Description

Technical Field

[0001] This utility model relates to the field of oil extraction technology, and in particular to a multi-protected, fireproof, flame-retardant, and heat-insulating insulation sleeve for oil wellheads. Background Technology

[0002] The Christmas tree is a wellhead device used to extract oil in flowing wells and mechanically operated wells. It is the main equipment at the top of the oil and gas well for controlling and regulating oil and gas production. It mainly consists of three parts: casing head, tubing head, and Christmas tree body. When the outside temperature is low in winter, it will affect the use of the Christmas tree, so it is necessary to insulate it.

[0003] In existing technologies, the traditional method of wrapping rock wool or glass wool with sheet metal is commonly used for insulation of oil wellheads. This method has significant drawbacks: First, its insulation effect is limited, and heat loss remains substantial; second, the traditional sheet metal outer shell lacks effective fire resistance in the harsh, flammable, and explosive environment of oil fields, posing a safety hazard; third, the sheet metal structure is bulky, inconvenient to install and disassemble, and prone to corrosion, resulting in high maintenance costs. Furthermore, existing insulation structures typically have a single function, lacking integrated consideration of multiple protective functions such as reflective insulation and mechanical reinforcement, making it difficult to meet the higher requirements of modern oil fields for equipment safety, energy conservation, and long-term stable operation.

[0004] Therefore, it is necessary to provide a new multi-layered protective fireproof and flame-retardant insulation sleeve for oil well trees to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-protected, fireproof, flame-retardant, and heat-insulating oil well insulation sleeve.

[0006] This utility model provides a multi-protection fireproof and flame-retardant heat-insulating oil production tree insulation sleeve, including an oil production tree body, a protective cover wrapped around the outside of the oil production tree body, a connecting component on the protective cover, and the protective cover having a heat insulation and reflective layer, a heat insulation layer, a reinforcing layer and a fireproof finishing layer arranged sequentially from the inside to the outside.

[0007] Preferably, the connecting component includes a first connecting strap, a D-ring buckle, and a second connecting strap. The protective cover is sewn with the first connecting strap, and a D-ring buckle is fixedly connected to one end of the first connecting strap. The second connecting strap is sewn to the side of the protective cover away from the first connecting strap, and the second connecting strap and the D-ring buckle are interlocked.

[0008] Preferably, the heat-insulating reflective layer is made of fiberglass cloth or fiberglass cloth or ceramic fiber cloth coated with aluminum foil.

[0009] Preferably, the insulation layer is made of ceramic fiber cotton, glass fiber cotton or rock wool felt.

[0010] Preferably, the reinforcing layer is made of fiberglass cloth or wire mesh.

[0011] Preferably, the fireproof finishing layer is made of silicone-coated fiberglass cloth, PVC-coated fiberglass cloth, or high-silica cloth.

[0012] Compared with related technologies, the multi-protection fireproof and flame-retardant insulation sleeve for oil wellheads provided by this utility model has the following beneficial effects:

[0013] This utility model provides a multi-layered, fire-retardant, and heat-insulating insulation sleeve for wellheads. Its multi-layered composite structure integrates heat insulation and reflection, long-term insulation, structural reinforcement, and fire-resistant finishing. It provides progressively effective protection against heat radiation, heat conduction, mechanical impact, and open flame environments, fundamentally improving the overall performance and reliability of the wellhead insulation sleeve. The combination of the fire-resistant finishing layer and the insulation layer not only ensures the product's high flame retardancy and enhances well site safety, but also significantly reduces heat loss through the synergistic effect of the heat-reflective layer and the insulation layer, resulting in high insulation efficiency and significant energy savings. The reinforcement layer greatly enhances the overall mechanical strength and damage resistance of the insulation sleeve. The included connecting components allow for quick installation and disassembly, facilitating routine inspection and maintenance of the wellhead, greatly improving practicality and work efficiency.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figures 1-4 ,in, Figure 1 A schematic diagram of the three-dimensional structure of the multi-protected, fireproof, flame-retardant, and heat-insulating insulation sleeve for oil wells provided by this utility model; Figure 2 This is a three-dimensional structural diagram of the oil well tree body provided by this utility model; Figure 3 A three-dimensional structural diagram of the connecting component provided by this utility model; Figure 4 A schematic diagram of the protective cover structure provided by this utility model.

[0021] Example 1

[0022] In the specific implementation process, such as Figures 1-4 As shown, a multi-protection fireproof and flame-retardant heat-insulating oil production tree insulation sleeve is used to wrap the oil production tree body 1, providing it with comprehensive heat insulation, fireproofing and physical protection.

