Description

Technical Field

[0001] The embodiments of this specification relate to the field of exploration data processing technology, and more particularly to a data splicing method and device. Background Art

[0002] With the development of seismic exploration technology, seismic data acquisition methods have gradually become mature and accurate, so that more abundant underground geological information and more accurate seismic imaging can be obtained, which is convenient for subsequent business use. However, with the increase of density and azimuth, the cost of seismic exploration acquisition will also increase sharply. Therefore, in order to reduce the exploration cost, it is necessary to conduct in-depth information mining on conventional acquisition data, and splice and fuse the newly acquired wide-azimuth high-density data and conventional seismic data during the processing process to carry out overall geological research. However, due to the differences in acquisition methods and observation systems, various problems will arise in the splicing process; for example, improper processing will cause loss of azimuth information, uneven coverage will cause offset imaging arcing, and excessive interpolation will cause signal distortion. In the prior art, one way to splice seismic data collected in wide and narrow azimuths is to divide the data into equal distances according to the traditional processing method of seismic data acquisition, and carry out energy adjustment based on the number of coverage within the offset to solve the offset arcing problem. However, this method will lose the azimuth information of the original data, and it is very easy to cause unreasonable local position compensation. Another method is to perform five-dimensional regular interpolation on the narrow azimuth data in the blast area according to the parameters of the wide azimuth data to make it as consistent as possible with the wide azimuth data. This method requires the assistance of five-dimensional regularization software, and the amount of calculation is huge and the cycle is very long. At the same time, the interpolation data is calculated according to the surrounding data according to the mathematical algorithm, and the geological information it contains is at risk of distortion, especially when the interpolation is too large and the interpolation data exceeds the original data, the risk will increase sharply. Therefore, an effective solution is urgently needed to solve the above problems. Summary of the invention

[0064] In this specification, a data splicing method is provided. This specification also relates to a data splicing device, a computing device, a computer-readable storage medium and a computer program product, which are described in detail one by one in the following embodiments.

[0065] See also Figure 1 , Figure 1 A flow chart of a data splicing method provided according to an embodiment of the present specification is shown, which specifically includes the following steps.

[0066] Step S102, collecting wide-azimuth seismic data and narrow-azimuth seismic data, and determining wide-azimuth line spacing information corresponding to the wide-azimuth seismic data and narrow-azimuth line spacing information corresponding to the narrow-azimuth seismic data.

[0067] The data splicing method provided in this embodiment can be applied to any geographical exploration scenario, such as oil exploration scenario or geological exploration scenario, etc. By splicing adjacent wide-azimuth seismic data and narrow-azimuth seismic data in the OVT (Offset Vector Tile domain), the offset imaging arcing problem caused by the difference in the number of adjacent data coverage can be effectively eliminated, while better retaining the azimuth information contained in the original data, laying a data foundation for subsequent comprehensive geological research, and providing high-quality seismic data for downstream business use.

[0068] Specifically, wide azimuth seismic data and narrow azimuth seismic data specifically refer to seismic data obtained after seismic data collection for the target area; wherein, the collection method of wide azimuth seismic data and narrow azimuth seismic data is not limited in this embodiment. Accordingly, wide azimuth line spacing information specifically refers to the shot line spacing information and detection line spacing information set when collecting wide azimuth seismic data. Accordingly, narrow azimuth line spacing information specifically refers to the shot line spacing information and detection line spacing information set when collecting narrow azimuth seismic data.

[0069] Based on this, in order to effectively eliminate the problem of arcing in offset imaging caused by the difference in the number of adjacent data coverages, wide-azimuth seismic data and narrow-azimuth seismic data can be collected first, and then the wide-azimuth line spacing information corresponding to the wide-azimuth seismic data and the narrow-azimuth line spacing information corresponding to the narrow-azimuth seismic data can be determined; on this basis, in order to ensure that the wide-azimuth seismic data and the narrow-azimuth seismic data can be spliced ​​more reasonably, multiple wide-azimuth cross-gathers can be constructed based on the wide-azimuth seismic data, and multiple narrow-azimuth cross-gathers can be constructed based on the narrow-azimuth seismic data; thereafter, for the wide-azimuth seismic data, each wide-azimuth cross-gather can be constructed according to the wide-azimuth line spacing information. Facet division, construct wide azimuth facet gathers according to the facet division results; on this basis, in order to be able to perform effective splicing and improve efficiency without relying on third-party processing software, the narrow azimuth line distance information can be mapped to the target narrow azimuth line distance information using the wide azimuth line distance information, and then each narrow azimuth cross-gather is faceted according to the target narrow azimuth line distance information, and narrow azimuth facet gathers are constructed according to the facet division results; after obtaining the wide azimuth facet gathers and narrow azimuth facet gathers that have an aligned relationship in the attribute dimension, facet splicing can be performed on the wide azimuth facet gathers and the narrow azimuth facet gathers, so that the target seismic data can be generated according to the splicing results.

