[0022] To further clarify the objectives, technical solutions, and advantages of the present invention, various embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, those skilled in the art will appreciate that numerous technical details are provided in various embodiments of the present invention to facilitate a better understanding of the present invention. However, even without these technical details and the various variations and modifications based on the following embodiments, the technical solutions claimed in the present invention can be achieved.

[0023] To facilitate understanding of the embodiments of the present application, relevant content about the mud logging data acquisition system is first introduced here.

[0024] With the development of science and technology, drilling technology has become one of the important means of energy extraction. In the drilling process, mud logging technology plays a key role. It can monitor and record various parameters and data of the drilling process in real time, so as to discover and solve problems in time and ensure the safety and efficiency of drilling.

[0025] In some technologies, logging systems typically use a centralized architecture, storing data on wellsite servers. This not only presents the risk of a single point of failure, but also makes it difficult to guarantee data security and integrity. First, this architecture relies too heavily on centralization. Once problems arise in key units (such as data storage, data services, and network services), data loss or service interruptions may occur. Second, while existing encryption technologies can ensure data security, they cannot guarantee data transparency. In other words, data owners cannot be sure whether the data has been tampered with or by whom. Finally, while existing permission control mechanisms can improve data security, they cannot prevent malicious operations by insiders. For example, authorized users may cause data damage or leakage due to misoperation or malicious operations.

[0026] However, existing data storage has the risk of single point failure, and the security and integrity of data are difficult to guarantee.

[0027] Example 1:

[0028] The embodiment of the utility model relates to a well logging data acquisition system.

[0029] Compared with the existing technology, the implementation method of the present invention adopts blockchain technology to encrypt the logging data to ensure that the data cannot be tampered with and is transparent; adopts a decentralized network design, and in the event of a network interruption, each data acquisition node 3 can independently store data to ensure that the data will not be lost; adopts a permission authorization mechanism, and only authorized users can access and modify the data, thereby improving the security of the data; thus, it solves the risk of single point failure in existing data storage and the problem that the security and integrity of the data are difficult to guarantee.

[0030] The following is a detailed description of the implementation details of the mud logging data acquisition system of this embodiment. The following content is only provided for ease of understanding and is not necessary for implementing this solution.

[0031] Reference Figure 1 The embodiment of the present utility model provides a mud logging data acquisition system, comprising:

[0032] At least one data collection node 3;

[0033] A blockchain module 2 connected to the data acquisition node 3, wherein the blockchain module 2 is provided with a plurality of sub-nodes, each sub-node corresponding to the data acquisition node 3, and used to store the logging data collected by the data acquisition node 3;

[0034] And a data acquisition module 1 connected to the blockchain module 2, the data acquisition module 1 is used to obtain logging data from the data acquisition node 3 through the blockchain module 2.

[0035] Specifically, the number of data acquisition nodes 3 can be one or more. Data acquisition nodes 3 are located near the edge of the wellsite network and are used to collect mud logging data, node attribute information, and package the data into a transaction format. In some examples, data acquisition nodes 3 have data storage capabilities, storing processed data locally for subsequent query and analysis. Multiple data acquisition nodes 3 are independent of each other. In some embodiments, data acquisition nodes 3 include at least one of a data acquisition instrument, a data transmission device, and a sensor. Mud logging data is collected using the data acquisition instrument, data transmission device, sensor, etc., or using sensors, detection equipment, or other devices with data acquisition capabilities.

[0036] In this embodiment, the blockchain module 2 is connected to each data collection node 3. The blockchain module 2 is constructed based on blockchain technology. Multiple sub-nodes are set in the blockchain module 2. When the logging data is sent to the blockchain module 2, the logging data collected by the data collection node 3 is stored in the sub-nodes in the blockchain module 2, realizing decentralized and secure real-time monitoring, effectively solving problems such as network disconnection, data security, and data integrity. In addition, a decentralized network design is adopted. In the event of a network interruption, each data collection node 3 can independently collect and store data to ensure that the logging data will not be lost.

