Abstract：Focusing on the issues of application of vibroseis technique and selection of parameters, the paper discussed emphatically the issue of vertical stack, driven amplitude, sweeping slope and shooting energy etc and presented some new knowledge and suggestions. The vertical stack is out of action on the time-invariable noises;increasing the folds is more benefit to depress the noises rather than increasing the number of vibration; increasing the driven amplitude to a certain degree may not increase down-going energy of sweeping signal but increase harmonic contents on the contrary; the sweeping slope can depress low frequency and reduce the Gibbs' phenomenon; the vibration energy power is in proportion to sweeping length and the sweeping energy power of unit frequency is in inverse proportion to sweeping frequency width. During the use of vibroseis, the people should overcome the shortcoming of selecting the parameters by experiences; on the contrary, it should select parameters by more scientific analysis and quantitative computation.
