[0002] In the process of oil extraction, oil wells and water injection wells are usually used simultaneously to optimize production efficiency and oil recovery rate. The injection effect of the water injection well can maintain the pressure of the reservoir and push the oil or natural gas toward the oil well, so that the oil well can continuously produce oil or natural gas. In a cold environment, the surface equipment of the oil wells and water injection wells may be affected by the low temperature, causing the equipment to freeze. The freezing may cause damage to the equipment and hinder the normal operation of the oil wells and water injection wells. Therefore, for oil wells and water injection wells in cold areas, insulation is necessary to prevent the equipment from freezing.

[0003] Traditional oil well (including water injection well) insulation material is glass cloth wrapped with insulation cotton, but glass fiber cloth and paint are harmful to the human body and are not convenient for protecting the health of workers. The old insulation materials that are removed need special disposal, which will lead to increased costs. At the same time, the insulation layer is not tight. After rainwater enters the insulation layer through the gap, it is absorbed by the felt inside and is not easy to dry, causing the wrapped pipelines and valves to be in a humid environment for a long time, which is easy to be corroded, which is not conducive to the protection of oil wells and water injection wells.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 2-4 The utility model provides an embodiment: an antifreeze wellhead insulation device, comprising a wear-resistant cloth 1, a waterproof cloth 13 is fixedly connected to one side of the outer wall of the wear-resistant cloth 1, a fireproof cloth 14 is fixedly connected to one side of the outer wall of the waterproof cloth 13, a heat-insulating cloth 15 is fixedly connected to one side of the outer wall of the fireproof cloth 14, a plurality of straps 2 are fixedly connected to the outer wall of the wear-resistant cloth 1, a bayonet 8 is rotatably connected to one side of the outer wall of the strap 2, a plurality of jacks 11 are provided inside the bayonet 8, a Velcro 1 9 is fixedly connected to one side of the outer wall of the strap 2, and a Velcro 2 10 is fixedly connected to the other side of the outer wall of the bayonet 8;

[0025] Specifically, first, wrap the wear-resistant cloth 1 along its cut edge so that it can fit tightly to the surface of the wellhead and the branch. After the wear-resistant cloth 1 wraps the wellhead, it needs to be fixed with the strap 2. The strap 2 is passed through the bayonet 8. Then, after the strap 2 is tightened, the bayonet 8 is inserted into the socket 11 for fixation. This step is to ensure that the wear-resistant cloth 1 remains stable during use. Finally, the wear-resistant cloth 1 is further fixed using Velcro 10. Velcro 2 10 can be tightly adhered to Velcro 1 9 to ensure that the wear-resistant cloth 1 fits tightly against the wellhead and branch surface. The wear-resistant cloth 1 is arranged on the outermost side and is designed with rubber material to protect the wrapping mechanism. A waterproof cloth 13 is arranged on the inside of the wear-resistant cloth 1, which is made of fire-resistant polyester cloth so that it can be used in high temperature environments. A fire-resistant cloth 14 is arranged on the inside of the waterproof cloth 13, which is made of polyvinyl chloride coated cloth to prevent water infiltration. An insulating cloth 15 is arranged inside the waterproof cloth 13, and the material is tin film composite cloth to protect the wellhead.

[0026] Reference Figure 1 and Figure 3A charging component is provided on one side of the wear-resistant cloth 1, and the charging component includes a fixing rod 5 and a solar panel 4. The bottom of the solar panel 4 is fixedly connected to the top of the fixing rod 5. The fixing rod 5 is provided on one side of the wear-resistant cloth 1. A storage box 6 is fixedly connected to one side of the outer wall of the fixing rod 5. The storage box 6 is electrically connected to an electric heating belt 3. A plurality of soft hooks 12 are fixedly connected to the inside of the wear-resistant cloth 1, and the outer wall of the electric heating belt 3 is provided inside the soft hook 12;

[0027] Specifically, during the insulation process, the solar panel 4 can convert solar energy into electrical energy, and then store the electrical energy in the storage box 6. The storage box 6 acts as an energy regulator, which can control the heating of the electric heating tape 3 according to actual conditions. In this way, it can ensure that the temperature at the wellhead is maintained within a constant range. In order to achieve this goal, the electric heating tape 3 needs to be fixed inside the wear-resistant cloth 1. The electric heating tape 3 can be fixed to any part of the wear-resistant cloth 1 through the soft hook 12 to make the heating process more efficient.

[0028] Reference Figure 1 and Figure 5 The bottom of the fixed rod 5 is fixedly connected to a support rod 16, the outer wall of the fixed rod 5 is rotatably connected to a bracket 7 of an annular array, the bottom of the support rod 16 is fixedly connected to a threaded column 17, one side of the outer wall of the bracket 7 is rotatably connected to a transmission rod 19, the outer wall of the threaded column 17 is threadedly connected to a driving ring 18, one side of the transmission rod 19 is rotatably connected to a slider 21, the slider 21 is slidably connected to the inside of the driving ring 18, and the bottom of the threaded column 17 is fixedly connected to a base 20;

[0029] Specifically, first, the driving ring 18 can rotate around the threaded column 17 to realize the rising of the slider 21. The slider 21 is connected to the bracket 7 through the transmission rod 19, and the bracket 7 can be propped up by the transmission rod 19 to create conditions for the placement of the solar panel 4.

[0030] Working principle: when the wear-resistant cloth 1 is installed, the wear-resistant cloth 1 can be wrapped along its cut edge, so that the wear-resistant cloth 1 can be attached to the surface of the wellhead and the branch. After the wear-resistant cloth 1 wraps the inlet, the wear-resistant cloth 1 can be wrapped with the strap 2 and then passed through the bayonet 8. After the strap 2 is tightened, the bayonet 8 is inserted into the inside of the jack 11 for fixation, and then the Velcro 2 10 is attached to the Velcro 1 9 for further fixation. When keeping warm, the solar panel 4 can store electrical energy in the battery box 6, and the battery box 6 controls the heating of the electric heating tape 3, and the electric heating tape 3 can be fixed inside the wear-resistant cloth 1 by the soft hook 12, so as to facilitate the control of the constant temperature of the wellhead. When the solar panel 4 is erected, the drive ring 18 can be rotated on the threaded column 17 to make the slider 21 rise, and the bracket 7 can be propped up by the transmission rod 19 to place the solar panel 4.
