| 摘 要： | 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。

| Abstract: | The expressions of the borehole apparent complex resistivity(BCR)spectra for the buried volume-polarized sphere and spheroid are derived byd.c. electric field theory and the Cole-Cole relaxation model. In theelectrical image method, the asymmetrical influence of the imaginary andreal sphere on subsurface stations can be conducted by means of stackingmulti-geometrical factors which include Legendre function of variousindependent variables. The shape of the spectra curve is simpler than thatof the ground spectra, because of getting smaller ground noise to subsurfacestations, and better for distinguishing sources. The BCR method can beexecuted in azimuthal measurements. The results are useful for thelocalization of a polarized body. |