[0037] In this embodiment, the data acquisition module 1 is connected to the blockchain module 2. When it is necessary to read the logging data, the data acquisition module 1 obtains the logging data collected by the data acquisition node 3 through the blockchain module to process the logging data and generate logging results to achieve decentralized and secure real-time monitoring, effectively solving problems such as network disconnection, data security, and data integrity.

[0038] In this embodiment, mud logging data is collected by data collection nodes 3 and stored by subnodes within blockchain module 2. When the mud logging data needs to be read, data collection module 1 reads the data collected by data collection nodes 3 through blockchain module 2. This achieves decentralized data monitoring. In the event of a network interruption, each data collection node 3 can independently collect and store data to ensure that the mud logging data is not lost, effectively improving the security and integrity of the mud logging data.

[0039] In some embodiments, the blockchain module 2 includes a verification unit, which is connected to the data acquisition node 3 and is used to verify the identity of the data acquisition node 3 and the validity of the collected logging data.

[0040] Specifically, the verification unit is connected to the data acquisition node 3 and is constructed using a smart contract, which can be understood as program code deployed on the blockchain network. The verification unit verifies the identity of the data acquisition node 3 and the validity of the logging data. When the data acquisition node 3 transmits the logging data, the verification unit verifies the identity of the data acquisition node 3 and verifies the validity of the logging data during the transmission process.

[0041] In some embodiments, the verification unit is further connected to the data acquisition module 1 , and is further configured to record the storage location of the logging data, so that the data acquisition module 1 acquires the logging data based on the storage location of the logging data.

[0042] Specifically, the verification unit is also connected to the data acquisition module 1 so that when the data acquisition module 1 obtains the logging data collected by the data acquisition node 3 through the block connection module, the logging data is obtained through the storage location of the logging data recorded by the verification unit.

[0043] In some embodiments, the data acquisition module 1 is provided with a configuration interface, and the configuration interface is used to set the data acquisition node 3 corresponding to the logging data acquired by the data acquisition module 1 .

[0044] Specifically, the data acquisition module 1 is provided with a configuration interface, which can also be called a system configuration interface. The data acquisition node 3 corresponding to the logging data obtained by the data acquisition module 1 can be set through the configuration interface. In other words, the user can determine which data acquisition nodes 3 form a collection group for logging data in the same area.

[0045] In some embodiments, the data collection node 3 is provided with a collection management unit, which is used to collect mud logging data and analyze the collected mud logging data.

[0046] Specifically, the acquisition management unit includes acquisition management software with functions such as data acquisition, data processing, data storage, self-diagnosis, breakpoint resumption, and automatic networking. It can detect or determine the health status and production conditions of wellsite equipment, and promptly issue alarms or take measures. In this embodiment, the acquisition management unit collects and analyzes mud logging data.

[0047] In some embodiments, the blockchain module 2 includes an encryption unit, which is used to encrypt the logging data transmitted by the data acquisition node 3.

[0048] Specifically, to ensure data security and modification traceability, each logging data stored in the blockchain module 2 is encrypted by an encryption unit. In some examples, the encryption unit uses the SHA algorithm to digitally sign the logging data.

[0049] In some embodiments, the encryption unit is further connected to the data acquisition module 1 , and the encryption unit is further used to transmit verification information to the data acquisition module 1 .

[0050] Specifically, the encryption unit is also connected to the data acquisition module 1. When the data acquisition module 1 accesses the logging data stored in the blockchain module 2, verification is required to ensure the security of the accessed data. Therefore, after the logging data is encrypted, the verification information is transmitted to the data acquisition module 1 via the encryption unit. In some examples, the encryption unit uses the SHA algorithm to digitally sign the logging data. In addition to basic integrity verification information, the signature information also includes information such as the data's creation time, modification time, deletion time, user identity, data source, and transmission path. By retrieving the digital signature, a complete overview of the information access and storage can be obtained, ensuring the traceability and security of data modifications.

