Abstract

The invention discloses a drill bit cooling device, comprising a drill bit main body connected with a drill rod; a cooling through hole is formed in the drill bit main body; an inlet and an outlet are formed in the cooling through hole; a liquid inlet pipe and a liquid outlet pipe are arranged in the drill rod; one end of the liquid inlet pipe is connected with the inlet, and the other end of the liquid inlet pipe is connected with a water pump; the water pump is connected with one end of a liquid drainage main pipe; the other end of the liquid drainage main pipe is uniformly connected with certain ends of N heat dissipation branch pipes; the other ends of the N heat dissipation branch pipes are all connected with one end of the liquid outlet pipe; the other end of the liquid outlet pipe is connected with the outlet, wherein the N heat dissipation branch pipes are all located in a water tank; the water tank is provided with a water inlet and a water outlet so as to supply water circularly; a thermometer is arranged in the water tank. The technical effects that the drill bit has a relatively good cooling effect, relatively long service life and relatively high working efficiency are realized.

Description

technical field [0001] The invention relates to the field of petroleum machinery research, in particular to a drill bit cooling device. Background technique [0002] The abbreviation of diamond compact (PDC) drill bit is a drilling tool commonly used in the oil drilling industry. [0003] The performance of PDC products continues to improve. Over the past few years, the quality and type of PDC cutting teeth have changed dramatically. If you compare the teeth of the 1980s with today's teeth, the difference is considerable. Due to the mixing Due to the changes in technology and manufacturing process, the quality and performance of today's cutting teeth are much better, which greatly improves the erosion resistance and impact resistance of the drill bit. [0004] Engineers also optimized the interface between the tungsten carbide substrate and the synthetic diamond to increase the toughness of the cutting teeth. Innovations in layered diamond processing have also been used to...
