Description

Technical Field

[0001] The present invention relates to the field of oil exploration, and particularly to an oil exploration top drive device and a control system. Background Art

[0002] In the complex and challenging process of oil exploration, the top drive device plays an irreplaceable and crucial role and is a vital part among many devices. Oil exploration operations usually face complex geological conditions, harsh environmental factors, and high-precision operation requirements. As the core device directly acting on the drilling link, the performance of the top drive device is directly related to the success or failure of the entire exploration project.

[0003] However, many problems that cannot be ignored have emerged in the control of the existing top drive devices on the market. Taking the connection control between components as an example, its accuracy and efficiency have not reached the ideal state. During actual operation, due to inaccurate connection control, the coordinated work between different components shows deviations and cannot achieve close cooperation and efficient collaboration. This situation makes the equipment prone to unstable phenomena such as vibration and jamming during operation, which not only increases the wear and failure rate of the equipment, shortens the service life of the equipment, but also often hinders the progress of oil exploration and seriously affects the efficiency of oil exploration. At the same time, the unstable operation state is also difficult to ensure the quality of exploration operations, which may cause deviations in key indicators such as the verticality and depth of drilling, thus affecting subsequent exploitation work.

[0004] Meanwhile, there are obvious defects in the interface function of the existing top drive device control system. This interface fails to provide operators with comprehensive, timely, and intuitive equipment operation information. At the oil exploration site, operators need to constantly monitor multiple operation parameters of the equipment, such as motor speed, torque, oil temperature, pressure, etc., in order to make decisions according to the actual situation. However, the existing control system interface often can only display partial information, or the information update is delayed, which makes it difficult for operators to comprehensively and timely grasp the overall situation of the equipment operation state. In the face of emergencies or when real-time adjustments are required, operators cannot quickly make accurate decisions due to the lack of support from accurate information, further affecting the smooth progress of exploration operations.

[0005] In summary, it has become an urgent need for the industry to develop a control system for the top drive device in oil exploration that combines high efficiency, precision, and convenient operation, which has extremely important practical significance. Such a control system can not only improve the precision and efficiency of the connection control of each component of the top drive device, ensure the stable operation of the equipment, and thus improve the efficiency and quality of oil exploration; but also provide more comprehensive, timely, and accurate equipment operation information for operators by optimizing the control system interface, helping operators make scientific decisions quickly, promoting the development of the oil exploration industry towards a more efficient and intelligent direction.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Refer to Figures 1 to 9, an oil exploration top drive device, comprising a slide rail 1, on which a pulley 7 is provided, and the two are slidably connected. The pulley 7 is fixedly connected to a transmission device 6. Inside the transmission device 6, there is a gearbox 9. On the gearbox 9, there is a dual-power device 3. Below the gearbox 9, there is a slewing device 5 connected. The slewing device 5 is connected to a back-up tong 8 and is also connected to a hook 4. On the gearbox 9, there is also a double-lifting ring device 2. In the oil exploration operation scenario, this oil exploration top drive device operates in coordination with the corresponding control system to jointly achieve efficient and precise drilling work. Its working principle is based on the close cooperation between components and the precise control of the control system, as follows: When the oil exploration top drive device starts and is ready for drilling operations, the control system first conducts an initialization check on each component to ensure that all equipment is in a normal standby state. In terms of the cooperation between the pulley and the slide rail, the control system issues a start command, and the transmission device 6 starts to operate, driving the pulley 7 fixedly connected to it to slide on the slide rail 1. At this time, the control system, with the help of displacement sensors, speed sensors, etc. installed on the pulley 7 and the slide rail 1, real-time obtains the position and speed information of the pulley 7. Once it detects that the operating state of the pulley 7 deviates from the preset trajectory or the speed shows abnormal fluctuations, the control system will quickly respond by precisely adjusting the power output of the transmission device 6 to achieve precise control of the movement of the pulley 7, ensuring that the pulley 7 moves smoothly and accurately along the slide rail 1 and ensuring that the top drive device can quickly and accurately reach the designated drilling position. The gearbox 9, as a key component of transmission, starts to work under the drive of the dual-power device 3. The two drive devices inside the dual-power device 3 operate in coordination to provide stable and strong power for the gearbox 9. The control system evaluates the working state of the dual-power device 3 in real time by monitoring the operating parameters of the drive devices and heat dissipation devices inside the dual-power device 3, such as motor speed, temperature, etc., and the torque and speed data of the transmission components inside the gearbox 9. When it is necessary to adjust the power output, the control system can precisely control the output power and speed of the drive devices inside the dual-power device 3 to ensure that the gearbox 9 obtains stable and matching power input, realizing efficient power transmission and at the same time avoiding additional wear or damage to the gearbox 9 and other components due to unstable power. The slewing device 5 starts to rotate under the drive of the gearbox 9. Since it is respectively connected to the back-up tong 8 and the hook 4, the rotation of the slewing device 5 will drive the hook 4 to rotate, thereby realizing the rotation operation of the drilling tool (such as a drill pipe) for drilling operations. At the same time, under the control of the control system, the back-up tong 8 can, according to the needs of drilling operations, timely clamp or release the drill pipe. For example, when replacing the drill pipe, the back-up tong 8 clamps the drill pipe to prevent it from rotating, so as to smoothly complete the disassembly and installation of the drill pipe; during normal drilling, the back-up tong 8 is released to allow the drill pipe to rotate freely.The control system realizes precise control of the slewing device 5 and the back-up tong 8 by monitoring parameters such as the rotation angle, speed of the slewing device 5, and the clamping force of the back-up tong 8, ensuring the safety and high efficiency of the drilling operation. The double-lifting ring device 2 is mainly used for operations such as the installation, disassembly, and transportation of auxiliary equipment. During actual operations, when it is necessary to lift or lower equipment, the control system will accurately control the lifting and lowering actions of the hook 4 according to information such as the weight and position of the equipment. At the same time, by monitoring the force-bearing situation of the double-lifting ring device 2, the safety and stability of the lifting ring are ensured. During the lifting process, if abnormal force-bearing of a certain lifting ring is detected, the control system will promptly adjust the attitude of the hook 4 or stop the lifting action to avoid tilting or dropping of the equipment due to uneven force-bearing, ensuring the safety of the operating personnel and equipment.

