Abstract

"SISTEMA DE PERFURAçãO, E MéTODO PARA PERFURAR UM FURO DE SONDAGEM". Um sistema de perfuração para perfurar um furo de sondagem em um terreno em uma formação subterrânea em terra, o sistema de perfuração compreendendo: uma coluna de perfuração (112) que se estende para o interior do furo de sondagem, pelo que, um espaço anelar é formado entre a coluna de perfuração e a parede do furo de sondagem, a coluna de perfuração incluindo uma passagem longitudinal de fluido de perfuração que tem uma abertura de saída na parte extrema inferior da coluna de perfuração; uma bomba (138) para bombear um fluido de perfuração a partir de uma fonte de fluido de perfuração através da passagem longitudinal de fluido de perfuração para o interior do espaço anelar; um conduto de descarga de fluido (124) em comunicação fluida com dito espaço anelar para descarregar dito fluido de perfuração; o sistema de contra pressão de fluido (131, 132, 133) em comunicação fluida com dito conduto de descarga de fluido; dito sistema de contra pressão de fluido compreendendo um conduto de desvio (7) e uma válvula de três vias (6) fornecida entre a bomba e a passagem longitudinal de fluido de perfuração, pelo que, a bomba está em comunicação fluida com o conduto de descarga de fluido (124) através da válvula de três vias e do conduto de desvio que desvia no mínimo parte da passagem longitudinal de fluido.
