The explosive effect of vibroseis is directly related to the quality of acquired data by vibroseis.Usually combined excitation of means is used to ensure energy.This method will theoretically influence the effect of seismic data.The reflection time difference between the combinations lead to out-phase stacking,which affects the geological imaging precision.Through theoretical calculation,modeling and real seismic data analysis,the authors found the influence regularity of time-space domain.With less number of vibroseis area array,combined with high folds and geophone array,we can effectively reduce the influence.This method also improves the efficiency and reduce cost,is easier to implement in the complex surface area,and is more suitable for high precision acquisition.