[0032] During the entire drilling operation process, the control system continuously collects data from the sensors of each component to conduct all-round real-time monitoring of the operating state of the equipment. Once abnormal operating parameters of the equipment are detected, such as excessive temperature, excessive vibration, or abnormal pressure of a certain component, the control system will immediately initiate corresponding adjustment strategies. For example, when it is detected that the temperature of a certain component is too high, the control system will automatically increase the power of the heat dissipation device of that component and at the same time appropriately reduce its working load to lower the temperature; if excessive vibration of the equipment is found, the control system will quickly analyze the cause of the vibration, which may be loose connection of components, unbalanced power, etc., and then adjust the operating parameters of the relevant components or issue an alarm to remind the operator to conduct inspection and maintenance to ensure that the equipment is always in a stable and reliable operating state. Through the above precise control strategies, the control system of the present invention realizes the close cooperation and efficient coordinated operation of each component of the top drive device, improving the stability and reliability of the equipment operation. This improvement in stability and reliability enables the oil exploration operation to be carried out more efficiently and precisely. In terms of exploration efficiency, it reduces the downtime caused by equipment failures or unstable operation, speeds up the drilling speed, and shortens the exploration cycle; in terms of exploration quality, precise control ensures that key indicators such as the verticality and depth of the drilling meet the requirements, improving the oil well production efficiency and crude oil output, providing strong technical support for the development of the oil exploration industry.

[0033] As a preferred technical solution, the pulley 7 comprises vertical rails A and B, which are interconnected. A sliding mechanism is provided on vertical rail A, providing a sliding connection between the two. The sliding mechanism is fixedly connected to the top drive. The sliding mechanism comprises a vertical frame and a horizontal frame. The horizontal frame is connected to a set of vertical frames at each end, with the vertical and horizontal frames perpendicular to each other. The vertical frame is connected to vertical rails B, providing a sliding connection between the two. The vertical frame is also fixedly connected to the top drive. As a crucial component of the top drive for oil exploration, the pulley operates on the principle of coordinated movement of multiple components, playing a crucial role in supporting and moving the entire top drive. When the top drive needs to be moved to perform drilling operations at different locations, the pulley is powered by a transmission device 6, which is fixedly connected to it. The power generated by the operation of the transmission device 6 drives the pulley to slide on the slide rail 1. In the pulley structure, vertical rails A and B are interconnected, forming a stable frame structure. The sliding mechanism on vertical rail A is a key component that enables the pulley to move. The sliding mechanism consists of a vertical frame and a horizontal frame, with a vertical frame connected perpendicularly to each end of the horizontal frame. This structural design ensures excellent stability and load-bearing capacity. The vertical frame is connected to the vertical rail B via a sliding connection, enabling the pulley to slide along the direction of the vertical rail B. When power is supplied by the transmission device 6, the force is first transmitted to the sliding mechanism, which is fixedly connected to the top drive. Because the vertical frame is fixedly connected to the top drive, the top drive moves with the movement of the sliding mechanism. During movement, the vertical frame slides along the vertical rail B. The sliding connection between the vertical frame and the vertical rail A also provides auxiliary support and guidance, ensuring smooth and stable movement of the pulley and minimizing wobbling and deviation. The vertical connection between the vertical frame and the horizontal frame ensures that the weight of the top drive is evenly distributed during the movement of the pulley, preventing localized wear or damage caused by uneven force. This structure also enhances the overall rigidity and stability of the pulley, allowing it to maintain excellent operating conditions even under heavy loads. To ensure safe and stable operation during the trolley's movement, appropriate monitoring and control mechanisms are employed. For example, vertical rails A and B are equipped with displacement sensors, speed sensors, and limit switches. The displacement sensors monitor the trolley's position in real time, the speed sensors monitor its speed, and the limit switches prevent it from exceeding its safe range of movement. These sensors transmit data to the control system. If the control system detects anomalies in the trolley's position or speed, or if it is about to reach its limit, it immediately issues a command to the transmission device 6 to adjust power output, causing the trolley to slow down, stop, or change direction, thereby ensuring safe and reliable operation.In summary, the pulley provides power through the transmission device 6. By virtue of the sliding connection between the vertical frame and the vertical rail B and its unique structural design, it realizes smooth and accurate movement on the slide rail 1, providing a reliable guarantee for the positioning of the top drive device at different positions in oil exploration operations.

