Seismic vibratory acquisition method and apparatus |
| 摘要 |
A method and related apparatus are described for generating acoustic signals for use in a vibratory seismic survey, including at least two different sweep signals for the control of at least two different types of vibrators; and matching the phases of the different sweep signals at a transition frequency from one sweep signal to another. |

1. A method of generating acoustic signals for use in a vibratory seismic survey, comprising:
generating at least two different sweep signals for the control of at least two different vibrators; using the at least two different sweep signals in a single sweep having a duration longer than the duration of each of the at least two different sweep signals and proportional to the number of vibrators; and matching the phases of the different sweep signals at a transition frequency from one sweep signal to another. |
