电磁波CT在岩溶勘察中有着广泛的应用,本文结合钻孔资料对三叠系大冶组(T_1d)岩溶特征进行统计分析,确定划定该地层岩溶的视吸收系数值,将该参数值用于电磁波CT资料的解译,并通过验证孔对解译结果进行验证。该项研究解决了电磁波CT在岩溶勘察中异常识别的重要问题,为武汉地区三叠系大冶组(T_1d)岩溶勘察提供了重要的指导依据。
Electromagnetic wave CT has been widely used in karst exploration. Based on the borehole data, the karst characteristics of Triassic Daye Formation (T_1d) are statistically analyzed to determine the value of apparent absorption coefficient that defines the karst in this formation. The value of this parameter is used in Electromagnetic wave CT data interpretation, and through the verification hole to verify the results of interpretation. This study solves the important issue of electromagnetic wave CT in the abnormal identification of karst exploration and provides important guidance for the karstification investigation of Triassic Daye Formation (T_1d) in Wuhan.