[0023] The insulation sleeve includes a protective cover 2 and a connecting assembly 3. The protective cover 2 is custom-cut according to the shape and size of the oil well trunk 1, and can tightly wrap around the outside of the oil well trunk 1. The protective cover 2 adopts a multi-layer composite structure, with a heat-insulating and reflective layer 4, a heat-insulating layer 5, a reinforcing layer 6, and a fire-resistant finishing layer 7 stacked sequentially from the inside out. The layers are fixed together by high-temperature resistant stitching or by high-temperature resistant adhesive to ensure the stability and durability of the overall structure.

[0024] The connecting assembly 3 is used to securely fix the protective cover 2 to the tree trunk body 1. In this embodiment, the connecting assembly 3 includes a first connecting strap 8, a D-ring buckle 9, and a second connecting strap 10. The first connecting strap 8 is sewn and fixed to one side edge of the protective cover 2, and a D-ring buckle 9 is fixedly connected to the free end of the first connecting strap 8. The second connecting strap 10 is sewn and fixed to the other side edge of the protective cover 2 opposite to the first connecting strap 8. During installation, after the protective cover 2 is wrapped around the tree trunk body 1, the free end of the second connecting strap 10 is passed through the D-ring buckle 9 and pulled tight in the opposite direction, thus achieving quick and reliable fixing and tension adjustment.

[0025] In this embodiment, the heat-insulating reflective layer 4 is made of fiberglass cloth coated with aluminum foil. This layer utilizes the high reflectivity of aluminum foil to reflect a large amount of radiant heat emitted by the oil well body 1 back, thereby effectively reducing heat loss and blocking the entry of external heat.

[0026] Insulation layer 5 is made of ceramic fiber cotton. Ceramic fiber cotton has an extremely low thermal conductivity and excellent high-temperature resistance, making it the main body of thermal insulation and minimizing heat loss through conduction.

[0027] The reinforcing layer 6 is made of steel wire mesh. This reinforcing layer 6 is embedded in the composite structure, which significantly improves the overall mechanical strength and impact resistance of the insulation jacket and can effectively prevent damage caused by collisions with external objects.

[0028] The fire-resistant finishing layer 7 is made of silicone-coated fiberglass cloth. As the outermost layer, this layer is directly exposed to the external environment and has excellent fire-retardant, waterproof, oil-proof, corrosion-resistant, and wear-resistant properties, providing final protection for the internal structure and extending the service life of the insulation sleeve.

[0029] Example 2

[0030] This embodiment has the same basic structure as Embodiment 1. The main difference lies in the material selection of the protective cover 2, in order to suit different working conditions and cost considerations.

[0031] In this embodiment, the materials selected for each functional layer are as follows:

[0032] The heat-insulating reflective layer 4 is made of ceramic fiber cloth. Ceramic fiber cloth itself has good high-temperature resistance and heat insulation properties, and also has a certain reflective effect.

[0033] Insulation layer 5 is made of fiberglass wool. Fiberglass wool is a commonly used insulation material that is cost-effective and has good insulation performance.

[0034] Reinforcing layer 6 is made of fiberglass cloth. Fiberglass cloth has good strength and corrosion resistance, provides sufficient structural reinforcement, and is relatively soft in texture.

[0035] The fire-resistant finishing layer 7 is made of PVC-coated fiberglass cloth. PVC-coated fiberglass cloth also has good fire-resistant, waterproof, and abrasion-resistant properties, making it an economical and practical choice.

[0036] Example 3

[0037] The structure of this embodiment is the same as that of Embodiment 1, the difference being the choice of material for the protective cover 2.

[0038] In this embodiment, the materials selected for each functional layer are as follows:

[0039] The heat insulation and reflective layer 4 is made of pure fiberglass cloth, which mainly serves as basic insulation and high temperature resistance.

[0040] Insulation layer 5 is made of rock wool felt. Rock wool felt has excellent fire resistance and is relatively inexpensive.

[0041] The 6th reinforcing layer is made of steel wire mesh, providing the strongest mechanical protection.

[0042] The fire-resistant finishing layer 7 is made of high-silica fabric. High-silica fabric has high temperature resistance and fire resistance properties close to those of inorganic materials, making it suitable for special environments with extremely high fire protection requirements.

[0043] This invention achieves multiple layers of protection through a multi-layered composite structure. After installation, the fire-resistant finishing layer 7 resists external open flames, oil stains, and severe weather; the reinforcing layer 6 resists mechanical impact; the insulation layer 5 effectively blocks heat transfer, achieving efficient insulation; and the heat-reflective insulation layer 4 further enhances insulation efficiency by reflecting radiant heat. The connecting components 3 ensure convenient installation and reliable connection.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
