瑞雷面波测深法在二连盆地乌兰察布坳陷铀资源勘探中的应用研究

Applied research of Rayleigh wave sounding method in uranium resources exploration in Wulanchabu depression of Erlian Basin

针对二连盆地乌兰察布坳陷铀资源产出的埋藏较浅、含矿目的层与围岩波阻抗差异小的特点,探索了瑞雷面波测深法进行层位划分的可能性。研究表明,瑞雷面波测深法可以获得目的层的层位信息,可以弥补反射波地震测深应用的不足,对浅层沉积层定位具有积极的指导意义,能够指导区域地质找矿工作。

According to the characteristics of shallow bury depth of uranium resources, and smart difference of wave impedence between surrounding rock and ore-bearing target layer in Wulanchabu depression of Erlian Basin, this paper discusses the possibility of the Rayleigh wave sounding method for shallow strata detecting. Study shows that Rayleigh wave sounding method can get the horizon information of target layer, which can make up the shortage of the reflection wave seismic sounding application, and also has positive guiding significance for shallow strata sedimentary positioning and regional geological prospecting work.
