Description

Technical Field

[0001] The utility model relates to the technical field related to oil exploitation, in particular to a ventilation pipeline used in oil exploitation. Background Art

[0002] Oil extraction refers to the act of digging and extracting oil from where it is stored. In the process of oil extraction, oil and gas flow from the reservoir to the bottom of the well, and then rise from the bottom of the well to the wellhead. In the process of oil extraction, there will be harmful gases and flammable gases underground. This gas cannot be directly absorbed by the human body. At the same time, this gas may also cause certain damage to the mining site during extraction. For example, it may cause sparks when the drilling rig drills down to extract oil, causing underground explosions and collapses. Therefore, we need to discharge and reasonably treat the underground harmful gases and flammable gases. Therefore, a ventilation duct for oil extraction is particularly needed.

[0003] However, the existing ventilation ducts used in oil extraction are too bulky, which is not conducive to transportation and disassembly. There is no way to quickly disassemble and install them, which greatly increases the workload of oil extraction. After the extraction, a large amount of manpower is required to dismantle the ducts, which will increase the labor cost expenditure. Utility Model Content

When it slides to a suitable position and is fixed, the first limiting ring 206 and the ventilation duct 205 are threadedly connected. Then, the upper and lower ventilation ducts 205 are threadedly connected along the circular groove formed by the supporting block 202 through the threaded groove 209. At this time, the fixing ring 207 and the first limiting ring 206 will press against the supporting block 202 to fix it in position.

[0021] Furthermore, the inner surface of the slot 204 and the outer surface of the block 203 fit together, and four groups of support blocks 202 are arranged on the outside of the ventilation duct 205.
