Description

A communication system and method for fracturing equipment

[0001] This disclosure claims priority to the patent application filed on March 28, 2025, with China National Intellectual Property Administration, application number 202510386325.6, entitled "A Communication System and Method for a Fracturing Equipment Set". Technical Field

[0002] This disclosure relates to the field of communication technology for oil and gas extraction equipment, specifically to a communication system and method for a complete set of fracturing equipment. Background Technology

[0003] Oil and gas field fracturing operations are complex systems engineering projects. The entire system includes fracturing equipment, sand mixing equipment, instrumentation equipment, blending equipment, and chemical additives equipment. Throughout the operation, the core of control and monitoring is at the instrumentation equipment end. Command and supervision personnel use the instrumentation equipment to provide real-time command and supervision of the entire fracturing operation, while all equipment operating data and equipment status are transmitted and monitored via an industrial Ethernet network built on-site.

[0004] Currently, the mainstream communication methods between fracturing equipment are industrial communication cables, i.e., wired communication, and ring redundant networks. This ensures communication stability even with only one breakpoint in the network. However, when two or more breakpoints occur, equipment located at the breakpoints and far from the control center will be unable to communicate normally with the control center.

[0005] Currently, some work sites are also experimenting with using wireless transmission for control. Wireless transmission can reduce the amount of wiring work and the impact of cable damage on operations. However, the current wireless control method suffers from slightly poor signal stability. If wireless and wired networks are connected simultaneously, it can cause a network storm, directly leading to network paralysis.

[0006] In fracturing operations, fracturing equipment may be used in flexible team formations. Well sites may have multiple fracturing equipment of different brands and configurations operating in combination. If the network is not handled properly, network conflicts or storms may occur, directly affecting the use of the entire fracturing unit. Summary of the Invention

[0007] This disclosure aims to at least address the technical problems in the prior art where network storms and network conflicts exist when fracturing equipment is networked, affecting normal communication during operation.

[0019] The switching unit is further configured to switch the communication mode between the instrument and the work equipment to wireless communication mode when the number of packet losses in the wired network is greater than a second quantity threshold and the wireless communication strength of the wireless network is greater than a second preset strength threshold.

[0020] In some embodiments, the detection unit is further configured to detect a wired disconnection fault between the instrument and the working equipment;

[0021] The control module is also used to control the operating equipment to perform normal operation when the number of wired disconnection faults is less than a preset threshold number of disconnections.

[0022] In some embodiments, the operating equipment further includes at least one of a sand mixing device, a blending device, and a chemical additive device, and the instrumentation device is connected in series with at least one of the sand mixing device, the blending device, and the chemical additive device via a wired network.

[0023] In some embodiments, the instrumentation device is connected to at least one of the sand mixing device, blending device, and chemical additive device via a wireless network.

[0024] In some embodiments, the instrumentation device also includes a PLC and an HMI.

[0025] In some embodiments, the operating equipment includes multiple fracturing devices, and the instrumentation equipment is equipped with a main switch for wired communication. The fracturing devices include at least a first group of fracturing devices and a second group of fracturing devices. Both the first group of fracturing devices and the second group of fracturing devices include multiple fracturing devices connected in sequence.

Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely to serve as the basis and representative basis for the claims to teach those skilled in the art to use this disclosure in a variety of substantially any suitable detailed structures.

[0039] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this disclosure.

[0040] Example 1

[0041] Figures 1 and 2 illustrate schematic diagrams of the communication system of a fracturing equipment according to an embodiment of this disclosure (solid arrows in Figure 1 indicate wired connections, and dashed arrows indicate wireless connections). As shown in Figures 1 and 2, the communication system of a fracturing equipment provided in this embodiment includes an instrumentation device 10 and operating equipment. The instrumentation device 10 has a control module. The instrumentation device 10 is connected to at least a portion of the operating equipment via a wired network, and the instrumentation device 10 is connected to at least another portion of the operating equipment via a wireless network.

[0042] The control module is used to switch the communication mode between the instrumentation device 10 and the operating equipment according to the operation status of the fracturing equipment. The communication mode includes wired communication mode and wireless communication mode.

[0043] The operational equipment includes fracturing equipment 20, sand mixing equipment 30, blending equipment, and chemical additives. Instrumentation equipment 10 is the core of the fracturing trailer's control and monitoring system, communicating with each piece of operational equipment. It sends control commands to fracturing equipment 20, sand mixing equipment 30, etc., via communication, and monitors and controls the operational data of the equipment. Instrumentation equipment 10 can be equipped with a wired network main communication terminal (i.e., a main switch). The wired network uses a ring redundant network to enhance network redundancy. Corresponding wired interfaces are installed on the operational equipment. The wired network can be Ethernet. Instrumentation equipment 10 is equipped with wireless access points (APs). The number of wireless access points can be one or more, depending on the number and location of the fracturing and sand mixing equipment on site. Wireless communication clients can be added to fracturing equipment 20 and sand mixing equipment 30, etc. The wireless network can be Bluetooth, WiFi, ZigBee, 4G, 5G, etc.

