Description

Technical Field

[0001] This utility model relates to the field of oil and gas extraction technology, and in particular to a protective mechanism for wellhead devices. Background Technology

[0002] During the relocation of drilling equipment at a simultaneous drilling and production well site, wellhead equipment operating normally in close proximity to the wellhead typically requires protective measures to prevent damage to precision components and potential safety hazards from collisions with hoisting equipment. Currently, a common practice is to weld a protective cover using steel pipes and iron plates above the wellhead equipment. However, because the width and height of the wellhead equipment vary from well to well, protective covers cannot be interchanged. Custom-made covers are necessary for each wellhead, resulting in significant waste of manpower and resources. Furthermore, these covers are heavy, difficult to install and disassemble, and offer limited protection. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of existing wellhead devices, which use customized protective covers that easily lead to a large waste of manpower and material resources and have limited protective effects, and to provide a protective mechanism for wellhead devices.

[0010] Preferably, the main frame includes a first segment and a second segment arranged sequentially from bottom to top. The vertical projection of the first segment can at least cover the square wellbore pool at the wellhead, and the vertical projection of the second segment can at least cover the wellhead device within the square wellbore pool. This achieves a protective effect while reducing the overall manufacturing cost of the main frame.

[0011] Preferably, the width adjustment mechanism includes a slidingly fitted first joint and a second joint, wherein the first joint and the second joint comprise steel pipe components.

[0012] Preferably, the height adjustment mechanism includes a third joint and a fourth joint that slide together, the third joint and the fourth joint include steel pipe components, and a limiting component is provided between the third joint and the fourth joint.

[0013] Preferably, both the main frame and the fence components comprise a steel pipe composite frame structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1.

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0023] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer" used in the description of specific embodiments of this utility model to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0025] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0026] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0027] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0028] Example 1 like Figures 1-6 As shown, a protective mechanism for a wellhead device includes a main frame 1, a fence component, a baffle 12, a width adjustment mechanism 2, and a height adjustment mechanism 3.

[0029] The main frame 1 can be a steel pipe composite frame structure, including a top frame and legs 11 for supporting the top frame. The top frame can be a square frame structure formed by welding steel pipes. The legs 11 can be vertical steel pipes set below the top frame. The baffle 12 is connected to the top of the main frame 1, so that the top frame, legs 11 and baffle 12 can be combined to cover the wellhead device 20 (e.g., a gas production tree).

[0030] In optional implementations, such as Figure 1 As shown, a lifting lug 5 can be installed on the top of the main frame 1. This facilitates the overall hoisting, installation, and dismantling of the protective mechanism using lifting machinery. The lifting lug 5 can be configured to pass through the baffle 12, or it can be staggered with the baffle 12, depending on the actual situation, so as to facilitate the joint installation of the lifting lug 5 and the baffle 12 at the bottom of the main frame 1.

[0031] In optional implementations, such as Figure 1 As shown, the bottom of the main frame 1 can be detachably connected to rollers 6. This facilitates the installation, removal, and movement of the protective mechanism via the rollers 6. The rollers 6 can have a braking and fixing function, ensuring stable positioning of the main frame 1 after it has been moved into place. The rollers 6 can be removed as needed to prevent accidental movement of the protective mechanism during use.

[0032] In optional implementations, such as Figure 1 , Figure 3 As shown, a protective net 8 can be installed around the main frame 1, and the protective net 8 is detachably connected to the main frame 1. The protective net 8 can further provide a shielding and protective effect, preventing workers or tools from falling below the wellhead device 20.

[0033] In an optional implementation, the shielding net 8 can be a finished fine mesh grid fence. The height of the shielding net 8 can be set according to the height of the personnel, without completely covering the entire main frame 1. The shielding net 8 can effectively prevent personnel from entering the protected area of ​​the protective mechanism, and helps to reduce the risk of inspection personnel or tools falling into the wellhead square well pool 10 inside the protective mechanism, thereby improving the protective effect of the protective mechanism.

[0034] In optional implementations, such as Figure 2 As shown, a protective door 9 is hinged to the main frame 1 to facilitate the entry and exit of operators to carry out the operation of the wellhead device 20.

[0035] The fence components can be composed of multiple steel pipe welded into a mesh-like fence panel 4. The fence panel 4 can be rectangular. Multiple fence panels 4 can be connected by clamps, bolts, screws and other connectors to supplement the shielding of the space between the legs 11 and improve the overall shielding and protection effect of the main frame 1.

