[0002] Before 2004, geological data from single wells in the petroleum industry were mainly stored on paper. Starting in 2004, with the development of computer technology, single-well geological data gradually began to be managed digitally. By 2014, the informatization of wellbore-related data, including drilling, logging, well logging, downhole operations, and analytical testing, was basically completed. However, single-well operations are mostly conducted in the field, and data is easily damaged during the process from acquisition to transmission to the target database. Therefore, there is an urgent need for a verification method to ensure data consistency during data transmission. Summary of the Invention

[0074] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0075] Figure 1 This is a flowchart of a wellbore data consistency verification method provided in this embodiment of the disclosure. See also: Figure 1 The consistency verification method for this wellbore data includes:

[0076] 101. Obtain the form to be transmitted, the form containing wellbore data.

[0077] Wellbore data refers to wellbore-related data, such as drilling, logging, well logging, downhole operations, analysis and testing data, etc., which are not limited in this application embodiment.

[0078] 102. Perform content conversion on the form to obtain a first array A, wherein the first array is the form represented by a character array.

[0079] 103. Divide the first array A into multiple data segments.

[0080] 104. Convert the multiple data fragments into Ulong type respectively to obtain the second array B.

[0081] 105. Obtain the first parameters SA1, SA2, SA3 and SA4.

[0082] 106. Using the first parameters SA1, SA2, SA3 and SA4 and the second array B as inputs to the MD5 checksum algorithm, the second parameters SA1', SA2', SA3' and SA4' are obtained.

[0083] 107. Generate a verification string S based on the second parameters SA1', SA2', SA3', and SA4'.

[0084] 108. The verification string S and the form are transmitted together to the second electronic device, wherein the verification string S is used by the second electronic device to verify the form.

[0085] The method provided in this application embodiment converts, segments, and performs secondary conversion on wellbore data, and obtains a check string based on the converted array and MD5 algorithm. This allows the check string to be transmitted simultaneously with the wellbore data, enabling the data receiving end to verify the wellbore data based on the check string. This achieves data consistency verification and ensures the consistency of wellbore data during transmission.

[0086] In one possible implementation, the step of converting the content of the form to obtain the first array A includes: obtaining the form content in the form, adding a first character to every two fields in the form content, and adding a second character between every two lines in the form content to obtain the first array A.

[0087] In one possible implementation, dividing the first array A into multiple data segments includes: obtaining the length of the first array A; dividing the length by a constant 64 to obtain the number of blocks; and dividing the first array A into multiple data segments according to the number of blocks.

[0088] In one possible implementation, obtaining the first parameters SA1, SA2, SA3, and SA4 includes: obtaining hexadecimal variables S1, S2, S3, and S4; and assigning four hexadecimal constants to the hexadecimal variables S1, S2, S3, and S4 to obtain the first parameters SA1, SA2, SA3, and SA4.

[0089] All of the above-mentioned optional technical solutions can be combined in any way to form optional embodiments of this disclosure, and will not be described in detail here.

[0090] Figure 2 This is a flowchart of a wellbore data consistency verification method provided in this embodiment of the disclosure. See also: Figure 2 The consistency verification method for this wellbore data includes:

[0091] 201. The first electronic device acquires a form to be transmitted, which contains wellbore data.

[0092] The first electronic device can be a wellbore data acquisition device, used to acquire wellbore data and generate a form based on the acquired wellbore data. The form can be in any format; for example, it can be a two-dimensional form.

[0093] 202. Perform content conversion on the form to obtain a first array A, wherein the first array is the form represented by a character array.

[0094] The first electronic device acquires the form content from the form, adds a first character between every two fields in the form content, and adds a second character between every two lines in the form content to obtain the first array A. When the form is a two-dimensional form, each line of the form includes multiple fields. Therefore, "\t" can be added between every two fields, and "\r" and "\n" can be added between every two lines to separate the fields and the lines, thus converting the two-dimensional form into a one-dimensional first array. Other symbols can also be used to separate fields and lines; this application embodiment does not limit this method.

[0095] 203. The first electronic device obtains the length of the first array A; divides the length by a constant 64 to obtain the number of blocks; and divides the first array A according to the number of blocks to obtain multiple data segments.

