塔然高勒是鄂尔多斯盆地近年来发现的砂岩型铀矿之一.为了研究该区砂体的孔隙度、渗透率、泥质含量等孔渗参数与铀成矿的关系,文章通过采集、分析直罗组下段砂体测井数据,利用校正后的测井曲线,计算砂体的孔渗参数,再对比钻孔样品孔渗参数的分析结果,从而验证计算方法的准确性与可靠性.在准确求取孔渗参数的基础上,研究直罗组下段砂体的孔渗参数的非均质性特征,进而确定该区直罗组下段砂体中,孔渗性由好向差过渡的部位是铀成矿有利部位.
Calculation of Porous Infiltration Parameters and Heterogeneity Characteristics of Sand Body in the Lower Member of Zhiluo Formation in Tarangauler Area
In order to study the relationship between the uranium mineralization and the porosity,permeability,argillaceous content of rocks in the lower member of Zhiluo Formation in Tarangauler area was analyzed,and the logging curve is corrected to calculate the pore permeability parameters,and verify the accuracy and reliability of the pore permeation parameter calculation method by comparing the analysis results of the hole permeation parameters of the borehole samples.On the basis of accurately obtaining the pore permeation parameters,the heterogeneity characteristics of the pore seepage parameters in the lower member of Zhiluo Formation were analyzed,and the physical conditions favorable to uranium mineralization in this area were determined.
