Abstract
Vibroseis seismic acquisition technology is a method of acquiring seismic data utilizing correlation technology. Specifically, the seismic single shot record is obtained through correlation between the reference signal and the mother record. Specifically, the seismic single shot record is obtained through correlation between the reference signal and the mother record. Specifically, the seismic single shot record is obtained through correlation between the reference signal and the mother record. In line with pertinent technical regulations, greater correlation between the two signals equates to superior correlation outcomes. The reference signal is transmitted to the surface via the vibration of the vibrating plate. This is achieved using the vibroseis machine. However, due to the coupling relationship between the vibrating plate and the surface, the vibration signal output by the former is not equivalent to the vibration signal received by the latter. Consequently, the correlation between the reference signal and parent record fails to procure the best correlation result. In this paper, a technique is presented for establishing a correlation between the surface vibration signals captured by the geophone in proximity to the vibroseis and the reference record. This approach improves the quality of the correlated single shot, and holds significant potential for broad dissemination.
