Description

Technical Field

[0001] This invention relates to the field of coiled tubing equipment technology, specifically to an injection head adjustment device and adjustment method. Background Technology

[0002] In traditional coiled tubing installation methods, the injection head is a key piece of equipment for clamping the tubing. Related technologies typically use a crane to suspend the injection head assembly, with tension ropes positioned on both sides of the injection head's gooseneck. The ends of these ropes are fixed to the ground via anchors or counterweights. This method is susceptible to periodic changes in the tension of the coiled tubing rollers and the influence of wind, causing the injection head and associated well control equipment to tilt relative to the wellhead. This requires manual adjustment of the tension ropes and the crane boom angle to restore the head to its original position, resulting in slow response, poor positioning accuracy, and safety hazards associated with working at height. Summary of the Invention

[0003] This invention provides an injection head adjustment device and method to solve the problem that the injection head is easily tilted by external forces and the response to manual adjustment is lag.

[0004] In a first aspect, the present invention provides an injection head adjustment device, comprising: Support frame, the support frame is adapted to support the injection head, the injection head is adapted to connect to the well control assembly, the support frame includes: support; The telescopic component is hinged to the bracket at one end. The support arm has one end hinged to the bracket and the other end hinged to the telescopic component away from the bracket. The telescopic arm is slidably mounted at the end of the support arm away from the bracket, and the injection head is connected to the end of the telescopic arm away from the support arm. The telescopic arm is adapted to slide along the support arm to adjust the position of the injection head in the x and z directions, and the telescopic component is adapted to adjust the angle between the support arm and the xy plane by extending and retracting.

[0005] Beneficial effects: The hinged connection between the bracket, telescopic components, support arm, and telescopic arm allows the injection head to be adjusted in both the x and z directions. Using a support frame instead of the crane and tension rope fixing method used in related technologies reduces the injection head's swaying and solves the problems of insufficient geometric constraint and susceptibility to tilting due to tubing tension and wind in those technologies. The support frame provides stable mechanical support for the injection head, structurally preventing misalignment of the sealing surface caused by injection head tilt, which could lead to blowout preventer leaks, wellhead overturning, and other safety accidents. Furthermore, the mechanized adjustment method replaces manual adjustment of the boom and tension ropes, improving the response speed and operational efficiency of injection head adjustment.

[0006] In one alternative embodiment, the end of the telescopic arm away from the support arm is provided with a slide rail, which extends along the y-direction, and the injection head is slidably mounted on the slide rail via a slider.

[0007] Beneficial effects: By sliding the injection head onto the slide rail, the position of the injection head in the y-direction can be adjusted, further adjusting the alignment accuracy between the injection head and the wellhead, and ensuring the safety and stability of coiled tubing construction.

[0008] In one alternative embodiment, the bracket includes a first frame and a second frame, a telescopic member is hinged to the first frame, a support arm is hinged to the second frame, and a guide rail extends along the x-direction. The first frame and the second frame are slidably disposed on the guide rail, or only the first frame is slidably disposed on the guide rail, or only the second frame is slidably disposed on the guide rail.

[0009] Beneficial effects: At least one of the first and second frames is slidably mounted on the guide rail, allowing adjustment of the positions of the support arm and telescopic component to further correct the spatial position of the injection head and align it with the wellhead. By adjusting the positions of the first and second frames on the slide rail, fine-tuning of the injection head position can be achieved. Compared to manually adjusting the tension rope, this not only reduces the workload for construction workers but also avoids problems such as injection head tilting and sealing surface misalignment caused by the lag and insufficient precision of manual tension rope adjustment, further ensuring construction stability and safety.

[0010] The telescopic component can rotate along its hinge point with the first frame, and the support arm can rotate along its hinge point with the second frame; the connection between the telescopic component and the support arm is detachable. The support arm and telescopic component can be rotated to fold and store the device, as shown below. Figure 11 and Figure 12 As shown, the overall space of the folded support frame is greatly reduced, which facilitates the separate transportation of the support frame or its transportation with the well control skid, thus improving the portability of the lifting device.

[0011] In one alternative embodiment, the telescopic arm is sleeved inside the support arm, and the telescopic arm is provided with a plurality of through holes spaced apart along its length. The through holes are adapted to be inserted into the connector to fix the sliding length of the telescopic arm relative to the support arm.

