Description

An automated well workover device and its control method, equipment, medium and product

[0001] This application claims priority to Chinese Patent Application No. 202411463894.8, filed on October 21, 2024, entitled "An Automated Well Workover Device and Its Control Method, Equipment, Medium and Product", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of oil extraction equipment technology, and in particular to an automated well workover device and its control method, equipment, medium and product. Background Technology

[0003] The existing manual well-work hydraulic tongs operation process typically involves one or two operators simultaneously pulling the steel cable of the tongs to bring them to the wellhead position. They then manipulate the tongs' rotation lever or shift lever upwards or downwards to control clockwise and counterclockwise rotation, as well as switching between high and low gears. Clockwise rotation tightens the threads at the two tubing joints, thus engaging the tubing. Counterclockwise rotation loosens the threads at the tubing joints, thus unengaging the tubing.

[0004] Most oil wells are currently located at depths of approximately 2,000 to 4,000 meters, while the length of a single tubing is about 10 meters. Therefore, approximately 200 to 400 tubing sections are required for well operations. This necessitates the use of hydraulic workover tongs to connect and tighten these numerous tubing sections. A standard hydraulic workover tong weighs approximately 200-250 kilograms. Workers must continuously and repeatedly drag or operate the tongs, rotating them clockwise and counterclockwise, and switching between high and low gears, while ensuring that each section of tubing is tightened, loosened, and that there is no slippage or disengagement. This process is both physically demanding and unsafe.

[0005] Therefore, providing an automated well workover platform is essential to ensure the safety of personnel and equipment during the operation and to improve the efficiency of well workover operations. Summary of the Invention

[0006] The purpose of this application is to provide an automated well workover device and its control method, equipment, medium and product, which can realize automated well workover operations, reduce the safety risks to personnel and equipment, and improve the efficiency of well workover operations.

[0007] To achieve the above objectives, this application provides the following solution:

[0008] In a first aspect, this application provides an automated well workover device, comprising: a wellhead platform installed on the wellhead, pneumatic slips installed on the wellhead platform at the wellhead, a well workover hydraulic tongs installed on the wellhead platform, and a well workover hydraulic tongs drive module.

[0009] The wellhead platform provides an installation platform for pneumatic slips, workover hydraulic tongs, and workover hydraulic tong drive modules. Pneumatic slips are used to secure tubing and prevent it from falling into the well. The workover hydraulic tong drive module is fixed to the wellhead platform via a bracket base and is used to push the workover hydraulic tongs closer to or further away from the wellhead. The workover hydraulic tongs are used to automatically engage or disengage the upper and lower tubing at the wellhead according to preset rotation direction, rotation speed, number of rotations, and rotation torque after approaching the wellhead.

[0010] Optionally, the well workover hydraulic tongs are equipped with a high / low gear switching button; the high / low gear switching button is used to manually switch the rotation speed of the well workover hydraulic tongs to low or high gear, and the rotation speed of the well workover hydraulic tongs is low gear by default.

[0011] Optionally, the well workover hydraulic tongs are equipped with a sensor module; the sensor module is used to detect the real-time rotational torque and number of rotations of the well workover hydraulic tongs.

[0012] Optionally, it also includes: a remote control module; the remote control module is located at a position far from the wellhead and is connected to the workover hydraulic tongs and the workover hydraulic tongs drive module via signals. The remote control module is used to automatically control the workover hydraulic tongs drive module to push the workover hydraulic tongs closer to or away from the wellhead according to the functions selected by the user, and after the workover hydraulic tongs approach the wellhead, it automatically performs the upper and lower tubing at the wellhead to engage or disengage according to the preset rotation direction, rotation speed, number of rotations and rotation torque.

[0013] Optionally, the remote control module provides users with selectable functions including: one-click engagement, one-click disengagement, forward movement of the hydraulic tongs, backward movement of the hydraulic tongs, forward rotation of the hydraulic tongs, reverse rotation of the hydraulic tongs, high / low gear switching of the hydraulic tongs, and emergency stop.