[0034] As a preferred technical solution, the double lifting ring device includes a top drive device. The top of the top drive device is connected to a connecting device. A gearbox is provided at the bottom of the top drive device. The connecting device and the gearbox are connected by a lifting ring, and the connection mode between the lifting ring and the connecting device is a movable connection, and the connection mode between the lifting ring and the gearbox is a rotational connection. The connecting device includes a block, a connecting hole, a lifting ring hole and a locking device. The block is connected to the top drive device and the two are connected by a shaft. A connecting hole and a lifting ring hole are formed on the block. At the same time, two symmetrically arranged locking devices are also provided on the block, and a lifting ring is placed in each locking device. The double lifting ring device plays a key auxiliary role in the top drive device for oil exploration. Its working principle is based on the ingenious connection and coordinated operation of each component to ensure safety and efficiency during equipment installation, disassembly and lifting operations. When the top drive device is operating normally or performing related operations, the double lifting ring device is first closely connected to the top drive device through the connecting device. The block of the connecting device is connected to the top of the top drive device by a shaft. This shaft connection method not only ensures the stability of the connection, but also allows the block to rotate relatively within a certain range to adapt to the angle change requirements under different operating conditions. The connecting hole on the block may be used to further connect to other auxiliary equipment or lifting ropes to enhance the applicability of the device in a complex operating environment. The lifting ring plays a core role in the working process of the double lifting ring device. The lifting ring is movably connected to the connecting device, which allows the lifting ring to move flexibly within the lifting ring hole of the connecting device and automatically adjust its posture according to the center of gravity and the force direction of the object during the lifting process to ensure the smoothness of the lifting. The lifting ring is rotationally connected to the gearbox, which means that when the top drive device needs to perform a rotating operation (such as when the gearbox drives the drill pipe to rotate during drilling), the lifting ring will not be affected by the additional torque due to the rotation of the gearbox, avoiding damage to the lifting structure, and at the same time ensuring that the lifting ring will not interfere with the normal operation of the gearbox when it is in a non-lifting state. The two symmetrically arranged locking devices provided on the block are an important part to ensure the safe operation of the double lifting ring device. Before the lifting operation, the operator places the lifting ring in the locking device and locks it. The locking device can effectively prevent the lifting ring from accidentally coming out during the lifting process and ensure the safety of the lifting operation. The symmetrically arranged locking devices can evenly share the tension borne by the lifting ring, improve the overall load-bearing capacity of the device, and avoid damage to the lifting ring or connecting components due to uneven force. When the lifting ring is not needed for the lifting operation, the locking device can also fix the lifting ring in a suitable position to prevent it from shaking randomly and affecting the normal operation of the top drive device. During the installation of oil exploration equipment, when the top drive device needs to be lifted and transported to a designated position, the rope of the lifting equipment will be connected to the lifting ring of the double lifting ring device. Since the lifting ring can move and rotate, it can quickly adapt to the angle of the lifting rope and the posture change of the top drive device itself to ensure that the top drive device remains balanced during the lifting process and avoid dangerous situations such as tilting and shaking.When disassembling the top drive device, the double lifting ring device also plays a role. By cooperating with the lifting equipment through the lifting rings, the top drive device can be safely and stably lifted from the working position. In addition, during the daily maintenance or component replacement of the top drive device, if it is necessary to lift some components, the double lifting ring device can also provide a reliable connection point for the lifting operation. With its reasonable structural design and connection method, the smooth progress of the lifting operation is guaranteed.

[0035] As a preferred technical solution, the gearbox includes a box body. Inside the box body, there is a transmission device. The transmission device is respectively connected to input device A and input device B, and is also connected to the drill pipe. The box body is covered with an upper cover, and the two are connected by bolts. The bottom of the box body is connected to the bottom shell. The power source of the gearbox is input device A and input device B. These two input devices are usually connected to different power sources, which may be two sets of driving devices in the dual-power device 3 or other independent power supply equipment. Input device A and input device B transfer external power to the transmission device inside the gearbox. During the transfer process, the input devices will, according to the actual operation requirements, deliver power to the transmission device at a certain ratio and rhythm to ensure that the transmission device obtains stable and matching power input to meet the requirements for torque and rotational speed under different drilling conditions; the transmission device inside the gearbox body is the core component for realizing power conversion and transmission. The transmission device is usually composed of a series of components such as gears, shafts, and bearings. These components cooperate with each other and change the rotational speed and torque of the power through the meshing of gears. When input device A and input device B transfer power to the transmission device, the gears inside the transmission device will operate according to their own tooth ratios to achieve the speed-changing function. If it is necessary to increase the torque to cope with hard geological conditions, the transmission device will reduce the output rotational speed through a specific gear combination, thereby increasing the torque; conversely, if it is necessary to increase the drilling speed, the transmission device will adjust the gear combination to increase the output rotational speed and correspondingly reduce the torque. In this way, the transmission device can flexibly adjust the output power parameters according to the actual drilling operation needs to ensure that the drill pipe can work efficiently and stably in different geological environments; the power after being speed-changed by the transmission device is finally transferred to the drill pipe connected to the gearbox. The drill pipe is the component that directly acts on the bottom of the well for drilling operations. The power output by the gearbox drives the drill pipe to rotate, thereby realizing the crushing and drilling of the rock. In this process, the gearbox not only provides rotational power for the drill pipe but also ensures that the rotational speed and torque of the drill pipe can meet the requirements of the drilling process. For example, when drilling in a relatively soft formation, a higher rotational speed and relatively lower torque are required. The gearbox provides appropriate power for the drill pipe through the adjustment of the transmission device; while when drilling in a hard rock formation, the gearbox will increase the output torque and reduce the rotational speed to ensure that the drill pipe can effectively break the rock and smoothly carry out the drilling operation; the box body, upper cover, and bottom shell of the gearbox together form a closed structure, providing protection and support for the internal transmission device, input device, and other components. The upper cover of the box body is connected to the box body by bolts. This connection method is convenient for disassembly and installation when it is necessary to maintain or repair the internal components of the gearbox. The upper cover and the bottom shell can effectively prevent external dust, impurities, etc. from entering the inside of the gearbox, avoiding these foreign objects from causing wear or damage to the transmission components and affecting the normal operation of the gearbox. At the same time, the box body and the bottom shell can also withstand a certain amount of external force, providing a stable installation foundation for the internal components to ensure that the gearbox can still operate reliably in a complex working environment.In addition, a sealing device may be installed between the box body and the bottom case, further enhancing the sealing performance of the gearbox, preventing lubricating oil from leaking, ensuring that the internal transmission components are always in a good lubricated state, reducing friction and wear, and improving the working efficiency and service life of the gearbox.

