The present invention a method for determining the gas saturation of a tight reservoir. The method comprises the steps of: determining the pore size distribution of the tight reservoir rock sample, and calculating the free water saturation; calculating the water-membrane water saturation; calculating the corner water saturation; calculating the gas saturation of the tight reservoir rock sample according to the following equation:=100&#x2212;

Method for determining gas saturation of tight reservoir

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 Rparameter 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 Rparameter 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.
