| Abstract: | Smooth transient signals are regarded as mathematical models of waves in full wavetrain acoustic logging.Studies waveforms of their continuous wavelet transform, presents a new method to detect their start points, by which wavefronts of the sliding P-waves, the sliding S-waves and the stoneley waves in full wavetrain acoustic logging can be estimated precisely. |

| Keywords: | full wavetrain acoustic logging sliding P wave sliding S wave stoneley wave wavelet transform |
