The well site is typically located in a geographically remote area, and data is typically transmitted between the remotely located control platform using remote wireless transmission techniques, such as: GPRS, data radio, satellite communications, etc.
In the prior art, a remote communication network formed by using GPRS technology is used for communication connection between a control platform at a far end and a well site server at a well site. After the control platform issues the control instruction, the control instruction is transmitted to the well site server by using a remote communication network, and the well site server transmits the corresponding control instruction to corresponding well site equipment after processing.
However, the security of a long-distance communication network formed by long-distance wireless transmission technologies such as GPRS is poor, transmission data can be tampered by external maliciousness to form illegal information, and after the illegal information is transmitted to a wellsite server, the situation that the wellsite server controls wellsite equipment based on the illegal information occurs, that is, the reliability of the transmission data received by the wellsite server is low.

The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with reference to specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a drilling well site control system according to an embodiment of the present application. As shown in fig. 1, the well site control system comprises: the system comprises a control platform at a far end, a data transmission device at a drilling well site, a well site server and M well site devices; wherein M is an integer greater than or equal to 2. It should be noted that fig. 1 is only shown with 2 wellsite equipment.
The connection relation of the drilling well site control system is as follows:
the control platform is in communication connection with the data transmission device through a long-distance communication network. The long-distance communication network may be a communication network formed by long-distance transmission technologies such as a mobile communication network, a data transmission station, and satellite communication. The mobile communication network may be, for example, a network of any communication system, such as GPRS.
The well site server is respectively in communication connection with the data transmission device and each well site device. Such as a wired connection or a short-range wireless communication connection, the application is not limited herein. The short-range wireless communication connection may be, for example, bluetooth, wifi, zigbee, or the like.
The control platform may be, for example, a server or a cluster of servers. The control platform being located at the far end means that the control platform and the equipment located at the well site are not located in the same local area network, and communication can be realized through a long-distance communication network. For example, the control platform may be a server or a server cluster deployed in the cloud, or a server cluster located in an edge environment.
The data transmission device may be any device having a data transmission function and a data processing function.
The above-mentioned wellsite equipment may be, for example, equipment used in a wellsite to perform a drilling function, such as: lifting equipment, rotating equipment, power equipment, etc.
How to send the first information from the control platform to the wellsite server is described below.
The control platform is used for issuing first information to the data transmission device. The first information may carry control instructions for controlling the wellsite equipment, such as instructions to cause the valve 1 to close; or drilling data, such as well depth data, rate of drilling data, etc.; or may be a combination of drilling data and control instructions.
And the data transmission device is used for carrying out reliability verification on the first information and sending the first information to the well site server after the first information passes the reliability verification.
If the reliability verification of the first information fails, in one possible implementation manner, the data transmission device may discard the first information; in another possible implementation manner, the data transmission device may send feedback information of the first information reception failure to the control platform; in another possible implementation manner, the data transmission device may discard the first information and send feedback information of failure in receiving the first information to the control platform.
The above-described reliability verification may be, for example, one or more of the following: verification based on sender address, verification based on encryption scheme of information, and verification based on coding scheme of information. In particular what authentication method is used is related to the transmission configuration.
The verification based on the sender address may be, for example, verifying whether the address of the sender of the first information is the address of the control platform, if yes, the reliability verification is successful; if not, the reliability verification fails.
The verification of the encryption mode based on the information can decrypt the first information, for example, if the decryption is successful, the reliability verification is successful; if the decryption fails, the reliability verification fails. The decryption method should be a decryption method corresponding to the encryption method of the first information.
The verification of the information-based encoding scheme may be, for example, decoding the first information, and if the decoding is successful, verifying the reliability is successful; if the decoding fails, the reliability verification fails. The decoding method should be a decoding method corresponding to the encoding method of the first information.
It should be noted that, when the reliability verification is a combination of the at least two verification methods, if all the verification methods pass, the reliability verification is successful; if at least one verification mode fails, the reliability verification fails.
The reliability verification of the first information is carried out by using the data transmission device, illegal information such as maliciously tampered information can be eliminated, and the reliability of the data sent to the well site server is ensured.
After the first information passes the reliability verification, the first information may be directly sent to the wellsite server, or the first information may be processed and the processed first information may be sent to the wellsite server.
And the well site server is used for controlling the well site equipment according to the first information. In one possible implementation manner, the first information carries a control instruction for controlling the wellsite device, and the wellsite server may send the control instruction of the corresponding wellsite device to the wellsite device, so as to control the wellsite device. In another possible implementation manner, the first information includes drilling data, such as well depth data, and the wellsite server issues a control instruction to the wellsite device according to the first information, so as to control the wellsite device to reach the well depth.