[0051] In some embodiments, it also includes: a rights management module, which is connected to the data acquisition module 1, and the rights management module is used to authorize the access user to access the logging data stored in the blockchain module 2.

[0052] Specifically, the permissions management module limits the scope of users who can access mud logging data, thereby improving data access security. In some cases, the permissions management module manages and authorizes users, restricting user behavior so that only authorized users can access and modify data, thereby improving system security.

[0053] Example 2

[0054] The implementation method of the present utility model is a detailed description of the above embodiment 1, see Figure 2 The mud logging data collection system includes: data collection module 1, blockchain module 2, smart contracts, and numerous data collection nodes 3 (also known as edge mud logging data collection nodes). The specific implementation steps are as follows:

[0055] Step 1: Develop a data collection module based on blockchain technology1.

[0056] Data acquisition module 1 is a server with high computing power and large storage space. The server is installed with software such as an operating system, a blockchain client, and a database for collecting and storing logging data. The server can access blockchain module 2 through the blockchain client software.

[0057] The data acquisition module 1 can be connected to the blockchain module 2 and obtain the logging data from the data acquisition node 3 through the blockchain module 2;

[0058] The data acquisition node 3 has the function of collecting and storing logging data, and can independently complete the data collection and storage functions when the network is interrupted to avoid data loss;

[0059] Multiple sets of data collection nodes 3 can be deployed in the blockchain module 2 and can provide data sharing services to authorized users;

[0060] The data acquisition module 1 has multiple modules such as data acquisition, data storage, data service, user management, node management, and system log, and can interact with other data acquisition modules 1 through the blockchain module 2;

[0061] The user can decide which data acquisition nodes 3 form a set of data acquisition modules 1 through settings;

[0062] The data acquisition module 1 can manage the node modules and set which data acquisition nodes 3 the system consists of.

[0063] Step 2: Design blockchain module 2

[0064] According to the actual business needs, build a public blockchain (Public Blockchain), a consortium blockchain (Consortium Blockchain or Federated Blockchain) or a private blockchain (Private Blockchain). The main process is as follows:

[0065] First, prepare the operating system and hardware. Rationally configure hardware resources such as CPU, memory, and network bandwidth based on business needs to ensure that hardware such as servers, virtual machines, and terminal devices meet the requirements of the blockchain software.

[0066] Next, download and install the blockchain network dependent software. Download and install the necessary software for encryption, decryption, key generation, certificate generation, and console operations for various blockchain technologies.

[0067] Finally, start and maintain Blockchain Module 2. Specify the IP address and port number, download and configure the console, optimize network load and performance, and perform security checks and reinforcement on Blockchain Module 2.

[0068] The blockchain module 2 consists of multiple nodes, each of which stores complete or partial data of the blockchain.

[0069] Blockchain module 2 encrypts data through blockchain technology to ensure data immutability and transparency, thereby protecting the integrity and reliability of the data.

[0070] Blockchain module 2 can expand the system through blockchain technology and increase the number of nodes in blockchain module 2.

[0071] Blockchain module 2 is used to store and manage logging data to ensure the security and credibility of the data.

[0072] Step 3: Design a verification unit suitable for the data acquisition module 1.

[0073] The verification unit is constructed through smart contracts, which include: code writing, code compilation and testing, and blockchain deployment of the code.

[0074] After the smart contract design is completed, its bytecode and related information will be stored on each node participating in the blockchain module 2.

[0075] The operation of smart contracts is based on preset codes. When the conditions in the contract are met, the code will automatically perform the corresponding operations.

[0076] Smart contracts do not require a centralized authority to arbitrate the execution of the contract. The supervision and arbitration of the contract are completed by computer programs, ensuring the traceability and irreversibility of transaction records.

[0077] Smart contracts are deployed on the blockchain, and their content is open and transparent. All participants can view the content and execution process of the contract, thereby increasing trust and transparency.

