Abstract

FERRAMENTA DE PERFURAÇÃO, E, MÉTODO PARA OPERAR UMA PERFURAÇÃO FURO ABAIXO Uma broca rotativa de assistência percussiva inclui um sub de topo para conexão com um tubo de perfuração. O tubo de perfuração transmite torque para a broca e também provê fluido motriz para a broca. A broca inclui um adaptador de haste para facilitar a aposição de uma broca de perfuração rotativa à broca. O fluido motriz é dividido entre um fluxo de broca, que flui através da broca para limpar detritos no fundo da perfuração, e um fluxo de atuador. Um atuador, que pode ser na forma de um pistão alternado, se move dentro da perfuração sob a influência do fluxo de atuador para transmitir golpes cíclicos ao adaptador de haste. Os golpes são transferidos para a broca de perfuração por meio do adaptador de haste para prover uma frequência relativamente alta de força de percussão de baixa amplitude sobre a broca de perfuração rotativa para ajudar na operação de perfuração. Pelo menos um porção da porção de fluxo de atuador do fluido motriz é expelida através da extremidade de topo da broca. As vazões e volumes relativos dos fluxos de broca e de atuador podem ser ajustados com uma válvula de retenção no trajeto de exaustão do fluxo de atuador.