[0036] As a preferred technical solution, the slewing device includes a rotating body. A convex ring is provided on the rotating body and the connection between them is a fixed connection. A toothed disc is provided on the convex ring, and the toothed disc is connected to two sets of rotating devices. The rotating devices are fixed on a bushing through a fixing frame. The bushing and the convex ring are connected by a bearing. A connecting device is provided at each of the two ends of the rotating body, and a support device B and a support device A are respectively provided at the front and rear ends of the rotating body. The power of the slewing device usually comes from a gearbox. The output shaft of the gearbox is connected to the rotating body of the slewing device (not explicitly mentioned in the given text, but this connection exists in an actual top drive device). When the gearbox works, the torque it outputs drives the rotating body to rotate. The convex ring fixedly connected to the rotating body rotates synchronously, and the toothed disc on the convex ring also rotates together. The toothed disc is connected to two sets of rotating devices, and the rotation of the toothed disc drives the rotating devices to operate. The rotating device generally includes a motor and a speed reduction mechanism (not explicitly mentioned in the given text, but inferred from the perspective of achieving the function). The motor generates power, and after adjusting the speed and torque through the speed reduction mechanism, it is transmitted to the toothed disc to assist the rotating body to rotate more stably. And when encountering a large resistance, it provides additional torque support to enhance the working ability of the slewing device; the bushing and the convex ring are connected by a bearing, and this structural design is crucial. The bearing can reduce the friction between the convex ring and the bushing, making the convex ring rotate more smoothly. The rotating device is fixed on the bushing through a fixing frame, and the bushing provides a stable support structure for the rotating device and the entire slewing device. During the rotation of the rotating body, the bushing and the bearing work together to ensure that the rotating body can rotate stably around its own axis, reduce shaking and deviation, and ensure the stability and accuracy of the slewing device during operation. At the same time, the support device A and the support device B provided at the front and rear ends of the rotating body further enhance the stability of the rotating body. The support device can bear part of the axial and radial forces generated during the rotation of the rotating body, reduce the load on the bearing, improve the overall load-bearing capacity of the slewing device, and extend its service life. In actual drilling operations, the drill string may be subjected to forces from different directions. The support device A and the support device B can effectively disperse these forces, ensure the smooth rotation of the rotating body, and enable the drill string to accurately perform drilling operations; the connecting devices provided at both ends of the rotating body are used to connect different components. The front connecting device is usually connected to the drill pipe to transmit the rotational motion of the slewing device to the drill pipe, enabling the drill pipe to perform rotary drilling operations. The rear connecting device may be used to connect other auxiliary equipment, such as a back-up tong or to connect to other parts of the top drive device to achieve the coordinated operation of each component of the entire top drive device. During drilling operations, the rotation of the rotating body drives the drill pipe to rotate, and the drill bit on the drill pipe breaks the underground rock to achieve the drilling function. At the same time, the slewing device cooperates with components such as the back-up tong to ensure the stability and safety of the drill pipe when replacing the drill pipe or performing other operations. For example, when replacing the drill pipe, the back-up tong can fix the drill pipe to prevent it from rotating, and the slewing device assists in completing the disassembly and installation of the drill pipe.

[0037] As a preferred technical solution, the dual-power unit includes a gearbox equipped with two transmissions arranged axially symmetrically about the gearbox. The transmissions include a drive unit and a heat sink. The heat sink is connected to the drive unit at its top, and the output shaft of the drive unit passes through the heat sink and connects to the gearbox. The heat sink is then connected to the gearbox. The core of the dual-power unit is the two transmissions symmetrically arranged on the gearbox. The drive unit in each transmission unit is the source of power and typically consists of a high-performance motor. When the drive unit is powered on, the rotor inside the motor begins to rotate at high speed under the action of electromagnetic force, which in turn drives the output shaft. The output shaft of the drive unit passes through the heat sink and connects to the gearbox, transmitting the rotational power generated by the motor to the gearbox. Because the two transmission units are axially symmetrical about the gearbox, they can simultaneously and evenly input power to the gearbox, providing the gearbox with double the driving torque. This provides strong and stable power support for other components of the top drive unit (such as the gearbox and slewing unit), meeting the high torque and speed requirements of oil exploration and drilling operations. For example, when drilling into hard formations, high torque is required to drive the drill pipe and break the rock. The dual-power unit, with its double power output, ensures sufficient torque for the drill pipe to successfully complete the drilling task. The gearbox plays a key role in power coordination and distribution within the dual-power unit. It receives power input from two transmissions and, through a complex internal gear system, distributes it optimally to the connected equipment. The gear structure within the gearbox is meticulously designed to adjust the output speed and torque based on actual operational requirements. In some cases, reducing speed to increase torque is necessary, and the gearbox achieves this through a specific gear combination. In other cases, increasing speed requires switching to a different gear ratio to meet the speed requirements of the equipment. This flexible power coordination and distribution mechanism enables the dual-power unit to adapt to the diverse and complex operating conditions of oil exploration, ensuring efficient and stable operation of the top drive under diverse operating conditions. During operation, the conversion of electrical energy into mechanical energy generates a significant amount of heat. To ensure continuous and stable operation of the drive unit, each transmission unit is equipped with a heat dissipation device. The top of the heat sink is connected to the drive unit, fitting snugly against the drive unit's heat-generating areas, effectively absorbing the heat generated by the drive unit. The heat sink is also connected to the gearbox. This allows the heat sink to transfer some heat to the gearbox through contact, aiding heat dissipation through the gearbox's larger surface area. This connection also helps enhance the stability of the dual-power unit structure. The heat sink typically utilizes high-efficiency heat dissipation materials and structures, such as fins and fans (though not explicitly mentioned in the given text, they are common configurations for heat dissipation).The heat dissipation fins increase the heat dissipation area, enabling heat to be dissipated to the surrounding environment more quickly; the cooling fan further improves the heat dissipation efficiency by forcing air flow. Through the continuous operation of the heat dissipation device, the temperature of the driving device is controlled within a reasonable range, avoiding a decline in motor performance, shortening of lifespan or even damage due to excessive temperature, thus ensuring the reliability and stability of the dual power device and ensuring that it can continuously and stably provide power for the top drive device during long-term and high-load oil exploration operations.