[0014] Optionally, the forward, backward, forward, reverse, and high / low gear switching functions of the workover hydraulic tongs have higher priority than the one-button hook-on and one-button hook-off functions; the emergency stop function has higher priority than the forward, backward, forward, reverse, and high / low gear switching functions of the workover hydraulic tongs.

[0015] Secondly, this application provides a control method for an automated well workover device, comprising the following steps:

[0016] When it is necessary to perform a workover or uncoupling operation, the workover hydraulic tongs are pushed close to the wellhead using the workover hydraulic tongs drive module; at the wellhead, the tubing is secured with pneumatic slips to prevent the tubing from falling into the well.

[0017] After the hydraulic tongs approach the wellhead, they are used to perform coupling or uncoupling operations on the upper and lower tubing at the wellhead according to the preset rotation direction, rotation speed, number of rotations and rotation torque.

[0018] After completing the attaching or unattaching operation, the hydraulic tongs are moved away from the wellhead by the hydraulic tongs drive module.

[0019] Thirdly, this application provides a computer device, including: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the control method for the automated well workover device described above.

[0023] This application provides an automated well workover device and its control method, equipment, medium, and product. In the automated well workover device, a wellhead platform is provided at the wellhead to house pneumatic slips, hydraulic tongs, and a hydraulic tongs drive module. Pneumatic slips secure the tubing to prevent it from falling into the well. The hydraulic tongs drive module moves the hydraulic tongs closer to or away from the wellhead. After the hydraulic tongs approach the wellhead, they automatically engage or disengage the upper and lower tubing sections at the wellhead according to preset rotation direction, speed, number of rotations, and torque. This application integrates the hydraulic tongs and drive module's related mechanical structures onto the wellhead platform, simplifying the modification process. It is applicable to most manual hydraulic tongs and ordinary platform modifications in the field. The drive module moves the hydraulic tongs closer to and away from the wellhead, replacing the traditional manual dragging method, thus achieving automated well workover operations. This reduces safety risks to personnel and equipment while improving the efficiency of well workover operations. Attached Figure Description

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] This application provides an automated well workover device, as shown in Figure 1. The automated well workover device includes: a wellhead platform mounted on the wellhead, pneumatic slips mounted on the wellhead platform at the wellhead, a hydraulic workover tongs mounted on the wellhead platform, and a hydraulic workover tongs drive module. The hydraulic workover tongs drive module is a hydraulic cylinder or liquid cylinder drive mechanism.

[0039] The wellhead platform provides an installation platform for pneumatic slips, workover hydraulic tongs, and workover hydraulic tong drive modules. Pneumatic slips are used to secure tubing and prevent it from falling into the well. The workover hydraulic tong drive module is fixed to the wellhead platform via a bracket base and is used to push the workover hydraulic tongs closer to or further away from the wellhead. The workover hydraulic tongs are used to automatically engage or disengage the upper and lower tubing at the wellhead according to preset rotation direction, rotation speed, number of rotations, and rotation torque after approaching the wellhead.

[0040] In an exemplary embodiment, an automated well workover device is provided, as shown in Figures 2-4, which are left, front, and top views of the automated well workover device, respectively. In this embodiment, the automated well workover device includes a wellhead platform. In addition to the hydraulic workover tongs and pneumatic slips, the wellhead platform also has an oil collection port, retaining the fluid collection and oil collection functions of the wellhead platform. As shown in the side view of the hydraulic workover tongs and its drive module in Figure 5, it can be seen that when the hydraulic workover tongs drive module extends, the hydraulic workover tongs body moves towards the wellhead, and when the hydraulic workover tongs drive module retracts, the hydraulic workover tongs body moves away from the wellhead.

[0041] In one exemplary embodiment, the well workover hydraulic tongs are provided with a high / low gear switching button; the high / low gear switching button is used to manually switch the rotation speed of the well workover hydraulic tongs to low or high gear, and the rotation speed of the well workover hydraulic tongs is low gear by default.

