Description

Technical Field

[0001] The utility model relates to the field of oil production, in particular to oil drilling equipment which is convenient for replacing a drill bit. Background Art

[0002] For oil drilling equipment, the drill bit is one of the most important tools in the drilling process. It is used to penetrate the formation and obtain underground resources. Due to long-term operation in a high temperature, high pressure and high speed environment, the drill bit is prone to wear and damage. Once the drill bit is severely worn or damaged, the drilling efficiency will be significantly reduced. Therefore, easy replacement of the drill bit can ensure that it can be quickly replaced when a problem occurs, thereby maintaining a high drilling efficiency.

[0003] After searching, in the prior art, the Chinese patent with patent announcement number CN215761539U discloses "a drill bit for oil drilling, which relates to the technical field of drill bits. This utility model completes the installation of the drill bit by passing the drill rod and the connecting block through the opening, then rotating the drill bit body so that one side of the connecting block fits with the drill bit body, inserting the limit bolt into the threaded hole to limit the drill bit body, and moving the slide plate so that one side of the slide plate fits tightly with the drill rod, effectively preventing soil from entering the drill bit body", but there are still the following defects:

[0004] 1. The drill bit body is rotated to make one side of the connecting block fit with the drill bit body, and then the limit bolt is inserted into the threaded hole to limit the drill bit body to complete the installation of the drill bit. The installation process is relatively cumbersome, and the diameter of the opening is fixed. When replacing the drill bit, only the drill bit with a fixed diameter can be replaced, which greatly reduces the applicability of drill bit replacement;

[0005] 2. At the same time, limit bolts are inserted into the threaded holes. During the mining process, the drill bit is subjected to great vibrations when running at high speed. The limit bolts may fall off during installation, resulting in unstable installation of the drill bit.

[0006] Therefore, we have made improvements to this and proposed an oil drilling equipment that is easy to replace the drill bit. Utility Model Content

[0007] The purpose of the utility model is to solve the problem that the existing drill bit installation process is relatively complicated, the opening diameter is fixed, and when replacing the drill bit, only the drill bit with a fixed diameter can be replaced, and the drill bit is fixed with a limit bolt, which may fall off due to vibration during mining.
