| 摘 要： | 电法勘探中不同的视电阻率定义可以带来不同的反演效果,好的视电阻率定义可以提高反演分辨率。传统的Cagniar视电阻率(1953)只是利用了波阻抗的模值,而Basokur 1994年提出的视电阻率利用波阻抗的实部和虚部。本文做了4个不同模型的Basokur视电阻率响应及反演,结果显示新的视电阻率对薄层有很好的反应,对常规模型也有不错的表现。

| Abstract: | Different definitions of apparent resistivity can educe dissimilar inversion results in electrical exploration.A finer definition can improve the inversion accuracy.The traditional Cagniar apparent resistivity which was defined by Cagniar in 1953 only make use of modulus values of wave impedance,but Basokur defined the apparent resistivity in 1994 including real part and imaginary parts of wave impedance.In this paper the forward and inversion based on the Basokur definition for four different models are done.The results show that new resistivity can imagine different models with thin layers,and also with common layers in model. |
