Description
Technical Field
[0001] This invention relates to the field of well workover rig technology in the oil and gas industry, specifically to an intelligent electronic control system and method adapted to a multi-functional dual-power well workover rig. Background Technology
[0002] As a key piece of equipment in oilfield operations, well workover rigs in the oil and gas industry have undergone a technological evolution from mechanical transmission to electronic control. Traditional workover rigs primarily use diesel engines as the sole power source, driving winches, traveling blocks, or rotary tables via mechanical transmission routes to complete workover operations. With the promotion of electrification technology, electric workover rigs have begun to use batteries and electric motors to replace diesel engines, reducing emissions to some extent. In recent years, dual-power workover rig technology has gradually matured, introducing battery and electric motor systems while retaining the diesel engine power source, forming a hybrid power architecture. However, this diversification of power sources makes the transmission system increasingly complex, placing higher demands on the vehicle's electronic control system.
[0003] Well workover rigs operate under unique and harsh environments. A malfunction in the electrical control system during workover can easily lead to serious accidents such as blowouts due to the inability to seal the well in time. Existing electrical control systems struggle to meet the stringent requirements of dual-power workover rigs for power supply reliability, intelligent power distribution, and fault tolerance. Especially when simultaneously driving multiple loads such as the main engine, low-voltage system, mud, and solids control system, traditional systems cannot effectively coordinate the mixed power supply demands of AC and DC, and high and low voltage. While patent CN 105514939 A relates to capacitor charging and discharging control in electric workover rigs, it focuses only on energy storage component management and does not address the overall intelligent electrical control issue. Patent CN221995174U's power management system also fails to encompass an integrated solution for overall power distribution and control. Therefore, there is an urgent need to develop an intelligent electrical control system and method adaptable to multi-functional dual-power workover rigs, improving operational convenience and overall safety while ensuring control reliability.

[0013] This application also provides an intelligent electronic control method adapted to a multi-functional dual-power well workover rig, the method comprising the following steps: Step S1, Power Input Stage: Connect an external AC power source through the power input module. The external AC power source comes from the well site grid or the generator room. Step S2, AC power distribution stage: AC power is distributed to the main vehicle power distribution box, wellhead power distribution box and DC conversion module through the AC power distribution module; wherein, the main vehicle power distribution box provides AC power to the disc brake, driller's room, water pump equipment and blower equipment, and the wellhead power distribution box provides AC power to the wellhead injection pump and solids control module; Step S3, DC-DC conversion stage: The AC power is converted into high-voltage DC power by the DC-DC conversion module and output to the DC high-voltage power distribution module; the DC-DC conversion module includes a charger controller and a charger, and the charger controller controls the charger to perform the conversion operation; Step S4, High Voltage DC Power Distribution Stage: The distribution of high voltage DC power is managed through a DC high voltage power distribution module.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. In this section, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can clearly understand the technical solutions and implementation details of the present invention. Identical components or modules are identified using the same reference numerals. It should be noted that directional terms such as "front," "rear," "left," "right," "up," and "down" used below are defined based on the directions shown in the accompanying drawings, while "inner" and "outer" refer to directions toward or away from the geometric center of a specific component. These definitions are for simplification only and do not constitute a limitation on the scope of the present invention.
[0020] To facilitate understanding of this invention, the technical solutions will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this invention. This invention provides an intelligent electronic control system and method adapted to a multi-functional dual-power workover rig. This system, through integrated power management, power distribution control, and communication logic, enables efficient and reliable operation of the workover rig in dual-power (such as diesel engine and battery motor) mode. In particular, the system can adapt to well site grid power or generator room power supply, and reduces the power demand of external power sources through intelligent allocation, thereby improving the overall intelligence and economy of the machine.
[0021] Reference Appendix Figure 1 - Appendix Figure 3 The logical principle of the intelligent electronic control system of this invention is as follows: Figure 1 As shown, its core lies in achieving flexible power distribution and control through modular design. The system mainly includes a power input module, an AC power distribution module, a DC-DC conversion module, a DC high-voltage power distribution module, a battery module, an intelligent thermal management module, multiple execution modules, and a control module. These modules form a complete power distribution path through electrical connections, while the control module enables signal interaction and coordinated control between the modules via a communication bus (such as a CAN bus).