[0096] By dividing the length by a constant 64, the first array can be divided into multiple 64-bit data segments, ensuring that subsequent array transformations can be performed based on data segments of the same length. Of course, if the length of the first array exceeds the target length, when dividing based on the number of blocks, every 2N (where N is an integer greater than or equal to 1) 64-bit data segments can be divided into a single data fragment. That is, the division method can be adjusted according to the actual length of the first data segment, using 64 bits as the base fragment length, so that regardless of the division method, the number of data fragments obtained is the same, thus ensuring that the number of elements in the resulting second array is the same during subsequent processing.

[0097] 204. The first electronic device converts the multiple data fragments into Ulong type respectively to obtain the second array B.

[0098] Among them, Ulong (unsigned long integer) refers to storing characters as a 32-bit (4-byte) numerical form.

[0099] 205. The first electronic device acquires hexadecimal variables S1, S2, S3 and S4; sets four hexadecimal constants and assigns them to the hexadecimal variables S1, S2, S3 and S4 to obtain the first parameters SA1, SA2, SA3 and SA4.

[0100] Step 205 above describes the process by which the first electronic device acquires the first parameters SA1, SA2, SA3, and SA4. These four variables can be arbitrary, and this application does not impose any restrictions on them. The first electronic device can randomly generate four hexadecimal constants to assign values ​​to the above variables.

[0101] In some embodiments, the first electronic device can generate a corresponding hexadecimal constant based on its device information, such as device type and device identifier, so that when the data receiving end performs verification, it can ensure the legitimacy of the data sending device and avoid problems such as data tampering.

[0102] 206. The first electronic device uses the first parameters SA1, SA2, SA3 and SA4 and the second array B as inputs to the MD5 checksum algorithm to obtain the second parameters SA1', SA2', SA3' and SA4'.

[0103] After generating the first parameter, the first electronic device can input the generated first parameter and the second array B into the MD5 checksum generator. The generator uses the MD5 checksum algorithm to process the input data and obtain the second parameter.

[0104] In some embodiments, the first electronic device concatenates the first parameters SA1, SA2, SA3 and SA4 to the second array B to obtain the corresponding first intermediate parameters, and then inputs the multiple first intermediate parameters obtained by concatenation into the MD5 checksum generator to obtain the corresponding second parameters SA1', SA2', SA3' and SA4'.

[0105] In some embodiments, the first electronic device splits the second array B into four data segments, concatenates each data segment with the first parameters SA1, SA2, SA3 and SA4 respectively to obtain the corresponding second intermediate parameters, and then inputs the concatenated second intermediate parameters into an MD5 checksum generator to obtain the corresponding second parameters SA1', SA2', SA3' and SA4'.

[0106] The two processing methods described above are merely examples of generating the second parameter based on the first parameters SA1, SA2, SA3, and SA4 and the second array B. In other embodiments, the second parameter can also be generated based on the transformation of the second array and the multiple first parameters. This application does not limit this approach.

[0107] 207. The first electronic device generates a verification string S based on the second parameters SA1', SA2', SA3' and SA4'.

[0108] In the embodiments of this application, the above-mentioned verification string can be generated by concatenating multiple second parameters. In some embodiments, the first electronic device can concatenate the above-mentioned multiple second parameters in a preset order, for example, concatenating them in ascending order of parameter number or in descending order of parameter number, which is not limited here.

[0109] Of course, in some embodiments, the verification string can also be obtained based on the string obtained by concatenating multiple second parameters. For example, the first electronic device extracts the first preset number of characters from the string obtained after concatenation as the verification string to increase the complexity of subsequent verification and thus improve data security.

[0110] 208. The first electronic device transmits the verification string S and the form together to the second electronic device, whereby the verification string S is used by the second electronic device to verify the form.

[0111] After generating the verification string, the first electronic device can package the verification string and the form into a data packet and send it to the second electronic device. For example, the first electronic device can package the verification string in a designated location in the data packet, where the designated location is used to store the verification string to be verified by the data receiving end. Alternatively, the first electronic device can add the verification string to the form and then package the added form for transmission. This application embodiment does not limit the method used for packaging.