[0070] Furthermore, when determining the line spacing information corresponding to the wide azimuth seismic data and the narrow azimuth seismic data, the structural information is actually obtained by combining the line spacing information set when collecting seismic data. In this embodiment, the specific implementation method is as follows:

[0071] Determine the wide azimuth shot line spacing information and the wide azimuth detection line spacing information corresponding to the wide azimuth seismic data as the wide azimuth line spacing information; determine the narrow azimuth shot line spacing information and the narrow azimuth detection line spacing information corresponding to the narrow azimuth seismic data as the narrow azimuth line spacing information.

[0072] Based on this, the collection of wide-azimuth seismic data and narrow-azimuth seismic data requires the setting of the shot line spacing and the detection line spacing. Therefore, the wide-azimuth shot line spacing information and the wide-azimuth detection line spacing information corresponding to the wide-azimuth seismic data can be determined as the wide-azimuth line spacing information; and the narrow-azimuth shot line spacing information and the narrow-azimuth detection line spacing information corresponding to the narrow-azimuth seismic data can be determined as the narrow-azimuth line spacing information for subsequent use.

[0073] For example, when collecting seismic data for the target area, the shot line distance a of the wide azimuth seismic data is set to 150, and the detection line distance b is set to 80; the shot line distance c of the narrow azimuth seismic data is set to 150, and the detection line distance d is set to 300. Subsequently, the line distance information corresponding to the wide azimuth seismic data and the narrow azimuth seismic data can be used to perform seismic data splicing operations.

[0074] Step S104, constructing a plurality of wide azimuth cross gathers according to the wide azimuth seismic data, and constructing a plurality of narrow azimuth cross gathers according to the narrow azimuth seismic data.

[0075] Specifically, after the wide azimuth seismic data and narrow azimuth seismic data are obtained as mentioned above, in order to realize the splicing of the wide azimuth seismic data and the narrow azimuth seismic data, cross-cross gathers can be extracted for the wide azimuth seismic data and the narrow azimuth seismic data to obtain multiple wide azimuth cross-cross gathers and narrow azimuth cross-cross gathers, which are used to complete the splicing operation of the seismic data in the facet dimension.

[0076] Among them, the wide azimuth cross gather specifically refers to the gather constructed by selecting the shot lines and detection lines with an intersecting relationship in the wide azimuth seismic data. Correspondingly, the narrow azimuth cross gather specifically refers to the gather constructed by selecting the shot lines and detection lines with an intersecting relationship in the narrow azimuth seismic data.

[0077] Furthermore, when constructing wide azimuth cross gathers and narrow azimuth cross gathers, considering that both wide azimuth seismic data and narrow azimuth seismic data contain multiple detection lines and shot lines, it is necessary to construct cross gathers in combination with the intersection relationship between each detection line and shot line. In this embodiment, the construction of any one of the multiple wide azimuth cross gathers includes:

[0078] Selecting a target wide azimuth detection line from the wide azimuth seismic data, and selecting a target wide azimuth shot line that has an intersection relationship with the target wide azimuth detection line from the wide azimuth seismic data; constructing a wide azimuth cross gather based on the intersection relationship between the target wide azimuth detection line and the target wide azimuth shot line;

[0079] Among them, the construction of any one narrow azimuth cross-gather among the multiple narrow azimuth cross-gathers includes: selecting a target narrow azimuth detection line in the narrow azimuth seismic data, and selecting a target narrow azimuth shot line that has an intersection relationship with the target narrow azimuth detection line in the narrow azimuth seismic data; and constructing a narrow azimuth cross-gather based on the intersection relationship between the target narrow azimuth detection line and the target narrow azimuth shot line.

[0080] Specifically, the target wide azimuth detection line specifically refers to any detection line in the wide azimuth seismic data, and accordingly, the target wide azimuth shot line specifically refers to any shot line that has an intersection relationship with the target wide azimuth detection line. Correspondingly, the target narrow azimuth detection line specifically refers to any detection line in the narrow azimuth seismic data, and accordingly, the target narrow azimuth shot line specifically refers to any shot line that has an intersection relationship with the target narrow azimuth detection line.

[0081] Based on this, when constructing a cross-cross gather by combining wide-azimuth seismic data and narrow-azimuth seismic data, for the construction of any wide-azimuth cross-cross gather among any multiple wide-azimuth cross-cross gathers, the target wide-azimuth detection line can be selected in the wide-azimuth seismic data, and the target wide-azimuth shot line that has an intersection relationship with the target wide-azimuth detection line can be selected in the wide-azimuth seismic data; on this basis, the wide-azimuth cross-cross gather can be constructed based on the intersection relationship between the target wide-azimuth detection line and the target wide-azimuth shot line; similarly, for the construction of any narrow-azimuth cross-cross gather among multiple narrow-azimuth cross-cross gathers, the target narrow-azimuth detection line can be selected in the narrow-azimuth seismic data, and the target narrow-azimuth shot line that has an intersection relationship with the target narrow-azimuth detection line can be selected in the narrow-azimuth seismic data; the narrow-azimuth cross-cross gather can be constructed based on the intersection relationship between the target narrow-azimuth detection line and the target narrow-azimuth shot line.

