| 摘要 |
An illustrative embodiment of the present invention includes methods for Seismic Data Processing which may be used to enhance the signal/noise ratio of seismic signals taken by use of the Common Depth Point or Hundred Percent Coverage survey techniques. The methods preserve time alignment and amplitude of the signals while effectively removing the noise therefrom. Small portions of the record centered at a selected time on a selected trace are processed to extract the coherent signal component from the reference trace as determined by comparison with other spacewise adjacent traces. Output records comprising the enhanced signal data and the noise data are produced. |