[0038] An oil exploration top drive device control system includes a control core unit, a data acquisition module, a drive control module, a communication module, and a human-machine interface; the control core unit is respectively connected to the data acquisition module, the drive control module, the communication module, and the human-machine interface; the data acquisition module is connected to the trolley, double lifting ring device, gearbox, slewing device, and double power device of the top drive device through sensors, and is used to collect the operation data of each component and transmit it to the control core unit. The data acquisition module, as the "perceptual antenna" of the system, establishes connections with the key components of the top drive device through various sensors. For the trolley, a displacement sensor and a speed sensor respectively monitor its position and moving speed on the slide rail in real time. By collecting these data, the running track and motion state of the trolley can be accurately grasped; on the double lifting ring device, a tension sensor monitors the tension on the lifting ring, and an angle sensor detects the angle change of the lifting ring, providing a basis for judging the working state and safety of the double lifting ring device. At the gearbox part, a rotational speed sensor obtains the rotational speed of the internal transmission components, a torque sensor measures the transmitted torque, and a temperature sensor monitors the working temperature. These data reflect the power transmission efficiency and working stability of the gearbox. At the slewing device, an angle sensor and a rotational speed sensor respectively collect the rotation angle and speed of the slewing body to ensure precise control of the slewing action. For the double power device, a current sensor monitors the current of the drive device, and a temperature sensor monitors the temperature of the drive device and the heat dissipation device to understand the power output situation and heat dissipation effect. The data acquisition module converts the analog signals collected by these sensors into digital signals and transmits them to the control core unit in a high-speed and stable manner through a data transmission line; the control core unit is the "brain" of the entire control system. After receiving a large amount of operation data from the data acquisition module, it performs analysis and processing according to preset algorithms and logics. It will compare the real-time collected data with the preset standard parameters and safety thresholds. For example, it compares the actual speed of the trolley with the set constant moving speed to determine whether there is a speed anomaly; it compares the torque and temperature of the gearbox with the normal working range to determine whether its working state is normal. Once it is found that the data exceeds the normal range or there are abnormal fluctuations, the control core unit will quickly make a decision. It will generate corresponding control instructions according to the type and severity of the abnormal situation, and these instructions will be used to adjust the operation state of the equipment to ensure the safe and stable operation of the top drive device; the drive control module is responsible for receiving the control instructions issued by the control core unit and converting them into actual control actions to drive the components of the top drive device to work. If the control core unit detects that the speed of the trolley is lower than the set value, it will send an acceleration instruction to the drive control module. The drive control module then adjusts the motor drive signal of the transmission device, such as increasing the current of the motor or changing the frequency of the motor, so that the motor outputs a greater torque, thereby driving the trolley to accelerate and restoring it to the set speed.When the temperature of the dual-power device is too high, the control core unit instructs the drive control module to reduce the power of the drive device. The drive control module reduces the output power of the motor and the heat generation by adjusting the control parameters of the motor. At the same time, the drive control module enhances the heat dissipation capacity of the heat dissipation device, such as increasing the rotation speed of the heat dissipation fan to accelerate the heat dissipation, ensuring that the dual-power device operates within an appropriate temperature range; The communication module acts as an "information bridge" in the entire system. Using a specific communication protocol (such as PROFINET, etc.), it realizes data transmission between the control core unit and remote devices. It sends the data processed by the control core unit, such as the real-time operating status of each component of the top drive device, fault alarm information, etc., to the remote monitoring center or other relevant devices, facilitating the operator to remotely and real-time understand the device status. The communication module also receives control instructions from remote devices, such as instructions sent by remote operators to adjust the device operating parameters according to the on-site situation, and then transmits these instructions to the control core unit. The control core unit sends corresponding control signals to the drive control module according to the received instructions to achieve remote control of the top drive device, improving the convenience and flexibility of operation; The human-machine interface is the window for the operator to interact with the control system of the top drive device. Through various visual elements on the interface, such as the real-time data display area, operation buttons, charts, etc., the operator can intuitively obtain the operation information of the top drive device and issue control instructions. In the real-time data display area, the operator can see key data such as the position of the block, the torque of the gearbox, and the temperature of the dual-power device. When the device needs to be operated, the operator clicks the corresponding operation button, such as starting or stopping a certain component, adjusting the device operating parameters, etc. These operation instructions will be sent to the control core unit through the human-machine interface. After being processed by the control core unit, the feedback information will be displayed to the operator through the human-machine interface again, such as whether the operation is successfully executed, the update of the device status, etc., realizing two-way information interaction between the operator and the control system, facilitating the operator to monitor and control the top drive device.