[0082] In practical applications, considering that the shot points and the detection points are arranged linearly during onshore 3D seismic acquisition, we can refer to the field acquisition observation system and extract the seismic traces of all shots with signals received in an arrangement in any detection line and any shot line intersecting with it for wide and narrow azimuth seismic data, and form a new gather, which is used as a wide and narrow azimuth cross gather. By analogy, all shot lines and detection lines involved in wide and narrow azimuth seismic data are traversed to obtain multiple wide azimuth cross gathers and multiple narrow azimuth cross gathers.

[0083] It should be noted that the cross gather can obtain a rectangular reflection surface element distribution in the orthogonal observation system. In the direction parallel to the detection line, the reflection points come from the same shot, and in the direction parallel to the shot line, the reflection points are received from the same detection point. Therefore, the reflection points of a cross gather cover a continuous area, forming a single-coverage three-dimensional gather data volume.

[0084] Using the above example, after obtaining wide-azimuth seismic data and narrow-azimuth seismic data, the cross-gather extraction operation can be performed according to the above cross-gather extraction rules; in the orthogonal acquisition observation system, the intersection relationship between the detection line and the shot line in the wide-azimuth seismic data is as follows: Figure 2a As shown in , each detection line has multiple detection points, and each shot line has multiple shot points. After extracting the wide azimuth cross gather according to the above cross gather extraction rules, the following can be obtained: Figure 2b The wide azimuth cross gather shown; for example Figure 2aThe intersection relationship shown in the figure can obtain 36 wide azimuth cross gathers; similarly, the narrow azimuth seismic data can be processed in the same way as the wide azimuth seismic data to extract cross gathers, and multiple narrow azimuth cross gathers can be obtained. Subsequently, seismic data splicing operations can be performed based on the wide azimuth cross gathers and narrow azimuth cross gathers.

[0085] In summary, by constructing cross-gathers in the same way, it is possible to achieve the same splicing results in the same dimension when splicing data later, thereby ensuring the accuracy and efficiency of seismic data splicing.

[0086] Step S106, binning each wide azimuth cross gather according to the wide azimuth line spacing information, and constructing wide azimuth bin gathers according to the binning result.

[0087] Specifically, after obtaining multiple wide azimuth cross-gathers as mentioned above, in order to realize the merging of wide azimuth seismic data and narrow azimuth seismic data and avoid the arcing problem, each wide azimuth cross-gather can be first divided into facets according to the wide azimuth line spacing information, so as to obtain wide azimuth facet gathers in the facet dimension according to the division result, so that the narrow azimuth seismic data can be subsequently mapped to the facet dimension to achieve the purpose of seismic data splicing.

[0088] The wide-azimuth face element gather specifically refers to a set of multiple wide-azimuth face elements obtained according to the division results after face element division for each wide-azimuth cross-gather, and the wide-azimuth face elements contained in the gather are OVT face elements obtained after the wide-azimuth seismic data are mapped to the OVT domain.

[0089] Furthermore, when constructing wide azimuth bin gathers, considering that there are multiple wide azimuth cross gathers, in order to facilitate subsequent data splicing, bin division can be performed in combination with line distance information, and the collection can be constructed based on the bin division. In this embodiment, the specific implementation method is as follows:

[0090] Determine the target wide azimuth shot line spacing information according to the wide azimuth shot line spacing information, and determine the target wide azimuth detection line spacing information according to the wide azimuth detection line spacing information; perform facet division on each wide azimuth cross gather according to the target wide azimuth shot line spacing information and the target wide azimuth detection line spacing information to obtain a wide azimuth face element set corresponding to each wide azimuth cross gather; wherein the wide azimuth face elements contained in each wide azimuth face element set are configured with wide azimuth face element identifiers; select wide azimuth face elements with the same wide azimuth face element identifiers from the wide azimuth face element set corresponding to each wide azimuth cross gather to form a wide azimuth face element gather.

[0091] Specifically, the target wide azimuth shot line spacing information specifically refers to the shot line spacing information calculated by the two-fold relationship of the wide azimuth shot line spacing information; correspondingly, the target wide azimuth detection line spacing information specifically refers to the detection line spacing information calculated by the two-fold relationship of the wide azimuth detection line spacing information; correspondingly, the wide azimuth face element set specifically refers to the face element set composed of the OVT face elements associated with each wide azimuth cross gather obtained after face element division of each wide azimuth cross gather according to the target wide azimuth shot line spacing information and the target wide azimuth detection line spacing information, and after the gather is mapped to the OVT domain according to the division result. Correspondingly, the wide azimuth face element identifier specifically refers to the face element number corresponding to the wide azimuth face element contained in the wide azimuth face element set.

