Description

Technical Field

[0001] The utility model relates to the technical field of drilling, in particular to a drilling support for oil drilling. Background Art

[0002] The work of drilling holes in the ground using mechanical equipment or manpower is called drilling. The diameter and depth of the well depend on the purpose of drilling and the burial depth of the mineral. The completion of each well includes three stages: pre-drilling engineering, drilling engineering and completion operations. Each engineering stage has a series of construction processes. The main processes generally include: well positioning, road survey, foundation construction, derrick installation, moving, equipment installation, primary drilling, secondary drilling, drilling, pulling out the drill, changing the drill bit, drilling, completion, electrical measurement, casing installation, cementing operations, etc.

[0003] When optimizing the existing drilling supports for oil drilling, most of them are reflected in optimizing the convenience of wellhead support installation and the stability and anti-tilting after installation. For example, the Chinese utility model patent with application number CN202121745787.6 discloses "An adjustable assembled wellhead support for oil drilling". In this device, the installation is more convenient and easy to adjust through the anti-side tilting rope, and the anti-slip rubber gasket on the inside of the circular metal sleeve is tightly squeezed on the hydraulic drive seat. The height of the circular metal sleeve on the hydraulic drive seat is adjusted by the height of the telescopic round rod. When the telescopic round rod rises to a higher height, the circular metal sleeve should be placed at a higher position of the hydraulic drive seat. Similarly, when it is lower, it should be sleeved at a lower position. Due to the different rising heights of the telescopic round rod, the hydraulic drive seat will be subjected to different forces. When the force increases, the equipment boom will tilt, and the steel wire ropes on both sides of the lower end of the circular metal sleeve are fixed to the body through fixed metal blocks, so that the hydraulic drive seat can balance the force while resisting the gravity of the wind and the suspended object to prevent the danger of tilting.

[0004] Although the above-mentioned drilling support for oil drilling has certain advantages in preventing the support from tilting and avoiding danger, it still has certain disadvantages: the support legs, as the main supporting structure of the support legs, are installed under the flat frame. After the drilling operation is completed, the support legs and the flat frame are still arranged at 90 degrees, which is not convenient for the storage and transportation of the support legs. Moreover, if it is necessary to replace the support legs of different specifications, the support legs and the flat frame are welded, which is not convenient for disassembly and replacement of the support legs.