[0039] As a preferred technical solution, the driving control module is connected to the transmission device, the dual-power device, and the slewing device of the top drive device, and drives and controls each power component according to the instructions of the control core unit; the communication module adopts the PROFINET communication protocol to realize the communication between the control core unit and the remote I / O module, the driller's console, the frequency converter A, and the frequency converter B; the human-machine interface includes an overall structure screen, a top drive system screen, a network topology screen, an auxiliary interface screen, an alarm record screen, a curve trend screen, an advanced management screen, and an exit system screen, which are used for operators to interact with the control system. The driving control module plays a key role in the entire control system of the top drive device, executing control instructions and driving the equipment to operate. It is like a precise executor, always ready to receive control instructions from the control core unit and quickly convert these instructions into practical control actions to drive the various components of the top drive device to work in an orderly manner. Taking the operation control of the block as an example, when the control core unit determines that the speed of the block is lower than the pre-set value based on the data fed back by the data acquisition module, it will immediately send an acceleration instruction to the driving control module. After receiving this instruction, the driving control module quickly and precisely adjusts the motor drive signal of the transmission device. Specifically, it may increase the motor current to enhance the electromagnetic force inside the motor, thereby outputting a larger torque; or it may adjust the motor speed by changing the motor frequency to make the motor output more powerful power. The ultimate goal of these adjustments is to drive the block to accelerate and enable it to quickly return to the set operating speed to ensure the overall operating rhythm of the top drive device. When the temperature of the dual-power device becomes too high due to long-term high-load operation or other reasons, the control core unit will also quickly respond and send an instruction to the driving control module to reduce the power of the driving device. After receiving the instruction, the driving control module reduces the output power of the motor by finely adjusting various control parameters of the motor. As a result, the heat generated by the motor during operation will be reduced accordingly. At the same time, the driving control module will also take measures to enhance the heat dissipation capacity of the heat dissipation device. For example, it will increase the speed of the heat dissipation fan to allow more cold air to quickly flow through the heat-generating components and accelerate the dissipation of heat. Through this series of operations, the driving control module ensures that the dual-power device always operates within a suitable temperature range, maintains its stable and efficient operating state, avoids failures caused by overheating, and ensures the continuous and reliable operation of the top drive device in the complex oil exploration operation environment.

[0040] As a preferred technical solution, the control core unit generates control instructions according to the data collected by the data acquisition module and the preset control strategy, and sends them to the drive control module to achieve feedback control of the top drive device. The control core unit, as the core hub of the entire control system, is like the "brain" of a human being and plays a crucial decision-making and regulatory role during the operation of the system. It continuously receives a large amount of operation data transmitted from the data acquisition module, which covers the real-time status information of each key component of the top drive device and is the key basis for the entire system to understand the operation of the equipment. After receiving the data, the control core unit will conduct in-depth and detailed analysis and processing of these data according to the pre-written and stored algorithms and logic programs. An important link in the analysis process is to accurately compare the real-time collected data with the pre-set standard parameters and safety thresholds. Taking the traveling block as an example, it will compare the actual moving speed of the traveling block with the uniformly moving speed set by the system to determine whether there is an abnormal speed of the traveling block. If the actual speed deviates from the set speed to a certain extent, it indicates that there is a problem with the operating state of the traveling block. For the gearbox, the control core unit will simultaneously monitor its torque and temperature data and compare them with the normal working range to determine whether the working state of the gearbox is normal. If the torque of the gearbox is too high or the temperature exceeds the normal range, this may mean that there are potential failure risks such as wear and overload inside the gearbox. Once the control core unit finds that some data exceeds the normal range or shows abnormal fluctuations during the data comparison process, it will quickly respond. The control core unit will quickly generate targeted control instructions according to the specific type of abnormal situation, such as speed abnormality, temperature abnormality or other parameter abnormalities, and the severity of the abnormality. These instructions are like the "commands" sent to each execution component of the system and will be sent to relevant units such as the drive control module, and then adjust the operating state of the equipment. In this way, the control core unit can timely correct the deviation during the operation of the equipment, avoid the occurrence or deterioration of potential failures, and thus ensure that the top drive device is always in a safe and stable operating state, guaranteeing the smooth progress of oil exploration operations.

[0041] As a preferred technical solution, the operator issues operation instructions through the human-machine interaction interface. After receiving the instructions, the control core unit controls the actions of each component of the top drive device through the drive control module. The human-machine interaction interface, as a key bridge for communication between the operator and the control system of the top drive device, provides a convenient and intuitive channel for their interaction. It integrates various visual elements, such as real-time data display areas, operation buttons, charts, etc., to build an information-rich and easy-to-operate interaction platform. On this interface, the real-time data display area is like a transparent "window", presenting the key operation information of the top drive device to the operator without reservation. The real-time position of the block, the torque value currently borne by the gearbox, the current temperature of the dual power device, etc., these data crucial for judging the operation state of the equipment are clearly displayed therein. The operator can quickly grasp the real-time dynamics of the equipment with just a glance, providing a strong basis for subsequent decision-making. The operation buttons are the "quick channels" for the operator to issue instructions to the control system. When the equipment needs to be controlled during actual operation, the operator only needs to click on the corresponding operation button to easily achieve precise control of the equipment. These operations cover key operations such as starting or stopping a certain component and adjusting the operation parameters of the equipment. Each click represents a clear operation instruction, which is quickly and accurately transmitted to the control core unit through the human-machine interaction interface. After receiving these instructions, the control core unit will immediately process them and send the processing results back in the form of feedback information. The human-machine interaction interface plays a key role again, intuitively displaying these feedback information to the operator, including whether the operation is successfully executed, the real-time update of the equipment status, etc. In this way, efficient and two-way information interaction is achieved between the operator and the control system. The operator can monitor the operation status of the top drive device in real time and adjust the control strategy in a timely manner according to the feedback, greatly facilitating the comprehensive monitoring and precise control of the top drive device, and significantly improving the efficiency and safety of the operation.

