[0002] With the advancement of geophysical exploration technology, people have begun to conduct seismic exploration in various locations, generating more and more seismic data. In order to classify and store the complex seismic data, it is necessary to convert the storage format of the seismic data to save storage space and facilitate retrieval.

[0003] Existing seismic data storage format conversion technologies are mostly based on storage formats categorized by recording method. For example, standard seismic storage formats such as the SEG series, LTOD, RODE, and SU series data storage formats often lack records of the data exploration equipment and exploration status during use. This can lead to missing basic information about the seismic data, causing subsequent data interpretation failures and resulting in incomplete storage information during format conversion. Summary of the Invention

[0004] This invention provides a method, apparatus, and computer-readable storage medium for converting the storage format of seismic data, with the main objective of solving the problem of insufficient storage information during storage format conversion.

[0005] To achieve the above objectives, the present invention provides a method for converting the storage format of seismic data, comprising:

[0006] Feature extraction is performed on the pre-acquired seismic data to obtain seismic data features. Based on the seismic data features, the seismic data is then divided into seismic data creation information, seismic data acquisition equipment information, seismic data acquisition status information, seismic data acquisition method information, seismic equipment usage status information, seismic trace vibration information, and supplementary information for the seismic trace vibration information.

[0007] The earthquake data creation information, earthquake data acquisition equipment information, earthquake data acquisition status information, earthquake data acquisition method information, and earthquake equipment usage status information are compiled into a data header set, and the data header set is format-converted to obtain an earthquake data header array.

[0008] The seismic trace vibration information is XORed to form a vibration array, the supplementary information format is converted into a supplementary array, and the vibration array and the supplementary array are concatenated to form a seismic trace array;

[0009] The seismic data header array and the seismic trace array are concatenated to form standard seismic data, thus completing the conversion of the seismic data storage format.

[0010] Optionally, the earthquake data creation information includes file tags, file version, file creation reason, file end description, file end reason, and file index.

[0011] Optionally, the seismic data acquisition equipment information includes the acquisition equipment type, acquisition equipment SN number, acquisition equipment component number, data acquisition project name, total acquisition channels of the data acquisition project, current acquisition channel of the data acquisition project, firmware loading version of the acquisition equipment, and firmware application version of the acquisition equipment.

[0015] Optionally, the seismic trace vibration information includes several data blocks, and each data block includes several seismic data points such as vibration displacement, vibration velocity, and vibration acceleration.

[0016] To address the above problems, the present invention also provides a seismic data storage format conversion device, the device comprising:

[0017] The data splitting module is used to extract features from the pre-acquired seismic data to obtain seismic data features, and to split the seismic data into seismic data creation information, seismic data acquisition equipment information, seismic data acquisition status information, seismic data acquisition method information, seismic equipment usage status information, seismic trace vibration information, and supplementary information of the seismic trace vibration information based on the seismic data features.

[0018] The header conversion module is used to collect the earthquake data creation information, earthquake data acquisition equipment information, earthquake data acquisition status information, earthquake data acquisition method information, and earthquake equipment usage status information into a data header set, and to convert the format of the data header set to obtain an earthquake data header array.

[0019] The tail segment conversion module is used to perform an XOR operation on the vibration information of the seismic trace into a vibration array, convert the supplementary information format into a supplementary array, and concatenate the vibration array and the supplementary array into a seismic trace array;

[0020] The data stitching module is used to stitch the seismic data header array and the seismic trace array into standard seismic data, thereby completing the conversion of the seismic data storage format.

[0024] The memory stores a computer program that can be executed by the at least one processor, which enables the at least one processor to perform the above-described method for converting the storage format of seismic data.

[0025] To address the aforementioned problems, the present invention also provides a computer-readable storage medium storing at least one computer program, which is executed by a processor in an electronic device to implement the aforementioned method for converting the storage format of seismic data.

[0026] This invention extracts features from pre-acquired seismic data to obtain seismic data features, facilitating subsequent classification of the seismic data. By splitting the seismic data into seismic data creation information, seismic data acquisition equipment information, seismic data acquisition status information, seismic data acquisition method information, seismic equipment usage status information, seismic trace vibration information, and supplementary information for the seismic trace vibration information, it can comprehensively record the acquisition and equipment-related data corresponding to the seismic data, compensating for the shortcomings of commonly used standard seismic data recording formats such as SEG-Y. By including the seismic data creation information and the seismic data acquisition equipment information... The seismic data acquisition status information, seismic data acquisition method information, and seismic equipment usage status information are aggregated into a data header set. This data header set is then format-converted to obtain a seismic data header array, effectively reducing the space occupied by the data header set and increasing data storage density. By XORing the seismic trace vibration information into a vibration array, converting the supplementary information format into a supplementary array, and concatenating the vibration array and the supplementary array into a seismic trace array, the key vibration data of the earthquake can be converted and stored using the vibration array, and the key vibration data can be supplemented using the supplementary array, thereby increasing data storage density. Therefore, the seismic data storage format conversion method, apparatus, electronic device, and computer-readable storage medium proposed in this invention can improve the comprehensiveness of stored information during seismic data storage format conversion.

