Abstract
"DIREçãO DE CABEçOTE DE PERFURAçãO". A presente invenção refere-se a um método de direcionar um cabeçote de perfuração de fluido em uma situação de perfuração de furo de sondagem subterrâneo rodando a mangueira flexível através da qual alta pressão é fornecida no cabeçote de perfuração e fornecendo uma força de orientação no cabeçote de perfuração. A mangueira pode ser rodada de uma situação montada de superfície remota rodando a armação de superfície inteira (13) em um plano horizontal em torno de uma base giratória (24) fazendo a parte verticalmente orientada da mangueira (11) rodar em torno de seu eixo longitudinal. A força de inclinação pode ser fornecida em um número de maneiras diferentes mas resulta tipicamente do uso de um anel de calibração assimétrico no cabeçote de perfuração de fluido.
