| 摘 要： | 彭阳地区位于鄂尔多斯盆地西南缘,是北方砂岩型铀矿的重点勘察区域。利用现有的地质和测井资料,在前人研究的基础上,针对研究区的二维地震资料进行叠后地震属性分析,描述了砂岩型铀矿的地震响应特征。通过对基于模型的波阻抗反演方法得到的地震波阻抗反演剖面进行精细解释,并在此基础上对本区的砂岩型铀矿的形成环境和富集特征进行分析。通过研究区砂岩型铀矿的含铀储层的预测研究,为目标区铀矿的进一步勘探提供了地球物理方法依据。

| Abstract: | Pengyang area, located in the southwest margin of Ordosbasin, is a key prospecting area for sandstone-type uranium deposits in northern China. In this paper, based on the existing geological and log data and previous research, the seismic response characteristics of sandstone-type uranium deposits were described by post-stack seismic attribute analysis of 2D seismic data in the study area. The seismic wave impedance inversion profile obtained by the model-based wave impedance inversion method was explained in detail, and on this basis, the formation environment and enrichment characteristics of sandstone-type uranium deposits in this area were analyzed. Through the prediction of uranium-bearing reservoir of sandstone-type uranium deposit in the study area, the basis of geophysical method is provided for further exploration of uranium deposit in the target area. |
