Calibration of magnetotelluric sounding based on resistivity logging curves

摘要: 大地电磁测深曲线畸变的校正是大地电磁勘探中的重要问题。通过在D盆地的电阻率测井曲线与大地电磁测深平移方式校正前后的反演测深曲线相比较,构造变换函数,实现了测井曲线对大地电磁测深曲线的标定。经过该技术改进的大地电磁反演结果与验证钻孔极为吻合,结合钻井、地震、重力、磁法资料进行综合分析,有效地揭示了D盆地的构造特征。Abstract: The distortion correction of magnetotelluric sounding curves is critical to magnetotelluric exploration. Based on the comparison between the resistivity logging curves of basin D and the basin's inversed sounding curves before and after being corrected through magnetotelluric sounding translation, this study constructed a transformation function and calibrated magnetotelluric sounding curves using logging curves. The magnetotelluric inversion results improved using the calibration technology proposed in this study are highly consistent with the verification boreholes. Finally, this study effectively revealed the structural characteristics of basin D by combining drilling, seismic, gravitational, and magnetic data.
