GHOST-SUPPRESSION OPTIMIZED SEISMIC SOURCE AND METHOD |
| 摘要 |
A marine seismic source includes source elements configured to emit waves having different frequencies while the source elements are towed at different predetermined depths, respectively. The predetermined depths are calculated such that water-surface reflections of the waves generated by a source element among the source elements interfere constructively with the waves generated by the source element and propagating toward an explored structure under the seafloor. The waves combine to yield a spike-like signature of the source. |

1. A marine seismic source, comprising:
a plurality of source elements configured to emit waves having different frequencies while the source elements are towed at different predetermined depths, respectively,
the predetermined depths being calculated such that down-going waves generated by a source element among the source elements at one of the predetermined depths interfere constructively with water-surface reflections due to up-going waves generated by the source element, andthe waves combining to yield a spike-like signature of the marine seismic source. |
