【摘要】 多种能源(油气煤铀)协同勘查盆地分析,是通过研究盆地地质因素,时空展布和控制因素,查明赋矿地质条件和多种能源矿产之间的内在联系。油气藏和砂岩型铀矿在空间展布、成矿时代、地化特征、成矿作用等方面存在着关联。油气与砂岩型铀矿床的共生/伴生是基于两者储层、盆地内流体及有机质的作用的相互联系。矿源物质聚集及运移、油气水还原障的形成和铀在油气还原障中沉淀富集成矿是油气在铀成矿过程中的作用,大规模油气耗散作用是铀矿超常富集的主要原因,成岩作用与油气侵位对砂岩铀成矿具有约束作用。由沉积盆地内两者的紧密联系,更好的利用油气和铀矿勘探的地质资料指导勘探和找矿,下一步应借助更多的研究手段完善"同盆共存"的成矿机制。更多还原

【Abstract】 The multi-energy(oil, gas, and uranium) collaborative exploration basin analysis is to investigate the intrinsic relationship between the ore-bearing geological conditions and various energy minerals by studying the geological factors, time-space distribution and control factors of the basin. Oil and gas reservoirs and sandstone-type uranium deposits are related in terms of spatial distribution, metallogenic age, geochemical characteristics, and mineralization. The symbiosis/association of oil and gas and sandstone-type uranium deposits is based on the interrelationship between the reservoirs, fluids and organic matter in the basin. The accumulation and migration of mineral resources, the formation of oil and gas water reduction barriers and the precipitation of uranium in oil and gas reduction barriers are the role of oil and gas in uranium mineralization. Large-scale oil and gas dissipation is the main reason for the extraordinary enrichment of uranium deposits. The diagenesis and oil and gas emplacement have a binding effect on sandstone uranium mineralization. From the close relationship between the two in the sedimentary basin, the geological data of oil and gas exploration and uranium exploration can be better utilized to guide exploration and prospecting. The next step should be to improve the mineralization mechanism of "coexistence with the same basin" with more research methods.更多还原
