Abstract

"BROCA DE PERFURAçãO DE PERCUSSãO PARA PERFURAR EM UMA FORMAçãO GEOLóGICA SUBTERRáNEA, E, SISTEMA DE PERFURAçãO E MéTODO PARA PERFURAR UM FURO DE SONDAGEM EM UMA FORMAçãO GEOLóGICA". Uma broca de perfuração de percussão para perfurar em uma formação geológica subterrânea, a broca de perfuração tendo um eixo longitudinal central e sendo operável pela aplicação de movimento percussivo axial ao longo do eixo e movimento rotativo ao redor do eixo, a broca de perfuração compreendendo: uma pluralidade de lâminas (61, 62, 63) se projetando da broca de perfuração; uma pluralidade de canais de fluxo (71, 72, 73) estendendo-se ao longo da broca de perfuração em uma direção substancialmente radial, por meio do que os sucessivos canais de fluxo são formados entre duas lâminas adjacentes; cortadores cisalhantes (9) que são providos em uma fileira ou próximo à borda traseira de pelo menos uma das mencionadas lâminas com respeito à direção de movimento de rotação sucessivo adjacente ao canal de fluxo que está associado a ela, para escoar um fluido transpassante e, desse modo, remover detritos de corte acumulados na frente da fileira de cortadores cisalhantes; e, em adição, a estes cortadores cisalhantes; e, em adição a estes cortadores cisalhantes, cortadores axiais (10, 11) que são localizados, com respeito à direção do movimento rotativo, em uma posição traseira com respeito à mencionada fileira de cortadores cisalhantes e seu canal de fluxo associado."DRILLING DRILL DRILL TO DRILL IN AN UNDERGROUND GEOLOGICAL FORMATION, AND DRILLING SYSTEM AND METHOD FOR DRILLING A DRILL DRILL IN A GEOLOGICAL FORMATION". A percussion drill bit for drilling in an underground geological formation, the drill bit having a central longitudinal axis and being operable by applying axial percussive motion along the axis and rotary movement around the axis, the drill bit comprising: a plurality of blades (61, 62, 63) protruding from the drill bit; a plurality of flow channels (71, 72, 73) extending along the drill bit in a substantially radial direction whereby successive flow channels are formed between two adjacent blades; shear cutters (9) which are provided in a row or near the rear edge of at least one of said blades with respect to the direction of successive rotation of movement adjacent to the associated flow channel to flow a passing fluid and, thereby removing accumulated cutting debris in front of the row of shear cutters; and in addition to these shear cutters; and, in addition to these shear cutters, axial cutters (10, 11) which are located with respect to the direction of rotary movement in a rearward position with respect to said row of shear cutters and their associated flow channel.
