Abstract:

Noise analysis is always the important basic method to improve the signal-to-noise ratio of seismic data. Seismic vibrator system emits instantaneous low energy to the underground, so its record is easier to be disturbed by the pulse noise from interior of vibrator system and background. The cross-correlation detection method, which is used to pick signals, can not suppress this kind of noise, and it even widen the noise level seriously. To study pulse noise interference, the authors analyze the impact and characteristics of the record by the single pulse and multi-point pulse noise in theory and simulation. The results showed that the interference is mainly depended on the strength of the impulse noise, the position time and proportion of pulse noise. When 2.5% pulse noise is mixed into vibrator non-correlated data with average intensity is 100, the vibrator signal would be submerged in correlated data.

Key words: vibrator, signal-to-noise ratio (SNR), correlated detection, pulse noise
