Abstract：The flip-flop sweep, the slip sweep, and the distance separated simultaneous sweep (DS3) are the three most commonly used ways of high-productivity vibroseis technology.Because of their difference in technical characteristics, operation organization, and equipment resource demand, usually only one of them is used independently in the past operation, which limits their application areas and affects the production.In order to solve this problem, a new approach, dynamic sweep, is developed.This approach not only considers the time domain change as in the past, but also adopts the concept of the space domain, and combines them by establishing the time-space relations rules.Thus the flip-flop sweep, the slip sweep, and the DS3 are integrated together.According to the pre-set time-space rule, recording systems can freely group vibrators and switch the sweep modes.The proposed vibroseis dynamic sweep can adapt to more terrain conditions and achieve further higher production.
