[0024] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be described clearly and in detail below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in the field based on the embodiments in the embodiments of the present invention should fall within the scope of protection of the embodiments of the present invention.

[0025] Figure 1 A schematic diagram of a method for managing the integrity of oil and gas well pipes and rods based on a two-dimensional code and Internet of Things technology is provided in an embodiment of the present invention. Figure 1 As shown, this embodiment mainly includes:

[0026] S101. Fixing a QR code location plate made of wear-resistant and corrosion-resistant material at a preset position on the surface of an oil and gas well pipe.

[0027] For example, when selecting the location of the QR code to be etched on the well pipe, the use environment and operation requirements of the well pipe need to be considered. According to the structural characteristics and installation location of the well pipe, a location that is easy to scan and identify is selected to ensure the effectiveness and stability of the QR code.

[0028] Specifically, the structural characteristics of the well pipe include material, shape, size and other aspects, which will directly affect the etching method and location selection of the QR code. For example, if the surface of the well pipe is rough or uneven, it will be more convenient to etch the QR code in a flat area. In addition, the shape and size of the well pipe will also affect the size and placement of the QR code, which requires reasonable design and layout according to the actual situation.

[0029] The installation location of the well pipe is usually divided into two situations: underground burial and ground erection, which will have different effects on the selection of the QR code etching location. In the case of underground burial, considering environmental factors and usage requirements, the QR code may need to be etched on the well pipe cover or side position to facilitate scanning by construction personnel or maintenance personnel. In the case of ground erection, the QR code can be etched directly on the surface of the well pipe, but care must be taken to avoid damage and contamination by external objects.

[0030] It should be understood that in order to ensure the effectiveness and stability of the QR code on the well pipe, the structural characteristics and installation location of the well pipe should be comprehensively considered when selecting the etching location, and avoid choosing areas that are susceptible to damage or contamination. At the same time, waterproof and wear-resistant etching materials can be used, combined with appropriate light and angle settings to improve the scanning and recognition rate of the QR code. Figure 3 As shown, the two-dimensional code 10 can be etched in the center of the two-dimensional code position sign 9 located in the middle of the oil and gas well pipe 11.

[0031] S102, using laser etching technology to laser engrave a two-dimensional code label containing information recognition function on the surface of the two-dimensional code location sign.

[0032] Exemplarily, the etching work first uses electromagnetic pulse cold-pressed micro-welding to fix a QR code location plate made of wear-resistant and corrosion-resistant metal material at a specific position on the surface of the oil and gas well pipe; then, laser etching technology is used to laser-print a QR code label containing identifiable information on the surface of the location plate; finally, the fitting surface of the QR code is fixed to the surface of the oil and gas well pipe by producing slight plastic deformation, thereby producing a micro-connection with the surface of the oil and gas well pipe, but without any metallurgical reaction, tissue change, or damage to the well pipe body.

[0033] The electromagnetic pulse cold-pressed micro-welding method uses electromagnetic blasting pressure to shrink the diameter of the identification ring made of wear-resistant and corrosion-resistant metal materials evenly without wrinkles, so that the fitting surface undergoes slight plastic deformation and is fixed at a specific position on the well pipe surface, thereby producing a micro connection with the well pipe without damaging the well pipe body. Figure 4 As shown, it includes: a terminal 12; an upper fixing plate 13; a coil 14; Zylon 15; a magnetic collector 16; a magnetic collector support plate 17; a workpiece 18; a cushion block 19; a cushion block 20; and a lower fixing plate 21.

[0034] Preferably, according to the working characteristics of the well pipe, choose a suitable material to make the QR code. If the well pipe works in a high temperature environment, choose a high temperature resistant material, such as high temperature resistant stainless steel or high temperature resistant plastic; if the well pipe works in a corrosive environment, choose a corrosion resistant material, such as stainless steel, acid and alkali resistant plastic or coating material; considering the pressure on the well pipe, choose a material with sufficient strength and hardness, such as stainless steel or carbon steel; if the well pipe needs to withstand frequent wear, choose a wear resistant material, such as a ceramic coating material or a special alloy material.

