| 摘 要： | 利用水平电偶源激发的电磁场，提出了直接精确计算全区视电阻率的方法．计算和分析结果表明，该方法的结果在远区等价于卡尼亚电阻率，在近区和过渡带则明显地改善了卡尼亚电阻率的非波区场畸变，从而能更好地接近基底的真电阻率，更形象地反映了地下介质的垂向电性变化．

| Abstract: | This paper presents a method to compute directly and accurately the full-wave apparent resistivity by using the electromagnetic field data from horizontal electric diapole.The calculation results and analysis show that in far-field area the results are equal to Cagniard resistivity,but in near-field area and transient area, the results have greatly improved the strong distortion of Cagniard resistivity. So the results can reach the true resistivity and indicate the changing features of conductivity of subsurface much better than Cagniard resistivity does. |
