Abstract
It is generally believed that the monopole acoustic logging cannot be used to invert the S-wave velocity in a soft formation. However, the theoretically synthesized pressure waveform of monopole acoustic logging changes obviously with S-wave velocity, indicating a correlation between the two. This paper uses one-dimensional convolution neural network to invert the S-wave velocity. In the absence of dipole S-wave logging data, S-wave velocity is inverted with less than 2% error through the full waveform of monopole acoustic logging.
