摘要
国内外许多砂岩型铀矿产于含油气盆地,油气参与砂岩型铀成矿作用越来越受到人们的重视;沉积盆地控制着油气田和砂岩型铀矿床的分布,多数盆地总体形成内部油气-边部铀矿、下部油气-上部铀矿的分布规律。文章认为油气藏与砂岩铀矿床相互联系的储集层系统及盆地有机/无机成因流体是两者同盆共存的物质基础,吸附作用和还原作用是油气参与砂岩型铀矿成矿的两种主要作用方式,重力流驱动的含铀流体与油气成藏过程中油气扩散形成的烃类流体相互混合是铀成矿作用的主要动力学机制,构造则是两种流体联系的纽带;油气与铀矿相互共生、相互作用,为"以铀找油"和"以油找铀"提供了基础。根据油气与铀的成因联系,结合石油勘探开发资料,提出利用油气田资料"二次开发"寻找砂岩型铀矿的思路和方法。利用油气田资料来寻找砂岩型铀矿,可节约大量勘探资金,提高油气田经济效益,经济价值高。
Much domestic and foreign sandstone-type uranium deposits occur in oil gas basins. Incorpora-tion of oil gas with sandstone-type uranium mineralization attracts more and more attention. The sedimen-tary basins control distribution of the oil and gas field and the sandstone-type uranium deposits. In general the distribution pattern of oil gas and sandstone-type uranium mineralization in most basins is that oil gas occurs at inner part and uranium about edge or lower part oil gas and uranium upper part in the basins. The interconnected reservoir systems between oil gas reservoir and sandstone uranium deposits and the or- ganic/inorganic fluid flow are the basic material basis for their co-existence in basins. Sorption and reduc-tion were the two main mechanisms for incorporation of oil gas with sandstone-type uranium mineraliza-tion. The gravity-driven uranium-bearing fluid mixed with hydrocarbon fluid formed by the oil gas diffu-sion during the hydrocarbon generation and accumulation process that is the main dynamic mechanism of the uranium mineralization. Structure is the link of the two fluids. Symbiosis of oil gas and uranium and their interaction provides the foundation for prospecting uranium by oil gas or prospecting oil gas by urani-um. Combined with data of petroleum prospecting and exploitation philosophy of “use data of oil gas field to prospect uranium” is put forward. In this way much capital will be saved.
