[0054] Figure 2 A flow chart of a method for generating a seismic trace gather index according to an embodiment of the present application is provided. The execution subject of this embodiment may be Figure 1 The electronic device shown in FIG. is not particularly limited in this embodiment. Figure 2 As shown, the method includes:

[0055] S201: Acquire a seismic volume gather file, wherein the seismic volume gather file stores a plurality of gathers.

[0056] Among them, the file format of the seismic volume gather file can be SEGY, SEG2, etc.

[0057] In an example of the present application, the data format in the seismic volume gather file includes file text header information, file binary header information, multiple gathers, and the like.

[0058] The file header information includes 40 lines of text information, which gives an overall description of the seismic data in the file, including the collector, operation team number, user, time, sampling interval, number of coverage, etc.

[0059] The file binary header information is 400 bytes, which is a 2- or 4-byte binary complement integer. The file binary header information includes binary values ​​that affect the entire file, including the data set type, data channel number, sampling interval, sampling point number, and sampling format code (each point requires multiple bytes of storage space).

[0060] Among them, the track set includes multiple tracks, each of which includes a track header and a track body. The track header is 240 bytes, including the attributes of each track, which is a 2-byte or 4-byte binary complement integer. For different tracks, the track header information may be different. The information contained in the track header can be the horizontal and vertical coordinates of the track, the field file number, the shot number, the track number, the offset, the elevation, the CMP (Common Midpoint) track set number, the three-dimensional main survey line number (Inline) of the CMP track set, and the three-dimensional contact line number (Crossline) of the CMP track set. Taking the CMP track set as an example, the tracks with the same CMP track set number or Inline number need to be grouped into one track set.

[0061] Figure 3 A schematic diagram of the data format in a seismic volume gather file provided for one embodiment of the present application.

[0062] S202: Divide the seismic volume gather file into a plurality of file blocks according to a preset number of blocks.

[0063] It should be noted that when dividing the blocks, the "road" cannot be split in the middle, so it will be split according to the integer length of the road.

[0064] Specifically, a preset number of blocks is obtained; metadata information of a seismic volume gather file is obtained; block data is calculated according to the preset number of blocks and the metadata information of the seismic volume gather file; and the seismic volume gather file is divided into a plurality of file blocks according to the block data.

[0065] The metadata information of the seismic volume gather file includes: file length, number of sampling points of a single channel, point storage byte length, trace header length, file text header information length and file binary header information length, etc.

[0066] The calculation formula for the single-track length of the seismic volume gather file is: single-track length = point storage byte length * number of track sampling points + track header length.

[0067] The calculation formula of the file header length of the seismic volume gather file is: file header length = file text header information length + file binary header information length.

[0068] The calculation formula for the total number of traces in a seismic volume gather file is: total number of traces in a file = (file length - file header length) / single trace length.

[0069] Among them, if the preset number of blocks is n, then the file size of each block of the first n-1 blocks of files = total number of file tracks / preset number of blocks*single track length; the file size of the nth block of files = total number of file tracks%preset number of blocks*single track length.

[0070] Among them, the starting position of the first file block = the length of the file header; the ending position of the first file block = the length of the file header + the size of each file block of the first n-1 files; if 2≤m≤n, and m is an integer, then the starting position of the mth file block = the ending position of the m-1th file block + 1; if 2≤x≤n-1, and x is an integer, then the ending position of the xth file block = the starting position of the xth file block + the size of each file block of the first n-1 files; the ending position of the nth file block = file length-1.

[0071] For example, if the file header length = a, the size of each file block of the first n-1 blocks of files = b, the file length = c, and n = 3, then the starting position of the first block of files = a; the ending position of the first block of files = a+b; the starting position of the second block of files = a+b+1; the ending position of the second block of files = a+2b+1; and the ending position of the third block of files = c-1.

[0072] S203: For each file block, calculate the gather information of all gathers in the file block, and after the calculation is completed, generate a calculation completion record corresponding to the file block, wherein the gather information includes the gather number, the gather start position and the gather end position.

[0073] Each of the plurality of track gathers includes a plurality of tracks.

[0074] It should be noted that the starting position of the gather is the starting position of the gather in the seismic volume gather file; the ending position of the gather is the ending position of the gather in the seismic volume gather file.

[0075] Specifically, S203 specifically includes S2031~S2035:

[0076] S2031: For each file block, obtain the first track set number of the first track in the file block.

[0077] Specifically, the data of the file block is parsed to obtain the attribute information of the first track of the file block; and the track set number in the attribute information is extracted.

[0078] S2032: Determine the starting position of the first track of the file block as the original track gather position and the current position.

[0079] S2033: Obtain the preset number of gather attempts.

[0080] S2034: Obtain the single track length of any track in the file block.

[0081] It should be noted that the length of each single trace in the seismic volume gather file is the same.

[0082] S2035: Calculate the gather information of all gathers in the file block according to the number of gather attempts, the length of a single track, the original gather position and the current position.

[0083] Specifically, S2035 includes Sa~Se:

[0084] Sa: Calculate the target position based on the single-track length, current position, and number of track attempts.

[0085] Among them, the target position = current position + single track length * number of track set attempts.

[0086] Sb: If it is determined that the target position belongs to a file block, the second track set number of the track to which the target position belongs is obtained.

[0087] Sc: Determine whether the first track set number is the same as the second track set number.

