As the oil can produce fluorescence under UV excitation��by microscopic fluorescence spectroscop- ic method��we quantitatively analyzed the fluorescence spectra of the organic inclusions�� By using its contrast analysis of main peak wavelength and the fluorescence intensity��the main peak wavelength and Q- quotient (red- green quotient)��the characteristics of hydrocarbon reservoirs of Late Paleozoic reservoir in Bashentuo��Tarim Basin were preliminarily studied�� We collected 64 fluorescence spectral data from 32 samples in the studied area�� The a- nalysis results show that there are three oil sources in the Late Paleozoic hydrocarbon reservoirs of Bashentuo��demonstrating the wavelengths are mainly concentrated on three value segments of 439 �� 443 nm��469 �� 472 nm and 498 ��503 nm��which are mixed sources filling in different evolutionary stages�� The precedent two reservoirs come from the Cambrian- Ordovician oil sources with filling up from the bottom up�� The oil source in the later reservoir comes from Carboniferous Bachu Formation charging up and down both directions at the same time��along with the change of evolutionary degree�� Integrating over the organic inclusions captured from different peak wavelengths at the same period��it can be speculated that there are four oil and one gas injection in the research area at least��
