According to the significant difference in the frequency domain of different resolution logging data, the resolution conversion between the same and different physical logging data with different resolutions is realized by using the potential theory and the fractal geometric projection theorem. Which use wavelet transform theory to determine the size and shape of the window in the window Fourier transform. The results show that this method has good practicability and wide universality.