[0035] It should be understood that the introduction of QR code technology as a core tool for the management of individual information of oil and gas well pipes enables rapid identification and query of individual well pipes by etching different QR codes on each well pipe. In this way, the management process of individual well pipe information can be greatly simplified and work efficiency can be improved. Taking into account the actual situation that some well pipes have curved structures, in order to meet the information management needs of different types of well pipes, the curved QR code technology is innovatively introduced, bringing a new breakthrough in the integrity management of oil and gas well pipes. For well pipes with curved structures, the traditional QR code etching process is difficult to ensure clear readability, so a special laser etching process is used. This process has been carefully developed and repeatedly debugged, and can be precisely adjusted according to the specific curvature and shape of the curved well pipe. During the etching process, the laser equipment accurately controls the etching depth, angle and intensity to ensure that the QR code pattern presents a clear black and white contrast on the curved surface, avoiding blurring or deformation due to surface irregularities. For example, for well pipe parts with larger curvatures, the laser etching parameters are optimized to make the QR code lines finer and the patterns more regular. At the same time, the material characteristics of the curved surface of the well pipe are considered, and the appropriate etching energy and frequency are selected to prevent damage to the well pipe surface or affect its performance.

[0036] S103: Establish an information management file, and enter relevant information of the well pipe into the information management file.

[0037] For example, as an important equipment for oil transportation, the information management of the well pipe is crucial. When entering the relevant information of the well pipe, it is necessary to ensure the integrity and accuracy of the information. The factory information, production date, material specifications, quality inspection report, use environment and other information of the well pipe can be recorded and integrated for storage, and a complete archive and data foundation for information management can be established to provide managers with convenient information query and analysis. The entered relevant information can help managers trace the manufacturing and transportation process of the well pipe, better monitor the status and operation of the well pipe, identify problems in time and take corresponding measures. During the use of the well pipe, timely updating the use environment and maintenance records of the well pipe can help extend the service life of the well pipe, and can also help managers formulate maintenance plans in time to ensure the safe and reliable operation of the equipment.

[0038] S104, binding the relevant information of the well pipe with the QR code label.

[0039] For example, in order to achieve comprehensive management and traceability of well pipe information, the entered well pipe information is bound to a QR code label. By attaching a QR code label to the well pipe, the relevant information of the well pipe can be scanned to achieve rapid retrieval and update of information. Using QR code scanning technology to realize intelligent management of well pipe information helps to improve management efficiency and accuracy. By scanning to obtain detailed information on the well pipe, manual entry errors and information omissions can be avoided, ensuring the integrity and accuracy of the information. Intelligent well pipe information management can help managers better monitor the use of well pipes, identify problems in a timely manner and take measures to improve the efficiency and quality of management work.

[0040] S105. In the manufacturing, transportation, use and maintenance of the oil and gas well pipe, relevant information of the oil and gas well pipe is obtained by scanning the QR code label on the oil and gas well pipe.

[0041] For example, in the manufacturing, transportation, use and maintenance of well pipes, workers can use their mobile phones to scan the QR code on the well pipes and obtain detailed information about the well pipes. The QR code label can be used as an entry point for well pipe information management. The scanned information includes the well pipe number, production information, installation location, maintenance records, etc., which helps to monitor and manage the use of the well pipes in real time. By scanning the QR code, important data of the well pipes can be quickly obtained, helping managers to fully understand the status and use of the well pipes.

[0042] By using QR code scanning technology to obtain well pipe information, real-time monitoring and management of well pipes can be achieved. Managers can use the information obtained by scanning to timely understand the location, usage status, maintenance records, etc. of the well pipes and make corresponding management decisions. Through real-time monitoring and management, the management efficiency and accuracy of well pipes can be improved to ensure the safe operation of equipment.

[0043] S106, uploading the relevant information of the oil and gas well pipe to the information management system to achieve unified management and storage of the well pipe information.

[0044] For example, the scanned information can be uploaded to the information management system APP to achieve unified management and storage of well information. By uploading well information to the information management system APP, managers can easily find detailed information on specific wells, make necessary modifications and records, trace the history and maintenance of wells, and provide support for management decisions. Managers can centrally manage well information through the information management system APP to ensure the integrity and accuracy of the information. Unified management and storage of well information helps improve management efficiency and decision-making quality, and provides reliable support for well operations.

[0045] The application of information management system APP in well pipe management is of great significance. Through the information management system APP, managers can obtain well pipe information anytime and anywhere, and conduct real-time management and decision-making. The information management system APP provides rich functions and convenient operation, providing managers with powerful tools to help them better monitor and manage the use of well pipes and improve the efficiency and quality of management work.

[0046] The oil and gas well pipe integrity management method based on two-dimensional code and Internet of Things technology of the present invention realizes the automatic entry and acquisition of well pipe information through two-dimensional code electronic tags, greatly improving the accuracy and reliability of information; adopts electronic management to realize real-time monitoring and tracing of well pipe information, simplifies the management process, and improves management efficiency; compared with traditional manual records and paper labels, it saves management manpower costs and the cost of using paper labels; comprehensively and effectively realizes the recording, tracing and management of well pipe information, and improves the efficiency and quality of oil and gas well pipe management.

