摘要
In this paper, “non-linear high order polynomial fit method”, a new technology is also introduced to transform resistivity profile into velocity profile under the control of a little micro-well logging. Kriging interpolation method is used for calculating the planar velocity distribution of low velocity zone from five profiles TEM data. The results indicated that this method can be used for studying subtly the variety characteristic of electric parameters of subsurface layer within 10 to 300 meters depth range.
