Description
Technical Field
[0001] The utility model relates to the technical field of tool-type wellheads, in particular to a novel tool-type wellhead protection structure. Background Art
[0002] A tooled wellhead refers to a wellhead design used in oil field or natural gas exploration. It usually includes a wellhead equipment for connecting the drill bit and extracting underground resources. These equipment usually include pipes, valves, connecting equipment and other tools to control the production and operation of the wellhead for drilling and production operations. This type of wellhead usually requires frequent maintenance and monitoring to ensure its normal operation and safety.
[0003] The above-mentioned and existing related technologies often have the following defects: the tool wellhead needs to be connected to the oil field pipeline for use, and the flow rate of the oil in the oil field pipeline is controlled by using a valve to facilitate production and operation, thereby ensuring the normal and stable operation of the oil field pipeline. Since the oil field pipeline and the tool wellhead are connected by fixing bolts, they are affected by the environment. In rainy weather, rainwater can easily corrode the fixing bolts connecting the tool wellhead and the pipeline, causing the threaded surface of the fixing bolts to rust. The rust of the fixing bolts will reduce the fixing effect, resulting in a loose connection between the tool wellhead and the oil field pipeline.
[0004] To this end, we propose a new tool-type wellhead protection structure. Utility Model Content

[0034] like Figure 6As shown, the sealing device 5 includes a circular groove 57, which is provided on the surface of the tool well pipe 1. A sealing ring 51 is detachably installed on the inner wall of the circular groove 57. A screw 52 is threadedly connected to the inner wall of the tool well pipe 1. One end of the screw 52 is rotatably connected to a limit plate 54. A cone thorn 56 is fixedly connected to the surface of the limit plate 54. When the tool well pipe 1 is installed on the pipeline 4, the damaged sealing ring 51 is taken out of the circular groove 57. The staff places the sealing ring 51 on the tool well pipe 1 in the circular groove 57 and rotates the screw 52, which will drive the limit plate 54 to move.

Then the staff can control the flow rate of oil in the pipeline 4 through the valve 2. By setting the protective device 3, after the tool well pipe 1 is installed on the pipeline 4, the staff covers the first protective cover 301 and the second protective cover 302 on the connection between the tool well pipe 1 and the pipeline 4. The first protective cover 301 and the second protective cover 302 will protect the connection between the tool well pipe 1 and the pipeline 4, reduce the corrosion and rust of the fixing bolts 6 fixedly connected between the tool well pipe 1 and the pipeline 4 by rainwater, and effectively improve the stability of the connection between the tool well pipe 1 and the pipeline 4.
[0036] When installing the tool well pipe 1 on the pipeline 4, the damaged sealing ring 51 is taken out from the circular groove 57, and the staff puts the sealing ring 51 on the tool well pipe 1 in the circular groove 57, and then drives the screw 52 to rotate through the handle 53. The screw 52 is driven to rotate by the handle 53, which is convenient for the staff to control the rotation of the screw 52. Rotating the screw 52 will drive the limit plate 54 to move. When the screw 52 drives the limit plate 54 to move, the round rod 55 on the limit plate 54 will guide the limit plate 54 to prevent the limit plate 54 from moving. As the screw 52 rotates, the limit plate 54 moves smoothly, and the cone thorn 56 on the limit plate 54 will pierce the sealing ring 51 to fix the sealing ring 51, which is convenient for the staff to install the tool well pipe 1 on the pipeline 4. By setting the sealing device 5, the sealing ring makes the tool well pipe 1 and the pipeline 4 more tightly sealed when connected. The cone thorn 56 on the limit plate 54 is driven by the screw 52 to move, so that the sealing ring 51 can be quickly replaced during maintenance, which is convenient for the staff to replace the damaged sealing ring 51.
