Abstract

Se describe un aparato obturador 2 para proporcionar un sello anular en un pozo de perforación. El aparato obturador 2 comprende un cuerpo 4 que define un primer orificio 6 para permitir que el fluido de trabajo tal como el fluido de la fracturación hidráulica que contiene el agente de sostén fluya a través del aparato obturador. Un primer canal 8 se forma en el cuerpo y se dispone para sostener el fluido hidráulico. Un primer pistón flotante 10 está dispuesto en el primer canal, el primer pistón flotante que está en comunicación fluida con el primer orificio 6 a través de un pasaje 12. Una pluralidad de pistones 18 está dispuesta para mover el miembro de activación 14 con relación al cuerpo para deformar el elemento obturador elastomérico 16 hacia fuera con relación al cuerpo.A sealing apparatus 2 for providing an annular seal in a borehole is described. The sealing apparatus 2 comprises a body 4 defining a first hole 6 to allow the working fluid such as the hydraulic fracturing fluid containing the support agent to flow through the sealing apparatus. A first channel 8 is formed in the body and is arranged to hold the hydraulic fluid. A first floating piston 10 is arranged in the first channel, the first floating piston that is in fluid communication with the first hole 6 through a passage 12. A plurality of pistons 18 is arranged to move the activation member 14 relative to the body to deform the elastomeric sealing element 16 outwardly relative to the body.