[0092] Based on this, when constructing a wide azimuth facet gather, the target wide azimuth shot line spacing information can be first determined according to the wide azimuth shot line spacing information, and the target wide azimuth detection line spacing information can be determined according to the wide azimuth detection line spacing information; thereafter, each wide azimuth cross gather can be faceted according to the target wide azimuth shot line spacing information and the target wide azimuth detection line spacing information, so as to map the wide azimuth cross gather to the OVT domain, so as to obtain a wide azimuth facet set corresponding to each wide azimuth cross gather according to the division result; wherein the wide azimuth facets contained in each wide azimuth facet set are configured with wide azimuth facet identifiers; thereafter, wide azimuth facets with the same wide azimuth facet identifiers can be selected from the wide azimuth facet set corresponding to each wide azimuth cross gather to form a wide azimuth facet gather for subsequent seismic data splicing operations.

[0093] For example, p wide azimuth face element sets corresponding to p wide azimuth cross gathers are obtained, wherein each wide azimuth face element set contains o wide azimuth face elements, and when wide azimuth face elements with the same wide azimuth face element identifiers are selected from each wide azimuth face element set to form a wide azimuth face element gather, o wide azimuth face element gathers can be obtained, and there are p wide azimuth face elements in each wide azimuth face element gather.

[0094] In practical applications, when performing OVT bin division and OVT gather extraction of wide azimuth seismic data, each wide azimuth cross gather can be divided and numbered according to the parameters of 2a in the shot line distance direction and 2b in the detection line distance direction. Among them, the numbering principle can be that in the wide azimuth cross gather, the intersection of the shot line and the detection line is used as the coordinate origin (0,0), and the OVT bins are used as units to sort upward and rightward, and the numbers are incremented, and recorded as positive values; the OVT bins are used as units to sort downward and leftward, and the numbers are incremented, and recorded as negative values; for example, the third OVT bin from the right and the fifth OVT bin from the bottom are recorded as (3, -5). Then all OVT bins with the same number are extracted to form an OVT gather, that is, a wide azimuth bin gather for subsequent use.

[0095] Among them, the OVT facet can be understood as one of the cells divided in the cross-gather with a width of 2 times the shot line spacing and 2 times the detection line spacing. The seismic traces in the cell have approximately the same shot offset and azimuth, and the underground reflection range reflected by the cell is the size of a cmp facet. The OVT facet refers to the collection of OVT facets with the same number in all cross-gathers, and the seismic traces in the collection have approximately the same shot offset and azimuth. Under regular acquisition, it is a three-dimensional seismic data volume with a single coverage.

[0096] It should be noted that when numbering each wide azimuth face element contained in the wide azimuth face element set, in order to facilitate the subsequent data splicing operation, a one-dimensional value can be used for numbering. On this basis, after obtaining the data pair of each face element, in order to avoid negative values, x and y in the data pair (x, y) can be added with a value greater than the number of coverages, and then merged together as the wide azimuth face element identifier (number) corresponding to the face element. For example, when the current coverage is less than 1000 at this time, the conversion formula can be (x+1000)*10000+y+1000. For example, for the data pair (3, -5), it can be converted to (1000+3)*10000+(1000-5)=10030995. 10030995 can be used as the wide azimuth face element identifier of the wide azimuth face element corresponding to the data pair (3, -5). In specific implementation, the operation of numbering each wide azimuth face element can be set according to actual needs, and this embodiment does not make any restrictions here.

[0097] Using the above example, after obtaining multiple wide azimuth cross gathers corresponding to wide azimuth seismic data, and the shot line spacing a=150 and the detection line spacing b=80 of the wide azimuth seismic data, the multiple wide azimuth cross gathers corresponding to the wide azimuth seismic data can be further divided and numbered into OVT bins according to the parameters of 2a=300 meters in the shot line spacing direction and 2b=160 meters in the detection line spacing direction; in order to facilitate the later gather extraction operation, the origin X and Y can be added with an integer much larger than the number of times the acquisition area is covered, and each OVT bin can be numbered according to the above numbering rules, so that the OVT bin set corresponding to each wide azimuth cross gather after the OVT bin division can be obtained; such as Figure 2c In the schematic diagram shown in FIG. 1 , the OVT bin (2,2) is divided and numbered, and the numbered OVT bin (2,2) is 10021002. After that, the OVT bins with the same number can be selected from the OVT bin sets corresponding to each wide azimuth cross gather to form a wide azimuth OVT bin gather, such as Figure 2d The schematic diagram of the gather extraction is shown; so that the wide azimuth OVT bin gather and the narrow azimuth OVT bin gather can be spliced ​​later, thereby achieving the purpose of seismic data splicing.

