Abstract：Shooting by explosive is main exploded mode in land seismic exploration.The exploded factor is obviously vital to seismic exploration (especially to high-resolution seismology).Although there were many literatures about exploded theory and parameter selection,the analysis made in many cases is in a condition of certain explosive type and quantity,so the results are not generality.The aim studying exploded condition is to obtain ideal exploded wavelet,but there are a few methods that made observation and analysis directly to exploded wavelet.The paper introduced method for varied formed explosive with different quantity which is both exploded and observed in high speed layer,qualitatively and quantitatively analyzed acquired seismic wavelet formed in elastic zone,mainly including wavelet waveform character,spectrum,relation between seismic wavelet energy and quantity of explosive as well as rule of attenuation in a high speed layer etc,and it came to a series of meaningful conclusion.