[0088] Sd: If it is determined that the first track set number and the second track set number are the same, then determine whether the target position is at the end of the file block; if it is determined that the target position is at the end of the file block, obtain and save the maximum track set and the minimum track set of the file block, and end the calculation process of the file block.

[0089] The position of the end of the file block is expressed as the file block length-single track length-1.

[0090] Specifically, if it is determined that the target position is at the end of the file block, the maximum track gather and the minimum track gather in the preset data table are obtained, and the maximum track gather and the minimum track gather are persistently stored.

[0091] Among them, the persistent storage method can be ES (Elasticsearch, a distributed full-text search engine) storage.

[0092] Se: If it is determined that the first track gather number and the second track gather number are not the same, calculate the difference between the target position and the current position; if it is determined that the difference is equal to the single track length, save the original track gather position and the target position as the track gather start position and the track gather end position of the new track gather; calculate and update the maximum track gather and the minimum track gather of the file block; update the number of track gather attempts to the number of tracks between the target position and the original track gather position; update the original track gather position to the target position; update the first track gather number to the second track gather number; update the current position to the target position; repeat the steps of "calculating the target position based on the single track length, the current position and the number of track gather attempts" until the target position is at the end of the file block.

[0093] S204: Obtain the gather numbers of all gathers in the multiple file blocks.

[0094] S205: If it is determined that there are repeated gather numbers, all gather start positions and gather end positions corresponding to the gather numbers are obtained.

[0095] Among them, the existence of repeated track set numbers means that one track set is divided into two file blocks.

[0096] Figure 4 An example diagram of a gather divided according to an embodiment of the present application.

[0097] S206: Arrange all the track gather start positions and track gather end positions in ascending order, determine the smallest track gather start position as the track gather start position of the track gather corresponding to the track gather number, and determine the largest track gather end position as the track gather end position of the track gather corresponding to the track gather number.

[0098] Exemplarily, suppose the starting positions of the track gathers corresponding to the track gather numbers are q and w respectively; the ending positions of the track gathers corresponding to the track gather numbers are w and e respectively; and they are sorted in order of size as q, w, w, e, then the starting position of the track gather corresponding to the track gather number is q, and the ending position of the track gather corresponding to the track gather number is e.

[0099] S207: Calculate the calculation status of the seismic volume gather file according to all calculation completion records.

[0100] The calculation formula for calculating the calculation status of the seismic volume gather file is: the calculation status of the seismic volume gather file = the number of all calculation completed records / the preset number of blocks * 100%.

[0101] S208: Generate a gather index according to the gather information of all gathers in the multiple file blocks, and save the calculation status of the seismic volume gather file.

[0102] The gather index includes the gather start position, gather end position and key attribute values ​​of each gather.

[0103] Specifically, the gather start position, the gather end position and the key attribute value in the gather information are extracted to generate a gather index; the gather index is persistently stored, and the calculation state of the seismic volume gather file is persistently stored.

[0104] Among them, the persistent storage method can be ES storage.

[0105] As can be seen from the above description, the present application divides the seismic gather file into multiple file blocks; for each file block, calculates the gather information of all gathers in the file block; obtains the gather numbers of all gathers in multiple file blocks; if it is determined that there are repeated gather numbers, obtains all the gather start positions and gather end positions corresponding to the gather numbers; determines the smallest gather start position as the gather start position of the gather corresponding to the gather number, and determines the largest gather end position as the gather end position of the gather corresponding to the gather number; generates gather indexes according to the gather information of all gathers in multiple file blocks. It can speed up the generation of seismic data gather indexes at various stages and consume data quickly.

[0106] In one embodiment of the present application, based on the above embodiment, after the step Se of "if it is determined that the first track gather number and the second track gather number are not the same, then the difference between the target position and the current position is calculated", a process of updating the number of track gather attempts is also included, which is described in detail as follows:

[0107] Se-1: If the difference is not determined to be a single-track length, the preset algorithm is used to update the number of track gather attempts.

[0108] Among them, the preset algorithm can be a binary search method.

[0109] Se-2: Repeat the step of "calculating the target position according to the single-track length, the current position and the number of track gather attempts" until the target position is at the end of the file block.

[0110] From the above description, it can be seen that in the present application, a preset algorithm is used to update the number of track gather attempts, so that the track gather start position and the track gather end position of the new track gather can be quickly found.

[0111] In one embodiment of the present application, based on the above embodiment, after the step Sd of "determining whether the target position is at the end of the file block", a process of quickly skipping the file block is also included, which is described in detail as follows:

[0112] Sd-1: If it is determined that the target position is not at the end of the file block, the current position is updated to the target position.

[0113] Sd-2: Repeat the steps of "calculating the target position based on the single-track length, current position and number of track gather attempts" until the target position is at the end of the file block.

[0114] From the above description, it can be seen that in this application, if the target position is determined not to be at the end of the file block, the current position is updated to the target position. Rapidly skipping the file block improves the generation speed of the seismic data gather index at each stage.

[0115] In one embodiment of the present application, based on the above embodiment, after step Sb, a processing process for excessive number of gather attempts is further included, which is described in detail as follows:

[0116] Sf: If it is determined that the target position does not belong to the file block, the target position is updated to the end of the file block.

[0117] The position of the end of the file block is expressed as the file block length-single track length-1.

[0118] Sg: Get the second track set number of the track to which the target position belongs.

The execution subject of this embodiment may be Figure 1 The electronic device shown in FIG. is not particularly limited in this embodiment. Figure 5 As shown, the method includes:
