[0037] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings and examples, so that the process of how the present invention uses technical means to solve technical problems and achieve corresponding technical effects can be fully understood and implemented accordingly. The embodiments of the present invention and the various features therein can be combined with each other without conflict, and the resulting technical solutions are all within the protection scope of the present invention.

[0038] Example 1

[0039] like Figure 1 As shown, an embodiment of the present invention provides a seismic trace data replacement method, including the following steps S101 to S105:

[0040] Step S101: Acquire target earthquake data and source earthquake data.

[0041] For example, target earthquake data and source earthquake data are acquired through earthquake acquisition instruments.

[0042] Step S102: Obtain the trace head value of the target seismic data from the seismic traces of the target seismic data according to the trace collection type of the target seismic data.

[0043] For example, the target seismic data is loaded into the corresponding processing node at the smallest granularity of the trace set. The processing node then reads the seismic traces in the trace set in a loop and reads the value of the corresponding trace head from the seismic trace according to the trace set type.

[0044] Step S103: Obtain the trace head value of the source seismic data from the seismic traces of the source seismic data according to the trace collection type of the source seismic data.

[0045] For example, source seismic data is loaded into the corresponding processing node at the smallest granularity of trace sets. The processing node then reads the seismic traces in the trace sets in a loop and reads the corresponding trace head value from the seismic traces according to the trace set type.

[0046] Step S104: Determine whether the trace head value of the target seismic data is equal to the trace head value of the source seismic data.

[0047] For example, based on the order of the target fields, it can be determined whether the trace header field value of the target seismic data is equal to that of the source seismic data. For instance, if the first trace header field value of the target seismic data is equal to the first trace header field value of the source seismic data, and the second trace header field value of the target seismic data is greater than the second trace header field value of the source seismic data, then the trace header value of the target seismic data is greater than the trace header value of the source seismic data. Figure 4As shown, earthquake data A is the target earthquake data, excluding trace data; earthquake data B is the source earthquake data; and earthquake data C is the replaced target earthquake data, including the trace data below. During the comparison, FFID, Channel_Num, Inline, and Crossline are compared in sequence. For example, when comparing the trace header values ​​in the second row, FFID is 501031694 for both, but the Channel_Num of the target earthquake data is 285, which is greater than the Channel_Num of the source earthquake data, which is 284. Therefore, the trace header value of the target earthquake data is greater than that of the source earthquake data.

[0048] Step S105: If the trace head value of the target seismic data is equal to the trace head value of the source seismic data, then replace the corresponding trace data in the target seismic data with the corresponding trace data in the source seismic data.

[0049] If the trace header value of the target seismic data is equal to the trace header value of the source seismic data, then the corresponding trace data in the target seismic data is replaced with the corresponding trace data in the source seismic data. If the trace data in the target seismic data is empty, then that trace data is inserted. The next trace of both the target seismic data and the source seismic data is read for judgment and replacement.

[0050] For example, if the trace head value of the target seismic data is less than the trace head value of the source seismic data, the corresponding trace data in the target seismic data is retained, and the corresponding trace data in the current target seismic data is written into the final result. The next trace data of the target seismic data is then read, judged, and replaced. If the corresponding trace data in the target seismic data is empty, the corresponding trace data in the target seismic data is replaced with preset trace data, such as trace data with all values ​​of 0.

[0051] For example, if the trace head of the target seismic data is greater than that of the source target seismic data, then the trace data of the target seismic data is retained; if the trace data in the target seismic data is empty, then an empty trace with all values ​​of 0 is inserted. Figure 4 As shown, the trace data with FFID 501031694 and Channel_Num 285 are all 0. Read the next trace of the target seismic data, make judgments and replace it. If all traces of the target seismic data have been processed, the processing ends.

[0052] For example, if the lead value of the target seismic data is greater than the lead value of the source seismic data, then the next lead of the source seismic data is read.

[0053] If the trace head of the target seismic data is smaller than that of the source seismic data, then the next trace of the source seismic data is read. If all traces of the source seismic data have been processed, then all remaining traces in the target seismic data are retained without replacement. If the trace data in the target seismic data is empty, then empty data with all remaining trace counts set to 0 is inserted, and the processing ends.

[0058] The second acquisition module is used to obtain the trace header value of the source seismic data from the seismic traces of the source seismic data according to the trace collection type of the source seismic data.

[0059] Decision module: Used to determine whether the trace head value of the target seismic data is equal to the trace head value of the source seismic data;

[0060] Replacement module: If the trace header value of the target seismic data is equal to the trace header value of the source seismic data, then the corresponding trace data in the target seismic data will be replaced with the corresponding trace data in the source seismic data.

[0061] Optionally, the judgment module further includes a field judgment unit: used to judge whether the trace header field value of the target seismic data is equal to the trace header field value of the source seismic data according to the target field order.
