Description

Technical Field

[0001] This utility model relates to the field of oil wellhead technology, specifically to an oil wellhead process pipe assembly and an oil wellhead device. Background Technology

[0002] The wellhead equipment is the core equipment installed at the oil and gas wellhead to control fluid pressure and adjust production parameters. It mainly consists of three parts: casing head, tubing head, and Christmas tree.

[0003] The wellhead manifold (also known as the wellhead manifold or production manifold) is a core component of the oilfield surface system, used to control the fluids produced by the well (crude oil, natural gas, water, sand, etc.) and safely guide them to downstream processing facilities. Essentially, it is a high-pressure pipeline network system that, through the combination of valves, flanges, and tees, achieves functions such as flow control, pressure regulation, safety protection, and multi-well aggregation.

[0004] Conventional wellhead process piping sets have some limitations in design and use. For example, their fixed structure makes it difficult to adjust flexibly according to the actual wellhead conditions, resulting in poor adaptability when applied to wellheads of different sizes and complexities. Often, it is necessary to customize process piping sets for specific wellheads, which not only increases costs but also extends the delivery and use cycle of the equipment. Utility Model Content

[0005] The purpose of this utility model is to provide an oil wellhead process pipe assembly and an oil wellhead device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil wellhead process pipe assembly and an oil wellhead device, comprising a diversion end component and a combined pipe component. Combined pipe components are horizontally installed on both the left and right sides of the diversion end component, and a regulating valve component is connected to the end of the combined pipe component away from the diversion end component. Furthermore, a bend pipe component is connected to the end of the regulating valve component away from the combined pipe component. Sealing components are installed on the upper and lower sides and the front and rear sides of the diversion end component. The diversion end component includes a diversion component body, a stabilizing seat, and a combined seat. A stabilizing seat is installed on the side of the diversion component body, and a combined seat is disposed in the middle of the surface of the stabilizing seat away from the diversion component body.

[0007] Furthermore, the main body of the diverter adopts a regular hexahedral structure, and the stabilizing seats are respectively installed on the six side facades of the main body of the diverter, and the stabilizing seats and the combination seats are integrated into one structure.

[0008] Furthermore, the end of the combined pipe component away from the regulating valve component is flangedly connected to the combined seat, and the end of the regulating valve component away from the combined seat is flangedly connected to the regulating valve component.

[0009] Furthermore, the regulating valve component includes a main valve body, a handwheel, and a connecting end. The handwheel is installed on the top of the main valve body, and connecting ends are provided at both the left and right ends of the main valve body. Moreover, the connecting ends are connected to the main valve body through a rotary joint pipe structure.

[0010] Furthermore, the bent pipe component includes a bent pipe body, a rotating pipe, and a connecting end. Both ends of the bent pipe body are connected and installed with rotating pipes, and the connecting end is installed at the end of the rotating pipe away from the bent pipe body. The rotating pipe adopts a rotary joint pipe structure for use.

[0011] Furthermore, the end of the regulating valve component away from the combined pipe component is connected to the bend component by a flange structure, and the cover component is installed on the side surface of the diversion end component through the flange structure.

[0012] Furthermore, the outer surfaces of the diversion end component, the combined pipe component, the regulating valve component, the bend component, and the cover component are all coated with a protective coating, and the protective coating is made of polytetrafluoroethylene.

[0013] An oil wellhead device is provided, wherein the oil wellhead device is equipped with the oil wellhead flow pipe assembly as described above.

[0014] This utility model provides an oil wellhead process pipe assembly and an oil wellhead device, which have the following beneficial effects:

[0015] 1. This utility model, through the structural design of the diversion end component, specifically the stable seat structure with a combined base connected to the side of the diversion component body, provides higher stability and reliability when connected to the combined pipe component. This effectively avoids leakage problems caused by unstable connections, improving the working efficiency and safety of the entire oil wellhead process pipe assembly. Simultaneously, the hexagonal structure of the diversion component body ensures more uniform fluid distribution during diversion, reducing the impact force of the fluid on the pipe wall and further extending the service life of the equipment. Furthermore, the modular structure, through the combined use of the diversion end component, combined pipe component, regulating valve component, bend component, and cap component, allows for arbitrary combination, expansion, and splicing of the device structure, enabling the oil wellhead process pipe assembly to adapt to the needs of oil wellheads of different scales and complexities. This greatly enhances the versatility and flexibility of the equipment. Moreover, the flange connection between the components not only facilitates installation and disassembly, simplifying later maintenance and repair, but also ensures the sealing of the connection points, effectively preventing fluid leakage and guaranteeing the smooth operation of oil production.

[0016] 2. This utility model utilizes the design of the regulating valve component. The handwheel installed on the main valve body facilitates manual adjustment by the operator to adapt to different production parameter requirements. The connecting end is connected to the main valve body via a rotary joint pipe structure. This design not only makes the installation and disassembly of the regulating valve component more convenient but also improves its sealing performance, effectively preventing fluid leakage during adjustment. It also facilitates the operation and use of the regulating valve component. The design of the bend component utilizes a rotary joint pipe structure for the rotating pipes connected at both ends. This design provides greater flexibility during installation and use, allowing for angle adjustment according to actual needs, thus better adapting to different oil wellhead environments. Simultaneously, the docking end ensures a tighter and more reliable connection between the bend component and other components. Furthermore, the outer surfaces of the diversion end component, combined pipe component, regulating valve component, bend component, and sealing cap component are all coated with a protective coating made of polytetrafluoroethylene (PTFE). This design not only improves the equipment's corrosion resistance but also extends its service life. Attached Figure Description

