一种确定坏道数据的方法及装置
Abstract:
本申请提供一种确定坏道数据的方法及装置，其中，所述方法包括：对采集的地震道数据进行动校正处理，得到动校正后的地震道数据；从所述动校正后的地震道数据中获取预设时窗内的第一地震道数据；将所述动校正后的地震道数据进行时差校正，得到时差校正后的地震道数据；从所述时差校正后的地震道数据中获取所述预设时窗内的第二地震道数据；确定所述第一地震道数据和所述第二地震道数据的相关性；根据确定的所述相关性，确定所述采集的地震道数据是否为坏道数据。本申请实施例提供的一种确定坏道数据的方法及装置，能够避免人工筛选带来的误差并且保证在后续数据处理过程中不再出现坏道数据。
Abstract(English):

The invention provides a method and apparatus for determining bad trace data. The method for determining bad trace data comprises: performing dynamic correction on the collected seismic trace data, and obtaining the seismic trace data after dynamic correction; acquiring first seismic trace data in a preset time window from the seismic trace data after dynamic correction; performing time difference correction on the seismic trace data after dynamic correction, and obtaining the seismic trace data after time difference correction; acquiring second seismic trace data in the preset time window from the seismic trace data after time difference correction; determining the correlation between the first seismic trace data and the second seismic trace data; and according to the correlation, determining whether the collected seismic trace data is bad trace data. The method and apparatus for determining bad trace data can avoid errors caused by artificial screening and guarantee no occurrence of bad trace data during the subsequent data processing process.
