镭氡平衡观测数据的曲线拟合

镭氡平衡系数是地浸砂岩型铀矿储量计算的重要参数之一。通过施工物探参数钻孔,使钻孔中含矿含水层原有的镭氡平衡被暂时破坏。利用伽马测井对孔内镭氡平衡由最初破坏状态恢复到原有动态平衡进行连续观测,并将观测数据进行线性拟合,以便实际工作中开展镭氡平衡系数的研究和评价,为铀资源储量计算提供更准确的参数。

Ra-Rn equilibrium coefficient is one of the most important guidelines of leaching sandstone type uranium deposit parameters calculation.Drilling through the construction geophysical parameters,the original radium radon balance in the borehole is temporarily destroyed.Using gamma logging to observe the equilibrium of radon in the hole from the initial state of destraction to the original state of dynamic balance then fitting the observe data.According to the data above,we can study and evaluate the equilibrium coefficient of radium radon in actual work and provide more accurate parameters for the calculation of uranium resource reserves.
