Review of deep fluids in sedimentary basins and their influence on resources, with a focus on oil and geothermal exploitation

Deep fluid activity is widespread in large oil-gas basins around the world. fluids, as links between internal and external factors of a basin, run way organic-inorganic interactions through formation aggregation. Herein, identification characteristics deep fluids sedimentary well their influence on reservoir geothermal resource are summarized. The identified from three aspects, including mineral composition, inclusions, geochemical characteristics. effects activities manifested two key aspects matter energy. As for effects, can improve primary productivity carry abundant inorganic hydrogen, which contributes to improving hydrocarbon hydrogenation. energy heat promote mature evolution organic oil gas. During this process, heating will cause oil-generation window depth source rocks become thinner, it also generate very high pressure, discharge hydrocarbons formed by rocks. Furthermore, directly form volcanic rock reservoirs. And another manifestation geothermal. thermal hot dry rocks, most important existing resources. geological exploration should be supported further geophysical research.
