Abstract

"APARELHO E OPERAçãO DE PERFURAçãO". O aparelho de perfuração inclui uma junta de segurança que pode ser montada à extremidade externa da coluna de perfuração para reter a combinação de um conjunto de elevação vertical e um adaptador de elevação vertical que se estende dentro da extremidade externa da coluna de perfuração durante uma operação de perfuração, e que impede a ferramenta de perfuração se mover para fora da coluna de perfuração até que a junta seja removida. O conjunto de elevação vertical tem uma vedação a fluido entre o tubo de elevação vertical e a coluna de perfuração e um canal de contorno de fluido com o dispositivo de válvula para bloquear o fluxo axial para fora através do canal quando o adaptador de elevação vertical é separado do conjunto de elevação vertical e, quando conectado a ele, reter o dispositivo de válvula em uma condição aberta. Quando o adaptador de elevação vertical é removido do conjunto de elevação vertical, o conjunto de elevação vertical pode ser impelido fluidamente para a extremidade da broca. Uma ferramenta de desconexão facilita a remoção do adaptador da junta."DRILLING EQUIPMENT AND OPERATION". The drill includes a safety joint that can be mounted to the outer end of the drill string to retain the combination of a vertical lift assembly and a vertical lift adapter that extends within the outer end of the drill string during an operation. that prevents the drilling tool from moving out of the drill string until the joint is removed. The vertical lift assembly has a fluid seal between the vertical lift pipe and drill string and a fluid bypass channel with the valve device to block axial flow outward through the channel when the vertical lift adapter is separate from the vertical lift assembly and, when connected to it, retain the valve device in an open condition. When the vertical lift adapter is removed from the vertical lift assembly, the vertical lift assembly may be driven fluidly to the drill end. A disconnect tool facilitates removal of the gasket adapter.
