基于直流电场中球及椭球的电位函数及柯尔-柯尔张驰模型,导出地下埋藏体积极化球和椭球体井中视复电阻率解析表达式。镜象法实、虚球对地下测点作用不对称的问题,用多个含不同宗量勒让得函数的几何因子逐点迭加来解决。井中视复电阻率谱受地面影响小,曲线形态比地面谱更简单,更利于区分异常源的性质;其方位测量剖面曲线可判断极化体赋存位置。
Based on the potential function of the ball and the ellipsoid in DC electric field and the Cole-Cole relaxation model, the analytic expression of apparent apparent resistivity in the buried buried volume polarization sphere and the ellipsoid well is deduced. Mirror law, the virtual ball on the underground measuring point of the role of asymmetry, with a number of different factors Lele Jean function of the geometric factors by point to solve. The apparent resistivity spectrum in borehole is less affected by the ground and the curve shape is more simple than the ground surface spectrum, which is more conducive to distinguish the nature of the anomaly source. The azimuth measurement profile curve can determine the location of the polar body.