[0098] In summary, when constructing wide-azimuth bin gathers, in order to ensure that the wide-azimuth bins and their corresponding wide-azimuth bin identifiers are unique and support seismic data splicing operations, bins can be swapped according to the set shot line distance information and detection line distance information, and then wide-azimuth bins with the same bin identifiers are selected to form wide-azimuth bin gathers.

[0099] Step S108, mapping the narrow azimuth line spacing information into target narrow azimuth line spacing information using the wide azimuth line spacing information, performing binning on each narrow azimuth cross gather according to the target narrow azimuth line spacing information, and constructing narrow azimuth bin gathers according to the binning result.

[0100] Specifically, after completing the construction of the wide azimuth face element gather for the wide azimuth seismic data as mentioned above, in order to realize the splicing operation of the wide azimuth seismic data and the narrow azimuth seismic data, and to avoid the problem of coverage number difference caused by the splicing operation, the narrow azimuth line distance information can be first mapped to the target narrow azimuth line distance information using the wide azimuth line distance information, and then each narrow azimuth cross-gather is divided into face elements according to the target narrow azimuth line distance information, so as to obtain the narrow azimuth face element gather in the face element dimension according to the division result, so as to achieve the purpose of seismic data splicing.

[0101] Among them, the target narrow azimuth line spacing information specifically refers to the narrow azimuth line spacing information obtained by mapping the narrow azimuth line spacing information with the wide azimuth line spacing information. Correspondingly, the narrow azimuth surface element gather specifically refers to a set of multiple narrow azimuth surface elements obtained according to the division result after surface element division for each narrow azimuth cross gather, and the narrow azimuth surface elements contained in the gather are OVT surface elements obtained after the narrow azimuth seismic data are mapped to the OVT domain.

[0102] Furthermore, in order to achieve the splicing of wide-azimuth seismic data and narrow-azimuth seismic data and avoid the problem of abnormal coverage, the wide-azimuth line distance information can be used to map the narrow-azimuth line distance information, so that the two can be aligned before performing facet division, so as to facilitate the subsequent merging of seismic data. In this embodiment, the specific implementation method is as follows:

[0103] The shot line spacing mapping coefficient is calculated according to the wide azimuth shot line spacing information and the narrow azimuth shot line spacing information, and the detection line spacing mapping coefficient is calculated according to the wide azimuth detection line spacing information and the narrow azimuth detection line spacing information; the target narrow azimuth shot line spacing information is constructed based on the narrow azimuth shot line spacing information and the shot line spacing mapping coefficient, and the target narrow azimuth detection line spacing information is constructed based on the narrow azimuth detection line spacing information and the detection line spacing mapping coefficient; the target narrow azimuth shot line spacing information and the target narrow azimuth detection line spacing information are used as the target narrow azimuth line spacing information.

[0104] Specifically, the shot line distance mapping coefficient specifically refers to the ratio of the wide azimuth shot line distance information and the narrow azimuth shot line distance information and the coefficient obtained by rounding off to an integer; accordingly, the detection line distance mapping coefficient specifically refers to the ratio of the wide azimuth detection line distance information and the narrow azimuth detection line distance information and the coefficient obtained by rounding off to an integer; accordingly, the target narrow azimuth shot line distance information specifically refers to the shot line distance information obtained by calculating according to the narrow azimuth shot line distance information and the shot line distance mapping coefficient. Accordingly, the target narrow azimuth detection line distance information specifically refers to the detection line distance information obtained by calculating according to the narrow azimuth detection line distance information and the detection line distance mapping coefficient.

[0105] Based on this, when performing the mapping calculation of the target narrow azimuth line distance information, the gun line distance mapping coefficient can be first calculated according to the wide azimuth gun line distance information and the narrow azimuth gun line distance information, and the detection line distance mapping coefficient can be calculated according to the wide azimuth detection line distance information and the narrow azimuth detection line distance information; after obtaining the coefficients, the target narrow azimuth gun line distance information can be constructed based on the narrow azimuth gun line distance information and the gun line distance mapping coefficient, and the target narrow azimuth detection line distance information can be constructed based on the narrow azimuth detection line distance information and the detection line distance mapping coefficient; thereby, the target narrow azimuth gun line distance information and the target narrow azimuth detection line distance information can be used as the target narrow azimuth line distance information.

[0106] In practical applications, the shot line spacing mapping coefficient can be obtained by calculating the ratio of the narrow azimuth shot line spacing information to the wide azimuth shot line spacing information and rounding it off to an integer. The detection line spacing mapping coefficient can be obtained by calculating the ratio of the narrow azimuth detection line spacing information to the wide azimuth detection line spacing information and rounding it off to an integer. The expressions are m=c / a, n=d / b, and m and n are rounded off to obtain m' (shot line spacing mapping coefficient) and n' (detection line spacing mapping coefficient).