[0047] In another implementation of the present invention, the two-dimensional code location sign is made of wear-resistant and corrosion-resistant metal materials, and the wear-resistant and corrosion-resistant metal materials include at least one of stainless steel, nickel alloy, copper alloy or titanium alloy.

[0048] Exemplarily, in order to meet the requirements of wear resistance and corrosion resistance, the metal material should be selected from at least one of stainless steel, nickel alloy, copper alloy and titanium alloy, and the engraving depth of the etched two-dimensional code should be 0.3-0.5 mm.

[0049] In another implementation of the present invention, the two-dimensional code label is designed based on the QR Code encoding algorithm, and the error correction code and mask are optimized; the composition of the two-dimensional code label includes: a blank area, a position detection pattern, a position detection pattern separator, a positioning pattern, a correction pattern, format information, version information, data and an error correction code word.

[0050] For example, a 2D barcode is a black and white graphic that records data symbol information in a certain geometric shape distributed in a two-dimensional direction according to a certain rule. In the coding, the concept of "0" and "1" bit streams that constitute the internal logic basis of the computer is used, and several geometric shapes corresponding to the binary system are used to represent information. The information is automatically read by an image input device or an optoelectronic scanning device to realize automatic information processing. For a limited etching area, a coding algorithm that can achieve high-density code in a small area needs to be selected.

[0051] like Figure 2 As shown, the composition of the QR code includes: blank area 1; position detection pattern 2; position detection pattern separator 3; positioning pattern 4; correction pattern 5; format information 6; version information 7; data and error correction code 8. This example uses QR Code encoding, and optimizes its error correction code and mask to reduce interference and errors in the QR code and improve the reliability and scanning recognition rate of the QR code. The encoded QR code is etched on the surface of the oil and gas well pipe. The size of each QR code is 1cm*1cm, and the code quantity is 50 characters. During the laser etching process, the printer needs to be placed horizontally and keep a certain distance to avoid etching errors. In addition, regular maintenance and inspection of the condition of the QR code, and timely replacement and repair of damaged QR codes are also important measures to ensure the effectiveness of information management.

[0052] Preferably, when designing the QR code, the curvature and shape of the surface are fully considered, and the encoding algorithm is deeply optimized. Different degrees of curved surfaces pose unique challenges to the layout and encoding methods of the QR code. Through mathematical modeling and simulation experiments, the influence of various surface parameters on the readability of the QR code is analyzed. According to different surface conditions, the module size, arrangement and error correction level of the QR code are adjusted to ensure stable storage and transmission of information on surfaces with different curvatures. For example, for relatively flat surfaces, the module size of the QR code is appropriately increased to increase the information storage capacity; for surfaces with larger curvatures, a more compact encoding method is used to reduce interference between modules. Through the optimized encoding algorithm, the curved QR code can adapt to various complex surface shapes, providing a solid guarantee for the accurate identification of well pipe information.

[0053] To further improve the scanning recognition rate of curved QR codes, the scanning equipment can use advanced optical technology and image recognition algorithms to accurately capture the QR code image on the curved surface, and quickly process and interpret it. The lens and sensor of the equipment are specially designed to adapt to different lighting conditions and curved surface angles, ensuring stable reading of QR code information in various working environments. At the same time, a matching software system is developed, which has powerful image preprocessing and error correction functions. During the scanning process, the software automatically corrects and enhances the image of the curved QR code, removes noise and interference, and improves the clarity and readability of the QR code. In addition, the software can also make intelligent adjustments according to different curved surface shapes and scanning angles, optimize the recognition algorithm, and ensure accurate and fast reading of the information in the QR code. Through the synergy of dedicated scanning equipment and software, the scanning and information extraction of the QR code on the curved surface can be completed instantly, greatly improving work efficiency and the accuracy of information management.

