    [0001] This order claims the benefit of US Order No. 12/956781, filed on November 30, 2010, which is incorporated herein by reference in its entirety. BACKGROUND
    [0002] In the well drilling and completion industry, elastomeric seals are used to seal annular areas between concentric tubulars. The extrusion of such seals is a well-known problem in the well industry for which several solutions have been proposed. Due to the infinite number of possible specific applications, however, the technique is always looking for additional methodologies and configurations to combat extrusion.
    [0003] US 2004069502, for example, describes a method and apparatus for sealing a tubular. The device is a sealing device for a downhole tool, such as a bridge plug, packer or fracture plug. In one embodiment, US 2004069502 provides a sealing apparatus having a body and a sealing system arranged around the body.
    [0004] US5678635 discloses a downhole compression adjustment bridge plug and a method to be used to obstruct a tubular disposed in a downhole. For this purpose, the method allows the bridge plug to be drilled down the hole through a small diameter tubular and then to define the bridge plug inside a large diameter tubular. The large diameter tubular may have the lower end of the small diameter tubular supported thereon. The method generally includes connecting the downhole bridge plug to a well transport and seating member. The well-bottom bridge plug and well-hole transport and the fixing member are passed down the hole through the small diameter tube and are positioned at a desired depth within the large diameter tube below the lower end of the tube. small diameter. A plurality of axially spaced elastomeric sealing members are moved to a radial overlap position to form an effective seal between the bridge plug body and the large diameter tubular, and anchor wedges in the downhole bridge plug are expanded to securely engage an inner wall of the large diameter tubular. The sealing members and anchoring wedges in the bridge plug can then be retracted to fall and / or move and eject the bridge plug into the well.
    [0005] US4765404 describes a packaging set for a whipstock in which the whipstock can be run in a pit liner up to a level above the bottom and milled through the liner wall without having to make a round trip with the column. well. The packaging set includes sliding anchors that initially secure the assembly and the packaging elements that fit tightly to the casing of the well to seal the casing while anchoring the device.
    [0006] Another state of the art document, US7708080, describes a shutter ("paker") that includes a sealing element, a meter and a plurality of collapsible rings. The rings are located between the meter and the sealing element.
    [0007] Document US4441552 discloses a hydraulic configuration tool for use with a plug having expandable anchor means for anchoring the plug in a well hole, a conduit to allow flow through the plug and a sliding valve positioned in the conduit having a lower open position and upper closed position. The inner and outer tubular portions are telescopically interconnected with the inner portion receiving a sliding mandrel. The tool conduit is connected to the inner sleeve with a shear stress collar, the mandrel passing through the collar and into the conduit for engagement with the valve. Annular pistons are provided between the inner and outer sleeves and between the mandrel and the inner sleeve. A check valve is hingedly attached to one side of the inner sleeve to seal the top of the mandrel. Pressurizing the inner sleeve via the pipe column from which the tool and plug are suspended pressurizes the annular spaces below the pistons, thus forcing the inner sleeve as well as the mandrel upwards to define the tool. Such upward movement of the inner sleeve breaks a seal at the lower end of the sleeve to allow depressurization of the annular space below the mandrel piston which forces the mandrel down. A locking ring locks the mandrel in its lower position to allow additional operation of the valve with the mandrel. BRIEF DESCRIPTION

    [00011] The following descriptions should not be considered in any way limiting. With reference to the accompanying drawings, similar elements are numbered in the same way:
    [00012] FIG. 1 represents a cross-sectional view of a packing element system in an unsealed condition;
    [00013] FIG. 2 represents a cross-sectional view of a packing element system in a sealed condition, and
    [00014] FIG. 3 represents a perspective and sectional view of a set of support rings, as disclosed herein. DETAILED DESCRIPTION
    [00015] A detailed description of one or more modalities of the method and apparatus disclosed, with reference to the Figures, is presented here by way of example and not limitation.
