Description

Technical Field

[0001] This utility model relates to the field of oil and gas extraction, and in particular to an operating platform for oil and gas extraction. Background Technology

[0002] Volumetric fracturing, a key technology for increasing the production of tight oil and gas and shale oil and gas, relies heavily on its coordination with horizontal well fracturing technology for successful implementation. To this end, the industry has developed cable-pumped bridge plugs and perforation techniques. While these technologies have significantly enhanced operational efficiency at the wellhead, they have also introduced additional challenges. Specifically, the addition of pumping equipment such as blowout preventers (BOPs), BOP tubing, and BOP boxes significantly increases the overall height of the wellhead equipment, requiring operators to rely on a dedicated operating platform for installation and necessary maintenance. Furthermore, the high flow rate and high pressure environment generated during volumetric fracturing operations can easily cause vibrations in the wellhead equipment, leading to loosening of connections. This necessitates frequent visits to the operating platform for inspection, alignment, and maintenance.

[0003] However, the design of currently widely used operating platforms is relatively rudimentary. Due to the differences in the height of different wellheads, existing operating platforms can often only be configured for a single wellhead height. Once used at a certain wellhead, it is difficult to move them to another wellhead with a different height for continued use. Therefore, existing operating platforms lack sufficient flexibility and adaptability. Utility Model Content

[0004] The purpose of this invention is to overcome the problem that existing wellhead operating platforms cannot adapt to wellheads of different heights, and to provide an operating platform for oil and gas extraction.

[0005] This utility model provides an operating platform for oil and gas extraction, comprising:

[0006] A vertical component, the bottom of which is used for support on the ground.

[0007] The first platform is capable of moving up and down along the vertical component and is located at the wellhead pipe position.

[0008] The second platform is movable up and down along the vertical component and is located above the first platform.

[0009] This invention provides an operating platform for oil and gas extraction. The vertical component supports a first platform and a second platform on the ground. Both the first and second platforms provide operating platforms for construction personnel. The first platform is used to operate equipment located on the wellhead pipeline, such as valves, pressure monitoring devices, and blowout preventers. The second platform is used to operate equipment located above the wellhead pipeline, which includes a blowout preventer pipe and blowout preventer box. Both the first and second platforms can move up and down along the vertical component, allowing the operating platform to be adjusted according to the height of the wellhead pipeline. This solves the problem of traditional wellhead operating platforms being unable to adapt to wellheads of different heights, improving the flexibility and adaptability of the wellhead operating platform.

[0010] The first platform and the second platform can move up and down along the vertical component in the following ways: the vertical component is provided with a toothed rail, and both the first platform and the second platform are provided with gears and a drive device. The drive device drives the gears to rotate, so that the gears roll along the toothed rail, thereby driving the first platform or the second platform to move up and down; or the vertical component is provided with a plurality of holes evenly distributed along the height direction, and the first platform and the second platform can be connected to the holes at different height positions.

[0011] The planar shapes of the first and second platforms can be rectangular, U-shaped, or circular. The vertical components can be located precisely in the middle of the two platforms; alternatively, multiple vertical components can exist, distributed around the periphery of the two platforms. The wellhead pipe can be located near the outer edge of the first platform or can pass through the central area of ​​the first platform.

[0012] Preferably, a lifting mechanism is connected to the bottom of the vertical component, which is used to move the vertical component up and down. This solution introduces the lifting mechanism when the first platform and the second platform have been installed in their predetermined positions on the vertical component, and adjusting their height becomes inconvenient. The lifting mechanism can precisely adjust the height of the entire operating platform within a small range, enabling further fine-tuning of the platform's height. This solution further enhances the flexibility and adaptability of the operating platform, allowing it to better meet different operational needs.

[0013] The lifting mechanism can be a hydraulic telescopic rod, which moves the vertical component up and down by extending and shortening the hydraulic telescopic rod.

[0014] Preferably, the system further includes several clamps for connecting to the outer wall of the wellhead pipe. Each clamp is matched with a support rod and a ground fixing component, with both ends of the support rod connected to the clamp and the ground fixing component, respectively. The clamps form a ring structure and are connected to each other using bolts or snap-fit ​​devices to fix the wellhead pipe in the middle. The size of the ring structure can be flexibly adjusted by changing the distance between adjacent clamps. Different wellhead pipes may differ not only in height but also in outer diameter. The purpose of this solution is to fix the wellhead pipe while accommodating wellhead pipes of various diameters, thereby enhancing the compatibility and adaptability of the solution to wellhead pipes of different sizes.

[0015] Preferably, the ground fixing component includes a main board and a fixing plate. The main board is fixed to the ground with bolts, and the fixing plate is vertically welded to the main board. The support rod is connected to the fixing plate via a pin. In this design, the support rod can rotate around the pin, allowing adjustment of the angle between the support rod and the ground as needed. The pin connection method enables easy disassembly of the support rod when no external force is applied, greatly facilitating the installation and disassembly process.

[0016] Preferably, the vertical component is a pole, which is connected to the outer edge of the first platform and the outer edge of the second platform. The number of poles is at least three, and they are evenly distributed and connected to the outer edges of the first and second platforms. This design optimizes the volume and weight of the vertical component, thereby facilitating the flexible transfer and deployment of the operating platform between wellhead pipelines in various engineering projects.

[0017] Preferably, the upright has a plurality of holes evenly distributed along its height, and both the first platform and the second platform are provided with insert rods that match the holes. By inserting the insert rods into the holes, the first platform is connected to the upright, and the second platform is also connected to the upright. This solution allows for easy fixing of the first platform and the second platform at different height positions on the upright, and provides flexibility. It also allows the first platform and the second platform to be disassembled and reinstalled at other height positions on the upright when needed.

[0018] Preferably, the first platform is equipped with a first ladder, and the second platform is equipped with a second ladder. The first ladder connects the ground and the first platform, facilitating easy access for construction workers to the first platform. The second ladder connects the ground and the second platform, facilitating easy access for construction workers to the second platform. The first ladder is hinged to the first platform, allowing it to adjust accordingly to changes in the height of the first platform. Similarly, the second ladder is hinged to the second platform, allowing it to adjust accordingly to changes in the height of the second platform.

[0019] Preferably, the first platform is equipped with a first guardrail, and the second platform is equipped with a second guardrail. The first guardrail and the second guardrail are used to form a protective fence structure around the first platform and the second platform, respectively, to ensure the safety of construction personnel.

[0020] Preferably, both the first platform and the second platform have a U-shaped structure, with the central opening area of ​​the U-shaped structure matching the size of the wellhead pipe. This design allows the wellhead pipe to pass smoothly through the center of the first platform, while the blowout preventer above the wellhead pipe can also pass through the center of the second platform. This design provides construction personnel with the convenience of operating the corresponding equipment from different directions, greatly enhancing the practicality and convenience of the operating platform.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides an operating platform for oil and gas extraction. Both the first platform and the second platform can move up and down along the vertical component, allowing the operating platform to be adjusted according to the height of the wellhead pipeline. This solves the problem that traditional wellhead operating platforms cannot adapt to wellheads of different heights, and improves the flexibility and adaptability of the wellhead operating platform.
