Abstract

"ESCAREADOR PARA USO NA FORMAçãO DE UM POçO PERFURADO ATRAVéS DE UMA FORMAçãO GEOLóGICA, CONJUNTO DE PERFURAçãO PARA FORMAR UM POçO PERFURADO, CONJUNTO DE PERFURAçãO PARA CORTAR UM POçO EM FORMAçãO GEOLóGICA, FERRAMENTA DE FUNDO DE POçO PARA USO EM UM CONJUNTO DE PERFURAçãO EM UM POçO PERFURADO, MéTODO PARA PASSAR UM CONJUNTO DE PERFURAçãO ATRAVéS DE UM POçO PERFURADO EXISTENTE TENDO UM DADO DIâMETRO E PERFURAR UM NOVO POçO SOB O POçO PERFURADO EXISTENTE, MéTODO PARA ESCAREAR UM POçO PERFURADO, E, CONJUNTO DE PERFURAçãO PARA PERFURAR UM POçO ATRAVéS DE FORMAçãO GEOLóGICA". Um conjunto de perfuração e um escareador excêntrico de diâmetro ajustável são revelados. O escareador inclui elementos cortantes montados sobre pelo menos uma lâmina fixa para escarear um poço perfurado previamente formado ou para formar um poço perfurado de maior diâmetro sob um poço perfurado revestido existente. O método e aparelho provêem estabilizar o conjunto de perfuração de modo que o escareador possa ser usado no retroescareamento do furo. Meios de retenção, como pinos de cisalhamento ou membros de travamento reciprocantes solicitados por mola são providos para impedir extensão prematura dos membros móveis do escareador, incluindo lâminas e pistões. Os pinos de cisalhamento são, de preferência, acessíveis pela superfície externa do alojamento do escareador de modo a facilitar substituição no campo dos pinos de cisalhamento sem precisar desmontar o escareador. Os membros de travamento solicitados por mola travam e destravam repetidamente, de modo que a substituição no campo não seja necessária e, assim, os membros móveis podem ser estendidos e contraídos múltiplas vezes enquanto o escareador estiver no interior do poço.