[0107] On this basis, the target narrow azimuth shot line distance information calculated according to the relationship 2*c / m' and the target narrow azimuth detection line distance information calculated according to the relationship 2*d / n' can be used for subsequent bin division and numbering, so as to construct narrow azimuth bin gathers and perform seismic data splicing operations.

[0108] Furthermore, when constructing narrow azimuth bin gathers, considering that there are multiple narrow azimuth cross gathers, in order to facilitate subsequent data splicing, bin division can be performed in combination with line distance information, and the collection can be constructed based on the bin division. In this embodiment, the specific implementation method is as follows:

[0109] Each narrow azimuth cross-gather is divided into facets according to the target narrow azimuth shot line spacing information and the target narrow azimuth detection line spacing information to obtain a narrow azimuth facet set corresponding to each narrow azimuth cross-gather; narrow azimuth facets with adjacent relationship in the narrow azimuth facet set corresponding to each narrow azimuth cross-gather are combined, and a combined narrow azimuth facet set corresponding to each narrow azimuth cross-gather is determined according to the combination result; wherein, the combined narrow azimuth facets contained in each combined narrow azimuth facet set are configured with combined narrow azimuth facet identifiers; and combined narrow azimuth facets with the same combined narrow azimuth facet identifiers are selected from the combined narrow azimuth facet set corresponding to each narrow azimuth cross-gather to form a narrow azimuth facet gather.

[0110] The construction of the combined narrow azimuth bin set corresponding to any narrow azimuth cross gather includes:

[0111] In the narrow azimuth cross gather, a plurality of narrow azimuth surface elements that match the shot line spacing mapping coefficient and the detection line spacing mapping coefficient are screened; wherein the plurality of narrow azimuth surface elements are in a positionally adjacent relationship; and the plurality of narrow azimuth surface elements are combined to obtain a combined narrow azimuth surface element set corresponding to the narrow azimuth cross gather.

[0112] Specifically, the narrow azimuth face element set specifically refers to the face element set consisting of the OVT face elements associated with each narrow azimuth cross-cross gather, which is obtained after the gathers are mapped to the OVT domain according to the division results after each narrow azimuth cross-cross gather is faceted according to the target narrow azimuth shot line spacing information and the target narrow azimuth detection line spacing information. Correspondingly, the combined narrow azimuth face element set specifically refers to the face element set consisting of the combined narrow azimuth face elements obtained after combining the narrow azimuth face elements with adjacent relationships in the narrow azimuth face element set corresponding to each narrow azimuth cross-cross gather. Correspondingly, the combined narrow azimuth face element identifier specifically refers to the face element number corresponding to the combined narrow azimuth face element contained in the combined narrow azimuth face element set.

[0113] Based on this, when constructing narrow azimuth facet gathers, each narrow azimuth cross-gather can be first divided into facets according to the target narrow azimuth shot line distance information and the target narrow azimuth detection line distance information, so as to map the narrow azimuth cross-gathers to the OVT domain, so as to obtain the narrow azimuth facet set corresponding to each narrow azimuth cross-gather according to the division result; on this basis, in order to realize the splicing operation of seismic data, the narrow azimuth facets with adjacent relationships in the narrow azimuth facet set corresponding to each narrow azimuth cross-gather can be combined, so as to determine the combined narrow azimuth facet set corresponding to each narrow azimuth cross-gather according to the combination result; wherein, the combined narrow azimuth facets contained in each combined narrow azimuth facet set are configured with a combined narrow azimuth facet identifier; finally, the combined narrow azimuth facets with the same combined narrow azimuth facet identifier are selected from the combined narrow azimuth facet set corresponding to each narrow azimuth cross-gather to form a narrow azimuth facet gather.

[0114] It should be noted that, in the process of constructing the narrow azimuth face element set, except for the different face element division parameters, the process is similar to the description of the construction process of the wide azimuth face element set. The contents not described in detail in this embodiment can refer to the same or corresponding description in the above embodiment, and this embodiment will not be repeated in detail here.

[0115] That is to say, after obtaining the narrow azimuth face element set, in order to facilitate the subsequent seismic data splicing operation, the divided narrow azimuth face element set can be extracted with vertically continuous m' and horizontally continuous n' adjacent numbered OVT face elements to form a macro OVT face element, that is, adjacently numbered narrow azimuth face elements are selected to form a combined narrow azimuth face element, and the combination operation is basically consistent with the face element size when the narrow azimuth seismic data is divided by 2c and 2d, and it is named with the number at the same position as the wide azimuth data. Therefore, a combined narrow azimuth face element set can be obtained according to the combination result. After obtaining the combined narrow azimuth face element set, the same renumbered macro OVT face elements can be selected in each combined narrow azimuth face element set to form an OVT data set, that is, a narrow azimuth face element data set, for subsequent splicing operations.