[0044] Each working device and instrument 10 can be connected via both wired and wireless networks, meaning the communication system employs dual wired and wireless backup. The control module can intelligently analyze and assess the network conditions of the working device's environment, switching between wired and wireless communication modes as needed to ensure reliable, continuous, and stable communication between the working device and instrument 10. The control module's switching of communication modes is instantaneous (extremely short, approximately 10ms), barely noticeable to the user, providing a superior communication experience.

[0045] If other brands or models of equipment are temporarily added to the work team, wired and wireless communication functions can be quickly added, or the existing wired or wireless network functions can be used to quickly access the current network, improving work efficiency without affecting the existing network configuration and application.

[0046] The wireless access point and the client communicate using a three-layer switching mechanism. Combined with wired communication between the instrument device 10 and the working equipment, this optimizes the communication transmission mechanism between the control terminal instrument device 10 (control terminal, or PC terminal) and the working equipment (equipment terminal, or PLC terminal). This enables the control terminal to scan and view the equipment terminal, providing online monitoring and enabling the reuse of wired and wireless communication functions. Furthermore, by modifying the client's ARP processing mechanism, client information processing is reduced, client memory usage is decreased, communication speed is increased, packet loss rate is reduced, and communication stability is ensured. In short, this disclosure achieves the reuse of wired and wireless communication functions through relevant functional design, the establishment of a three-layer switching mechanism, and the use of a shared channel.

[0047] This disclosure fully combines the advantages of both wired and wireless communication methods, allowing both to function simultaneously (one is in a default communication standby state, meaning wired and wireless communication modes serve as backups for each other), achieving reasonable compatibility and effectively ensuring stable and reliable communication. For example, by setting the control module in instrumentation device 10, when two or more wired network connections of the working equipment experience interruptions, the interrupted connections can promptly communicate with the control center (instrumentation device 10) via the wireless network, ensuring normal communication between the interrupted connections and devices located far from the control center. Simultaneously, this communication network architecture greatly increases the convenience and stability of on-site network setup, resolving network storms caused by the simultaneous existence of two networks, and also addressing the issue of excessively long switching times between different network modes.

[0048] In practice, this disclosure may also use a wired connection to ensure reliable communication, depending on the work site environment (e.g., when the network layout at the work site is convenient), or it may use a wireless communication mode to communicate (e.g., when the transmission distance is short and the signal stability is good).

[0049] The operational status of the fracturing equipment includes parameters such as the number and location of the equipment, as well as the current communication status between the equipment and the instrumentation equipment 10 (e.g., whether new equipment has joined the communication, and whether the communication network is stable). In this embodiment, the control module can switch to the corresponding communication mode before the fracturing equipment begins operation based on its operational status, or it can automatically switch to the corresponding network communication mode in real time during operation. In practice, the user of the instrumentation equipment 10 can also manually switch to the corresponding network communication mode.

[0050] It is understood that in the above embodiments, each operating device is connected to the instrument device 10 via both wired and wireless networks, and can switch between the required communication modes as needed to ensure communication reliability. In specific embodiments, some operating devices can be connected to the instrument device 10 only via a wired network, while others can be connected only via wireless communication. That is, the choice of either connection method does not affect communication between the operating device and the instrument device 10, making the networking of the fracturing equipment more flexible and avoiding network conflicts or storms, thus ensuring the normal operation of the fracturing equipment. For example, as shown in Figure 1, the sand mixing device 30 is connected to the instrument device 10 only via a wireless network, while the fracturing device 20 is connected to the instrument device 10 via both a wired and wireless network.

[0051] The communication system for fracturing equipment provided in this embodiment of the present disclosure includes a control module installed on the instrumentation equipment 10 of the fracturing equipment. The control module is connected to at least a portion of the operating equipment via a wired network, and the instrumentation equipment 10 is connected to at least another portion of the operating equipment via a wireless network. The control module is used to switch the communication mode between the instrumentation equipment and the operating equipment according to the operating status of the fracturing equipment. The communication mode includes a wired communication mode and a wireless communication mode. Based on the existing simple wired communication mode, the communication mode can be extended to a mode in which wired and wireless communication reliably achieve mutual backup. This can avoid network storms and network conflicts when wired and wireless communication coexist, ensuring stable and reliable communication during the operation of the fracturing equipment and improving the operating efficiency and effectiveness of the fracturing equipment.

