[0038] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0039] To better understand the intelligent coiled tubing equipment and its control method provided by the embodiments of the present invention, we first introduce its application background. The coiled tubing operation device is an operating machine widely used in the fields of well repair, drilling, completion, fracturing, logging, etc. The pump truck is the core of the high-pressure fluid power system in coiled tubing operations, used to provide high-pressure, high-precision fluid transportation to support complex operations such as fracturing and acidizing. Generally speaking, the displacement of the pump truck often represents the actual displacement of the high-pressure fluid in the coiled tubing operation. Therefore, the actual displacement is generally controlled by setting the displacement of the pump truck.

[0040] However, in actual applications, it is found that the actual displacement of high-pressure fluid is often affected by many complex factors such as sensor accuracy and measurement method limitations, system independent control and data silos, and insufficient adaptability to dynamic working conditions. This leads to deviations between the actual displacement and the preset displacement, that is, the displacement of the pump truck does not match the actual displacement measured by the flow meter on the drum. This increases the safety risk of the operation and requires frequent manual adjustment of parameters, which affects construction efficiency.

[0041] Therefore, how to ensure the consistency between the displacement of the pump truck and the displacement of the drum flow meter, thereby reducing operational safety risks and ensuring construction efficiency, has become an important issue that needs to be solved urgently.

[0042] In the above application context, an embodiment of the present invention provides an intelligent coiled tubing device and a control method thereof, which can ensure the consistency between the displacement of the pump truck and the actual displacement, reduce operation safety risks, and improve construction efficiency.

[0043] The following combination Figures 1-10 The intelligent coiled tubing equipment and control method thereof of the present invention are described.

[0044] Figure 1 FIG. 1 is a flow chart of a method for controlling an intelligent coiled tubing device according to an embodiment of the present invention. Figure 1 As shown, the method includes the following steps: Step S10: obtaining the actual flow rate of the high-pressure manifold 112 on the roller skid 11 in real time.

[0045] Specifically, the high-pressure manifold 112 is an important component used to connect the pump truck, the roller skid 11 and the wellhead in continuous tubing operations. Its main function is to control and guide the flow of high-pressure fluid to ensure the safety and efficiency of the operation. By installing a flow meter 16 and a pressure sensor on the high-pressure manifold 112, the fluid data can be monitored in real time and the actual flow rate of the high-pressure fluid can be measured.

[0046] Based on actual needs and different measurement principles, the flow meter 16 can also be selected into different types, for example, a volumetric flow meter, a differential pressure flow meter, a velocity flow meter, etc. The embodiment of the present invention does not impose specific restrictions on the type of the flow meter 16.

[0047] Specifically, the flow meter 16 can be installed at any position on the high-pressure manifold 112 where the flow rate can be monitored. In this embodiment, the flow meter 16 is located on the inner side of the roller body 111 of the roller skid 11 and is connected to the middle of the high-pressure manifold 112. The flow rate here is stable and the measurement value is more accurate (see Figure 8 and Figure 9 ). In addition, in order to improve the flow monitoring accuracy, more than one flow meter 16 can be used for redundant monitoring.

[0048] Step S20: When it is determined that the deviation between the actual flow rate and the preset flow rate is within the preset range, the output displacement of the pump truck cluster 12 is adjusted to make the actual flow rate equal to the preset flow rate.

[0049] Specifically, the preset flow rate is determined by comprehensively considering construction factors such as downhole operating conditions, operational objectives, and safety restrictions. Once the preset flow rate is determined, the pump truck cluster 12 is adjusted to the output displacement corresponding to the preset flow rate. After obtaining the actual flow rate, the actual flow rate is compared with the preset flow rate, and the deviation between the two is calculated. If the deviation is within the preset range, it indicates that the deviation is not caused by a fault. In this case, the output displacement of the pump truck cluster 12 is adjusted to make the actual flow rate equal to the preset flow rate.

[0050] The preset range value of the deviation between the preset flow and the actual flow needs to be determined by comprehensively considering factors such as engineering experience, equipment characteristics, and downhole working conditions, and gradually improved through dynamic adjustment and historical data optimization. Specifically, the flow response of the pump truck cluster 12 under different working conditions can be tested through a ground simulation loop to determine the rationality of the deviation value range.

