Beschreibung
Zusammenfassung:	The invention provides an identification method for reservoir fluid properties. The identification method comprises following steps: analyzing sandstone samples of a target reservoir segment to be identified in a single well in order to first carbon isotope data forming sandstone samples; processing first carbon isotope data in order to obtain second carbon isotope data in accord with the standard of carbon content; setting up an identification chart for reservoir fluid properties according to second carbon isotope data; and identifying fluid properties of the target reservoir segment of tight sandstone to be identified in the single well based on the identification chart for reservoir fluid properties. The technical scheme of the identification method for reservoir fluid properties helps to significantly improve accuracy rate for identification of fluid properties of the target reservoir segment to be identified and deepen the understanding of gas reservoir so that great application value is obtained.
