| 摘 要： | 论述了层状极化大地复电阻率正、反演算法。给出了层状极化大地条件下三极和对称四极装置视复电阻率的解析表达式,并引入线性滤波方法实现表达式的求解。正演算例计算结果表明;随着频率的降低,复电阻率相位峰值增大;随着极化层层厚增加,复电阻率虚部平缓变化后连续递增。介绍了递推反演算法的实现过程,从理论模型试算结果看,测深曲线较好地反映了极化层Cole-Cole参数随深度的变化规律,其曲线的首支和尾支趋近于极化层的真Cole-Cole参数,表明了反演计算的可行性。

| Abstract: | The forward and inversion methods about complex resistivity in multi-layer polarized earth are systematically described in this paper.Analytical expression is first given for three-poles and Schlumberger complex resistivity sounding in polarized multi-layered earth,and the complex resistivity is calculated by linear filtering.The forward modeling results show that the peak phase of complex resistivity increases as frequency decreases;the imaginary part of complex resistivity continuously increases after gen... |
