本文介绍了3种不同地质环境中应用钻孔地球物理测井的情况。讨论的3项实例研究是评价纳米比亚奥兰治蒙德附近sendelings Drift冲积金刚石矿床,马里西部Sadiola金矿体,以及博茨瓦纳中央地区金伯利岩筒。本文说明钻孔地球物理测井的用途并不局限于石油工业,石油工业中使用的定量方法也可以推广应用于任何矿床。本文描述的方法对边缘矿体特别有用,可迅速地了解矿床的三维分布。
This article describes the application of borehole geophysical logging in three different geological settings. The three case studies discussed were to evaluate the sendelings Drift alluvial diamond deposit near Orange in Namibia, the Sadiola gold deposit in western Mali, and the kimberlite barrels in central Botswana. This article shows that the use of borehole geophysical logs is not limited to the oil industry and the quantitative methods used in the oil industry can also be extended to any deposit. The method described in this paper is particularly useful for edge orebodies to quickly understand the three-dimensional distribution of deposits.
