Abstract

é descrita uma ferramenta de corte (1) para ampliação do diâmetro de um furo de sondagem e método da mesma. a ferramenta de corte (1) compreende um alojamento (2) tendo cavidade (10) no qual um elemento de ativação móvel (6) é arranjado. o elemento de ativação (6) é movido em uma direção axial e está conectado a um ou mais blocos de corte por meio de um acoplamento mecânico (15). o acoplamento mecânico (15) transfere o movimento axial do elemento de ação em um movimento radial dos blocos de corte. uma unidade de ativação (24) empurra o elemento de ativação (6) em direção a uma posição de parada que, por sua vez, faz com que os blocos de corte (11) se movem para fora do alojamento. a unidade de ativação (24) puxa ainda o elemento de ativação de volta em direção a sua posição de partida que, por sua vez, faz com que os blocos de corte se movam de volta para o alojamento. os blocos de corte (11) se estendem para um ou mais cavidades formadas no elemento de ativação, aumentando assim a relação deslocamento-expansão. os blocos de corte podem ser substituídos pelas lâminas estabilizadoras (20) que são usadas para estabilizar a perfuração no furo de sondagem expandido.A cutting tool (1) for enlarging the diameter of a borehole and its method is described. The cutting tool (1) comprises a housing (2) having cavity (10) in which a movable activation element (6) is arranged. The activation element (6) is moved in an axial direction and is connected to one or more cutting blocks by means of a mechanical coupling (15). The mechanical coupling (15) transfers the axial movement of the action element into a radial movement of the cutting blocks. an activating unit (24) pushes the activating element (6) towards a stop position which in turn causes the cutting blocks (11) to move out of the housing. The activation unit (24) further pulls the activation element back towards its starting position which in turn causes the cutting blocks to move back into the housing. the cutting blocks (11) extend into one or more cavities formed in the activation element, thereby increasing the displacement-expansion ratio. The cutting blocks can be replaced by the stabilizer blades (20) which are used to stabilize the drilling in the expanded drillhole.