    [00016] Referring to Figures 1 and 2, a cross section is shown of a permanent or recoverable packing element system 10 that can be used as a seal, a plug, a cement retainer, or similar annular seal configuration , rock bottom. The packing element system 10 is shown in a retracted or disabled condition in FIG. 1 and in a condition defined in FIG. 2. The tubular of the packing element system 10 is illustrated in cross section, within another tubular structure 12, such as a coating segment. In the disabled state shown in FIG. 1, there is a gap 14 between the inner surface 16 of the tubular structure 12 and a first petal support 18. The gap 14 is made by the packing element 20, when the packing element system 10 is compressed, as shown in FIG. 2. In an exemplary embodiment, the packing element 20 is a deformable element, such as, but not limited to, a single piece composite element with vulcanized ends over a softer central element section to provide greater resistance to extrusion.
    [00017] Extrusion of element 20 is prevented by support rings, including an expandable outer support ring 22 and an expandable inner support ring 24. Rings 22 and 24 are expandable to occupy gap 14 to prevent element 20 to extrude, in the direction of the support rings 22 and 24. In the illustrated embodiment, a first area 30 of the element 20 is adjacent to a first set of support rings 26 and a second area 32 of the element 20 is adjacent to a second set of elements support rings 28, such that the element 20 cannot extrude in both axial directions, when the support rings 26, 28 are driven to be expanded, as shown in FIG. two.
    [00018] FIG. 3 illustrates a perspective view of the expandable inner support ring 24 and a sectional view of the expandable outer support ring 22 to show the expandable inner support ring 24 nested therein. The expandable inner support ring 24 includes a first set of grooves 36 extending from a first end 38 of the expandable inner support ring 24. A threaded hole or other key feature 40 is provided adjacent to a second end 42 of the expansion ring. expandable inner support 24. The hinge area 44 of the expandable inner support ring 24 is provided between the first and second ends 38, 42. The first set of grooves 36 divides the expandable inner support ring 24 into a plurality of first flanges 46 having an inner surface 48 and an outer surface 50. The first flanges 46 are foldable in the hinge area 44. The edges 52 of the first adjacent flanges 46 can be separated from each other at the first end 38 of the expandable inner bearing ring 24, by a first distance, in a first instance or condition not defined and by a second distance, in a second instance or condition defined, where the second di stance becomes increasingly larger than the first distance as the first flanges 46 widen outward. In an exemplary alternative embodiment, the first flanges 46 may not be separated in the indefinite condition, but instead they may contact or overlap each other, in a first instance or defined condition, and then may become less overlapping or separated in a second instance or defined condition. The flange area of the expandable inner support ring 24, from the hinge area 44 to the first end 38, has a substantially tapered cone shape that has a larger radial dimension at the first end 38 in the defined or expanded condition than in the condition undefined or retracted. The non-expandable part 74 of the expandable inner support ring 24 is provided between the hinge area 44 and the second end 42, and the non-expandable part 74 accommodates the switching feature 40.
