Abstract

aparelho de perfuração rotativa, e, conjunto de pistão para uso juntamente com uma seção de direcionamento de um aparelho de perfuração rotativa direcionável. aproximadamente, de perfuração direcionável inclui um sistema de controle no interior de um alojamento cilíndrico conectado a uma broca de perfuração tendo pistões radialmente extensíveis. um fluido de atuação de pistão escoa do alojamento e através de um conjunto de medição de fluido que direciona o fluido para canais de fluido na borca de perfuração conduzindo aos respectivos pistões. o sistema de controle controla o conjunto de medição de fluido para seletivamente permitir que o fluido escoe através dos canais de fluido para os pistões e saia através de um orifício em cada canadl de fluido. o fluxo de fluido seletivo faz com que os pistões na broca de perfuração se estendam temporariamente na direção oposta a um desvio desejado de perfuração de poço, defletindo-a, desse modo, da linha central do furo perfurado. o conjunto de medição de fluido tem a capacidade de estabilizar, direcionar e mudar tfa dentro da broca de perfuração por mover um membro de suporte dentro do conjunto de medição de fluido. o sistema de controle e a broca de pefuração se conectam de maneira específica para facilitar a remoção, para a mudança da seção de direcionamento da broca de perfuração e configuração ou calibre de estrutura de corte simultaneamente.