[0042] In one exemplary embodiment, the well-workover hydraulic tongs are equipped with a sensor module; in one embodiment, the sensor module includes sensors such as a rotation count sensor and a pressure detection sensor. The sensor module is used to detect the real-time rotational torque and rotation count of the well-workover hydraulic tongs.

[0043] To ensure operator safety, the automated well workover device also includes a remote control module. The remote control module is located away from the wellhead and is connected to the well workover hydraulic tongs and the well workover hydraulic tongs drive module via signals. The remote control module is used to automatically control the well workover hydraulic tongs drive module to push the well workover hydraulic tongs closer to or away from the wellhead according to the functions selected by the user. After the well workover hydraulic tongs approach the wellhead, it automatically performs the upper and lower tubing connection or disconnection operation at the wellhead according to the preset rotation direction, rotation speed, number of rotations and rotation torque.

[0044] In one exemplary embodiment, the remote control module provides users with selectable functions including: one-click snap-on function, one-click unsnap function, well workover hydraulic tongs forward function, well workover hydraulic tongs backward function, well workover hydraulic tongs forward rotation function, well workover hydraulic tongs reverse rotation function, well workover hydraulic tongs high / low gear switching function, and emergency stop function.

[0045] Figure 6 shows the operation panel of the remote control module, including a display screen located in the center of the top of the operation panel, and various function knobs below the display screen, such as: power switch button, emergency stop button, one-click buckling knob, one-click unbuckle knob, high / low gear switching knob, hydraulic clamp forward / reverse knob, and hydraulic clamp forward / backward knob; the display screen mainly shows the main page, manual page, and settings page.

[0046] The main page, as shown in Figure 7, displays the current torque (percentage), current torque value, current number of revolutions, current pressure, and virtual buttons for one-click buckling, one-click unbuckle, and low-speed hydraulic clamp. These virtual buttons are used when the physical buttons on the control panel malfunction. The manual page, as shown in Figure 8, displays virtual buttons for pneumatic slip opening, hydraulic clamp forward, hydraulic clamp backward, hydraulic clamp forward rotation, and hydraulic clamp reverse rotation. The PLC's input / output signals (I / O) are displayed on the right side, showing their on / off status on the touchscreen for easy troubleshooting. The settings page, as shown in Figure 9, displays settings for buckle shift revolutions, buckle stop revolutions, buckle shift revolutions, buckle stop revolutions, buckle stop pressure, hydraulic clamp forward time, hydraulic clamp backward time, hydraulic clamp pressure coefficient, and hydraulic clamp pressure compensation.

[0047] Specifically, the one-button engagement process is as follows: When the operator turns the one-button engagement knob, the hydraulic cylinder controlling the extension of the workover hydraulic tongs extends, and the workover hydraulic tongs body moves towards the wellhead. After the workover hydraulic tongs reach the desired position, they automatically rotate clockwise at a low speed to the set engagement shift number of turns. After reaching the set engagement shift number of turns, they automatically switch to a high speed and continue rotating. When the workover hydraulic tongs reach the engagement stop number of turns or the engagement stop pressure, they automatically stop rotating. After stopping, they automatically rotate counterclockwise to center (i.e., the hydraulic tong jaws are centered; the hydraulic tong jaws are similar to a C-groove for easy tubing entry and exit). After the workover hydraulic tongs have completed the counterclockwise centering, the hydraulic cylinder controlling the extension of the workover hydraulic tongs retracts, and the workover hydraulic tongs move away from the wellhead. After the workover hydraulic tongs have retracted, the one-button engagement action is complete.