    [00019] Furthermore, as shown in FIG. 3, the expandable outer support ring 22 includes a second set of grooves 54 that extends from a first end 56 of the expandable outer support ring 22. A threaded hole another key feature 58 is provided adjacent to a second end 60 of the ring expandable outer support ring 22 such that the expandable outer support ring 22 can be rotatably locked or keyed to the expandable inner support ring 24, such as via a thread 62. The pivot area 64 of the expandable outer support ring 22 it is provided between the first and second ends 56, 60. The second set of grooves 54 divides the expandable outer bearing ring 22 into a plurality of second flanges 66 having an inner surface 68 and outer surfaces 70, 72. The second flanges 66 they are foldable in the hinge area 64. The non-expandable part 76 of the expandable outer support ring 22 is provided between the hinge area 64 and the second end 60, and the non-expandable part level 76 accommodates switching feature 58. In an exemplary embodiment, the second flanges 66 of the expandable outer support ring 22 have a substantially triangular cross section, providing additional strength to the support ring 22. In other exemplary embodiments, the second flanges 66 they can be rounded or thickened to provide rigidity, although other cross sections of the second flanges 66 are also within the scope of these modalities. In a case where the second flanges 66 are provided with a substantially triangular cross section, the support ring 22 has a substantially cylindrical cross section along the outer surface 70 in an undefined state, and the outer surface 70 of the second flanges 66 is within a substantially constant distance from the inner surface 16 of the coating 12 during the undefined condition. In an exemplary embodiment, the substantially constant distance between the outer surface 70 and the inner surface 16 in the undefined condition is substantially the same as the gap 14, thus assisting the insertion and retraction of the system 10 within the coating 12. The edges 78 of the second adjacent flanges 66 can be separated from each other at the first end 56 of the expandable outer support ring 22 by a first distance in an undefined condition and a second distance in a defined condition, and the second distance becomes increasingly larger than the first while the second flanges 66 widen outwards. In an exemplary embodiment, the second distance is not greater than the width of the first flanges 46 in order to prevent the extrusion of the element 20 past the support rings 22 and 24. Likewise, the second distance between the edges 52 of the first adjacent flanges 46 in a defined condition is not greater than a width of the second flanges 66, in order to avoid extrusion of the element 20 past the support rings 22 and 24. In an alternative exemplary embodiment, the second flanges 66 may not be separated in the indefinite condition, but can instead contact each other, or overlap each other, in a first instance or indefinite condition, and then can become less overlapping or separated in a second instance or defined condition.
    [00020] The inner surfaces 68 of the second flanges 66 make contact with the outer surfaces 50 of the first flanges 46. In an exemplary embodiment where the first and second grooves 36, 54 separate the first and second flanges 46, 66, respectively, the second grooves 54 overlap the first flanges 46, and the first grooves 36 are overlapped by the second flanges 66 to ensure that there is no extrusion gap between the support rings 22 and 24 following expansion. The multiple first and second grooves 36, 54 allow for expansion with minimal force. The actual number and size of grooves 26, 54 and flanges 46, 66 on each of rings 22, 24 are variable, based on design requirements. The inner and outer support rings 24, 22 can be substantially the same for the first and second sets of support rings 26, 28. However, the inner and outer support rings 24, 22 of the first and second sets of support rings support 26, 28 may include modified switching features for engagement with respective adjacent structures.
    [00021] With reference again to Figures 1 and 2, in order to activate the support rings 22 and 24, a large number of other components of the system 10 are used including components bore above the system 10 in the direction bore above the rings of support 26, and downhole components of the system 10 in the downhole direction of the support rings 28. The petal support 18 includes a ramp surface 34, which interacts with the inner surface 48 of the expandable inner support ring 24 in the first set of support rings 26 during axial compression of the system 10 to cause the first set of support rings 26 to expand from a first radial dimension R1 shown in FIG. 1 to a second radial dimension R2 shown in FIG. 2, where R2 is greater than R1. The expansion of the support rings 22 and 24 crosses the entire gap4, in one modality, or at least a substantial part of the gap4, in other modalities. In an exemplary modality, R2 is substantially equal to R1 plus the distance defined by clearance 14.
    [00022] In FIG. 1, prior to the expansion of the support rings 22 and 24, the non-expandable part 74 of the inner support ring 24 is adjacent to a glove part 80 of the first petal support 18. In an exemplary embodiment, the glove part 80 of the first petal support 18 is fitted within the inner support ring 24 and rotatably locked to it by a rotational locking tab 82, although the inner support ring 24 is still axially movable with respect to the first petal support 18. A space 84 is formed between the inner surface 48 of the first flanges 46 of the inner support ring 24 and the first petal support 18. While the support rings 26 expand, the non-expandable parts 74, 76 of the support rings 26, slide in relative to the petal support 18, moving along the glove part 80, while the first flanges 46 of the inner support ring 24 make contact with the ramp surface and rise through the ramp 34 of the first petal support 18. The flanges 46, 66 of support rings 26 are able to expand past an external dimension of the first petal support 18 until the hinge area 44 contacts the ramp surface 34 and the space 84 is completely absorbed by the support rings 26 as shown in FIG. 2, with the first flanges 46 of the inner support ring 24 supported by the ramp surface 34 of the first petal support 18 and the second flanges 66 of the outer support ring 22 supported on the first flanges 46 of the inner support ring 24. In addition In addition, the angled surface 86 of the body 88 makes face-to-face contact with the outer surface 72 of the second flanges 66 of the expandable outer ring 22, such that the rings 22, 24 are supported by contact faces to resist the forces that are applied during the pressure test above and below the packing element 20.