[0022] Specifically, the power input module is used to connect to external AC power sources, including well site power grid 1 and generator room 2. The outputs of well site power grid 1 and generator room 2 are connected to the AC power distribution module, forming a dual power input channel. This design allows the system to automatically switch power supply between well site power grid 1 and generator room 2, ensuring a seamless transition in the event of a power failure, thereby improving system reliability. For example, when well site power grid 1 is interrupted, the system can immediately switch to generator room 2 for power supply, avoiding interruption of well workover operations.
[0023] The AC power distribution module is coupled to the power input module and is mainly used to receive and distribute AC power from the power input module. In this embodiment, the AC power distribution module specifically includes the main unit power distribution box 3. The main unit power distribution box 3 distributes the input AC power to three branches: the main unit power distribution box 4, the wellhead power distribution box 5, and the DC-DC conversion module. The main unit power distribution box 4 is an AC power distribution box specifically for powering the main equipment of the workover rig, such as disc brakes, driller's cabin (driller's box), water pump equipment, blower equipment, and other auxiliary equipment. The wellhead power distribution box 5 is also an AC power distribution box, used to power the wellhead equipment, such as the wellhead injection pump, wellhead solids control system, and other wellhead auxiliary equipment. This separate box design ensures independent power supply for the main unit and the wellhead equipment, avoids mutual interference, and meets the needs of complex well site conditions.
[0024] A DC-DC conversion module is coupled to an AC power distribution module to convert the AC power distributed by the AC power distribution module into high-voltage DC power. Specifically, the DC-DC conversion module includes a charger controller 6 and a charger 7. The charger controller 6 controls the charger 7 to convert input AC power (not limited to 380V) into high-voltage DC power (such as 600V or 800V specifications) and output it to the DC high-voltage power distribution module 8. The charger 7 is designed to accommodate various input voltages, improving system compatibility.
[0025] DC high voltage power distribution module 8 (in) Figure 1 The module marked 8) is coupled to the DC-DC converter module for distributing high-voltage DC power. This module employs a DC high-voltage power distribution bus structure, receiving power not only from the DC-DC converter module but also forming a dual-channel interconnection circuit with the battery module. For example... Figure 2 As shown, the DC high-voltage power distribution module circuit principle further illustrates the connection relationship between the external power source (well site grid power 1 or generator room 2) and the energy storage battery. The channel between the external power source and the battery module is always open, allowing for switching of input and output at any time, thereby dynamically adjusting the power supply priority. This design significantly reduces the power demand on the external power source; for example, the input power demand of the external power source can be reduced by 60% or more. At the same time, the buffering effect of the battery module ensures the stability of the system under load fluctuations.
[0026] The battery module is coupled to the DC high-voltage power distribution module 8 for energy storage and discharge. The battery module includes a power battery pack and a high-voltage battery box. The DC high-voltage power distribution module 8 supplies high-voltage power to the TMS in the intelligent thermal management module through the high-voltage battery box in the power battery pack. The intelligent thermal management module manages the temperature of the power battery pack and includes components such as heaters, radiators, water pumps, and water tanks. Through active cooling or heating, it controls the temperature of the battery module, ensuring that the battery operates within its optimal temperature range, extending battery life and improving safety.
[0027] Multiple execution modules are coupled to the DC high-voltage power distribution module 8 to receive high-voltage DC power and drive various power and auxiliary equipment of the workover rig. These execution modules include: Motor controller 19: Converts high-voltage DC power into AC power to drive winch motor 9 and control the hoisting operation of the well workover rig; Oil pump controller 20: Converts high-voltage DC power to AC power to drive oil pump motor 10 for oil supply to the hydraulic system; Motor controller 2 11 and motor controller 3 12: respectively convert high-voltage DC power into AC power to drive mud pump motor 1 13 and mud pump motor 2 14 for wellhead mud treatment; The DC-DC / AC controller 15 converts high-voltage DC power to AC power to drive the air compressor motor 16, and simultaneously converts high-voltage DC power to low-voltage DC power to supply the auxiliary battery 17. The auxiliary battery 17 supplies power to low-voltage electrical equipment such as the vehicle lighting system, vehicle controller, and low-voltage control module, ensuring the normal operation of the auxiliary system.