[0012] Beneficial effects: The telescopic boom is fitted inside the support arm, and the sliding length of the telescopic boom is fixed through the interlocking of the spaced through holes and the connectors. This ensures reliable locking of the injection head's height adjustment in the z-direction, guaranteeing that the injection head remains stable after reaching the target height and preventing height deviation caused by telescopic boom sliding during operation. This improves the overall structural stability of the device. At the same time, the multiple spaced through holes enable multi-level adjustment of the injection head's height in the z-direction, adapting to the different requirements of injection head height for different well depths and construction conditions, thus improving the device's adaptability. Furthermore, the connector fixing method is simple to operate and reliable in locking, enabling rapid height adjustment and fixing of the injection head during construction, effectively improving the efficiency of height adjustment during wellhead preparation and operation.

[0013] In one alternative implementation, the well control component includes: Blowout preventer, the blowout preventer is located below the injection head; Also includes: The transmitter is located at the injection head; Feedback unit, located on the blowout preventer, is adapted to receive signals from the transmitter.

[0014] Beneficial effects: By setting a transmitter in the injection head and a feedback device in the blowout preventer, the feedback device can receive signals from the transmitter in real time and monitor whether the injection head and the blowout preventer are aligned, thus providing a reliable signal basis for adjusting the injection head.

[0015] In one alternative implementation, a level is provided on the injection head, which is adapted to measure the horizontal state of the injection head.

[0016] Beneficial effects: By installing a level on the injection head to measure its horizontal state, it is possible to monitor in real time whether the injection head is aligned with the wellhead, promptly detect minor tilts caused by factors such as tubing tension and wind, and avoid safety issues such as misalignment of the sealing surface and leakage of the blowout preventer due to undetected tilts. At the same time, it provides reliable monitoring data support for the intelligent adjustment algorithm of the control center, and works with the drive system to achieve automatic alignment of the injection head, reduce manual intervention, improve the accuracy of injection head adjustment and the level of intelligence in operation, and ensure the safety and stability of the coiled tubing construction process.

[0017] In one alternative implementation, the slider and the injection head are connected by a connector.

[0018] Beneficial effects: By using connectors to fix the slider and injection head together, relative sway between the injection head and the telescopic arm is avoided. Compared with the crane suspension method used in related technologies, this improves the support stability of the injection head. At the same time, using connectors to detachably connect the slider and injection head allows for quick assembly and disassembly of the injection head and slider, facilitating subsequent individual inspection and maintenance of the injection head, slider, and slide rail.

[0019] In one alternative implementation, a tilt sensor is also included, which is disposed at one end of the support arm near the second frame and is adapted to detect the angle between the support arm and the xy plane.

[0020] The tilt sensor captures the tilt angle changes of the support arm in real time, providing monitoring data support for the drive system. When the tilt sensor detects that the tilt angle of the support arm exceeds the safety threshold, it can quickly trigger an early warning or emergency braking protection, effectively avoiding safety hazards such as injection head tilting and equipment instability caused by excessive tilt angle of the support arm.

[0021] Secondly, the present invention also provides an adjustment method applicable to the injection head adjustment device as described above, the adjustment method comprising: S1: Set the target height of the injection head, start the drive system that is electrically connected to the injection head adjustment device, and adjust the telescopic arm and telescopic component to make the injection head reach the target height; S2: Adjust the slider to adjust the position of the injection head in the y direction; S3: Detect the horizontal status of the injection head using a level. If it is not horizontal, adjust the first frame and / or the second frame until it is horizontal.

[0022] In one optional implementation, the operation begins after the injection head is level. During the operation, the level instrument monitors the level of the injection head in real time. If it is not level, it is adjusted through steps S1 to S3 until the operation is completed. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] In traditional coiled tubing installation methods, the injection head is a key piece of equipment for clamping the tubing. Related technologies typically use a crane to suspend the injection head assembly, with tension ropes positioned on both sides of the injection head's gooseneck. The ends of these ropes are fixed to the ground via anchors or counterweights. This method is susceptible to periodic changes in the tension of the coiled tubing drum windings and the influence of wind, causing the injection head and associated well control equipment to tilt relative to the wellhead. Manual adjustment of the tension ropes and the crane boom angle is required to restore it to its original position, resulting in slow response, poor positioning accuracy, and safety hazards associated with working at height. Therefore, there is an urgent need for a technical solution that enables automatic adjustment of the injection head and is adaptable to complex operating environments.

