摘要
可地浸砂岩型铀矿多数赋存于产油气盆地,并与油气关系十分密切。本文通过对可地浸砂岩型铀矿的成因分类、与油气藏的关系及与气藏异同点的分析对比,总结了几种典型油气藏上方的放射性异常模式。以二连盆地可地浸砂岩型铀矿与油气藏的客观相伴关系为例,在鄂尔多斯盆地进行了应用试验,取得了一定效果。因此,利用铀油相伴关系,在油气勘探中注意寻找铀矿(化)床,在铀矿(化)床周围的有利构造部位加强油气勘探是十分重要的。
ISl-amenable sandstone-type uranium deposits occur mostly in oil-and gas-hosting basins, and are closely associated with oil and gas. Based on the genetic classification, the analysis of the relation between uranium deposit and oil and gas accumulation as well as the analysis and comparison of the similarities and differences between uranium deposits and oil and gas accumulations, several typical models of radioactive anomalies above oil and gas accumulations have been summarized. Application tests have been performed in Ordos basin taking the ISL-amenable sandstone-type uranium deposits in Erlian basin as an example, and certain effects have been obtained. So, it is important to pay attention to search for uranium deposits during oil and gas exploration, and to strengthen oil and gas exploration at favourable sites around uranium deposits by using the association relation between uranium and oil.