[0088] In this embodiment of the invention, by extracting features from pre-acquired seismic data, seismic data features are obtained, which facilitates subsequent classification of the seismic data. By splitting the seismic data into seismic data creation information, seismic data acquisition equipment information, seismic data acquisition status information, seismic data acquisition method information, seismic equipment usage status information, seismic trace vibration information, and supplementary information of the seismic trace vibration information according to the seismic data features, the acquisition and equipment-related data corresponding to the seismic data can be recorded in detail, making up for the deficiencies of commonly used standard seismic data recording formats such as SEG-Y.

[0089] S2. The earthquake data creation information, earthquake data acquisition equipment information, earthquake data acquisition status information, earthquake data acquisition method information, and earthquake equipment usage status information are collected into a data header set, and the data header set is format-converted to obtain an earthquake data header array.

[0090] In this embodiment of the invention, the data header set is a data set containing multiple strings.

[0091] Specifically, the earthquake data header array occupies a total of 512 bytes.

[0092] In this embodiment of the invention, reference is made to Figure 3 As shown, the process of format conversion of the data header set to obtain the seismic data header array includes:

[0093] S31. Extract the first-level conversion element set from the data header set according to the data type, and classify the remaining elements in the data header set other than the first-level conversion element set according to the value range to obtain the second-level conversion element set and the third-level conversion element set.

[0094] S32. Perform base conversion on the elements in the first-level conversion element set to obtain a standard first-level element set;

[0095] S33. Perform character conversion and number system conversion on the elements in the set of secondary conversion elements in sequence to obtain a standard set of secondary elements;

[0096] S34. Encode the elements in the three-level transformation element set according to the total number of value range elements to obtain a standard three-level element set, and combine the elements in the standard first-level element set, the standard second-level element set, and the standard third-level element set into a header array.

[0097] In detail, extracting the first-level conversion element set from the data header set according to data type means adding the set elements with integer data type to the first-level conversion element set. For example, if the data type of the total acquisition channel of the data acquisition project and the current acquisition channel of the data acquisition project is integer, then the total acquisition channel of the data acquisition project and the current acquisition channel of the data acquisition project can be added to the first-level conversion element set.

[0098] Specifically, classifying the remaining elements in the data header set, excluding the first-level transformation element set, according to their value range to obtain a second-level transformation element set and a third-level transformation element set includes:

[0099] The standard data header set is obtained by deleting the element corresponding to the first-level transformation element set from the data header set.

[0100] Each element in the standard data header set is selected as a target element, and the total number of the target element's value range elements is taken as the target value range. It is then determined whether the target value range is greater than a preset value range threshold.

[0101] When the target value range is greater than the value range threshold, the target element is added to the secondary transformation element set;

[0102] When the target value range is less than or equal to the value range threshold, the target element is added to the three-level transformation element set.

[0103] Specifically, the threshold value can be 8 or 16.

[0104] Specifically, the total number of value range elements refers to the total number of selectable value objects corresponding to the target element. For example, when the value range of the file termination reason is (sudden termination, normal switching, entering sleep, battery depletion), the total number of corresponding value range elements is 4.

[0105] In detail, the step of converting the elements in the first-level conversion element set to obtain the standard first-level element set refers to converting the elements in the first-level conversion element set to hexadecimal and then assembling the converted elements into the standard first-level element set. For example, converting 16777216 to 01000000.

[0106] In detail, the step of sequentially performing character conversion and number system conversion on the elements in the second-level conversion element set to obtain a standard second-level element set includes:

[0107] Each element in the set of secondary transformation elements is selected as the target secondary element, and each character in the target secondary element is selected as the target secondary character in order from left to right.

[0108] The target secondary character is converted to obtain the target secondary character code;

[0109] The target two-level character code is converted to a different base to obtain a standard two-level character code;

[0110] All standard secondary character codes are assembled into a standard secondary string in the order corresponding to the target secondary element. The standard secondary string is padded with zeros to obtain the standard secondary element, and all standard secondary elements are assembled into a standard secondary element set.