[0042] The specific advantages are as follows: In oil exploration operations, the coordinated operation of each component of the top drive device plays a decisive role in the smooth progress of the entire exploration process. The control system of the present invention, relying on its advanced sensor technology, intelligent algorithms, and high-speed data processing capabilities, realizes precise connection control of each component of the top drive device. In terms of the connection control between the block and the slide rail, high-precision displacement sensors and speed sensors collect the position and speed information of the block in real time, and transmit this data to the control core unit at the speed of milliseconds. The control core unit, according to the preset operating trajectory and accuracy requirements, through complex calculation and analysis, issues precise control instructions to the drive device. The drive device accurately adjusts the power output according to the instructions, so that the movement accuracy of the block on the slide rail is controlled within a very small error range, ensuring that the top drive device can quickly and accurately position in different operating scenarios. For the connection control between the dual power device and the gearbox, the system monitors various parameters in the power transmission process through torque sensors, speed sensors, and temperature sensors installed at key positions. Once abnormal fluctuations in torque, speed, or temperature are detected, the control core unit immediately activates the dynamic adjustment mechanism, precisely adjusting the output power and speed of the dual power device to ensure that the gearbox obtains stable and matching power input. In this process, the control core unit can complete the analysis and processing of a large amount of data in an instant, issue precise control instructions, and make the coordinated work between the dual power device and the gearbox reach the best state, effectively reducing the wear and failure risks of the equipment caused by power mismatch and extending the service life of the equipment. In the connection control between the slewing device and other components, angle sensors and encoders accurately monitor the rotation angle and speed of the slewing device. Whether it is the rapid rotation during drilling or the precise angle adjustment, the control core unit can calculate the best control strategy within microseconds according to the actual needs, and precisely control the movement of the slewing device through the drive control module to ensure its close cooperation with other components and achieve efficient and precise drilling operations. For example, during drilling operations in complex formations, the slewing device needs to frequently adjust the rotation speed and angle according to the formation conditions. The control system of the present invention can quickly respond and precisely control, making the drilling operation smoother, improving the verticality of the well and the smoothness of the wellbore, and laying a solid foundation for subsequent oil well production work. By realizing precise connection control of each component of the top drive device, the system can monitor the operating state of the equipment in real time and adjust the operating parameters of the equipment in a timely manner according to the monitoring data. When the operating state of a certain component is detected to be abnormal, the system will quickly issue an alarm and automatically adjust the operating parameters of the relevant components to ensure the overall stability of the equipment. This real-time monitoring and adjustment mechanism greatly improves the stability and reliability of the equipment operation and reduces the occurrence probability of equipment failures. In actual oil exploration operations, the top drive device using the control system of the present invention has a lower equipment failure rate and a longer continuous operation time compared with traditional top drive devices, effectively improving the efficiency and quality of oil exploration.For example, in an offshore oil exploration operation, due to the adoption of the control system of the present invention, the top drive device can still operate stably when facing complex geological conditions and harsh marine environments, successfully completing the drilling task. The exploration efficiency is improved compared with the past, and the exploration quality has also been significantly enhanced. The geological data obtained is more accurate and comprehensive, providing a more reliable basis for subsequent oil extraction.

[0043] At the oil exploration site, operators need to quickly and accurately control and manage the top drive device in a complex environment. The human-machine interaction interface of the present invention fully considers the needs of operators and designs an operation interface with rich functions, intuitive and easy to understand. The interface adopts a high-definition display screen and a simple and clear icon design, presenting various operating parameters of the equipment to the operators in an intuitive way. For example, key parameters such as the rotation speed, torque, and temperature of the top drive device are displayed in real time through a large dashboard, and the changes in the parameters are clearly visible through the dynamic display of colors and values; the graphical interface is used to show the operating status of each component of the equipment, with green indicating normal operation and red indicating a fault status, so that operators can quickly judge the overall operating condition of the equipment. To facilitate operators to perform operations, a series of operation buttons and shortcut menus are set on the human-machine interaction interface. These buttons and menus are reasonably arranged and easy to operate. Operators can easily complete various operations, such as starting or stopping the equipment, adjusting the equipment operating parameters, and switching monitoring screens, by touching the screen or using external input devices (such as a mouse, keyboard). At the same time, the interface also provides detailed operation guides and prompt information, so that even operators who are new to the equipment can familiarize themselves with the operation process and quickly get started in a short time. During the actual operation process, operators can intuitively and conveniently master the equipment operating status through the human-machine interaction interface and make decisions quickly. When the equipment has an abnormal situation, the interface will immediately pop up an alarm window and display detailed fault information and handling suggestions. Based on this information, operators can quickly take corresponding measures to handle it, avoiding equipment damage and production accidents caused by untimely fault handling. For example, during a drilling operation, the equipment suddenly had an abnormal increase in torque. The human-machine interaction interface immediately issued an alarm and prompted that it might be that the drill pipe encountered a hard obstacle. According to the prompt information, the operator quickly adjusted the operating parameters of the equipment, reduced the torque, avoided damage to the drill pipe, and ensured the smooth progress of the drilling operation. In addition, the human-machine interaction interface also has the functions of operation record and data analysis. The system will automatically record each operation of the operator and the operating data of the equipment. Operators can view the operation records and historical data at any time, conduct data analysis and summarize experience. Through the analysis of historical data, operators can discover potential problems existing in the equipment operation process, take preventive measures in advance, and improve the operation efficiency and reliability of the equipment. At the same time, the data analysis function can also provide a basis for the maintenance and management of the equipment, helping managers formulate more reasonable maintenance plans and equipment upgrade plans. Through the above function design, the human-machine interaction interface greatly reduces the work intensity of operators, improves the accuracy and safety of operations. In practical applications, compared with operators using traditional interfaces, the work efficiency of operators using the human-machine interaction interface of the present invention is increased by [X]%, and the operation error rate is reduced by [X]%, effectively ensuring the smooth progress of oil exploration operations.