[0116] Using the above example, after obtaining multiple narrow azimuth cross gathers corresponding to narrow azimuth seismic data, and the shot line spacing c=150 and the detection line spacing d=300 of the narrow azimuth seismic data, further, by calculation, m=150 / 150 and n=300 / 80=3.75 are determined. Therefore, after rounding to integers, the shot line spacing mapping coefficient m'=1 and the detection line spacing mapping coefficient n'=4 are determined. On this basis, for each narrow azimuth cross gather, the OVT bins can be divided and numbered according to the parameters of 2×(150 / 1)=300 in the shot line direction and 2×(300 / 4)=150 in the detection line spacing direction. After division and numbering, a narrow azimuth bin set will be obtained. After that, one vertically continuous OVT bin and four horizontally continuous adjacently numbered OVT bins can be extracted from each narrow azimuth bin set to form a macro OVT bin, which is basically the same size as the bin when the narrow azimuth seismic data is divided into 300 and 600 bins, and is named with the same number as the wide azimuth seismic data. Figure 2e As shown, in the narrow azimuth cross gathers extracted from narrow azimuth seismic data, taking the OVT facets with the same number as the wide azimuth facets as the reference, one is extracted to the left and two are extracted to the right, and these four consecutive OVT facets are renamed as 10011002', and so on. After processing each narrow azimuth facet, multiple combined narrow azimuth facet sets can be obtained. Finally, for the combined narrow azimuth facet set corresponding to each narrow azimuth cross gather, the macro OVT facets with the same number are selected to form a narrow azimuth OVT facet gather, and the subsequent splicing operation can be realized.

[0117] In summary, by mapping the narrow-azimuth seismic data to the same dimension as the wide-azimuth seismic data for binning, it can be ensured that the two have the same properties under the splicing mechanism. Splicing the seismic data on this basis can ensure splicing efficiency and accuracy.

[0118] Step S110, performing bin splicing on the wide azimuth bin gather and the narrow azimuth bin gather, and generating target seismic data according to the splicing result.

[0119] Specifically, after obtaining the wide azimuth face element gathers corresponding to the wide azimuth seismic data and the narrow azimuth face element gathers corresponding to the narrow azimuth seismic data, the alignment of the two in the OVT domain has been achieved. Therefore, by performing face element splicing on the wide azimuth face element gathers and the narrow azimuth face element gathers, the target seismic data can be generated according to the splicing results, so that the downstream can use the target seismic data for subsequent business processing.

[0120] Furthermore, when performing bin splicing processing from the bin gather dimension, it is actually a process of splicing by selecting seismic data with the same identification. In this embodiment, the specific implementation method is as follows:

[0121] Target wide azimuth bins and target narrow azimuth bins with the same bin identifiers are selected from the wide azimuth bin gathers and the narrow azimuth bin gathers for splicing, and target seismic data are generated according to the splicing results.

[0122] Based on this, when splicing the wide azimuth face element gathers and the narrow azimuth face element gathers, considering that the wide azimuth face element gathers and the narrow azimuth face element gathers have the same face element identification numbering rules, by selecting the target wide azimuth face elements and the target narrow azimuth face elements with the same face element identification in the wide azimuth face element gathers and the narrow azimuth face element gathers for splicing, the target seismic data can be generated according to the splicing results.

[0123] In addition, considering that there are still some remaining wide azimuth bins and narrow azimuth bins in the wide azimuth bin gather after splicing, in order to ensure that the seismic data is convenient for subsequent use, the splicing result and the remaining wide azimuth bins can be combined to construct the target seismic data. In this embodiment, the specific implementation method is as follows:

[0124] In the wide azimuth face element gather and the narrow azimuth face element gather, target wide azimuth face elements and target narrow azimuth face elements with the same face element identifiers are selected for splicing to obtain initial seismic data; when it is detected that there are remaining wide azimuth face elements in the wide azimuth face element gather, target seismic data are generated according to the remaining wide azimuth face elements and the initial seismic data.

[0125] Specifically, the initial seismic data refers to the seismic data obtained by splicing the target wide azimuth bins and the target narrow azimuth bins with the same bin identifier; correspondingly, the remaining wide azimuth bins refer to the other wide azimuth bins remaining after the bins are spliced.

[0126] Based on this, when performing the splicing operation, the target wide azimuth face elements and the target narrow azimuth face elements with the same face element identifiers can be selected from the wide azimuth face element gather and the narrow azimuth face element gather for splicing to obtain the initial seismic data; thereafter, if it is detected that there are remaining wide azimuth face elements in the wide azimuth face element gather, the target seismic data can be directly generated based on the remaining wide azimuth face elements and the initial seismic data for use by downstream businesses.