[0111] In detail, the character conversion of the target secondary character to obtain the target secondary character code refers to converting the target secondary character to ASCII code to obtain the target secondary character code.

[0112] In detail, the elements in the set of secondary conversion elements are sequentially converted into characters and numbers to obtain a standard set of secondary elements. For example, when the element in the set of secondary conversion elements is 100614.00, the standard secondary element corresponding to 100614.00 is 3130303631342e3030.

[0113] In detail, encoding the elements in the three-level transformation element set according to the total number of value range elements to obtain the standard three-level element set means replacing the elements in the three-level transformation element set with the total number of corresponding value range elements, thereby obtaining the standard three-level element set.

[0114] In this embodiment of the invention, by aggregating the earthquake data creation information, earthquake data acquisition equipment information, earthquake data acquisition status information, earthquake data acquisition method information, and earthquake equipment usage status information into a data header set, and then converting the format of the data header set to obtain an earthquake data header array, the space occupied by the data header set can be effectively reduced and the data storage density can be improved.

[0115] S3. Perform an XOR operation on the seismic trace vibration information to form a vibration array, convert the supplementary information format into a supplementary array, and concatenate the vibration array and the supplementary array to form a seismic trace array.

[0116] In this embodiment of the invention, the step of XORing the seismic trace vibration information into a vibration array includes:

[0117] Each element in the seismic trace vibration information is selected as a target vibration element, and it is determined whether the target vibration element is a positive number.

[0118] When the target vibration element is a positive number, the target vibration element is converted into an XOR vibration element using the following first XOR formula:

[0119]

[0120] Where A refers to the XOR vibration element, Bin() is the binary conversion formula, a is the target vibration element, XOR is the bitwise XOR formula, Dec() is the decimal conversion formula, and Hex() is the hexadecimal conversion formula.

[0121] When the target vibration element is a non-positive number, the target vibration element is converted into an XOR vibration element using the following second XOR formula:

[0122]

[0123] Where A refers to the XOR vibration element, and Hex() is the hexadecimal conversion formula;

[0124] The XOR vibration elements are sorted in random order to obtain standard vibration elements, and all standard vibration elements are aggregated into a seismic trace array.

[0125] In this embodiment of the invention, by using the first XOR formula or the second XOR formula to convert the target vibration element into an XOR vibration element, the consistency of the sign during the number system conversion can be ensured, and the density of the converted data can be improved.

[0126] In detail, the step of randomly sorting the XOR vibration elements to obtain standard vibration elements refers to splitting the XOR vibration elements into bytes and combining them in reverse order to obtain standard vibration elements.

[0127] In detail, the method of converting the supplementary information format into a supplementary array is the same as the method of converting the data header set into a format to obtain the seismic data header array in step S2 above, and will not be repeated here.

[0128] In this embodiment of the invention, by performing an XOR operation on the seismic trace vibration information to form a vibration array, converting the supplementary information format into a supplementary array, and concatenating the vibration array and the supplementary array into a seismic trace array, the key vibration data of an earthquake can be converted and stored using the vibration array, and the key vibration data can be supplemented using the supplementary array, thereby improving the data storage density.

[0129] S4. The seismic data header array and the seismic trace array are concatenated to form standard seismic data, thus completing the conversion of the seismic data storage format.

[0130] In this embodiment of the invention, feature extraction is performed on pre-acquired seismic data to obtain seismic data features, which facilitates subsequent classification of the seismic data. By splitting the seismic data into seismic data creation information, seismic data acquisition equipment information, seismic data acquisition status information, seismic data acquisition method information, seismic equipment usage status information, seismic trace vibration information, and supplementary information for the seismic trace vibration information based on these features, the acquisition and equipment-related data corresponding to the seismic data can be recorded in detail. This compensates for the deficiencies of commonly used standard seismic data recording formats such as SEG-Y. The seismic data acquisition status information, seismic data acquisition method information, and seismic equipment usage status information are aggregated into a data header set. This data header set is then format-converted to obtain a seismic data header array, effectively reducing the space occupied by the data header set and increasing data storage density. By XORing the seismic trace vibration information into a vibration array, converting the supplementary information format into a supplementary array, and concatenating the vibration array and the supplementary array into a seismic trace array, the vibratory array can be used to convert and store key seismic vibration data, and the supplementary array can be used to supplement the key vibration data, thereby increasing data storage density. Therefore, the seismic data storage format conversion method proposed in this invention can improve the comprehensiveness of stored information during seismic data storage format conversion.