[0052] In some embodiments, the operating equipment includes multiple fracturing devices 20, the instrumentation device 10 is equipped with a main switch for wired communication, each fracturing device is equipped with a wired interface, and the main switch and the wired interfaces of each fracturing device 20 are connected end to end to form a ring redundant network.

[0053] The fracturing equipment 20 can be flexibly grouped. For example, as shown in Figure 1, in this embodiment, eight fracturing equipment 20 are set up and divided into two groups. The fracturing equipment 20 in the first group corresponds one-to-one with the fracturing equipment 20 in the second group.

[0054] The main switch on instrument equipment 10 is connected to the wired interface of the first fracturing device (fracturing 1) in the first group of fracturing equipment. The first fracturing device, the second fracturing device (fracturing 2), the third fracturing device (fracturing 3), and the fourth fracturing device (fracturing 4) in the first group of fracturing equipment are connected sequentially through wired interfaces. The fourth fracturing device (fracturing 4) is connected to the eighth fracturing device (fracturing 8) in the second group of fracturing equipment through a wired interface. The eighth fracturing device, the seventh fracturing device (fracturing 7), the sixth fracturing device (fracturing 6), and the fifth fracturing device (fracturing 5) in the second group of fracturing equipment are connected sequentially. The fifth fracturing device (fracturing 5) is connected to the main switch on instrument equipment 10 through a wired interface. The main switch, the first group of fracturing equipment (connected sequentially within the group), and the second group of fracturing equipment are connected end to end to form a ring redundant network. The ring redundant network can ensure that the signal sent by one device 20 can be seen by all other devices on the ring, and can issue alarm information in a timely manner when communication is interrupted, thus ensuring communication reliability.

[0055] In the above embodiments, a ring-shaped redundant network is constructed based on the grouping of the fracturing equipment 20. In a specific implementation, as shown in Figure 2, the fracturing equipment 20 may not be grouped together, and the main switch is connected to each fracturing equipment 20 end to end to form a ring-shaped redundant network.

[0056] In some embodiments, as shown in FIG2, the instrument device 10 is provided with a first wireless module, and each of the working devices is provided with a second wireless module that communicates wirelessly with the first wireless module. The first wireless module is a wireless access point, and the second wireless module is a client. Each working device communicates wirelessly with the instrument device 10, making communication convenient and flexible.

[0057] As can be seen from the above, this disclosure, while ensuring that the simultaneous existence of wired and wireless communication will not lead to network storms, adds wireless communication redundancy to the existing hardware redundancy (wired redundant network), achieving multiple redundancy and effectively improving the reliability and stability of the communication network. In some embodiments, the wireless communication mode is the default communication mode between the instrument device 10 and the operating device, and the control module includes:

[0058] A detection unit, wherein the detection unit is used to detect the wireless communication strength of the wireless network;

[0059] A switching unit is configured to switch the communication mode between the instrument device 10 and the working device according to the wireless communication strength of the wireless network. If the wireless communication strength is less than a first preset strength threshold, the switching unit switches the communication mode between the instrument device and the working device to a wired communication mode.

[0060] When the work equipment is in operation, it communicates with the instrument device 10 via a wireless network by default. The detection unit can detect the wireless communication strength of the wireless network in real time and send it to the switching unit. After obtaining the wireless communication strength detected by the detection unit, the switching unit determines whether to switch the communication mode based on the wireless communication strength. When the wireless communication strength is less than the first preset strength threshold, it is determined that the wireless network between the instrument device 10 and the work equipment is not working, which may lead to communication interruption. At this time, the switching unit instantly switches the communication mode to the wired communication mode, so that the work equipment and the instrument device 10 communicate through the wired network to ensure the reliability of communication. When the wireless communication strength is greater than or equal to the first preset strength threshold, it is determined that the wireless network between the instrument device 10 and the work equipment is working. At this time, the switching unit does not need to switch the communication mode.

[0061] In specific implementation, the detection unit can detect the wireless communication strength of the first wireless communication module and / or the second wireless communication module, and detect the wireless communication strength of the wireless network. If the wireless communication strength of any wireless communication module is less than the first preset strength threshold, the switching unit can determine that it needs to switch to wired communication mode.

