Generally speaking, the terms "comprises" and "includes" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list.

[0027] For ease of understanding, the technical solution of the present application is introduced below in conjunction with the accompanying drawings and embodiments.
[0028] Figure 1 FIG. 1 is an exemplary flow chart of a method for checking consistency of seismic data according to some embodiments of the present application. Figure 1 As shown, the consistency verification method of seismic data includes the following steps:
[0029] Step S110, extracting characteristic data from the seismic data file to be verified; wherein the characteristic data is part of the content in the seismic data file to be verified.
[0030] The seismic data file to be verified is a seismic data file that needs to be verified. For example, the seismic data file to be verified may be a source seismic data file to be archived or shared. In order to avoid repeated uploading, it needs to be verified.
[0031] The seismic data file to be verified includes file header data, trace header data and sample point value data.
[0032] The file header data and trace header data store the basic information, coordinates and other key feature information of the seismic data file, and all need to be compared as valid data. Therefore, in some embodiments, the file header data and trace header data are extracted from the seismic data file to be verified as the first sub-feature data.
[0033] As an example, in a SEG-Y data format with a size of more than 1TB (such as Figure 3 When the consistency check is performed on the seismic data file to be checked (as shown in Figure 4 As shown, a 3200-byte text file header and a 400-byte binary file header can be read; the number of extended file headers N is obtained from bytes 3505 to 3506, and then N*3200 bytes are read backward; 3200+400+N*3200 bytes of content are used as complete file header data.
[0034] Due to the particularity of the use scenario of seismic data, the sample value data changes as a whole in units of seismic traces. By extracting part of the sample value data in units of seismic traces as key feature information for comparison, the change of the sample value data can be detected. Therefore, in some embodiments, according to the file header data and the trace header data, part of the sample value data is extracted in units of traces from the seismic data file to be verified as the second sub-feature data.
[0035] In the specific implementation process, part of the sample value data can be extracted from the seismic data file to be verified in units of channels as the second sub-feature data in a variety of ways. For example, the sample value data of the first sample point, the middle sample point and the last sample point can be extracted from the sample value data of each seismic channel as the second sub-feature data. For another example, the sample value data can be extracted from the preset sampling points (for example, 100) at intervals of each seismic channel as the second sub-feature data.
[0036] For a specific embodiment of extracting part of the sample value data in units of channels as the second sub-feature data, see Figure 2 The relevant content in will not be repeated here.
[0037] Finally, the feature data is obtained according to the first sub-feature data and the second sub-feature data. For example, the first sub-feature data and the second sub-feature data may be concatenated according to a preset format to obtain the feature data.
[0038] Step S120, based on the characteristic data, using a preset verification algorithm, calculate and obtain verification information of the seismic data file to be verified.
[0039] In the specific implementation process, a variety of preset verification algorithms can be used to process the characteristic data obtained in step S110 to calculate the verification information of the seismic data file to be verified, including but not limited to: MD5, SHA1, SHA256 and other verification algorithms.
[0040] During the specific implementation process, while extracting characteristic data from the seismic data file to be verified, the extracted characteristic data can be calculated through a preset verification algorithm (for example, MD5). When the characteristic data extraction is completed, unique verification information (for example, a hash value of 16 characters) of the seismic data file to be verified is generated.
[0041] Step S130, determining the consistency between the seismic data file to be verified and the comparison seismic data file based on the verification information of the seismic data file to be verified and the verification information of the comparison seismic data file that has been obtained.
[0042] The verification information of the comparison seismic data file has been obtained and stored according to the method described in step S110 and step S120. For example, the comparison seismic data file is an archived seismic data file. In the process of archiving it, the verification information of the comparison seismic data file is calculated according to the method provided in the present application, and the calculated verification information and the comparison seismic data file are stored in the database together.
[0043] During the specific implementation process, the verification information of the seismic data file to be verified can be compared with the verification information of the comparison seismic data file. If the two are the same, it can be determined that the seismic data file to be verified and the comparison seismic data file are the same seismic data file, and there is no need to archive or share them. If the two are different, it can be determined that the seismic data file to be verified and the comparison seismic data file are not the same seismic data file, and there is a need to archive or share them.
