摘　　要：利用综合测井资料,对十红滩铀矿床含矿含水层中隔层、夹层进行物性特征识别,分析其空间展布,讨论隔、夹层与砂岩型铀矿关系及对地浸工艺的影响。认为隔、夹层对层间氧化带砂岩型铀矿的形成和地浸开采有重要影响。A geophysical signature recognition of aquifuge and relatively impermeable interbed in ore-hosting aquifer has been carried out at Shihongtan uranium deposit by using comprehensive logging data. The spatial distribution of above aquifuge and impermeable interbed is discussed, and the relation of these layers to sandstone-type uranium deposit, and their impact to in-situ leach mining technology are discussed. It is suggested that the aquifuge and relatively impermeable interbed bring about significant effect to the formation of interlayer oxidation zone sandstone-type uranium deposit, as well as to in-situ leach mining of the deposit.