[0028] The following is combined Figures 1 to 13 The following describes embodiments of the present invention.

[0029] According to an embodiment of the present invention, in one aspect, an injection head adjustment device is provided, comprising: Support frame 1, support frame 1 is adapted to support injection head 2, injection head 2 is adapted to connect well control assembly 3, support frame 1 includes: Bracket 11; Telescopic component 12, one end of which is hinged to bracket 11; Support arm 13, one end of support arm 13 is hinged to bracket 11, and the other end is hinged to the end of telescopic member 12 away from bracket 11; Telescopic arm 14 is slidably disposed at the end of support arm 13 away from bracket 11, and injection head 2 is connected to the end of telescopic arm 14 away from support arm 13; telescopic arm 14 is adapted to slide along support arm 13 to adjust the position of injection head 2 in x and z directions, and telescopic member 12 is adapted to adjust the angle between support arm 13 and xy plane by telescopic extension.

[0030] It should be noted that in this invention, the z-direction is the height direction of the injection head adjustment device, the x-direction is the extension direction of the guide rail 51 in the horizontal plane, and the y-direction is the extension direction of the slide rail 42. The x, y, and z directions are orthogonal to each other, forming a spatial coordinate system suitable for wellhead construction.

[0031] Optionally, the telescopic component 12 can be a hydraulic cylinder, an electric push cylinder, or a pneumatic cylinder, preferably a hydraulic cylinder, to meet the high load adjustment requirements of the construction scenario.

[0032] Beneficial effects: The hinged connection between the bracket 11, telescopic component 12, support arm 13, and telescopic arm 14 allows the injection head 2 to be adjusted in both the x and z directions. Using the support frame 1 instead of the crane and tension rope fixing method used in related technologies prevents the injection head 2 from swaying, thus solving the problems of insufficient geometric constraint and susceptibility to tilting due to tubing tension and wind in related technologies. The support frame 1 provides stable mechanical support for the injection head 2, structurally preventing misalignment of the sealing surface caused by tilting of the injection head 2, which could lead to blowout preventer 32 leakage, wellhead overturning, and other safety accidents. Furthermore, the mechanized adjustment method replaces manual adjustment of the boom and tension ropes, improving the response speed and operational efficiency of the injection head 2 adjustment.

[0033] In one embodiment, the end of the telescopic arm 14 away from the support arm 13 is provided with a slide rail 42, which extends along the y direction, and the injection head 2 is slidably disposed on the slide rail 42 via a slider 41.

[0034] Beneficial effects: By sliding the injection head 2 onto the slide rail 42, the position of the injection head 2 in the y direction can be adjusted, further adjusting the alignment accuracy between the injection head 2 and the wellhead, and ensuring the safety and stability of coiled tubing construction.

[0035] In one embodiment, the bracket 11 includes a first frame 111 and a second frame 112, a telescopic member 12 is hinged to the first frame 111, a support arm 13 is hinged to the second frame 112, and a guide rail 51 extends in the x-direction. The first frame 111 and the second frame 112 are slidably disposed on the guide rail 51, or only the first frame 111 is slidably disposed on the guide rail 51, or only the second frame 112 is slidably disposed on the guide rail 51.

[0036] like Figure 3 , Figure 4 and Figure 8 As shown, the first frame 111 and the second frame 112 are slidably mounted on the guide rail 51 via the guide block 52. The guide block 52 can slide on the guide rail 51 to change the position of the first frame 111 or the second frame 112, thereby adjusting the support arm 13 and the telescopic component 12.

[0037] Beneficial effects: At least one of the first frame 111 and the second frame 112 is slidably mounted on the guide rail 51, allowing adjustment of the positions of the support arm 13 and the telescopic component 12 to further correct the spatial position of the injection head 2, ensuring alignment between the injection head 2 and the wellhead. By adjusting the positions of the first frame 111 and the second frame 112 on the slide rail 42, fine-tuning of the injection head 2's position can be achieved. Compared to manually adjusting the tension rope, this not only reduces the workload for construction workers but also avoids problems such as tilting of the injection head 2 and misalignment of the sealing surface caused by the lag and insufficient adjustment precision of manual tension rope adjustment, further ensuring construction stability and safety.

