Gamma logging is the fundamental method for quantitatively determining uranium content of mineralized intervals in boreholes. The U-Ra equilibrium in a certain sandstone-hosted uranium deposit has been severely disrupted. To investigate the impact of Ra-rich sections (mineralized intervals where the equivalent uranium grade derived from radium is ≥ 0.010 0% but the uranium grade is<0.010 0%) on log interpretation and U-Ra equilibrium correction results, the uranium and radium content analysis results of permeable ore samples were systematically studied. The results show that: for samples with a uranium grade≥0.010 0%, the weighted average uranium grade is 0.042 7 %, the weighted average U-Ra equilibrium coefficient is 0.615, and the coefficient of variation is 1.041; for samples with an equivalent uranium grade derived from radium≥0.010 0%, the weighted average uranium grade is 0.029 5%, the weighted average U-Ra equilibrium coefficient is 0.890, and the coefficient of variation is 3.785. Ra-rich sections will significantly increase the deposit's U-Ra equilibrium coefficient, increase the orebody thickness, and decrease the deposit's uranium grade. Gamma logging cannot identify and remove Ra-rich sections. Consequently, neither the log interpretation results nor the U-Ra equilibrium correction results objectively reflect the orebody's spatial position, grade and thickness. The estimated resource quantity is also inaccurate.

伽马测井是在钻孔中定量确定矿段铀含量的基本方法。某砂岩型铀矿铀镭平衡被破坏,为研究偏镭矿段(即镭的当量铀质量分数≥0.010 0%,而铀质量分数<0.010 0%的矿化段)对测井解释及其铀镭平衡修正结果的影响,系统研究了可渗透矿样的铀、镭含量。结果显示:对于铀质量分数≥0.010 0%的样品,加权平均铀质量分数为0.042 7%,铀镭平衡系数加权平均值为0.615,离散系数为1.041;对于镭的当量铀质量分数≥0.010 0%的样品,加权平均铀质量分数为0.029 5%,铀镭平衡系数加权平均值为0.890,离散系数为3.785。研究表明,偏镭矿段的存在会显著提高矿床的铀镭平衡系数、增大矿体厚度,并降低矿床铀品位。伽马测井无法识别并剔除偏镭矿段,测井解释和铀镭平衡修正结果均不能客观反映矿体的空间位置、品位和厚度,估算的资源量也不准确。

伽马测井是在钻孔中定量确定矿段铀含量的基本方法。某砂岩型铀矿铀镭平衡被破坏,为研究偏镭矿段(即镭的当量铀质量分数≥0.010 0%,而铀质量分数<0.010 0%的矿化段)对测井解释及其铀镭平衡修正结果的影响,系统研究了可渗透矿样的铀、镭含量。结果显示:对于铀质量分数≥0.010 0%的样品,加权平均铀质量分数为0.042 7%,铀镭平衡系数加权平均值为0.615,离散系数为1.041;对于镭的当量铀质量分数≥0.010 0%的样品,加权平均铀质量分数为0.029 5%,铀镭平衡系数加权平均值为0.890,离散系数为3.785。研究表明,偏镭矿段的存在会显著提高矿床的铀镭平衡系数、增大矿体厚度,并降低矿床铀品位。伽马测井无法识别并剔除偏镭矿段,测井解释和铀镭平衡修正结果均不能客观反映矿体的空间位置、品位和厚度,估算的资源量也不准确。

Gamma logging is the fundamental method for quantitatively determining uranium content of mineralized intervals in boreholes. The U-Ra equilibrium in a certain sandstone-hosted uranium deposit has been severely disrupted. To investigate the impact of Ra-rich sections (mineralized intervals where the equivalent uranium grade derived from radium is ≥ 0.010 0% but the uranium grade is<0.010 0%) on log interpretation and U-Ra equilibrium correction results, the uranium and radium content analysis results of permeable ore samples were systematically studied. The results show that: for samples with a uranium grade≥0.010 0%, the weighted average uranium grade is 0.042 7 %, the weighted average U-Ra equilibrium coefficient is 0.615, and the coefficient of variation is 1.041; for samples with an equivalent uranium grade derived from radium≥0.010 0%, the weighted average uranium grade is 0.029 5%, the weighted average U-Ra equilibrium coefficient is 0.890, and the coefficient of variation is 3.785. Ra-rich sections will significantly increase the deposit's U-Ra equilibrium coefficient, increase the orebody thickness, and decrease the deposit's uranium grade. Gamma logging cannot identify and remove Ra-rich sections. Consequently, neither the log interpretation results nor the U-Ra equilibrium correction results objectively reflect the orebody's spatial position, grade and thickness. The estimated resource quantity is also inaccurate.
