Abstract

The invention provides a multifunctional diamond drill bit and a working principle thereof. The multifunctional diamond drill bit comprises a connector, a threaded cavity, a drill bit main body, a connecting block, a first connecting hole, a second connecting hole, an extending drill rod structure, a connecting fixing rod structure and a rotating ring structure, wherein the threaded cavity is formed in the lower surface of the connector; the drill bit main body is welded at the top of the connector; and the connecting block is arranged at the upper surface of the drill bit main body through injection molding. Through the arrangement of the extending drill rod structure, during the hole drilling, the diameter of a drill hole can be conveniently enlarged, and meanwhile, the functions of thediamond drill bit are also added; through the arrangement of the connecting fixing rod structure, the diamond drill bit can be conveniently reinforced, and meanwhile, the connecting modes of the diamond drill bit are also added; through the arrangement of the rotating ring structure, the length of the rotating ring structure can be conveniently extended; and meanwhile, during the installation of the diamond drill bit, the fastening performance of the diamond drill bit can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of drilling, and in particular relates to a multifunctional diamond drill bit. Background technique [0002] When digging and drilling wells, when encountering rock formations, diamond bits are most suitable, especially one-piece diamond bits, the whole bit has no moving parts, the structure is relatively simple, and it has high strength, high wear resistance and impact resistance. , is one of the three new technologies of drilling in the world in the 1980s. When drilling in soft-medium hard formations, the diamond drill bit has the advantages of fast speed, large footage, long life, stable work, few downhole accidents, and good wellbore quality. advantage. The diamond drill bit not only has a long service life, but also can be reused. The diamond drill bit returned to the factory for repair has the same effect as the factory diamond drill bit, which can save a lot of drilling costs. [0003] However, the ...
