Abstract: The coexistence and enrichment in the same basin of oil, gas, coal and uranium are universal, and the origin and distribution relative to each other closely. Organic-inorganic interactions is the genetic mechanism and connection link of the multi-energy resources coexistence and mineralize. The strong absorption, reducing environment, complexation  and other functions from organic oil, gas and coal played an important and positive role in accumulating of inorganic uranium. Inorganic component plays an important catalysis in the process of hydrocarbon generation. Uranium has good ligancy due to its special atomic structure, thus it has excellent characteristic of complexing catalysis and oxidation/reduction. Uranium may offer energy to living beings to keep their propagation and vegetation, lead erupting multiply, and favor the formation of high quality source rocks. Uranium can promote the generation of liquid hydrocarbon in advance, increase the total hydrocarbon production of hydrocarbon source rock at lower temperature, meanwhile, it can prevent organic matter from overmature to preserve hydrocarbon produced at high temperature well. Uranium should be one of the inorganic accelerating factors of the hydrocarbon generation. The generation and migration of such a small amount of hydrocarbon can turn the host reservoir with good poroperm characteristics at eogenetic stage into lipophilicity in a wide rage, and it provides advantage conditions for migration and accumulation of late large scale generated hydrocarbons. It is possible that even though the dense reservoir also become a large-scale commercial hydrocarbon reservoir/field.