[0044] In the field of oil exploration, stable communication between the control system and various devices is one of the key factors to ensure the normal operation of the top drive device. The communication module of the present invention adopts the PROFINET communication protocol, which provides reliable guarantee for the communication between the control system and various devices. The PROFINET communication protocol is a high-performance communication protocol based on industrial Ethernet, with the advantages of strong real-time performance, high transmission rate, good reliability, etc. The communication module of the present invention adopts an advanced network architecture and communication technology, giving full play to the advantages of the PROFINET communication protocol. In terms of hardware, the communication module adopts a high-performance network chip and a wiring design with strong anti-interference ability, ensuring stable signal transmission; in terms of software, it adopts an optimized communication algorithm and data verification mechanism to ensure the accuracy and integrity of data. Through the PROFINET communication protocol, the communication module can achieve high-speed and stable communication between the control system and various devices of the top drive device. During the data transmission process, the communication module transmits control instructions and device operation data at an extremely high rate, with extremely small data transmission delay, which can meet the requirements of real-time control. For example, when controlling the rotation speed and torque of the top drive device, the delay time from the control instruction sent by the control system to the device execution is only a few milliseconds, ensuring that the device can quickly respond to the control instruction and achieve precise control. At the same time, the PROFINET communication protocol has strong anti-interference ability and can operate stably in a complex industrial environment. At the oil exploration site, there are various electromagnetic interferences and noise interferences, which may affect the stability of communication. The communication module of the present invention effectively resists external interferences and ensures communication reliability by adopting measures such as shielding technology, filtering technology and redundant design. Even in an environment with strong electromagnetic interference, the communication module can ensure the accurate transmission of data, avoiding equipment out-of-control and production accidents caused by communication failures. In addition, the communication module also supports remote monitoring and operation functions. Through the PROFINET communication protocol, operators can, in the control center far from the oil exploration site, monitor the operation status of the top drive device in real time and perform remote operations on the device. This function not only improves the operation convenience, but also reduces the exposure risk of operators in a dangerous environment. For example, in deep-sea oil exploration operations, operators can, in the control center on land, control and manage the top drive device on the offshore platform through the remote monitoring and operation function, realizing remote operation and unattended operation, improving production efficiency and safety. In summary, the communication module adopting the PROFINET communication protocol ensures the stability and timeliness of communication between the control system and various devices, provides reliable guarantee for the remote monitoring and operation of the devices, and effectively improves the intelligent level and production efficiency of oil exploration operations.

[0045] In oil exploration operations, the maintenance and management of the top drive device are crucial for ensuring the normal operation of the equipment, extending the service life of the equipment, and reducing maintenance costs. The control system of the present invention has perfect self-checking, alarming, and fault diagnosis functions, providing strong support for the maintenance and management of the equipment.

[0046] The self-checking function of the system can automatically conduct a comprehensive inspection of each component and system when the equipment starts up and during operation. Before the equipment starts up, the system will conduct a power-on test on the hardware equipment (such as sensors, controllers, actuators, etc.) to check whether the equipment is working properly; conduct an integrity check on the software system (such as the operating system, control program, communication protocol, etc.) to ensure that the software system is not damaged or missing files. During the operation of the equipment, the system will regularly monitor the operating status of each component to check whether there are potential faults in the equipment. For example, the system will monitor the output data of the sensors in real time to determine whether the sensors are working properly; monitor the temperature and working voltage of the controller to ensure that the controller operates in a normal working environment. Through the self-checking function, the system can promptly detect problems existing in the equipment and take measures in advance to handle them, avoiding the occurrence and expansion of faults.

[0047] When a fault occurs in the equipment, the alarming function of the system will be immediately activated. The alarm system will send alarm signals to the operators through various means such as sound, light, and screen prompts, and display detailed fault information, including the fault type, fault location, fault occurrence time, etc. The operators can quickly understand the fault situation of the equipment based on the alarm information and take corresponding measures to handle it. At the same time, the alarm system can also send the fault information to the remote monitoring center through the communication module so that the management personnel can timely grasp the operating status of the equipment and arrange maintenance personnel for repair.

[0048] To help the operators quickly locate and eliminate faults, the system also has a powerful fault diagnosis function. The fault diagnosis system adopts advanced data analysis algorithms and fault models, and can automatically analyze the fault causes based on the operating data and fault phenomena of the equipment and provide corresponding fault elimination suggestions. For example, when a motor overload fault occurs in the equipment, the fault diagnosis system will analyze the reasons for the motor overload based on the data such as the current, speed, and temperature of the motor, which may be due to excessive load, motor fault, or control system fault, etc., and give corresponding solutions, such as checking whether the load is normal, repairing the motor, or adjusting the control system parameters, etc. Through the fault diagnosis function, the operators can quickly find the fault causes and take effective measures for repair, reducing the equipment downtime and improving the production efficiency.

[0049] In addition to the perfect self-check, alarm and fault diagnosis functions, the control system of the present invention also has a remote upgrade function. With the continuous development of technology and the change of application requirements, the control system needs to be continuously optimized and updated. Through the remote upgrade function, the management personnel can remotely update the software and firmware of the system without affecting the normal operation of the equipment. The upgrade process is simple and convenient. Only need to send the upgrade file to the control system of the equipment through the communication module, and the system will automatically complete the upgrade operation. The remote upgrade function can not only repair the vulnerabilities and problems existing in the system in time, improve the stability and security of the system, but also provide users with new functions and performance optimization, and extend the service life of the equipment.

[0050] Through the above functions, the control system of the present invention greatly improves the maintainability of the equipment and facilitates the maintenance and management of the equipment. In practical applications, for the top drive device using the control system of the present invention, compared with the traditional top drive device, the average maintenance time of the equipment is shortened, the maintenance cost is reduced, the service life of the equipment is extended, and the economic benefits and production efficiency of oil exploration operations are effectively improved.
