摘要: 石油与砂岩型铀矿床的相互关系受到重视。铀矿石与石油中的微量元素(特别是铼、镍、钒等)的共生关系表明它们均可能是深源的,而石油、沥青中的铅、锶、钕同位素示踪与定年则显示原油特别是甲烷与氢气均具有深源特征,砂岩型铀矿的沉淀与成矿是由于深部油气的还原作用的结果。根据石油与铀的特征及成因联系,提出了寻找大油气田的一般准则,即如果有砂岩型铀矿,而其深部中地壳有低速高导层,则可以圈定大油气田的靶区。

Abstract: The relationship between petroleum and sand-type uranium deposit is increasingly concerned. There exists paragenetic relationship between uranium ores and petroleum trace elements (Re, Ni and V, etc.), which indicates that they might be all originated from deep sources. The tracing and dating by Pb, Sr, Nd isotopes in crude and bitumen also prove the nature of deep sources. The deposition and formation of sand-ype uranium ores are related with reduction of hydrocarbon, especially with methane and hydrogen. Based on these deep source features and origin relationship between crude oil and uranium, the general criterion for finding out large oil and gas fields is presented, that is, as long as a sand-type uranium deposit is found with low-velocity and highly-conductive zones in the mid-crust, the target of large oil and gas fields could be delineated.

Key words: crude oil, sand-type uranium deposit, trace element, isotope, mid-crust, deep source, relationship