[0062] In some embodiments, the wireless communication mode is the default communication mode between the instrument and the operating device, and the control module includes:

[0063] A detection unit, wherein the detection unit is used to detect the number of packet losses in the wireless network;

[0064] A switching unit is configured to switch the communication mode between the instrument device and the work device according to the number of packet losses in the wireless network. If the number of packet losses in the wireless network is greater than a first threshold, the switching unit switches the communication mode between the instrument device and the work device to a wired communication mode.

[0065] In this embodiment, the working device is still assumed to communicate with the instrument device 10 via a wireless network. The switching unit determines whether to switch the communication mode based on the number of packet losses during wireless communication. When the number of packet losses in the wireless network is greater than a first threshold, it is determined that the wireless communication is unreliable. At this time, the switching unit instantly switches the communication mode to the wired communication mode, so that the working device and the instrument device 10 communicate via a wired network, ensuring the reliability of the communication. When the number of packet losses in the wireless network is less than or equal to the first threshold, it is determined that the wireless network communication between the instrument device 10 and the working device is reliable. At this time, the switching unit does not need to switch the communication mode.

[0066] In some embodiments, the detection unit is further configured to detect the number of packet losses in the wired network; the switching unit is further configured to switch the communication mode between the instrument and the operating equipment to a wireless communication mode when the number of packet losses in the wired network is greater than a second quantity threshold and the wireless communication strength of the wireless network is greater than a second preset strength threshold.

[0067] The switching between wired and wireless communication modes is bidirectional. That is, when there are too many packet losses in wired communication and the wireless signal strength is higher than the second preset strength threshold, the switching unit will switch the communication mode to wireless communication mode, so that the data flow is transmitted wirelessly, thus fully ensuring the reliability of device communication.

[0068] It should be noted that the control module can be an independent controller arranged on the instrument device 10, or it can be part of the main switch and / or wireless access point. That is, the main switch on the instrument device 10 is connected to the first wireless communication module, and the main switch or the first wireless communication module (or the main switch and the first wireless communication module) realize the switching of communication mode.

[0069] In some embodiments, the detection unit is further configured to detect wired disconnection faults between the instrument device 10 and the working device; the control module is further configured to control the working device to perform normal operation when the number of wired disconnection faults is less than a preset number of disconnection thresholds.

[0070] Since the main switch of the instrument device 10 and each working device are connected through a ring redundant network in this embodiment, the main switch can quickly (e.g., within 300 milliseconds) restore communication when the network encounters a fault. In order to avoid arbitrary shutdown of the working devices (e.g., frequent shutdowns may damage the devices), in this embodiment, the wired disconnection fault between the instrument device 10 and the working devices is detected by the detection unit. When the number of wired disconnection faults does not exceed two, the working devices are controlled to continue to work normally. The system also detects in a timely manner whether the wired disconnection will affect the normal operation of the working devices. If the wired disconnection affects the normal operation of the working devices, the working devices are then controlled to stop working.

[0071] In some embodiments, the instrument device 10 is connected in series with at least one of the sand mixing device 30, the mixing equipment, and the chemical additive device via a wired network, and / or the instrument device 10 is connected to at least one of the sand mixing device 30, the mixing equipment, and the chemical additive device via a wireless network.

[0072] The sand mixing equipment 30, the blending equipment, and the chemical additive equipment are usually a single unit. Therefore, they can be connected in series via a wired network to reduce the number of wired network configurations. The sand mixing equipment 30, the blending equipment, and the chemical additive equipment can be connected in series sequentially or end-to-end to form a ring redundant network.

[0073] The sand mixing equipment 30, the mixing equipment, and the chemical additive equipment can also be connected to the first wireless communication module on the instrument equipment 10 through the second wireless communication module installed on them, so as to realize wireless communication.

[0074] In some embodiments, as shown in FIG2, the instrument device 10 also has a PLC (Programmable Logic Controller) and an HMI (Handheld Machine), which can realize local control of the operating equipment and fully ensure the communication efficiency of local control.

[0075] The communication system for fracturing equipment provided in this embodiment of the present disclosure includes a control module installed on the instrumentation equipment of the fracturing equipment. The control module is connected to at least a portion of the operating equipment via a wired network, and the instrumentation equipment is connected to at least another portion of the operating equipment via a wireless network. The control module is used to switch the communication mode between the instrumentation equipment and the operating equipment according to the operating status of the fracturing equipment. The communication mode includes a wired communication mode and a wireless communication mode. Based on the existing simple wired communication mode, the communication mode can be extended to a mode in which wired and wireless communication reliably achieve mutual backup. This can avoid network storms and network conflicts when wired and wireless communication coexist, ensuring stable and reliable communication during the operation of the fracturing equipment and improving the operating efficiency and effectiveness of the fracturing equipment.
