Description

Technical Field

[0001] This utility model relates to the field of oil well technology, specifically an anti-theft and oil wellhead device. Background Technology

[0002] An oil well is an engineering facility that forms a wellbore by drilling, running in casing and cementing, and then completing the well through perforation or open hole to create a channel connecting the underground oil layer to the surface. It is used to extract crude oil from the formation to the surface. Its working principle depends on formation pressure or artificial lift energy. When the formation energy is insufficient, the energy is artificially supplemented by pumping (such as pumping units or electric submersible pumps) or gas lift to lift the crude oil to the surface.

[0003] Regarding the above and existing related technologies: During oil extraction, it is necessary to install oil wells at the oilfield. Since oil extraction is carried out outdoors, and most oil wells are fixed to their outdoor structures via flange connections, and most oil wells are left unattended after installation, this can easily lead to problems such as the well body being bumped or struck by animals during actual use. Therefore, an anti-theft and oil wellhead device is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The anti-theft and oil wellhead equipment of this utility model includes a well body and a protective device. Multiple valves are fixedly connected to the surface of the well body. The protective device is set on the surface of the well body and includes two protective covers. The two protective covers are fitted onto the surface of the well body. Multiple fixing blocks are fixedly connected to the surface of the two protective covers. Two fixing blocks that are close to each other form a group. The inner surface of each group of fixing blocks is threaded with an anti-theft bolt. A handle is fixedly connected to the ends of the two protective covers that are far apart from each other. The protective covers are fitted onto the surface of the well body, and then the anti-theft bolts are installed on the two fixing blocks. By setting the protective covers, the well body can be protected, and the anti-theft capability of the well body can also be increased.

[0006] Preferably, the surface of the protective cover is provided with a storage groove, and the well body is inserted into the inner surface of the storage groove of the protective cover. When the protective cover moves, the protective cover will be fitted onto the surface of the well body through the storage groove. The opening of the storage groove makes it convenient for the protective cover to be fitted onto the surface of the well body.

[0007] Preferably, the bottom end of the protective cover is fixedly connected to two support frames, and the inner surface of the support frames is rotatably connected to two support wheels. The support frames drive the support wheels to roll on the ground. By setting the support frames and support wheels, the protective cover can be moved to a convenient position.

[0008] Preferably, two reinforcing rods are fixedly connected to both sides of the support frame and the bottom of the cover. When the support frame is under force, the support frame will transfer the force to the reinforcing rods, which can increase the strength of the support frame.

[0009] Preferably, two reinforcing frames are fixedly connected to the surface of the protective cover. When the protective cover is in use, the protective cover will transfer the force to the reinforcing frames, which can increase the strength of the protective cover.

[0010] Preferably, the side wall of the protective cover is provided with three heating devices. Each heating device includes a frame, the side wall of the frame is fixedly connected to the side wall of the protective cover, the surface of the protective cover is covered with a storage plate, and an electric heating plate is inserted into the inner surface of the storage plate. The storage plate is placed on the surface of the frame, and then the electric heating plate is activated to heat the well body. By setting the frame, storage plate and electric heating plate, the well body can be heated.

[0011] Preferably, both sides of the frame are fixedly connected with locking blocks, and both sides of the storage plate are fixedly connected with two placement blocks. Insert rods are inserted into the inner walls of the two placement blocks and the inner walls of the locking blocks. When the insert rods are inserted into the inner walls of the two placement blocks and the inner walls of the locking blocks, the insert rods, locking blocks and placement blocks can fix the position of the storage plate.

[0012] The advantages of this utility model are:

[0013] 1. After the well body and valve are installed, this utility model allows you to move the protective cover by holding and pushing the handle. The handle will move the protective cover, which in turn moves the support frame. The support frame will then cause the support wheels to roll on the ground. When the protective cover moves, it will fit over the surface of the well body through the storage groove. Then, the anti-theft bolts are installed on the two fixed blocks. When the protective cover is under stress, the force will be transmitted to the reinforcing frame. When the support frame is under stress, the force will be transmitted to the reinforcing rod. By setting up the entire device, the well body can be protected, reducing the direct impact to the well body. At the same time, it can also prevent the well body from being stolen, reducing the possibility of the well body being stolen.