[0048] Hydraulic tongs uncoupling action: When the operator turns the one-button uncoupling knob, the hydraulic cylinder controlling the advance and retreat of the workover hydraulic tongs extends, and the workover hydraulic tongs move towards the wellhead. After the workover hydraulic tongs have advanced to the designated position, they automatically rotate counterclockwise at a low speed to the set number of uncoupling shifts. After rotating to the set number of uncoupling shifts, they automatically switch to a high speed to continue rotating. When the workover hydraulic tongs have rotated to the uncoupling stop rotation number, they automatically stop rotating. After stopping, they automatically rotate clockwise to center. After the workover hydraulic tongs have completed centering, the hydraulic cylinder controlling the advance and retreat of the hydraulic tongs retracts, and the workover hydraulic tongs move away from the wellhead. After the workover hydraulic tongs have retracted, the one-button uncoupling action is completed.

[0049] Among the functions provided by the remote control module, the following functions have higher priority than the one-key hook-on and one-key unhooking functions: the forward movement of the workover hydraulic tongs, the backward movement of the workover hydraulic tongs, the forward rotation of the workover hydraulic tongs, the reverse rotation of the workover hydraulic tongs, and the high / low gear switching function. The emergency stop function has higher priority than the following functions: the forward movement of the workover hydraulic tongs, the backward movement of the workover hydraulic tongs, the forward rotation of the workover hydraulic tongs, the reverse rotation of the workover hydraulic tongs, and the high / low gear switching function.

[0050] Hydraulic clamp forward / backward: When the operator turns the knob, the hydraulic clamp moves forward or backward. Releasing the knob immediately stops the forward or backward movement. Hydraulic clamp forward / reverse: When the operator turns the knob, the hydraulic clamp rotates forward or backward. Releasing the knob immediately stops the forward or reverse movement. Hydraulic clamp high / low gear: The hydraulic clamp defaults to low gear. Turning the knob switches the hydraulic clamp to high gear. Emergency stop: Pressing the emergency stop button when the operator moves any mechanism on the platform stops all mechanisms from moving (this may cause mechanical or equipment failure, damage, or personnel interference or injury). When the system is performing one-key fastening or one-key unfastening actions, turning the hydraulic clamp forward / backward or forward / reverse will automatically stop the linkage action and reset the linkage logic. The hydraulic clamp will follow the operator's actions and stop when the operator releases the knob (the one-key linkage logic can be interrupted by the emergency stop and manual knob for convenient operation).

[0051] In another exemplary embodiment, as shown in FIG10, a control method for an automated well workover device is provided, comprising the following steps:

[0052] A1. When it is necessary to perform a workover or unworking operation, the workover hydraulic tongs are pushed close to the wellhead using the workover hydraulic tongs drive module; at the wellhead, the tubing is secured with pneumatic slips to prevent the tubing from falling into the well.

[0053] A2. After the hydraulic tongs approach the wellhead, use the hydraulic tongs to perform the coupling or uncoupling operation on the upper and lower tubing at the wellhead according to the preset rotation direction, rotation speed, number of rotations and rotation torque.

[0054] A3. After completing the workover or unworking operation, the workover hydraulic tongs are driven away from the wellhead by the workover hydraulic tongs drive module.

[0055] The proposed solution integrates the mechanical structure of a standard workover hydraulic tong onto a wellhead platform, simplifying the modification process. The hydraulic tong mechanism and control box are separate and modular, making it suitable for most manual workover hydraulic tongs and standard platform modifications in the field. The coupling and uncoupling actions are program-controlled, eliminating the need for manual operation and reducing worker workload while significantly improving safety. During operation, sensors detect hydraulic tong torque and the number of coupling / uncoupling turns, accurately controlling the coupling / uncoupling cycle of individual tubing sections through program control, effectively improving operational efficiency. The process parameters of the workover hydraulic tong coupling / uncoupling actions are digitized and can be copied to a USB drive for analyzing parameter trend curves and other actual data, facilitating subsequent process improvement and optimization. The integrated pneumatic slips, workover hydraulic tongs, and wellhead platform facilitate installation and transportation, enabling fluid and oil collection and application at wellheads of varying heights in the field.