[0078] Smart contracts are jointly maintained by network nodes, so they can run permanently and are not controlled by a single organization or server.

[0079] The execution of smart contracts is based on code rather than human trust, so transactions and cooperation can be carried out safely in an untrusted environment.

[0080] The execution of smart contracts does not require third-party intervention and can respond to user requests at any time and place, greatly improving efficiency and saving time and costs.

[0081] The execution of smart contracts is based on blockchain technology, and the content of the contract cannot be tampered with or modified, ensuring the reliability and security of the contract.

[0082] Step 4: Design and develop data collection nodes 3 based on blockchain technology.

[0083] Data acquisition node 3 refers to the business platform built near the edge of the well site network, which is mainly used to complete the collection, storage, calculation, and service functions of logging data;

[0084] Data collection node 3 is closer to the data source, which can reduce data transmission delay and bandwidth consumption;

[0085] The data acquisition node 3 has computing capabilities and can process and analyze data locally, reducing dependence on the central server and improving data processing efficiency;

[0086] The data acquisition node 3 exchanges data with external devices through various communication protocols (such as RS485, RS232, ModBus, CAN, etc.);

[0087] The data acquired by the data acquisition node 3 can be generated in real time or uploaded regularly, including sensor data of the well site, geological data, daily engineering reports, etc.

[0088] The data collection node 3 has a data storage function and can store the processed data locally for subsequent query and analysis;

[0089] The data processed by the data collection node 3 can be transmitted to the data collection module 1 or other nodes in the blockchain module 2 for further processing as needed;

[0090] The data acquisition node 3 is equipped with collection management software designed specifically for the data acquisition node 3. It has functions such as data collection, data processing, data storage, self-diagnosis, breakpoint resumption, and automatic networking. It can detect or judge the health status and production conditions of well site equipment, and issue alarms or take measures in a timely manner.

[0091] The data acquisition nodes 3 include but are not limited to intelligent instruments, intelligent meters, intelligent transmission equipment, intelligent sensors, etc. located at the well site.

[0092] The data acquisition nodes 3 are all independent and can complete certain functions independently.

[0093] One or more data acquisition nodes 3 can be deployed at the well site as needed.

[0094] Step 5: Data encryption

[0095] In order to ensure data security and modification traceability, the SHA algorithm is used to digitally sign each data object flowing within the network. In addition to basic integrity verification information, the signature information also includes data creation time, modification time, deletion time, user identity, data source, transmission path and other information. By retrieving the digital signature, a complete information access and storage panorama can be obtained, ensuring the traceability and security of data modifications.

[0096] Step 6: User permission authorization

[0097] Through the user management module, users are managed and authorized, and user behavior is restricted. Only authorized users can access and modify data, thereby improving the security of the system.

[0098] Through the above steps, a mud logging system based on blockchain technology is constructed. The system can be easily deployed on the blockchain network without geographical restrictions. It can also monitor and manage the construction of numerous well sites. The system has the advantages of decentralization, security, and real-time monitoring. It can effectively solve problems such as network disconnection, data security, and data integrity.

[0099] In this embodiment, a decentralized logging system is implemented to avoid the risk of single point failure and ensure the security and integrity of data; blockchain technology is used to encrypt data to ensure that the data cannot be tampered with and transparency, thereby improving the credibility of the data; through distributed storage, each edge intelligent node has functions such as self-diagnosis, breakpoint resumption, and automatic networking, thereby realizing independent protection of data; through the permission authorization mechanism, only authorized users can access and modify data, effectively preventing malicious operations by internal personnel and improving data security.

[0100] In this embodiment, the blockchain-based mud logging system and method can achieve decentralized real-time data collection and monitoring. Data encryption through blockchain technology ensures data immutability and transparency. The use of a permission authorization mechanism effectively prevents data loss and malicious operations, improving data security and reliability. This has important practical value for data security protection and oil exploration and development. It has promising application prospects in oil exploration and development, mud logging data collection, and other application fields.