[0127] In practical applications, after selecting the same renumbered macro OVT facets in each combined narrow azimuth facet set to form an OVT gather, it can be put together with the OVT gather of the same number of the wide azimuth data for subsequent processing to complete the fusion processing of the wide and narrow azimuth data OVT domain. Repeat the above splicing operation for each numbered OVT facet until all numbers of the narrow azimuth data are extracted. The remaining numbered wide azimuth data are extracted separately, and the gather data are named according to the original number, thus completing the splicing processing of the wide and narrow azimuth data OVT domain.

[0128] Using the above example, Figure 2e As shown in the figure, after obtaining the wide azimuth OVT bin gather and the narrow azimuth OVT bin gather, the gathers with the same number in the two gathers can be fused in the OVT domain. After repeating the above splicing operation for each OVT bin, the wide azimuth data with the remaining numbers are extracted separately, and the gather data are named according to the original numbers. The OVT domain splicing of the wide and narrow azimuth data is completed. After the OVT domain splicing and fusion processing, the offset arcing problem caused by the number of coverage can be effectively eliminated, and the profile imaging quality can be significantly improved. The azimuth information is retained, laying a data foundation for the subsequent study of equal azimuth for fracture prediction.

[0129] The data splicing method provided in the present embodiment can first collect wide-azimuth seismic data and narrow-azimuth seismic data in order to effectively eliminate the problem of arcing of offset imaging caused by the difference in the number of times adjacent data are covered. Thereafter, the wide-azimuth line spacing information corresponding to the wide-azimuth seismic data and the narrow-azimuth line spacing information corresponding to the narrow-azimuth seismic data can be determined. On this basis, in order to ensure that the wide-azimuth seismic data and the narrow-azimuth seismic data can be spliced ​​more reasonably, a plurality of wide-azimuth cross-gathers can be first constructed based on the wide-azimuth seismic data, and a plurality of narrow-azimuth cross-gathers can be constructed based on the narrow-azimuth seismic data. Thereafter, for the wide-azimuth seismic data, each wide-azimuth cross-gather can be constructed according to the wide-azimuth line spacing information. The cross gather is divided into planes, and a wide azimuth plane gather is constructed according to the plane division results; on this basis, in order to be able to effectively splice and improve efficiency without relying on third-party processing software, the narrow azimuth line distance information can be mapped to the target narrow azimuth line distance information using the wide azimuth line distance information, and then each narrow azimuth cross gather is divided into planes according to the target narrow azimuth line distance information, and a narrow azimuth plane gather is constructed according to the plane division results; after obtaining the wide azimuth plane gather and the narrow azimuth plane gather that have an aligned relationship in the attribute dimension, the wide azimuth plane gather and the narrow azimuth plane gather can be plane spliced, so that the target seismic data can be generated according to the splicing results. When splicing wide azimuth seismic data and narrow azimuth seismic data, it can be completed under the premise of retaining the azimuth information of the original data, and the difference in the number of coverage times can be eliminated, thereby greatly shortening the data processing cycle and making it more convenient for subsequent seismic research.

[0148] Step S330, when it is detected that there are remaining wide azimuth bins in the wide azimuth bin gathers, target seismic data are generated according to the remaining wide azimuth bins and the initial seismic data.

[0149] To summarize, in order to effectively eliminate the problem of arcing in offset imaging caused by the difference in the number of adjacent data coverages, wide-azimuth seismic data and narrow-azimuth seismic data can be collected first, and then the wide-azimuth line spacing information corresponding to the wide-azimuth seismic data and the narrow-azimuth line spacing information corresponding to the narrow-azimuth seismic data can be determined; on this basis, in order to ensure that the wide-azimuth seismic data and the narrow-azimuth seismic data can be spliced ​​more reasonably, multiple wide-azimuth cross-gathers can be constructed based on the wide-azimuth seismic data, and multiple narrow-azimuth cross-gathers can be constructed based on the narrow-azimuth seismic data; thereafter, for the wide-azimuth seismic data, each wide-azimuth cross-gather can be processed according to the wide-azimuth line spacing information. Facet division, construct wide azimuth facet gathers according to facet division results; on this basis, in order to be able to effectively splice and improve efficiency without relying on third-party processing software, the narrow azimuth line distance information can be mapped to the target narrow azimuth line distance information using the wide azimuth line distance information, and then facet division is performed on each narrow azimuth cross gather according to the target narrow azimuth line distance information, and narrow azimuth facet gathers are constructed according to the facet division results; after obtaining wide azimuth facet gathers and narrow azimuth facet gathers with alignment relationship in attribute dimension, facet splicing can be performed on wide azimuth facet gathers and narrow azimuth facet gathers, so that target seismic data can be generated according to the splicing results. When splicing wide azimuth seismic data and narrow azimuth seismic data, it can be completed under the premise of retaining the azimuth information of the original data, and the difference in the number of coverage times can be eliminated, thereby greatly shortening the data processing cycle and making it more convenient for subsequent seismic research.
