Abstract

método e aparelho para perfurar um furo de sondagem. é descrito um método de perfurar um furo de sondagem subterrâneo compreendendo: a) bombear um fluido de perfuração abaixo em uma coluna de perfuração, a coluna de perfuração tendo uma broca de perfuração em uma extremidade da mesma; b) girar a coluna de perfuração em torno de seu eixo longitudinal para que essa broca forme o furo de sondagem no terreno, o método compreendendo adicionalmente as etapas de: c) mudar a taxa de bombeamento do fluido de perfuração pelo interior da coluna de perfuração em resposta a uma mudança na velocidade de rotação da coluna de perfuração; e/ou mudar a velocidade de rotação da coluna de perfuração em resposta a uma mudança na taxa de bombeamento do fluido de perfuração pelo interior da coluna de perfuração.