[0112] The method provided in this application embodiment converts, segments, and performs secondary conversion on wellbore data, and obtains a check string based on the converted array and MD5 algorithm. This allows the check string to be transmitted simultaneously with the wellbore data, enabling the data receiving end to verify the wellbore data based on the check string. This achieves data consistency verification, ensuring data consistency during transmission and guaranteeing data accuracy.

[0113] It should be noted that in the following embodiments, the names of the first array, the second array, and various parameters are the same as those used in the first electronic device in the above embodiments. This is only for the purpose of simplifying the terminology. For the second electronic device, the content of the form and the verification string it receives may change. That is, the received verification string may not be the string sent by the sending end, and the form may also change. Accordingly, the names of the first array, the second array, etc., are only used to represent the data obtained by the second electronic device after processing the received data, and are not necessarily the same as the data sent by the sending side.

[0114] Figure 3 This is a flowchart of a wellbore data consistency verification method provided in an embodiment of this disclosure. This method is applied to a second electronic device acting as a data receiver. See also... Figure 3 The consistency verification method for this wellbore data includes:

[0115] 301. Receive the form and verification string S from the first electronic device in the wellbore data acquisition system.

[0116] 302. Perform content conversion on the form to obtain a first array A, wherein the first array is the form represented by a character array.

[0117] 303. Divide the first array A into multiple data segments.

[0118] 304. Convert the multiple data fragments into Ulong type respectively to obtain the second array B.

[0119] 305. Obtain the first parameters SA1, SA2, SA3 and SA4.

[0120] 306. The first parameters SA1, SA2, SA3 and SA4 and the second array B are used as inputs to the MD5 checksum algorithm to obtain the second parameters SA1', SA2', SA3' and SA4'.

[0121] 307. Generate the verification string S' based on the second parameters SA1', SA2', SA3' and SA4'.

[0122] 308. Compare the verification strings S and S'.

[0123] 309. If the verification strings S and S' are consistent, the form verification passes.

[0124] In some embodiments, the step of performing content transformation on the form to obtain the first array A includes:

[0125] The first electronic device acquires the form content in the form, adds a first character to every two fields in the form content, and adds a second character between every two lines in the form content to obtain the first array A.

[0126] In some embodiments, dividing the first array A into multiple data segments includes:

[0127] Get the length of the first array A;

[0128] Divide the length by a constant 64 to obtain the number of blocks. Divide the first array A into multiple data segments according to the number of blocks.

[0129] In some embodiments, obtaining the first parameters SA1, SA2, SA3, and SA4 includes:

[0130] Get the hexadecimal variables S1, S2, S3, and S4;

[0131] Four hexadecimal constants are assigned to the hexadecimal variables S1, S2, S3, and S4 to obtain the first parameters SA1, SA2, SA3, and SA4.

[0132] Figure 4 This is a flowchart of a wellbore data consistency verification method provided in this embodiment of the disclosure. See also: Figure 4 The consistency verification method for this wellbore data includes:

[0133] 401. The second electronic device receives the form and verification string S from the first electronic device in the wellbore data acquisition system.

[0134] The second electronic device can parse the received data packet to obtain the form and the verification string S. For example, the second electronic device can extract the verification string from a specified position in the data packet, which is used to store the verification string to be verified by the data receiving end. As another example, the second electronic device can extract the verification string from the form. This application embodiment does not limit the method used for packaging.

[0135] 402. The second electronic device obtains the form content in the form, adds a first character to every two fields in the form content, and adds a second character between every two lines in the form content to obtain the first array A.

[0136] When the form is a two-dimensional form, each row of the form includes multiple fields. Therefore, "\t" can be added between every two fields, and "\r" and "\n" can be added between every two rows to separate the fields and the rows, thereby converting the two-dimensional form into a one-dimensional first array. Other symbols can also be used to separate fields and rows, and this application embodiment does not limit this.

[0137] 403. The second electronic device obtains the length of the first array A; divides the length by a constant 64 to obtain the number of blocks; and divides the first array A according to the number of blocks to obtain multiple data segments.

[0138] By dividing the length by a constant 64, the first array can be divided into multiple 64-bit data segments, ensuring that subsequent array transformations can be performed based on data segments of the same length. Of course, if the length of the first array exceeds the target length, when dividing based on the number of blocks, every 2N (where N is an integer greater than or equal to 1) 64-bit data segments can be divided into a single data fragment. That is, the division method can be adjusted according to the actual length of the first data segment, using 64 bits as the base fragment length, so that regardless of the division method, the number of data fragments obtained is the same, thus ensuring that the number of elements in the resulting second array is the same during subsequent processing.

