在铀矿床的勘探工作中,广泛地采用γ测井和γ取样来确定矿层的厚度和品位。特别是在深钻孔中,γ测井成为唯一的方法。然而,γ测井和γ取样所测得的直接结果仅代表镭含量的分布,并非是铀含量的分布。为了确定铀含量,必须知道矿体的等效平衡系数值(?)。矿体的平衡系数受许多因素的影响。氧化带,原生带,不同深度层位和不同构造部位的铀矿体常常具有明显不同的平衡系数值。因此,在计算等效平衡系数值之前,必须了解整个矿床(矿 In the exploration of uranium deposits, γ logging and γ sampling are widely used to determine the thickness and grade of the ore seam. Especially in deep boreholes, gamma logging becomes the only method. However, the direct results from γ logging and γ sampling represent only the distribution of radium content, not the distribution of uranium content. In order to determine the uranium content, it is necessary to know the equivalent equilibrium coefficient ()) of the ore body. The balance coefficient of ore body is affected by many factors. Oxygen bands, primary belts, uranium ore bodies of different depths and different tectonic positions often have significantly different equilibrium coefficient values. Therefore, it is important to understand the entire deposit before calculating the equivalent equilibrium value