The data transmission device performs reliability verification on the first information after receiving the first information issued by the control platform, and discards the first information if the reliability verification fails; and if the reliability verification is successful, the first information is sent to a well site server, and the well site server controls well site equipment according to the first information.
According to the drilling well site control system, the data transmission device located at the drilling well site is newly added on the basis of existing equipment (a control platform located at a far end and well site servers and M well site equipment located at the drilling well site), so that reliability verification is carried out on information issued to the well site servers by the control platform through the data transmission device. After verification is passed, the device will forward the information to the wellsite server. By the method, illegal information can be prevented from being sent to the wellsite server, so that the wellsite server controls the wellsite equipment based on the illegal information, and the reliability of the information sent to the wellsite server and the reliability of wellsite control are improved.
With reference to fig. 1, a description will be given below of how the above-described data transmission apparatus performs the reliability verification by decryption and decoding.
The control platform is specifically configured to send, to the data transmission device, first information that is encrypted by a first encryption method and encoded by a first encoding method.
The encryption processing performed by the first encryption method means that the first information is encrypted, and the first encryption method may be, for example, encryption performed by using a symmetric encryption technique, that is, the encryption processing and the decryption processing use the same key, for example, a data encryption standard (Data Encryption Standard, DES) algorithm, a symmetric packet encryption algorithm, or the like; asymmetric encryption techniques are also possible, i.e. encryption and decryption processes that use not the same key, e.g. RSA encryption algorithm, EIGamal and Diffie-Hellman duplex encryption algorithm; or may be a hash algorithm, not limited herein.
The first coding method refers to coding the first information, and the first coding method may be, for example, a coding method based on a Polar Code (Polar Code), a coding method based on a Turbo Code (Turbo Code), a coding method based on a Low-density Parity-check Code (LDPC Code), or a coding method in which a part of information adopts one of the coding methods and another part of information adopts the other coding method, which is not limited herein.
The first encryption mode and/or the first encoding mode may be a preset fixed mode, or may be adopted after the data transmission device negotiates with the control platform, or may be dynamically updated to the other by one of the two modes.
In particular, the first information may be encrypted first, and then the encrypted first information may be encoded. Alternatively, the first information may be encoded first, and then the encoded first information may be encrypted or the like.
The data transmission device is specifically configured to decrypt the first information using a decryption method corresponding to a first encryption method, and decode using a decoding method corresponding to a first encoding method; if decryption fails or decoding fails, determining that the reliability verification of the first information fails; and if the decryption is successful and the decoding is successful, determining that the reliability verification of the first information is passed.
The manner of decrypting and decoding the received first information by the data transmission device is reverse to the processing sequence of encrypting and encoding the first information by the control platform.
Regarding how to judge whether the decryption is successful, one possible implementation manner may preset a first feature value at the head or tail of the first information, and if the first feature value of the decrypted first information accords with the preset first feature value, the decryption is successful; if not, the decryption failure is indicated. In another possible implementation manner, the first information carries a digital signature, and if the digital signature obtained after decryption is consistent with the digital signature obtained by calculation, the success of decryption is indicated; if not, the decryption failure is indicated.
It should be noted that the decryption process may determine the integrity of the first information, and if the first information changes, the first information cannot be decrypted by using a preset decryption method, that is, the decryption fails. For example, the first information carries a digital signature, the digital signature is generated based on the content of the first information, if the content of the first information changes, the calculated digital signature also changes, the decrypted digital signature is generated based on the first information before the first information does not change, the decrypted digital signature is inconsistent with the calculated digital signature, which indicates that the integrity of the first information changes, and the decryption fails.
Regarding how to determine whether the decoding is successful, for example, a second feature value may be preset at the head or tail of the first information, and if the second feature value of the first information after decoding meets the preset second feature value, the decoding is successful.
According to the drilling well site control system, decryption and decoding reliability verification can be performed by using the data transmission device, when decryption is successful and decoding is successful, the reliability verification of the first information is determined to pass, so that the received first information is the information from the control platform and is not modified maliciously by the outside, namely, the first information is reliable, and the reliability of the information sent to a well site server is improved.
With continued reference to fig. 1, measures taken after the passing of the reliability verification will be described below.
After the first information is verified, the data transmission device is specifically configured to split the first information to obtain at least one type of sub-information if it is determined that the first information includes at least one type of sub-information.
The first information includes at least one type of sub-information, which means that control class sub-information and data class sub-information may be included. As previously mentioned, the control class sub-information may be a control command and the data class sub-information may be drilling data.
