有机-无机能源矿产相互作用及其共存成藏(矿)

油、气、煤、铀同盆共存富集存在普遍，其形成、分布关联密切；有机-无机相互作用是多种能源矿产共存成藏(矿)的成因机理和联系纽带。有机油、气、煤所提供的强大的吸附作用、还原环境和络合作用等，对无机铀的沉淀、富集和成矿具有重要的积极作用。在烃类生成过程中，无机组分具有重要的催化作用，如铀因其特殊的原子结构，具有独特良好的配位性能，因而具有良好的络合催化及氧化还原催化特性。铀的存在，为生物的繁殖提供能量，使之勃发繁衍，利于优质烃源岩的形成；可导致烃源岩在温度较低阶段液态烃提前生成，并使总烃产量增加；同时在高温阶段可减缓有机质过度成熟，利于所生烃类的保存。铀应为低(未)熟油、气生成的重要因素之一。这种少量烃类的提前生成和运移，可使成岩早期阶段孔渗性能良好的储层较大范围变为亲油性，为后期大规模生成的油气运移和成藏创造了有利条件，使得即使是致密储层也有形成大规模商业油气藏(田)的可能。

Organic-inorganic energy minerals interactions and the accumulation and mineralization in the same sedimentary basins

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.
