in liquid oil inclusions are more than that in the gas-liquid inclusions. By fluorescence spectra excited at 365 nm, the chromaticity diagram of the oil inclusions are calculated, which overcomes the subjectivity of judging the colors by human eyes. The UV-VIS spectra and chromaticity diagram of the single oil inclusion from same stratum show that there maybe two maternal sources of different maturities when the secondary oil charges.
