概述在加拿大和世界各处,γ能谱测井日益成为铀矿勘探和评价的重要方法。其主要原因是,与金刚石岩心钻探相比,冲击钻价格比较低,而且γ测井分析所代表的岩石体积比岩心分析的体积要大得多。通过今后进一步的改进,可使测量仪器和测量方法更可靠,并且可使测量结果的精确度得到改善。 Overview In many parts of Canada and around the world, γ-ray logging is increasingly becoming an important tool for uranium exploration and evaluation. The main reason for this is that the impact drill is relatively inexpensive compared to diamond core drilling and the volume of rock represented by gamma log analysis is much larger than that of core analysis. With further improvements in the future, the measuring instruments and measuring methods can be made more reliable and the accuracy of the measurement results improved.
