| 摘 要： | 砂岩型铀矿已经成为中国非常重要的铀矿类型,不少资料表明,在含油气盆地中,砂岩型铀矿与油气藏的关系密切,大型沉积盆地不但是油气田勘探的重要靶区,也是寻找砂岩型铀矿的重要方向。在地球物理勘探中,每种地球物理方法都有其应用条件和优缺点,寻找一种快速经济有效的适合铀矿勘查手段显得非常重要。高频电磁法是一种野外数据采集设备轻便、观测时间短、可快速密点连续测量的方法。本文针对砂岩型铀矿的特点,在应用该项技术进行铀矿勘查方面进行了一系列研究,自行开发了针对性的二维反演软件,有效提高了测量分辨率和地质解释的精度。本文介绍了高频电磁法在寻找砂岩型铀矿勘探方面的应用实例与效果,提出了以后开展类似工作的建议。

| Abstract: | Sandstone-type uranium deposits have become a very important type of uranium deposits in China. Many data show that the sandstone type uranium deposits in petroliferous basins are closely related with oil and gas reservoirs. Large-scale sedimentary basins are not only important target areas of oil and gas exploration, but also an important direction of searching for sandstone-type uranium deposits. In geophysical exploration, each geophysical method has its application conditions, advantages and disadvantages. It is very important to find a fast and effective method for uranium exploration. The high-frequency electromagnetic method has portable equipment during field data acquisition, with short observation time, capable of fast dense point continuous measurement. We focused on sandstone type uranium deposits to perform a series of research on this technique in uranium exploration. By our independent efforts, we developed two-dimensional inversion software which can effectively improve the resolution and precision of geological interpretation. In this paper, we present the application case and results of high-frequency electromagnetic method in the exploration of sandstone-type uranium deposits. |