[0051] As a specific embodiment of the present invention, the preset range of the deviation value between the actual flow rate and the preset flow rate is ±5%.

[0052] Specifically, when the deviation value does not exceed the preset range, when the actual flow rate is greater than the preset flow rate, the displacement of the pump truck cluster 12 is reduced to reduce the actual flow rate; when the actual flow rate is equal to the preset flow rate, the current displacement of the pump truck cluster 12 is maintained; when the actual flow rate is less than the preset flow rate, the displacement of the pump truck cluster 12 is increased to increase the actual flow rate.

[0053] Specifically, the actual flow rate of high-pressure fluid can be dynamically adjusted based on the PID (proportional-integral-differential controller) closed-loop control algorithm. By monitoring the deviation between the actual flow rate and the set flow rate in real time, the actual flow rate can be dynamically adjusted using a combination of three parameters: proportional (P), integral (I) and differential (D). This ensures that the actual flow rate is equal to the preset flow rate or is maintained near the preset flow rate, ensuring that the deviation is minimized to achieve precise control.

[0054] Step S30: When it is determined that the deviation between the actual flow rate and the preset flow rate exceeds the preset range, the abnormality handling mechanism is triggered to perform fault handling.

[0055] Specifically, when the deviation between the actual flow rate and the preset flow rate exceeds the preset range, it indicates that the deviation is likely caused by a fault, and the problem cannot be solved by simply adjusting the output flow rate of the pump truck cluster 12. At this time, the exception handling mechanism is triggered to handle the fault.

[0056] In one embodiment of the present invention, step S30 includes: Step S300: Pre-store multiple fault types and their corresponding solutions.

[0057] Step S310: According to the set priorities, solutions corresponding to different fault types are called in sequence until multiple solutions are called or the deviation between the actual flow rate and the preset flow rate returns to the preset range.

[0058] Specifically, when the deviation between the actual flow rate and the preset flow rate exceeds the preset range, it is determined to be a fault. At this time, the pre-stored solutions corresponding to different fault types are called in sequence according to the set priority. If the deviation between the actual flow rate and the preset flow rate returns to the preset range after calling a solution, the fault is now eliminated, the solution call is stopped, and normal operation is resumed. If the fault is still not resolved after all solutions have been called, it means that the current fault type and its corresponding solution have not been pre-stored. In this case, the instruction is frozen and the manual confirmation process is triggered for manual processing.

[0059] With this arrangement, when a fault occurs, if the corresponding fault type and solution have been pre-stored, the fault can be quickly resolved. If the corresponding fault type and solution have not been pre-stored, it will also be convenient for staff to quickly check the fault type and quickly find a suitable solution.

[0060] In a specific embodiment of the present invention, the fault type includes network interruption; and the solution corresponding to the network interruption fault is: calling local cache data.

[0061] Specifically, under normal network conditions, the system will store data in the local cache and the cloud monitoring platform 40 at the same time. When the network is interrupted, the system cannot establish communication with the cloud monitoring platform 40. At this time, the local cache data of the instrument vehicle is called to maintain basic control.

[0062] In a specific embodiment of the present invention, the fault type includes sensor failure; the solution corresponding to the sensor failure is: digital twin simulation.

[0063] Specifically, digital twin simulation builds a virtual model that is highly consistent with the physical system, generating replacement data in the event of sensor failure to ensure continuous system operation. Its core relies on high-fidelity digital models, real-time data synchronization, and intelligent algorithm analysis. The specific principles of digital twin simulation can be referenced in existing technologies and will not be elaborated in detail in the present embodiments.

[0064] In one embodiment of the present invention, in step S301, the priority of each fault type is determined based on the historical frequency of the fault. This adaptive prioritization mechanism based on historical fault frequency can quickly locate high-frequency or high-impact faults, prioritize resource allocation, and significantly shorten mean time to recovery.

[0065] Specifically, the call priority setting of the fault type includes the following steps: Arrangement S301: Sort the fault types according to their historical occurrence frequencies and generate a priority list.

[0066] Step S302: After the fault processing is completed, the historical occurrence frequency of the fault type is updated according to the processing result, and the priority list is regenerated.