[0036] In an optional embodiment, the fence components can be made of 73mm×5.51mm steel pipes, with a longitudinal spacing of 1.5m, a transverse spacing of 0.5m, and diagonal bracing in the middle to form a rectangular mesh fence panel 4 with a single panel width not exceeding 2.4m. The corresponding main frame 1 can be made of 89mm×6.45mm steel pipes welded together to form a cubic frame structure. Each fence panel 4 can be prefabricated according to the actual situation and then combined and connected with the main frame 1 when in use. The baffle 12 can be made of 10mm thick steel plate. The overall height of the main frame 1 can be determined according to the height of the gas wellhead device 20.

[0037] In optional implementations, such as Figure 4 As shown, the vertical members of the fence component can be set to be at the same height as the legs 11 of the main frame 1 according to the actual situation, so that the fence component can be supported on the ground and together with the legs 11 maintain the overall structural stability of the protective mechanism.

[0038] The main frame 1 is equipped with a width adjustment mechanism 2 and a height adjustment mechanism 3. The width adjustment mechanism 2 is used to change the width of the main frame 1, and the height adjustment mechanism 3 is used to change the height of the main frame 1.

[0039] In optional implementations, such as Figure 5 As shown, the main frame 1 may include two frame components, left and right, each with independent support legs 11. The width adjustment mechanism 2 includes a slidingly fitted first joint 21 and a second joint 22. The first joint 21 and the second joint 22 may be steel pipe components with different diameters. The first joint 21 and the second joint 22 may be arranged relative to each other between the left and right frame components of the main frame 1. Through the coaxial sliding fit of the first joint 21 and the second joint 22, a telescopic structure is formed to realize the adjustment of the width dimension of the main frame 1. The structure is simple and easy to use.

[0040] In an optional implementation, after the width of the main frame 1 is changed by the width adjustment mechanism 2, the distance between adjacent legs 11 increases. The overall protective effect of the protective mechanism can be ensured by adding fence components or adding a shielding net 8.

[0041] In optional implementations, such as Figure 5As shown, the outrigger 11 may include upper and lower steel pipe components. The height adjustment mechanism 3 includes a slidingly fitted third joint 31 and a fourth joint 32. The third joint 31 and the fourth joint 32 may be steel pipe components with different diameters. The third joint 31 and the fourth joint 32 may be relatively arranged between the upper and lower parts of the outrigger 11. Through the coaxial sliding fit of the third joint 31 and the fourth joint 32, a telescopic structure is formed to realize the height adjustment of the outrigger 11, thereby realizing the height adjustment of the main frame 1. Several through holes may be provided on the third joint 31 and the fourth joint 32. Through the limiting component 33 passing through the through holes, the height of the outrigger 11 is limited, thereby stabilizing the height of the main frame 1. This ensures that the overall height of the protective mechanism can be maintained at least 0.2m higher than the wellhead device 20, so as to ensure the normal operation and use of the wellhead device 20.

[0042] In an optional embodiment, the limiting member 33 may be a bolt, a pin, or other steel rod.

[0043] In one or more implementations, such as Figure 3 , Figure 6 As shown, the main frame 1 is detachably connected to the counterweight 7, which is connected to the support leg 11 and / or fence components. This improves the stability of the protective mechanism and prevents displacement.

[0044] In an optional embodiment, the counterweight 7 can be a steel plate, steel block, or reinforced concrete block, and has a certain weight. The counterweight 7 can be connected to the support leg 11 or fence component by hooks, chains, etc., or it can be abutted against the side wall of the main frame 1 to prevent the main frame 1 from shifting and improve the overall stability of the protective mechanism.

[0045] In optional implementations, such as Figure 3 , Figure 6 As shown, a sleeve that fits the support leg 11 can be provided on the top of the counterweight 7. After removing the roller 6, the support leg 11 can be confined within the sleeve, so that the position of the support leg 11 relative to the counterweight 7 is stable and not easily moved.

[0046] In one or more implementations, such as Figure 4 , Figure 5 As shown, the main frame 1 may include a first segment 13 and a second segment 14 arranged sequentially from bottom to top. The vertical projection of the first segment 13 can at least cover the square well pool 10 at the wellhead, and the vertical projection of the second segment 14 can at least cover the wellhead device 20 within the square well pool. This can reduce the overall manufacturing cost of the main frame 1 while achieving a protective effect.

[0047] In optional implementations, such as Figure 5 , Figure 6As shown, the first segment 13 and the second segment 14 can be two cubic frame structures with differences on the vertical projection plane. Both are equipped with baffles 12 on the top and fences 4 on the side walls to form two main frames 1 with different cross-sectional areas. This allows the protective mechanism to be installed on the square well pool 10 at the wellhead and to concentrate the wellhead device 20 in the square well pool to play an effective protective role, reducing the repeated manufacturing cost of the wellhead protective mechanism and lowering the overall manufacturing cost of the protective mechanism.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
