Abstract

descriptive abstract a device for controlling and isolating a tool in the form of an expansible sleeve for isolating areas in a well the present invention relates to a device for controlling and isolating a tool (3) for isolating areas in a well (1) which comprises: - a main inlet conduit (c) which communicates with the inside of said casing (2), and which is obturated by a first element (5) able to form a barrier to a fluid circulating in said casing (2), while yielding beyond a first pressure (p1), - this conduit (c) communicating, with two auxiliary conduits (6, 8), the ends of which join up in order to form an outlet conduit (9), - one (8) of these auxiliary conduits, forming a first chamber, while, in the other one (6), a second element (7) is provided forming a barrier, moveable between a first position and a second position characterized by the fact that in said first position, said second element (7) forming a barrier and the wall (630) of said second auxiliary conduit (6) make between them a sealed annular chamber (ch2) in which prevails a so-called " isolation " pressure (pis), this chamber (ch2) not communicating with the outside, notably with the well (1). -------------------------------------------------------------------------------------------- tradução do resumo resumo patente de invenção: "dispositivo para controlar e isolar uma ferramenta sob a forma de uma luva expansível para isolar áreas em uma cavidade". a presente invenção refere-se a um dispositivo para controlar e isolar uma ferramenta (3) para isolar áreas em uma cavidade (1) que compreende: - um conduíte de entrada principal (c) que se comunica com o interior do dito compartimento (2), e que é obturado por um primeiro elemento (5) capaz de formar uma barreira a um fluido que circula no dito compartimento (2), enquanto rende além de uma primeira pressão (p1); - esse conduíte (c) se comunica com dois conduítes auxiliares (6, 8), as extremidades dos quais se unem a fim de formar um conduíte de saída (9); - um (8) desses conduítes auxiliares que forma uma primeira câmara, enquanto, no outro (6), um segundo elemento (7) é fornecido que forma uma barreira móvel entre uma primeira posição e uma segunda posição, caracterizado pelo fato de que na dita primeira posição, o dito segundo elemento (7) que forma uma barreira e a parede (630) do dito segundo conduíte auxiliar (6) fazem entre eles uma câmara anular vedada (ch2) na qual prevalece uma então chamada pressão de isolamento (pis), essa câmara (ch2) que não se comunica com o exterior, particularmente, com a cavidade (1).descriptive abstract a device for controlling and isolating a tool in the form of an expandable sleeve for isolating areas in a well the present invention relates to a device for controlling and isolating a tool (3) for isolating areas in a well (1) which comprises : - a main inlet conduit (c) which communicates with the inside of said casing (2), and which is obturated by a first element (5) able to form a barrier to a fluid circulating in said casing (2), while yielding beyond a first pressure (p1), - this conduit (c) communicating, with two auxiliary conduits (6, 8), the ends of which join up in order to form an outlet conduit (9), - one (8) of these auxiliary conduits, forming a first chamber, while in the other one (6), a second element (7) is provided forming a barrier, moveable between a first position and a second position characterized by the fact that in said first position, said second element (7) forming a barrier and the wall (630) of said second auxiliary conduit (6) make between them a sealed annular chamber (ch2) in which prevails a so-called "isolation" pressure (pis), this chamber (ch2) not communicating with the outside, notably with the well (1). -------------------------------------------------- ------------------------------------------ Translation of summary patent summary: "Device for controlling and isolating a tool in the form of an expandable sleeve for isolating areas in a cavity." The present invention relates to a device for controlling and isolating a tool (3) for isolating areas in a cavity (1) comprising: - a main inlet conduit (c) communicating with the interior of said housing (2) ), and which is closed by a first element (5) capable of forming a barrier to a fluid circulating in said compartment (2), while yielding beyond a first pressure (p1); - this conduit (c) communicates with two auxiliary conduits (6, 8), the ends of which join together to form an outlet conduit (9); - one (8) of these auxiliary conduits forming a first chamber, while in the other (6) a second element (7) is provided that forms a movable barrier between a first position and a second position, characterized in that in the said first position, said second barrier forming member (7) and the wall (630) of said second auxiliary conduit (6) make between them a sealed annular chamber (ch2) in which a so-called insulating pressure (pis) prevails. ), that chamber (ch2) which does not communicate with the outside, particularly with the cavity (1).
