Abstract

BROCA E SISTEMA DE PERFURAÇÃO. A presente invenção refere-se a uma broca de perfuração para formar um orifício em uma formação. A broca de perfuração tem uma haste e uma coroa anular que cooperam para definir um espaço interno que recebe água ou outro fluido de perfuração. A coroa anular define canaletas internas espaçadas circunferencialmente ao redor de uma superfície interna da coroa e canaletas externas espaçadas circunferencialmente ao redor de uma superfície externa da coroa. A coroa anular pode encerrar de modo circunferencialmente completo o espaço interno da broca, ou a coroa anular pode ser dotada de uma única canaleta para água estendendo-se entre as superfícies interna e externa da coroa.DRILL AND DRILLING SYSTEM. The present invention relates to a drill bit for forming a hole in a formation. The drill bit has a shank and an annular crown that cooperate to define an internal space that receives water or other drilling fluid. The annular crown defines inner grooves spaced circumferentially around an inner surface of the crown and outer grooves spaced circumferentially around an outer surface of the crown. The annular crown may circumferentially completely enclose the internal space of the drill, or the annular crown may be provided with a single water channel extending between the inner and outer surfaces of the crown.
