Abstract: ased on the recent research data related to deep-seated fluids in sedimentary basins, three kinds of fluids can be classified: Crustal-derived hydrothermal fluids, hydrocarbon source rock-related fluids and mantle-derived fluids. In this study, the crustal-derived hydrothermal fluid activities related reservoir beds of the Tarim Basin are discussed, and their identification features are summarized. Combined with data from the Wilcox Basin in the Gulf of Mexico, the Norway and Junggar Basins, isotopic characteristics of the hydrocarbon source rock-related fluids and their implication in reservoir beds are addressed. Rift basins in eastern China and the Huangqiao CO2 reservoir are used to constrain the features of mantle-derived fluids. The role of mantle-derived CO2-rich fluids in the alteration of sandstone of the Huangqiao reservoir bed is discussed as well.
