Problems solved by technology

[0002] During the continuous development of oil and gas fields, some oil, gas and water wells have been shut down for a long time (more than one year) because they cannot meet the normal production needs, and more and more wells will be scrapped due to geological, engineering or other reasons. In relatively remote areas, the management of the oil production team is negligent, there is no permanent seal, and there is no anti-theft. Once the crude oil spills, the environment will be polluted, causing accidents, causing irreparable losses, and adversely affecting the corporate image.
[0003] At present, the anti-theft cement cap is poured with reinforced concrete to form an anti-theft device, which is extremely cumbersome, and cranes and other lifting equipment must be used when moving, measuring and releasing pressure. The implementation process requires a lot of manpower and equipment, and the construction is cumbersome and complicated; The wellhead is welded to death, so that the work of collecting pressure and sealing the packing needs to be completed by electric welding and cutting. This method is cumbersome and unsafe. During gas welding and cutting, natural gas is prone to fire or explosion, which is likely to cause personal injury accidents and property loss

Abstract

The invention provides a well head anti-theft well lid. The well head anti-theft well lid comprises a well lid body 1, a fixed hole 2, a fixing piece 3, an inserting rod fixing piece 4, an inserting rod 5, a lock seat 6, a first handle 7, a second handle 8 and a third handle 9. The well head is jointly protected by the above components, the two ends of the inserting rod 5 are separately provided with protective covers 10 suitable for the fixing piece 3, and the length of the inserting rod 5 is a certain distance beyond the length of the well lid 1. It is impossible to open the fixing piece 3 protected by the protective covers 10 and the well lid 1 without opening an externally-arranged lock to steal crude oil. The well head anti-theft well lid is simple in structure, convenient to install,convenient to operate and high in anti-theft ability.