[0038] The telescopic component 12 can rotate along its hinge point with the first frame 111, and the support arm 13 can rotate along its hinge point with the second frame 112. The connection between the telescopic component 12 and the support arm 13 is detachable. The support arm 13 and the telescopic component 12 can be rotated to complete the folding and storage process, such as... Figure 11 and Figure 12 As shown, the overall space of the folded support frame 1 is greatly reduced, which facilitates the separate transportation of the support frame 1 or its transportation together with the well control skid 8, thereby improving the portability of the lifting device.

[0039] In one embodiment, the telescopic arm 14 is sleeved inside the support arm 13, and the telescopic arm 14 is provided with a plurality of through holes 141 at intervals along the length direction. The through holes 141 are adapted to be inserted into the connector 142 to fix the sliding length of the telescopic arm 14 relative to the support arm 13.

[0040] Beneficial effects: The telescopic arm 14 is fitted inside the support arm 13, and the sliding length of the telescopic arm 14 is fixed by the insertion and cooperation of the spaced through holes 141 and the plug-in parts 142. This ensures that the height adjustment of the injection head 2 in the z-direction is reliably lockable, ensuring that the injection head 2 remains stable after reaching the target height. This avoids height deviation caused by the sliding of the telescopic arm 14 during operation, thus improving the overall structural stability of the device. At the same time, the multiple spaced through holes 141 enable multi-level adjustment of the height of the injection head 2 in the z-direction, which can adapt to the different requirements of the height of the injection head 2 for different well depths and different construction conditions, improving the adaptability of the device. Furthermore, the fixing method of the plug-in parts 142 is simple to operate and reliable in locking, which can quickly complete the height adjustment and fixing of the injection head 2 during construction, effectively improving the efficiency of height adjustment during wellhead preparation and operation.

[0041] In one embodiment, such as Figure 6 and Figure 7 As shown, well control component 3 includes: A blowout preventer 31 is disposed below the injection head 2 along the height direction; The blowout preventer 32 is connected to the end of the blowout preventer box 31 away from the injection head 2. The blowout preventer 32 has different length specifications and can be spliced ​​and combined by multiple sections of the blowout preventer 32 to form a suitable length to adapt to the height requirements of different well sites and different construction conditions, so as to stably connect the injection head 2 and the blowout preventer 33. Blowout preventer 33, which is located below injection head 2; Also includes: Emitter 61, which is disposed at injection head 2; Feedback unit 62 is disposed on the blowout preventer 33 and is adapted to receive signals from transmitter 61; like Figure 11 and Figure 12 As shown, it also includes a well control skid 8, which is used to house the well control components 3, such as the blowout preventer box 31, blowout preventer pipe 32, and blowout preventer 33. The well control components 3 can be housed in the well control skid 8 to achieve overall transportation of the well control components 3. The well control skid 8 can also be placed under the support 11 to elevate the support 11 and further expand the height range of the injection head 2.

[0042] Optionally, the transmitter 61 is an infrared transmitter 61; the feedback unit 62 is an infrared feedback unit 62. The infrared transmitter 61 can continuously emit infrared light signals, and the infrared feedback unit 62 has the function of receiving and identifying infrared signals. It can capture the infrared light signals emitted by the infrared transmitter 61 and determine the relative positional relationship between the infrared transmitter 61 and the infrared feedback unit 62 based on the signal reception strength and reception position.

[0043] By setting a transmitter 61 in the injection head 2 and a feedback device 62 in the blowout preventer 33, the feedback device 62 can receive the signal from the transmitter 61 in real time and monitor whether the injection head 2 and the blowout preventer 33 are aligned in real time, thus providing a reliable signal basis for the adjustment of the injection head 2.

[0044] In one embodiment, a level 63 is provided on the injection head 2, which is adapted to measure the horizontal state of the injection head 2.

[0045] Beneficial effects: Optionally, the level 63 may be an electronic level 63. The electronic level 63 can accurately and in real time detect changes in the horizontal tilt angle of the injection head 2, convert the detected horizontal state data into electrical signals and feed them back to the control center, providing direct and quantitative accurate data for the straightening and adjustment of the injection head 2.

