Abstract

The invention relates to the technical fields of petroleum and natural gas, mine engineering, geothermal wells, building foundation engineering construction, geology and hydrological drilling, in particular to a diamond drill bit with a high-efficiency water hole structure. According to the diamond drill bit, a rear water spray hole seat extending to a drill bit body or connected to the drill bitbody is arranged in front of at least one of cutter wings, the rear water spray hole seat is provided with a rear water spray hole communicating with a flow channel in the drill bit, and the rear water spray hole can directly spray water onto cutting teeth on the cutter wings or rocks in front of the cutting teeth. According to the diamond drill bit with the high-efficiency water hole structure, the cutting teeth are fully cooled and cuttings are transported in time in high temperature well drilling, and the drilling performance of the drill bit is greatly improved.

Description

[0001] Technical field:

[0002] The invention relates to the technical fields of petroleum and natural gas, mining engineering, geothermal wells, building foundation engineering construction, geology, and hydrological drilling, in particular to a diamond drill bit with a high-efficiency water hole structure.

[0003] Background technique:

[0004] The drill bit is a rock-breaking tool used in drilling engineering to break rock and form a wellbore. In addition to the cutting structure, the hydraulic structure on the drill bit also plays an important role in the rock-breaking efficiency and service life of the drill bit, that is, cooling the cutting teeth, cleaning the bottom of the well, transporting cuttings, and assisting in rock breaking. At present, the design of the hydraulic structure on the drill bit is to arrange nozzles or water holes (water holes) at different positions on the drill bit body, and the drilling fluid or cooling medium in the inner flow channel is spraye...
