IMPROVED SEAL FOR A WELL

Номер: US20220034189A1
Принадлежит: Plexus Holdings, PLC

A pressure energised seal for a wellhead, in particular, provides a seal of an annulus between an inner wellhead casing member and an outer wellhead casing member. The wellhead incorporates a clamping arrangement whereby the outer member is arranged to be deflected radially inwardly in order to grip and secure the inner member within the bore of the outer member. Also, a seal for use in such a clamping arrangement. In particular, the seal includes a sealing lip which locates within a groove provided in the outer clamping surface of the inner member. A seal is activated and created as the outer member is clamped inwardly since this causes the outer member to compress the inner member and to reduce the diameter of the inner member. Also, a well and a method of sealing an annulus in a well. 1. A sealing arrangement comprising an inner well casing and a seal for sealing an annulus in a well , the annulus being formed between an outer surface of the inner well casing and an outer well casing of the well wherein the inner well casing comprises:a central longitudinal axis which extends along a longitudinal axis of the inner well casing; andan outer clamping surface which is arranged to be secured and clamped by the outer well casing, the outer clamping surface being located at an initial radial distance from the central longitudinal axis of the inner well casing;the seal comprising:a flexible metal sealing lip which projects radially outwardly and away from the central longitudinal axis of the inner well casing, the metal sealing lip having a distal sealing surface for sealing against an inner surface of the outer well casing; andwherein, in use, pressure within the annulus is arranged to urge the sealing surface towards the inner surface of the outer well casing.2. A sealing arrangement according to claim 1 , wherein claim 1 , prior to use claim 1 , the sealing surface locates at an initial radial distance relative to the central longitudinal axis which is less than or ...

As shown in Figure 1, the present invention provides a pressure energised seal (10) for a wellhead (11) and, in particular, provides a seal (10) of an annulus between an inner wellhead casing member (14) and an outer wellhead casing member (16). The wellhead (11) incorporates a clamping arrangement (22) whereby the outer member (6) is arranged to be deflected radially inwardly in order to grip and secure the inner member (14) within the bore of the outer member (16). The present invention provides an improved seal for use in such a clamping arrangement (22). In particular, the seal (10) includes a sealing lip (12) which locates within a groove provided in the outer clamping surface (15) of the inner member (14). A seal is activated and created as the outer member (16) is clamped inwardly since this causes the outer member (16) to compress the inner member (14) and to reduce the diameter of the inner member (14). This squeezing of the inner member (14) causes the sealing lip (12) to come into contact with the outer member (16) and to be pressed against the outer member (16). This thereby automatically creates a seal as the inner member (14) is clamped by the outer member (16). The normal inherent sealing strength is increased due to the sealing lip (12) being urged to flare (20) outwardly as a result of the pressure within the annulus to be sealed.

Como se muestra en la Figura 1, la presente invención proporciona un sello cargado de energía a presión 10 para una boca del pozo 11 y, en particular proporciona 1n1 obturador 10 de [ni anillo entre un miembro de tubería de revestimiento interior de la boca del pozo 14 y un miembro de tubería de revestimiento exterior de la boca del pozo 16. La boca del pozo 11 incorpora una disposición de sujeción 22 mediante la cual el miembro exterior 16 está dispuesto para ser desviado radialmente hacia el interior a fin de agarrar y asegurar el miembro interior 14 dentro del pozo del miembro exterior 16. La presente invención proporciona un obturador mejorado para su uso en dicha disposición de sujeción 22. En particular, el obturador 10 incluye un borde obturador 12 que se ubica dentro de una acana1adura provista en la superficie de sujeción exterior 15 del miembro interior 14. Un obturador se activa y se crea cuando el miembro exterior 16 se sujeta hacia el interior, ya que hace que el miembro exterior 16 comprima el miembro interior 14 y que reduzca el diámetro del miembro interior 14. Apretar el número interior 14 hace que el borde obturador 12 entre en contacto con el miembro exterior 16 que se prense contra el miembro exterior 16. Esto de este modo crea automáticamente un obturador cuando el miembro interior 14 se sujeta por el miembro exterior 16. La resistencia de obturación implícita normal aumenta debido a que se empuja al borde obturador a ensancharse hacia el exterior como resultado de la presión dentro del anillo que se debe obturar.

La presente invención se relaciona con un tapón de corona 10 para un árbol de un pozo o boca de pozo de petróleo o gas o asociado con él y una disposición de fijación 50 para fijar el tapón de corona 10 dentro del árbol. El cuerpo principal 12 del tapón de corona 10 comprende un cuerpo macizo para crear la barrera dentro del pozo de producción. El cuerpo macizo de ese modo crea una barrera robusta, resistente y confiable. El tapón de corona 10 queda retenido dentro del miembro exterior 30 a través de la distorsión del miembro exterior 30 hacia el interior que agarra y fija el tapón de corona 10 dentro del pozo. La disposición de fijación comprende una disposición de fijación 50 mediante la cual se genera una fuerza radial hacia el interior para distorsionar (desviar o comprimir) un miembro exterior 30 hacia el interior a fin de agarrar un componente ubicado dentro del miembro exterior 30. El miembro exterior 30 se deforma de manera elástica de manera tal que el miembro exterior 30 regrese a una posición liberada una vez que se libere o se retire la fuerza de fijación. En la realización preferida, se disponen dos superficies concéntricas cónicas dispuestas opuestas para moverse axialmente una sobre otra para crear la fuerza dirigida hacia el interior. La combinación de la fuerza de fijación (compresión) junto cxn1 el cuerpo macizó provee una disposición de tapón de corona mejorada que también es fácil y confiable de operar.

Принадлежит: Plexus Ocean Systems Ltd

The present invention relates to a crown plug (10) for a tree of/associated with an oil/gas well/wellhead and a securement arrangement (50) for securing the crown plug (10) within the tree. The main body (12) of the crown plug (10) comprises a solid body to create the barrier within the production bore. The solid body thereby creates a robust, strong and reliable barrier. The crown plug (10) is retained within the outer member (30) through the distortion of the outer member (30) inwardly which thereby grips and clamps the crown plug (10) within the bore. The securement arrangement comprises a clamping arrangement (50) by which an inward radial force is generated in order to distort (deflect/compress) an outer member (30) inwardly in order to grip a component located within the outer member (30). The outer member (30) is elastically deformed such that the outer member (30) will return to a released position once the clamping force is released/removed. In the preferred embodiment, two concentric oppositely arranged tapered surfaces are arranged to move axially over each other to create the inwardly directed force. The combination of the clamping (squeeze) securing force together with the solid body provides an improved crown plug arrangement which is also easy and reliable to operate.
