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.

Claim (Index 9):
A device for determining thermal maturity of oil source rocks by total scanning fluorescence, the device comprising:\n a first unit for testing by total scanning fluorescence, an organic solution of the extract of a series of oil source rock samples collected at different depths, wherein, the concentration of the extract in the organic solution is 0.01 ppm to 1000 ppm; thus obtaining the TSF Intensity parameter and TSF R1 parameter of the total scanning fluorescence spectrum, wherein the TSF Intensity is the value of the maximum fluorescence intensity in the total scanning fluorescence spectrum, and the TSF R1 is the ratio of the intensity of the fluorescence spectrum at 360 nm to the intensity of 320 nm with an emitting light at 270 nm; a second unit for 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; wherein the identification criterion lies in that the initial position of the stage of initial oil generation is set when the increase of the TSF R1 parameter becomes leveling, the initial position of the stage of major oil generation is set when the TSF R1 parameter turns from leveling to decreasing, and the initial position of the stage of major gas generation is set when the TSF Intensity parameter turns from leveling to decreasing; and a third unit for establishing the relationship between the TSF Intensity parameter and/or the TSF R1 parameter with 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.