[0139] 404. The second electronic device converts the multiple data fragments into Ulong type respectively to obtain the second array B.

[0140] Among them, Ulong (unsigned long integer) refers to storing characters as a 32-bit (4-byte) numerical form.

[0141] 405. The second electronic device acquires hexadecimal variables S1, S2, S3 and S4; sets four hexadecimal constants and assigns them to the hexadecimal variables S1, S2, S3 and S4 to obtain the first parameters SA1, SA2, SA3 and SA4.

[0142] Step 405 above describes the process by which the second electronic device acquires the first parameters SA1, SA2, SA3, and SA4. These four variables can be arbitrary, and this application does not impose any restrictions on them. The second electronic device can randomly generate four hexadecimal constants to assign values ​​to the above variables.

[0143] In some embodiments, the second electronic device can generate a corresponding hexadecimal constant based on the device information of the first electronic device that is stored in advance, such as device type and device identifier. This can ensure the legitimacy of the data sending device during verification at the data receiving end and prevent problems such as data tampering.

[0144] 406. The second electronic device uses the first parameters SA1, SA2, SA3 and SA4 and the second array B as inputs to the MD5 checksum algorithm to obtain the second parameters SA1', SA2', SA3' and SA4'.

[0145] After generating the first parameter, the second electronic device can input the generated first parameter and the second array B into the MD5 checksum generator. The generator uses the MD5 checksum algorithm to process the input data and obtain the second parameter.

[0146] In some embodiments, the second electronic device concatenates the first parameters SA1, SA2, SA3 and SA4 to the second array B to obtain the corresponding first intermediate parameters, and then inputs the concatenated first intermediate parameters into the MD5 checksum generator to obtain the corresponding second parameters SA1', SA2', SA3' and SA4'.

[0147] In some embodiments, the second electronic device splits the second array B into four data segments, concatenates each data segment with the first parameters SA1, SA2, SA3 and SA4 respectively to obtain the corresponding second intermediate parameters, and then inputs the multiple second intermediate parameters obtained by concatenation into the MD5 checksum generator to obtain the corresponding second parameters SA1', SA2', SA3' and SA4'.

[0148] The two processing methods described above are merely examples of generating the second parameter based on the first parameters SA1, SA2, SA3, and SA4 and the second array B. In other embodiments, the second parameter can also be generated based on the transformation of the second array and the multiple first parameters. This application does not limit this approach.

[0149] 407. The second electronic device generates a verification string S' based on the second parameters SA1', SA2', SA3' and SA4'.

[0150] In the embodiments of this application, the above-mentioned verification string can be generated by concatenating multiple second parameters. In some embodiments, the second electronic device can concatenate the above-mentioned multiple second parameters in a preset order, for example, concatenating them in ascending order of parameter number or in descending order of parameter number, which is not limited here.

[0151] Of course, in some embodiments, the verification string can also be obtained based on the string obtained by concatenating multiple second parameters. For example, the second electronic device extracts the first preset number of characters from the string obtained after concatenation as the verification string to increase the complexity of subsequent verification and thus improve data security.

[0152] 408. The second electronic device compares its own generated verification string S' with the received verification string S.

[0153] 409. If the second electronic device determines that the verification strings S and S' are consistent, then the form verification passes.

[0154] Furthermore, after confirming that the form has passed validation, the second electronic device stores the received form in the database.

[0155] 410. If the second electronic device determines that the verification strings S and S' are inconsistent, it returns a sending failure response to the first electronic device, which instructs the first electronic device to resend the form.

[0156] In some embodiments, if the second electronic device determines that the verification strings S and S' are inconsistent, it can also issue a warning to the management user to report potential data security risks.

[0157] On the second electronic device side, by adopting the same verification string generation method as on the first electronic device side, the MD5 data transmission verification algorithm can be used to compare the verification strings at the data receiving end, thereby achieving a comparison of the entire database.

[0158] The method provided in this application embodiment converts, segments, and performs secondary conversion on wellbore data, and obtains a check string based on the converted array and MD5 algorithm.