[0067] With this setup, through closed-loop feedback—that is, updating and reordering frequency data after fault processing—the system can dynamically adapt to changes in fault patterns, such as the emergence of new faults or frequency fluctuations, continuously optimize resource allocation strategies, reduce redundant processing and manual intervention, and ultimately improve operation and maintenance efficiency, reduce the risk of system interruption, and enhance the intelligence and reliability of fault management.

[0068] In another aspect, an embodiment of the present invention further provides a control device for an intelligent coiled tubing device, comprising: An acquisition module, adapted to acquire the actual flow of the roller skid 11 in real time; The determination module is suitable for adjusting the output displacement of the pump truck cluster 12 so that the actual flow is equal to the preset flow when the deviation between the actual flow and the preset flow is within the preset range; when it is determined that the deviation between the actual flow and the preset flow exceeds the preset range, triggering the exception handling mechanism to handle the fault.

[0069] In one embodiment of the present invention, the control device 30 also includes a storage module and a calling module; wherein the storage module is suitable for pre-storing multiple fault types and their corresponding solutions; the calling module is suitable for calling solutions corresponding to different fault types in sequence according to the set priority until multiple solutions are called or the deviation between the actual flow and the preset flow is restored to the preset range.

[0070] In one embodiment of the present invention, the control device 30 further includes a generation unit, which generates a freeze instruction, sends an alarm, and triggers a manual confirmation process if the fault has not been eliminated after multiple solutions are called.

[0071] In one embodiment of the present invention, the control device 30 also includes a sorting module and an updating module; wherein the sorting module is adapted to sort the fault types according to the historical occurrence frequencies of different fault types and generate a priority list; and the updating module is adapted to update the historical occurrence frequencies of the fault types according to the processing results after the fault processing is completed and regenerate the priority list.

[0072] On the other hand, referring to Figures 3 to 9 An embodiment of the present invention further provides an intelligent coiled tubing device, comprising a wellsite equipment layer 10, a communication module 20, and a control device 30 provided by any of the above embodiments, which is communicatively connected to the wellsite equipment layer 10 via the communication module 20.

[0073] The wellsite equipment layer 10 includes a roller skid 11, a pump truck cluster 12, and a data acquisition module. The data acquisition module is adapted to collect operating parameters of the wellsite equipment layer 10, including the actual flow rate of the high-pressure manifold 112 on the roller skid 11. The control device 30 is adapted to obtain the actual flow rate and, if the deviation between the actual flow rate and the preset flow rate is within a preset range, adjust the output displacement of the pump truck cluster 12 to equalize the actual flow rate to the preset flow rate. If the deviation between the actual flow rate and the preset flow rate is determined to exceed the preset range, trigger an exception handling mechanism to handle the fault.

[0074] In one embodiment of the present invention, the roller skid 11 comprises a base 110, a roller body 111, and a high-pressure manifold 112. The roller body 111 is rotatably supported on the base 110. Specifically, the roller body 111 and the base 110 can be connected using a shaft seat. The high-pressure manifold 112 is connected to the oil pipe inlet on the roller body 111 via a rotary joint. The data acquisition module includes a flowmeter 16, which is located inside the roller body 111 and connected to the center of the high-pressure manifold 112. This location provides stable flow and effectively improves monitoring accuracy.

[0075] Depending on the measurement principle, the flow meter 16 may also be a volumetric flow meter, a differential pressure flow meter, a velocity flow meter, etc. The embodiment of the present invention does not impose any specific restrictions on the type of the flow meter 16.

[0076] In one embodiment of the present invention, the roller skid 11 also includes a lubricating oil module 113, and the data acquisition module also includes an angle sensor 13: the angle sensor 13 is used to collect the rotation angle of the roller body 111, and the control device 30 controls the lubricating oil module 113 to spray lubricating oil into the oil pipe based on the rotation angle of the roller body 111.

[0077] Specifically, when the angle sensor 13 detects that the rotation angle of the drum body 111 reaches a set value, the lubricating oil module 113 is controlled to spray lubricating oil into the oil pipe.