[0028] The control module, as the core of the system, is communicatively connected to the DC high-voltage power distribution module 8 and multiple execution modules for overall coordinated control. In this embodiment, the control module is specifically the central processing unit 18. The central processing unit 18 establishes communication connections with the DC high-voltage power distribution module 8, charger controller 6, motor controller 19, oil pump controller 20, motor controller 11, motor controller 12, and DC-DC / AC controller 15 via a CAN bus to achieve real-time data exchange. Furthermore, the central processing unit 18 is also communicatively connected to operation input devices, such as the undercarriage control box, the driller's control room, and an external remote control, to receive operator commands. Through this integrated control, the central processing unit 18 can dynamically adjust the power distribution strategy according to load demands, for example, prioritizing battery power to reduce noise and pollution, or switching to external power during peak loads.
[0029] This invention also provides an intelligent electronic control method adapted to a multi-functional dual-power workover rig. This method is implemented through the aforementioned system and specifically includes the following steps: Step S1, Power Input Stage: Connect to an external AC power source via the power input module. The external AC power source comes from the well site power grid 1 or the generator room 2. The system automatically detects power availability and switches between the two power sources to ensure continuous power supply.
[0030] Step S2, AC Power Distribution Stage: AC power is distributed to the main engine distribution box 4, the wellhead distribution box 5, and the DC-DC conversion module via the AC power distribution module (main engine distribution box 3). The main engine distribution box 4 provides AC power to the disc brakes, driller's cabin, water pump equipment, and blower equipment, while the wellhead distribution box 5 supplies power to wellhead equipment such as the wellhead injection pump and solids control module. This distribution logic ensures zoned power supply for well site equipment, preventing overload.
[0031] Step S3, DC-DC Conversion Stage: The AC power is converted to high-voltage DC power via the DC-DC conversion module. The charger controller 6 controls the charger 7 to perform the conversion operation, outputting high-voltage DC power to the DC high-voltage power distribution module 8. During the conversion process, the system monitors the input voltage and current to ensure conversion efficiency and safety.
[0032] Step S4, High-Voltage DC Power Distribution Stage: The distribution of high-voltage DC power is managed through the DC high-voltage power distribution module 8. This module forms a dual-channel interconnected circuit with the battery module, dynamically switching the power supply priority between the external power source and the battery module according to real-time load demands (such as the power requirements of the winch motor or mud pump motor). For example, battery power is prioritized under low load conditions to save energy; under high load conditions, the external power source is automatically switched on to ensure power output.
[0033] Step S5, Battery Management Stage: Energy storage and discharge are performed through the battery module. The DC high-voltage power distribution module 8 supplies high-voltage power to the TMS in the intelligent thermal management module through the high-voltage battery box in the power battery pack. At the same time, the intelligent thermal management module actively regulates the temperature of the battery module through heaters, radiators, water pumps and water tanks. For example, it starts a cooling cycle when the temperature is high to prevent the battery from overheating.
[0034] Step S6, Execution Control Phase: Control commands are sent to multiple execution modules via the control module (Central Processing Unit 18). Specifically, this includes: The motor controller 19 drives the winch motor 9 to realize the lifting and lowering operations of the workover rig; The oil pump controller 20 drives the oil pump motor 10 to provide power to the hydraulic system; The motor controller 211 and the motor controller 312 drive the mud pump motor to process wellhead mud; The DC-DC / AC controller 15 drives the air compressor motor 16 and charges the auxiliary battery 17 to ensure the stable operation of the low-voltage equipment.
[0035] Step S7, Communication and Monitoring Phase: The control module exchanges real-time data with each module via the CAN bus and receives operation commands from the undercarriage control box, the driller's control room, and the external remote controller. Simultaneously, the system also includes a remote IoT module, communicatively connected to the central processor 18, for remotely monitoring the overall machine operating status (such as voltage, current, and temperature parameters) and performing fault diagnosis. This improves the system's maintainability and intelligence.
[0036] Through the above system and method, this invention achieves intelligent electronic control of the workover rig in dual-power mode, which not only improves the convenience of operation and operational safety, but also reduces dependence on external power sources, promoting the green and intelligent development of workover rig products. Those skilled in the art can make appropriate modifications based on the above embodiments, but all such modifications should fall within the protection scope of this invention.