[0054] The single-piece information management of oil and gas well pipes based on QR codes has the following advantages: by pasting a QR code on each well pipe, each well pipe can be uniquely identified and managed in real time, which is convenient for recording and tracking the usage, maintenance records and other information of the well pipe; QR code technology can ensure the accuracy and consistency of well pipe information, avoid errors and loopholes that may exist in manual recording and management, and improve the reliability and credibility of data; the well pipe management method based on QR codes can realize the digital recording and storage of information, facilitate information sharing and collaboration between multiple departments or personnel, and improve management efficiency and communication effects; QR code technology can be combined with intelligent management systems to realize real-time monitoring, data analysis and early warning of well pipe status, improve the scientificity and accuracy of management decisions, and help to timely discover problems and take measures; through QR code technology, real-time tracking and recording of fault monitoring and processing of well pipe equipment can be realized, which helps to timely discover and handle faults and improve production efficiency and safety. In summary, the QR code-based single-piece information management of oil and gas well pipes has the advantages of real-time, accuracy, sharing, intelligence and timeliness. It can effectively improve the efficiency and quality of well pipe management and promote the integrity management of the oil and gas well pipe string itself.

[0055] In another implementation of the present invention, it also includes: when the QR code label on the oil and gas well pipe is scanned, a three-dimensional model of the oil and gas well pipe is presented on the device screen, the three-dimensional model shows the structure, size and position of each component of the well pipe, and displays the operating data of the oil and gas well pipe in real time.

[0056] For example, by combining augmented reality technology with QR codes, users can have a richer and more intuitive experience. When workers use mobile phones or special equipment to scan the QR code on the well pipe, the three-dimensional model of the well pipe can be immediately displayed on the device screen, clearly showing the structure, size and location of each component of the well pipe. At the same time, the operating status of the well pipe, such as temperature, pressure, flow and other data, can also be displayed in real time, allowing workers to quickly understand the current situation of the well pipe.

[0057] During maintenance and inspection, AR technology can provide virtual operation guides and prompts to guide workers to perform the correct operation steps. For example, when a part needs to be replaced, the AR screen can highlight the location of the part and provide animation demonstrations of disassembly and installation, greatly improving work efficiency and accuracy.

[0058] In the modern industrial field, the widespread use of handheld mobile devices has brought revolutionary changes to data management. By integrating the QR code scanning function, these devices significantly improve the efficiency of entering single well operation data and realize real-time and efficient data transmission. As the core link of data management, the transmission and storage of data is crucial to the entire system in terms of efficiency and security. With the help of advanced wireless transmission technology, the present invention can realize the real-time transmission of single well operation data to the control center to ensure the timeliness of the data. At the same time, through cloud computing technology, the present invention further optimizes the data management and sharing process, realizes the synchronous update and rapid sharing of data, thereby greatly improving the efficiency and accuracy of data management.

[0059] In the process of data transmission and storage, data security should also be highly valued. To this end, the present invention uses the industry-leading AES encryption algorithm to encrypt the transmitted data, effectively preventing the data from being illegally intercepted or tampered with during the transmission process. In addition, the present invention also establishes a secure communication channel through the HTTPS protocol to ensure the security and reliability of the data transmission process. At the same time, the present invention strictly abides by data protection laws and regulations including GDPR, ensures that relevant regulatory requirements are followed during data processing and storage, and protects the privacy and data security of users. The present invention is committed to providing users with a safe and compliant data management environment, allowing users to use the services of the present invention with confidence and enjoy an efficient and secure data management experience.

[0060] In another implementation of the present invention, the relevant information of the oil and gas well pipe includes manufacturing information, transportation information, usage information and maintenance information.

[0061] In another implementation of the present invention, it also includes: installing sensors and data acquisition equipment on the oil and gas well pipe to collect the working status and usage of the oil and gas well pipe in real time, the sensors including pressure sensors, temperature sensors and flow sensors; and sending the working status and usage to the information management system in real time through wireless transmission technology.

[0062] For example, according to the work requirements, select a suitable sensor type, common sensor types include pressure sensors, temperature sensors, flow sensors, etc. When selecting a sensor, it is necessary to pay attention to the sensor's measurement range, accuracy, resolution, response time and other technical parameters to ensure that the sensor can meet the application requirements.

[0063] Consider the environment and installation method: Consider the use environment of the sensor, such as temperature, humidity, pressure and other conditions, select sensors that can adapt to these environmental conditions, and consider its installation method, such as fixed type, plug-in type, etc. The installation method should ensure that the sensor can work stably and obtain data accurately. Under the premise of meeting the functional and performance requirements, consider the cost of the sensor. The prices of sensors of different brands and models may vary, and it is necessary to make a reasonable choice based on the budget.

[0064] Furthermore, 5G technology has broad application prospects in oil and gas well pipe information management with its advantages of large bandwidth, wide coverage, low latency, and low power consumption. Through the 5G network, the data of oil and gas well pipes can be transmitted to the control center or cloud platform in real time to realize timely sharing and processing of data. Based on the high bandwidth and low latency characteristics of the 5G network, remote monitoring and control of oil and gas well pipes can be realized to improve management efficiency and safety. Using the large amount of data transmitted by the 5G network, in-depth data analysis can be carried out to discover potential problems and put forward optimization suggestions, providing strong support for the production and management of oil and gas well pipes.