    [00023] Likewise, the support rings 28 can slide in relation to a sleeve part 90 of the ramp body 92 on the opposite side of the element 20. The first flanges 46 of the inner support ring 24 rise up the ramp on the surface from the ramp 94 of the ramp body 92 until the space 96 is occupied by the support rings 28. The second flanges 66 of the expandable external support ring 22 touch and are supported by the angled surface 98 of the second petal support 100 to fully support the support rings 28. In an exemplary embodiment, it should be noted that the second petal support 100 for the support rings 28 is modified to accommodate support rings in the downward direction facing the support rings 28, which helps the system 10 with recoverability. In such an exemplary embodiment, the non-expandable part 76 of the outer support ring 22 is connected to a sleeve part 102 of the second petal support 100, such as by thread assembly 110, and the sleeve part 90 of the ramp body 92 moves axially with respect to the glove portion 102 of the second petal holder 100.
    [00024] In an exemplary embodiment, an anchor, such as a shutter having fillings 104 formed on it, raises the ramp up at an opposite end of the ramp body 92 to anchor the packing system to the liner 12. In one embodiment exemplary alternative, the support rings 28 can face in the direction of the hole above, in an opposite direction than the support rings 26, and employ a mirror image of the petal support 18 and angled surface 86 to ramp up and support support rings expanded 28. Such a modality may be applicable, but not limited to, an appropriate system for permanent type equipment.
    [00025] In an exemplary embodiment, the first petal support 18, the ramp body 92 and the support rings 26, 28 are clamped, respectively, together with shear screws 106, 108 that are sheared during the configuration stages .
    [00026] While system 10 may include features such as petal supports attached to the main body, so as to be suitable for permanent type equipment, which requires machining, and grafts that anchor the plug in the liner 12, system 10 also includes features that assist in the recoverability of the device, thus providing a recoverable tool. It is possible to retract support rings 22 and 24 a from R2 to R1 to provide clearance 14, as shown in FIG. 1.
    [00027] In addition, in an exemplary embodiment, both sets of support rings 26 and 28 are facing downwards to help recoverability. That is, the first ends of the support rings 26, 28 are, respectively, closer to the downhole end of the system 10, while the second ends of the support rings 26, 28 are, respectively, closer to the bore end. above system 10, and the first ends have a larger diameter than the second ends. The support rings 26, 28 face in the same direction so that both sets of support rings 26, 28 point towards the hole end above the tubular, to assist in the recovery of the system from the tubular. The activation and deactivation of system 10 is therefore possible for a plurality of cycles.
    [00028] Although the invention has been described with reference to an exemplary modality or modalities, it should be understood by those skilled in the art that various changes can be made and equivalents can be replaced by elements of these without departing from the scope of the invention. In addition, many modifications can be made to adapt a particular situation or material to the precepts of the invention without departing from its essential scope. Therefore, it is intended that the invention is not limited to the particular modality disclosed as the best method contemplated for carrying out this invention, but that the invention will include all modifications falling within the scope of the claims. Also, in the drawings and in the description, exemplary modalities of the invention have been disclosed, and although specific terms may have been used, unless otherwise stated, they are used only in a generic and descriptive sense and not for purposes of limitation, therefore , so the scope of the invention is not limited. Furthermore, the use of the terms, first second, etc., does not denote any order or importance, but instead, the terms, first, second, etc. are used to distinguish one element from the other. Furthermore, the use of the terms one, etc. they do not denote a quantity limitation, but instead, they denote the presence of at least one of the referenced item.
