Abstract
A device and method of determining thermal maturity of oil source rocks by total scanning fluorescence including testing the organic solution of the extract from a series of oil source rock samples collected at different depths by total scanning fluorescence; building a model for interpretation of the oil source rock maturity according to the variation with depth of the TSF Intensity parameter and the TSF R1 parameter obtained by total scanning fluorescence, and identifying the stage of initial oil generation, the stage of major oil generation and the stage of major gas generation; and establishing the relationship between the TSF Intensity parameter and/or the TSF R1 parameter with the existing characteristic parameters that quantitatively characterize the maturity of oil source rocks, thereby accomplishing the analysis and determination of the maturity of the oil source rocks.