In one possible implementation manner, each type of sub-information in the first information adopts a different coding manner, for example, the control type sub-information adopts a coding manner based on Polar codes, and the data type sub-information adopts a coding manner based on Turbo codes. And presetting identification codes at the starting positions of each coding mode, and obtaining the number of the identification codes to determine whether the first information comprises at least one type of sub-information. If the first information at least comprises one type of sub-information, splitting the first information at the position of the identification code to obtain at least one type of sub-information.
And the sub information of each type in the first information is separately encoded, so that the information transmission efficiency can be improved, and the accumulation of redundant data can be avoided. For example, when the data code rate of the Turbo code is higher, the occupied channel of the Turbo code is not increased proportionally, but is slowly increased, and the Turbo code has excellent high-code rate data transmission advantage. The Polar code has high coding efficiency when the code rate is low, and the coding efficiency is reduced when the code rate is increased to a certain degree. Therefore, the transmission rate of the information can be effectively improved by encoding respectively.
In another possible implementation manner, the first information is generated using a fixed-length field, where the fixed-length field includes: the system comprises a first field and a second field, wherein the first field is used for filling control class sub-information, and the second field is used for filling data class sub-information. If a certain type of sub-information does not need to be issued at this time, a preset value, for example, 0, may be filled in a field corresponding to the first information. And acquiring the first length information and the second length information in the first information, and respectively judging whether the included information is a preset value or not, so as to determine whether the first information comprises at least one type of sub information or not. If the first information at least includes one type of sub-information, splitting the first information according to the first length and the second length to obtain at least one type of sub-information.
And after obtaining at least one type of sub-information by the method, sending the at least one type of sub-information to the well site server.
As mentioned above, the at least one type of sub-information may be control sub-information and data sub-information, which are divided according to data usage, the first information is split according to data usage, the split sub-information is sent to the wellsite server, and the wellsite server may directly process according to a corresponding processing flow without identifying various sub-information, so that the processing flow of the wellsite server is saved, and the processing efficiency of the wellsite server is improved.
According to the drilling well site control system, the data transmission device can split the first information after the reliability verification is successful, obtain the sub-information of different types, send the sub-information of various types to the well site server, and improve the processing efficiency of the well site server.
With continued reference to fig. 1, the first information may be generated autonomously by the control platform, or may be generated based on information reported by the wellsite server. The following description will take the first information as an example of the generation of the second information based on the report from the wellsite server.
The well site server is further configured to report second information to the data transmission device. The second information may be data for each wellsite equipment acquired by the wellsite server and/or drilling data.
The data transmission device is further configured to perform a second encryption process using a second encryption method and transmit the second encrypted data to the control platform after performing an encoding process using the second encoding method.
The second encryption mode and/or the second encoding mode may be a preset fixed mode, or may be adopted after the data transmission device negotiates with the control platform, or may be dynamically updated to the other by one of the two modes.
In one possible implementation, the encryption scheme adopted by the first encryption scheme and the encryption scheme adopted by the second encryption scheme are the same or different, and the encryption scheme adopted by the first encryption scheme and the encryption scheme adopted by the second encryption scheme are the same or different. For example, as shown in table 1 below:
TABLE 1
| First encryption mode | Second encryption mode | First coding mode | Second encoding mode |
| Encryption scheme 1 | Encryption scheme 1 | Coding scheme 1 | Coding scheme 1 |
| Encryption scheme 1 | Encryption scheme 2 | Coding scheme 1 | Coding scheme 1 |
| Encryption scheme 1 | Encryption scheme 2 | Coding scheme 1 | Coding mode 2 |
| Encryption scheme 1 | Encryption scheme 1 | Coding scheme 1 | Coding mode 2 |
The control platform is specifically configured to decrypt the second information using a decryption method corresponding to the second encryption method, and decode using a decoding method corresponding to the second encoding method, and generate the first information according to the second information after decryption is successful and decoding is successful.
How to determine whether decryption and decoding are successful is similar to the previous embodiment, and will not be described again.
The generation of the first information based on the second information means that the control platform generates the first information after processing the second information sent by the wellsite server. Illustratively, the second information includes drilling data, such as well depth data, and the control platform determines that drilling may be stopped based on the second information, and generates the first information including control instructions for instructing the wellsite equipment to stop drilling.
The drilling well site control system may send the first information to a data transmission device according to the description of the foregoing embodiment, and then send the first information to a well site server, so as to control well site equipment.
According to the drilling well site control system, the well site server, the data transmission device and the control platform are utilized for data transmission interaction, and control over well site equipment can be achieved.