[0044] In the embodiment provided by the present application, according to the storage structure and data usage scenario of the seismic data file, part of the content is extracted from the seismic data file to be verified as feature data, and then according to the feature data, the verification information of the seismic data file to be verified is calculated using a preset verification algorithm, so that the amount of data involved in the verification calculation can be effectively reduced, and the efficiency of seismic data verification can be greatly improved; according to the verification information of the seismic data file to be verified and the verification information of the comparison seismic data file obtained, the consistency between the seismic data file to be verified and the comparison seismic data file is determined, so that the consistency verification can be quickly performed with the existing seismic data during digital archiving, thereby avoiding repeated data upload, saving storage space, and ensuring data security. Through actual data testing, the verification information of multiple 1TB seismic data is calculated according to the method provided by the present application, and the time consumption is reduced from 75 minutes required in the relevant technology to less than 2 minutes, and the accuracy of the test data is 100% through application.
[0045] Figure 2 It is an exemplary flow chart of extracting partial sample value data from a seismic data file to be verified according to some embodiments of the present application.
[0046] Step S210: Obtain the storage byte number of the sample value data according to the file header data.
[0047] In the specific implementation process, the number of bytes of the sample value data can be obtained from the preset position of the file header data according to the format of the seismic data file to be verified (for example, SEG-Y, SEG-D or other seismic data formats). Figure 4 The data format code is obtained from bytes 3225 to 3226 of the file header data shown, and the number of storage bytes M of each sample value data is known according to the data format code.
[0048] After obtaining the storage byte number of the sample value data, the following steps can be performed for each seismic trace recorded in the seismic data file to be verified:
[0049] Step S220, obtaining the number of sample value data collected from the seismic trace according to the trace header data corresponding to the seismic trace.
[0050] In the specific implementation process, the number of sample value data collected by the seismic trace can be obtained from the preset position of the trace header data according to the format of the seismic data file to be verified (for example, SEG-Y, SEG-D or other seismic data formats).
[0051] As an example only, for the example in step S210, Figure 5As shown, 240 bytes of trace header data can be read continuously, wherein the number of sampling points L of the seismic trace is obtained from the 115th to 116th bytes.
[0052] Step S230: extracting part of the sample value data from the sample value data as key feature sample value data according to the number of the sample value data and the number of bytes for storing the sample value data.
[0053] In a specific implementation process, the position of the partial sample value data to be extracted in the sample value data can be determined according to the number of sample value data and the number of bytes stored in the sample value data, and then the key feature sample value data can be extracted according to the position.
[0054] As an example only, for the example in step S220, the 1st, L / 2nd, and Lth sample value data of the seismic trace, a total of 3*M bytes of data, can be read as key feature sample value data.
[0055] Step S240: taking the key characteristic sample value data corresponding to all seismic traces as the second sub-characteristic data.
[0056] In a specific implementation process, the key characteristic sample value data corresponding to all the seismic traces obtained above can be combined into the second sub-characteristic data in a preset manner (for example, by splicing in the order of data extraction).
[0057] In the embodiment provided by the present application, the number of storage bytes of the sample value data is obtained according to the file header data; for each seismic track recorded in the seismic data file to be verified, the following steps are performed: according to the track header data corresponding to the seismic track, the number of sample value data collected from the seismic track is obtained; according to the number of sample value data and the number of storage bytes of the sample value data, part of the sample value data is extracted from the sample value data as key feature sample value data; thereby, according to the key feature sample value data corresponding to all seismic tracks, a second sub-feature data with a small data volume and which can accurately reflect the seismic track data information unique to the seismic data file to be verified is obtained, and then according to the second sub-feature data, the verification information of the seismic data file to be verified can be efficiently and accurately calculated.

[0059] like Figure 6 As shown, the consistency verification device for seismic data includes: a first acquisition module 610 , a second acquisition module 620 and a determination module 630 .
[0060] The first acquisition module 610 is used to extract characteristic data from the seismic data file to be verified; wherein the characteristic data is part of the content in the seismic data file to be verified.
[0061] The second acquisition module 620 is used to calculate and obtain the verification information of the seismic data file to be verified according to the characteristic data using a preset verification algorithm.
[0062] The determination module 630 is used to determine the consistency between the seismic data file to be verified and the comparison seismic data file according to the verification information of the seismic data file to be verified and the verification information of the obtained comparison seismic data file.