[0078] Specifically, the angle sensor 13 includes an electric slip ring, a fixed ring fixing plate 114 is connected to the base 110, and a dynamic ring fixing plate 115 is connected to the roller body 111. The outer ring of the electric slip ring is connected to the fixed ring fixing plate 114, and the inner ring is connected to the dynamic ring fixing plate 115. In this way, the rotation angle of the roller body 111 is monitored.

[0079] In one embodiment of the present invention, the data acquisition module further includes an oil pipe length monitor, and the oil pipe length monitor is used to monitor the retracted and extended length of the oil pipe.

[0080] Specifically, the oil pipe length monitor includes a light sensor 14 and a reflector 15 ; one of the light sensor 14 and the reflector 15 can rotate synchronously with the drum body 111 , and the light sensor 14 measures the retracted and extended length of the oil pipe by monitoring the relative rotation angle of the reflector 15 .

[0081] Specifically, the reflector 15 is connected to the inner side of the shaft seat and can be synchronized with the drum body 111, and the light sensor 14 is connected to the flow meter 16. The light sensor 14 records the rotation angle and number of revolutions of the drum body 111, and with the algorithm, it can accurately count the length of the oil pipe lowered.

[0082] It should be pointed out here that the above description of the structure of the roller skid 11 is only a brief description, the purpose of which is to enable a more intuitive understanding of the connection positions of the various sensors in the data monitoring module on the roller skid 11. Of course, in order to realize its own functions, the roller skid 11 also includes other structures or components. For the working principle of the roller skid 11, more specific structure, and the coordination relationship between structures, reference can be made to the existing technology. Since it is not the main improvement point of the present invention, it will not be described in detail in the embodiments of the present invention.

[0083] In one embodiment of the present invention, communication module 20 can utilize a wireless network for communication. Specifically, a 5G private network base station and mesh nodes form the network infrastructure layer. The 5G private network base station provides a low-latency (<20ms) communication channel for real-time command transmission between the control device 30 and the wellsite equipment layer 10. The mesh nodes serve as a redundant network, automatically switching when the 5G signal is interfered with to ensure control link stability.

[0084] It is understood that those skilled in the art may combine and integrate different embodiments or examples and features of different embodiments or examples described in this specification without mutual contradiction.

[0085] Through the intelligent continuous tubing equipment and control method provided by the embodiments of the present invention, when the deviation value does not exceed the preset range, when the actual flow rate is greater than the preset flow rate, the displacement of the pump truck cluster 12 is reduced to reduce the actual flow rate. When the actual flow rate is equal to the preset flow rate, the current displacement of the pump truck cluster 12 is maintained. When the actual flow rate is less than the preset flow rate, the displacement of the pump truck cluster 12 is increased to increase the actual flow rate. When the deviation between the actual flow rate and the preset flow rate exceeds the preset range, it indicates that this deviation is likely caused by a fault. Obviously, the problem cannot be solved by simply adjusting the output flow rate of the pump truck cluster 12. At this time, the exception handling mechanism is triggered to handle the fault. In this way, the consistency between the pump truck displacement and the actual displacement can be effectively ensured, the operational safety risk can be reduced, and the construction efficiency can be improved.

[0086] In another aspect, the present invention further provides an electronic device, Figure 10An example of a physical structure diagram of an electronic device is shown below. Figure 10 As shown, the electronic device may include: a processor 50, a communications interface 51, a memory 52, and a communications bus 53. The processor 50, the communications interface 51, and the memory 52 communicate with each other via the communications bus 53. The processor 50 may invoke logic instructions in the memory 52 to execute a control method for the intelligent coiled tubing device. The method includes: obtaining the actual flow rate of the high-pressure manifold 112 on the roller skid 11; when it is determined that the deviation between the actual flow rate and the preset flow rate is within a preset range, adjusting the output displacement of the pump truck cluster 12 to equalize the actual flow rate to the preset flow rate; and when it is determined that the deviation between the actual flow rate and the preset flow rate exceeds the preset range, triggering an exception handling mechanism to perform fault processing.

[0087] Furthermore, the logic instructions in the aforementioned memory 52 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention, or the portion that contributes to the prior art, or a portion of the technical solution, can be embodied in the form of a software product. This computer software product, stored in a storage medium, includes instructions for enabling a computer device (which can be a personal computer, server, or network device, etc.) to execute all or part of the steps of the methods described in various embodiments of the present invention.