[0065] Wireless communication can realize the real-time transmission of oil and gas well pipe data and improve the efficiency and reliability of data transmission. Common wireless communication methods include Wi-Fi, Bluetooth, LoRa, etc. Through the wireless communication network, remote monitoring of oil and gas well pipes can be realized, including video monitoring, status monitoring, etc. This helps to discover and deal with potential problems in a timely manner and improve management efficiency. Wireless communication can realize communication between various devices in oil and gas well pipes, including sensors, controllers, actuators, etc., which helps to achieve collaborative work and intelligent management of equipment.

[0066] In another implementation of the present invention, it also includes: the information management system remotely controls the oil and gas well pipe according to the working status and usage, adjusts working parameters, and starts or stops equipment.

[0067] For example, Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown in the figure, a cloud database is established in the information management system to centrally store all relevant data of a single oil and gas well pipe. This database should contain basic information of the well pipe (such as model, specification, material, etc.), usage records, maintenance records, location information, etc. Cloud computing technology can ensure the safe storage and efficient access of data. Sensors and other data acquisition equipment are installed on a single oil and gas well pipe to collect real-time information such as the working status and usage of the well pipe. These data can be sent to the cloud database in real time for storage and processing through wireless transmission technology (such as 4G / 5G network or Internet of Things technology).

[0068] Managers can access the cloud database through mobile devices or computers anytime and anywhere to view the real-time and historical data of the well pipes, understand the working status and usage of the well pipes, and at the same time, remotely control the well pipes, such as adjusting working parameters, starting or stopping equipment, etc.

[0069] In another implementation of the present invention, the information management system includes query, modification, tracing, data analysis and status prediction functions.

[0070] For example, the information management system can provide functions such as query, modification, and tracing to help managers understand the status and usage of well pipes in a timely manner and make reasonable decisions and plans.

[0071] The powerful computing power of the cloud computing platform is used to analyze and process the collected data. Through data analysis, the use, performance status, potential problems, etc. of the well pipe can be understood, and corresponding optimization measures can be formulated accordingly. For example, the service life of the well pipe can be predicted based on its usage record, and maintenance plans can be reasonably arranged to reduce downtime and improve production efficiency. Through the cloud computing platform, remote monitoring and management of a single oil and gas well pipe can be achieved. Based on the data analysis capabilities of the cloud computing platform, intelligent early warning and fault diagnosis functions can be realized. Through real-time monitoring and analysis of data, abnormal conditions in the operation of the well pipe can be discovered in time, and early warning information can be automatically issued. At the same time, the intelligent algorithm of the cloud computing platform can be used to diagnose faults and provide maintenance suggestions or solutions.

[0072] When using cloud computing technology to manage individual pipes in oil and gas wells, it is necessary to attach great importance to information security and compliance assurance. Advanced encryption technology and security protocols (such as AES encryption algorithm and HTTPS protocol) should be used to ensure the security of data transmission and storage. At the same time, relevant data protection regulations (such as GDPR) should be followed to ensure compliance with data processing.

[0073] It should be understood that the information management system based on QR codes integrates scanners and information databases to realize the scanning of QR codes and the storage and query of single-root information of well pipes. With this system, operators can obtain complete information of the well pipe, including production date, material, diameter, etc., by simply scanning the QR code on the well pipe. At the same time, the system can also record and track the maintenance and replacement of well pipes through the instant update function of the QR code, and provide comprehensive management support. In addition, cloud computing technology has been introduced in the information management system. By storing the single-root information of the well pipe in the cloud, it can be shared and accessed by multiple departments and multiple locations, which will greatly improve the collaborative efficiency of various links within the oil and gas enterprises. Finally, the management and protection of QR codes will be strengthened, and the uniqueness and reliability of QR codes will be ensured through packaging, anti-counterfeiting technology and other means. At the same time, in order to prevent the QR code from being damaged due to long-term use, a plan for regular replacement of QR codes is also formulated to ensure the stable operation of the system.

[0074] In summary, the design macro-ideas of the oil and gas well pipe single root information management method based on QR code mainly include the introduction of QR code technology, the design of information management system, the application of cloud computing technology, and the strengthening of QR code management and protection. By adopting the above method, the comprehensive management and traceability of oil and gas well pipe single root information can be achieved, and the management efficiency and quality can be improved.
