[0021] Example: Please refer to Figure 1-3 This utility model provides a technical solution: a split skid-mounted device for oil manifolds, including a manifold skid support 7 and a manifold skid frame 13. The manifold skid support 7 and the manifold skid frame 13 adopt a split frame design, which can achieve effective on-site layout and is not affected by the site. The manifold skid support 7 is the centralized working area of ​​the manifold, and the manifold skid frame 13 is the installation area of ​​electrical control and the access point of other equipment. A valve insulation box 21 is installed on the top of the manifold skid frame 13. The valve in the valve insulation box 21 is connected to the instrument through a three-way pipe assembly A17. The instrument and meter pipeline 19 is connected to the horizontal pipe A22. The horizontal pipe A22 is connected to the horizontal pipe B29 and the horizontal pipe C3 installed on the manifold skid bracket 7 through the tee assembly B24. One end of the horizontal pipe C3 is connected to the riser 31 through the clamp valve assembly 26. The top of the riser 31 is connected to the casing horizontal pipe 2. One end of the casing horizontal pipe 2 is connected to the oil pipe tee assembly 14. The oil pipe tee assembly 14 is connected to the wellhead (oil outlet). One end of the horizontal pipe B29 is connected to the casing tee assembly 18.

[0022] A temperature transmitter 35 is installed on the instrumentation pipeline 19. The horizontal pipe A22 and the tee assembly B24 are connected to the instrumentation pipeline 19 by clamp assembly 4. The tee assembly A17 is connected to the instrumentation pipeline 19 by clamp assembly 4.

[0023] The tee assembly B24 is connected to the clamp check valve assembly 28 via the clamp assembly 4. The clamp check valve assembly 28 is connected to the horizontal pipe C3 via the clamp assembly 4. The horizontal pipe C3 is connected to the riser 31 via the clamp valve assembly 26. The riser 31 is connected to the 90-degree clamp elbow 25 via the clamp assembly 4. The 90-degree clamp elbow 25 is connected to the sleeved horizontal pipe 2 via the clamp assembly 4. The sleeved horizontal pipe 2 is connected to the oil pipe tee assembly 14 via the clamp assembly 4. The clamp assembly 4 is used to achieve quick connection of each pipeline.

[0024] A sampling valve 36 is installed on the riser 31 to facilitate oil and gas sampling.

[0025] One end of the horizontal pipe B29 is connected to the tee assembly B24 via the clamp valve assembly 26, and the other end of the horizontal pipe B29 is connected to the sleeve tee assembly 18 via the 90-degree clamp elbow 25. The 90-degree clamp elbow 25 facilitates the adjustment of the manifold in a 90-degree direction.

[0026] Both the sleeved horizontal pipe 2 and the sleeved tee assembly 18 are installed on the manifold fixing bracket 8, which is fixed on the manifold skid bracket 7 to provide support and stability.

[0027] Horizontal pipe C3, horizontal pipe B29, and tee assembly B24 are all fixed to the manifold skid bracket 7 by U-shaped clips 11. Instrument pipe 19 and tee assembly A17 are all fixed to the manifold skid frame 13 by U-shaped clips 11 to ensure stable installation.

[0028] The clamp assembly 4 consists of an upper clamp cover and a lower clamp cover. A steel ring 1 is provided between the upper clamp cover and the lower clamp cover. The upper clamp cover and the lower clamp cover are fixedly connected by clamp fastening studs 5. The clamp assembly 4 achieves a quick connection function.

[0029] Working Principle: A split skid-mounted manifold assembly first performs on-site surveying and design for different oil wells, measuring the height of the production riser and the length of the crossbar to achieve standardized manufacturing. The standardized manifold skid-mounted assembly replaces the on-site welding of split parts, tees, and cut pipe fittings, as well as flange connections, with clamp connections. No welding or hot work is required on-site, reducing safety hazards. Installation is standardized; on-site installation only requires connecting the clamp tee to the nozzle end of the production tree to complete the manifold installation. Accessories such as tees, elbows, risers, crossbars, clamp heads, clamp covers, valves, etc., are manufactured according to the drawings. Manufacturing and installation are carried out according to the assembly drawings, requiring only on-site interface connection. Using a standardized split skid-mounted manifold assembly significantly reduces on-site construction workload, effectively shortens the construction cycle, and reduces labor costs.

[0030] Advantages of using this method:

[0031] 1. Improved installation efficiency: Standardized manufacturing of skid-mounted devices improves manufacturing efficiency. What used to take 5 people 3 days can now be completed by 1 person in 0.5 days with the split skid-mounted device.

[0032] 2. Flexible layout: Due to its modular design, the construction site can be effectively arranged according to the actual space on site.

[0033] 3. Production capacity: Since the split skid-mounted device is manufactured in a standardized and modular manner, the production capacity will be increased accordingly. At the same time, many components are made from standard and universal parts, and mass production effectively reduces raw material costs.

[0034] 4. Environmental protection: Since 95% of the manufacturing work of the overall skid-mounted device is prefabricated in the factory, in the past, this 95% of the manufacturing work would have been completed on the construction site. By reducing the on-site construction links, such as steel cutting and welding, the environmental pollution at the construction site is effectively reduced.

[0035] 5. Reuse: Replaced parts (such as clamps) can be reused after being inspected and found to be correct.

[0036] The above embodiments merely illustrate the implementation of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