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] like Figures 1 to 5 As shown, an oil wellhead process pipe assembly and oil wellhead device include a diversion end component 1 and a combined pipe component 2. Combined pipe components 2 are horizontally installed on both the left and right sides of the diversion end component 1. A regulating valve component 3 is connected to the end of the combined pipe component 2 furthest from the diversion end component 1, and a bend component 4 is connected to the end of the regulating valve component 3 furthest from the combined pipe component 2. Sealing components 5 are installed on the upper and lower sides and the front and rear sides of the diversion end component 1. The diversion end component 1 includes a diversion body 101, a stabilizing seat 102, and a combined seat 103. A stabilizing seat 102 is installed on the side of the diversion body 101. 02, and a combination seat 103 is provided in the middle of the side surface of the stabilizing seat 102 away from the main body 101 of the diverter. The main body 101 of the diverter adopts a regular hexahedral structure, and the stabilizing seats 102 are respectively installed on the six side surfaces of the main body 101 of the diverter. Moreover, the stabilizing seats 102 and the combination seats 103 are integrated into one structure. The structural design of the stabilizing seats 102 connected to the side of the main body 101 of the diverter and the combination seats 103 makes the diverter end component 1 have higher stability and reliability when connected with the combined pipe component 2, effectively avoiding leakage problems caused by unstable connection.

[0025] like Figures 1 to 5 As shown, the end of the combined pipe component 2 furthest from the regulating valve component 3 is flangedly connected to the combined seat 103, and the end of the regulating valve component 3 furthest from the combined seat 103 is flangedly connected to the regulating valve component 3. The regulating valve component 3 includes a main valve body 301, a handwheel 302, and a connecting end 303. The handwheel 302 is installed on the top of the main valve body 301, and connecting ends 303 are provided at both ends of the main valve body 301. The connecting ends 303 are connected to the main valve body 301 through a rotary joint pipe structure. The bent pipe component 4 includes a bent pipe body 401, a rotating pipe 402, and a mating end 403. Rotating pipes 402 are connected to both ends of the bent pipe body 401, and a mating end 403 is installed at the end of the rotating pipe 402 furthest from the bent pipe body 401. The system employs a rotary joint pipe structure. The end of the regulating valve component 3 furthest from the combined pipe component 2 is connected to the bend component 4 via a flange structure. The cover component 5 is installed on the side surface of the diversion end component 1 via a flange structure. The outer surfaces of the diversion end component 1, combined pipe component 2, regulating valve component 3, bend component 4, and cover component 5 are all coated with a protective coating 6, which is made of polytetrafluoroethylene. The handwheel 302 installed on the main valve body 301 facilitates manual adjustment by the operator to meet the needs of different production parameters. The connecting end 303 is connected to the main valve body 301 via a rotary joint pipe structure. This design not only makes the installation and disassembly of the regulating valve component 3 more convenient but also improves its sealing performance.

[0026] By combining the components 1 (diversion end), 2 (combined pipe), 3 (regulating valve), 4 (bend pipe), and 5 (sealing cap), and utilizing a modular structure, the device can be arbitrarily combined, expanded, and spliced. This allows the wellhead process pipe assembly to adapt to the needs of wellheads of different sizes and complexities, greatly enhancing the equipment's versatility and flexibility. The surface is coated with a protective coating 6, which is made of polytetrafluoroethylene (PTFE). This design not only improves the equipment's corrosion resistance but also extends its service life.

[0027] In summary, as Figures 1 to 5 As shown, when using the oil wellhead process pipe assembly and oil wellhead device, firstly, according to the usage requirements, the diversion end component 1, the combination pipe component 2, the regulating valve component 3, the bend component 4, and the cap component 5 are matched and used as needed. They are then combined with the stabilizing seat 102 and the combination seat 103 on the side of the diversion component body 101 through flange connection to form a complete oil wellhead process pipe assembly.

[0028] During installation, operators can flexibly adjust the position and angle of each component according to the actual layout and needs of the oil wellhead. For example, by using the rotation function of the rotating pipes 402 at both ends of the bent pipe component 4, the fluid flow direction can be easily changed to adapt to pipe connections in different directions.

[0029] After the assembled wellhead process pipe assembly is installed at the corresponding position at the wellhead, the operator can adjust the flow rate and pressure of the fluid by using the handwheel 302 on the regulating valve component 3. When it is necessary to increase the flow rate, turn the handwheel 302 clockwise to increase the opening of the passage in the main valve body 301; when it is necessary to decrease the flow rate or shut off the fluid, turn the handwheel 302 counterclockwise. This manual adjustment method is simple and direct, and allows the operator to make quick adjustments on-site according to the actual situation.

[0030] During daily use, the protective coating 6 of PTFE on the outer surface of each component effectively resists corrosive substances in crude oil, natural gas and other media, reducing equipment damage caused by corrosion, lowering maintenance costs and downtime. At the same time, the flange connection design allows for quick and convenient disassembly and installation when a component needs to be inspected or replaced, improving the maintainability of the equipment. By installing the above-mentioned wellhead process pipe assembly, the oil wellhead device can stably and efficiently control the fluid produced by the oil well and safely guide it to downstream processing facilities, providing a reliable guarantee for the smooth progress of oil extraction operations.

Many modifications and variations will be apparent to those skilled in the art.
