Abstract

The invention provides a diamond geological drill bit capable of being subjected to cooling and chip removing, and relates to the field of drill bits. The diamond geological drill bit capable of beingsubjected to cooling and chip removing comprises a connecting piece, a drill bit body is arranged at the upper end of the connecting piece, a cavity is formed in the drill bit body, an impact hammeris arranged in the cavity, the impact hammer extends out of the upper end of the drill bit body, the impact hammer comprises an impact main body, a third water channel is formed in the impact main body, a water outlet is formed in the side wall of the upper end of the impact main body, a water inlet is formed in the lower end of the impact main body, the water inlet communicates with the water outlet through the third water channel, a baffle is arranged in the water inlet, a sealing gasket is fixedly connected to the upper end face of the baffle and close to the third water channel, and a flowguide hole is formed in the middle of the baffle. According to the drill bit, by means of a water hammer effect, the drilling speed is increased, and meanwhile the advantages of cooling and chip removing are achieved.

Description

technical field [0001] The invention relates to the technical field of drill bits, in particular to a diamond geological drill bit capable of cooling the drill bit and removing chips. Background technique [0002] The drill bit is the main tool for breaking rock during the drilling process, and the wellbore is formed by breaking the rock with the drill bit. The quality of a wellbore formation and the length of time it takes are not only related to the characteristics of the drilled formation rock and the performance of the drill bit itself, but also to the degree of matching between the drill bit and the formation. The reasonable selection of the drill bit plays an important role in increasing the drilling speed and reducing the overall cost of drilling. At present, there are many types of drill bits used in the petroleum industry. The drill bits are classified according to different drilling methods. They can be divided into diamond drill bits, roller cone bits and scraper...