[0046] By installing a level 63 on the injection head 2 to measure its horizontal state, it is possible to monitor in real time whether the injection head 2 is aligned with the wellhead, promptly detect minor tilts caused by factors such as tubing tension and wind force, and avoid safety issues such as misalignment of the sealing surface and leakage of the blowout preventer 32 due to undetected tilts. At the same time, it provides reliable monitoring data support for the intelligent adjustment algorithm of the control center, and works with the drive system to achieve automatic alignment of the injection head 2, reduce manual intervention, improve the accuracy of the injection head 2 adjustment and the level of intelligence of the operation, and ensure the safety and stability of the coiled tubing construction process.

[0047] In one embodiment, the slider 41 and the injection head 2 are connected by a connector 21.

[0048] Beneficial effects: Optionally, the connector 21 is a locking pin. The locking pin is inserted and locked by passing it through the corresponding pin holes of the slider 41 and the injection head 2 in sequence, so as to achieve a firm connection between the slider 41 and the injection head 2.

[0049] By using connector 21 to connect and fix slider 41 and injection head 2, relative sway between injection head 2 and telescopic arm 14 is avoided. Compared with the crane suspension method used in related technologies, this improves the support stability of injection head 2. At the same time, using connector 21 to detachably connect slider 41 and injection head 2 allows for quick assembly and disassembly of injection head 2 and slider 41, facilitating individual inspection and maintenance of injection head 2, slider 41 and slide rail 42 in the future.

[0050] In one embodiment, an angle sensor 64 is also included. The angle sensor 64 is disposed at one end of the support arm 13 near the second frame 112. The angle sensor 64 is adapted to detect the angle between the support arm 13 and the xy plane.

[0051] The tilt sensor 64 captures the tilt angle changes of the support arm 13 in real time, providing monitoring data support for the drive system. When the tilt sensor 64 detects that the tilt angle of the support arm 13 exceeds the safety threshold, it can quickly trigger an early warning or emergency braking protection, effectively avoiding safety hazards such as tilting of the injection head 2 and equipment instability caused by excessive tilt angle of the support arm 13.

[0052] In one embodiment, the system also includes a maintenance ladder assembly, which includes a fixed ladder 71 and a telescopic ladder 72. The fixed ladder 71 is fixedly mounted on the support arm 13, and the telescopic ladder 72 is slidably mounted on the fixed ladder 71. The telescopic ladder 72 can extend and retract synchronously with the telescopic arm 14.

[0053] like Figure 1As shown, the support arm 13 and the telescopic arm 14 can form a stable rigid support for the maintenance ladder assembly 7. Compared with the use of the tension rope to stabilize the injection head 2 in related technologies, the equipment is prone to shaking, resulting in a lack of stable operating support for maintenance. In this embodiment, maintenance personnel can rely on the stable maintenance ladder assembly 7 to carry out operations, making the maintenance process safer and more convenient, and greatly reducing the safety hazards of high-altitude maintenance.

[0054] According to an embodiment of the present invention, in another aspect, an adjustment method is also provided, applicable to the injection head adjustment device as described above, the adjustment method comprising: S1: Set the target height of injection head 2, such as Figure 4 As shown, the drive system is electrically connected to the injection head adjustment device through the control interface 9. The drive system electrically connected to the injection head adjustment device is started, and the injection head 2 is made to reach the target height by adjusting the telescopic arm 14 and the telescopic component 12. S2: Adjust slider 41 to adjust the position of injection head 2 in the y direction so that injection head 2 is initially aligned with the wellhead; when adjusting slider 41, the transmitter 61 and feedback device 62 assist the operator in aligning blowout preventer 33 and injection head 2. S3: The level of the injection head 2 is detected by the level instrument 63. If it is not level, the first frame 111 and the second frame 112 are adjusted, or only the first frame 111 is adjusted, or only the second frame 112 is adjusted. The position of the sliding guide block 52 on the guide rail 51 is adjusted until the level instrument 63 reports that the injection head 2 is level. At this time, all the adjustment procedures before the operation are completed, and the continuous tubing operation begins.

[0055] In one embodiment, the operation begins after the injection head 2 is level. During the operation, the level instrument 63 detects the level status of the injection head 2 in real time. If it is not level, it is adjusted through steps S1 to S3 to compensate for the positional deviation of the injection head 2 during the operation until the operation is completed.
