Definitions
- Expanding tubular member carrying one or more inflatable seals carrying one or more inflatable seals
- the invention relates to the field of drilling, including oil drilling and geothermal.
- the invention relates to a device comprising a radially expandable tubular element which is intended to seal or plug a well or pipe and which comprises on its outer face one or more annular sealing modules.
- FIGs 1 and 2 To illustrate the state of the art in the art, there is shown in Figures 1 and 2 attached, a portion of metal tubular pipe BP, known in the English terminology of "casing", which is placed inside. a well A (it could however be a casing).
- a cylindrical jacket C of metal or radially expandable tubular element whose ends are fixed sealingly to the face on the outer surface of the pipe BP, for example via rings or rings B.
- An opening O is formed in the wall of the pipe BP (it may be provided several openings), so as to communicate the internal space of the BP pipe with the annular space formed between the wall of the BP pipe and the shirt vs.
- the jacket C is covered over all or part of its length with a layer of elastically deformable material, for example elastomer, which constitutes a "sheet", or “strip", annular sealing, a few millimeters thick.
- the liner may be covered with a plurality of sealing modules D, spaced apart from one another.
- the jacket C, and in particular the sealing modules D, are fixed against the internal face of the casing, at the level of the zone to be sealed, by radial expansion.
- This expansion operation is carried out, in the example illustrated, by hydroforming a fluid under pressure.
- one or more of the elastomer sealing modules D are located at / in front of a cavity F formed in the inner wall. of the well A. In this case, there is no longer any contact between the inner wall of the well A and the sealing module D, thus creating a communication space between the annular spaces EA1 and EA2 above. In other words, under these conditions, the seal is not satisfactory.
- the invention therefore particularly aims to overcome all or part of the disadvantages of the prior art.
- the object of the invention is, in at least one embodiment, to provide a radially expandable tubular element, especially by hydroforming, equipped on its outer face with one or more sealing modules that fully fulfill their function when they are applied to the wall of a casing or well.
- Another object of the invention in at least one embodiment, is to provide such an element:
- the invention manages to fill all or part of these objectives through a radially expandable metal tubular element, which has on its outer face at least one annular sealing module.
- said annular sealing module comprises at least one annular seal of an inflatable material, said inflatable seal, disposed between two annular abutments fixed on said outer face of said tubular element.
- the invention thus proposes a radially expandable tubular element, especially by hydroforming, equipped on its outer face with one or more sealing modules intended to be applied to the wall of a casing or well.
- Each sealing module consists of at least one annular seal (or sealing ring) of inflatable or self-inflating material, such as an inflatable elastomer (in English "swelling elastomer") which swells on contact a fluid present in the well (water, mud or oil in particular).
- inflatable or self-inflating material such as an inflatable elastomer (in English "swelling elastomer") which swells on contact a fluid present in the well (water, mud or oil in particular).
- Such a seal is able to widen axially (within the limit established by the stops which are fixed on the expandable tubular element) and radially to come into contact with the wall of a casing or well, and to seal the seal. annular space between the tubular element and the wall.
- such a seal is able to withstand mechanically, thermally and chemically attacks and the various constraints related to the application, while ensuring a perfect seal when applied with force against a casing or formation.
- NBR nitrile rubber
- HNBR hydrogenated nitrile
- FKM fluoroelastomers
- said tubular element further comprises two anti-extrusion rings each disposed between one of said annular abutments and said at least one inflatable seal.
- These anti-extrusion rings eliminate, or at least limit, the extrusion of the inflatable seal when the latter is pressed against the inner wall of a cavity or a casing. The rings maintain, therefore, an optimal seal.
- each anti-extrusion ring is in two parts and comprises two beveled surfaces formed respectively on each of said parts, said beveled surfaces being located facing one another and being able to slide one relative to each other by axial movement (along the longitudinal axis of the tubular member) of said inflatable seal so as to cause radial displacement (perpendicular to the longitudinal axis of the tubular element) of one of said two parts.
- each anti-extrusion ring is made of polytetrafluoroethylene (PTFE) or polyetheretherketone (PEEK).
- PTFE polytetrafluoroethylene
- PEEK polyetheretherketone
- said seal of inflatable material is sandwiched between two seals of non-inflatable material, said non-inflatable seals.
- each seal of non-inflatable material is in two parts, said first and second parts, of different hardness.
- the part having the least hardness, said first portion is juxtaposed to said seal of inflatable material.
- the first part has a hardness of between 75 and 80 shore A.
- the second part has a hardness of between 85 and 90 shore A.
- the first and second parts are manufactured separately and are placed in contact on said tubular element.
- the first and second parts are glued.
- the first and second parts are formed in one piece (in other words, they are vulcanized together).
- said inflatable material seal and the non-inflatable material seals are manufactured separately and are placed in contact on said tubular member.
- said seal of inflatable material and non-inflatable material seals are manufactured separately and are glued.
- said inflatable material seal and the non-inflatable material seals are integrally formed (in other words, they are vulcanized together).
- said annular stops are made of metal.
- an assembly of elements is proposed in association with the inflatable seal element to prevent the axial extrusion of the inflatable material (elastomer for example) and thus ensure a particularly effective seal.
- the seal module may comprise a stack of three or more layers of inflatable and non-inflatable elastomer. Thus, a seal of inflatable material may be placed coaxially sandwiched between two seals non-inflatable material.
- the sealing module may consist of an annular seal of inflatable material placed between a first anti-extrusion ring and a second anti-extrusion ring.
- the seal or seal (s) is / are connected (s) to said tubular element by a sliding pivot connection.
- the inflatable seal is thus able to move axially on the expandable tubular element.
- said inflatable seal is able to pass from a retracted mode in which it presents a first volume to an expanded mode in which it has a second volume greater than the first volume, said seal inflatable having a thickness less than or equal to the distance separating the two annular stops in the retracted mode.
- Such an inflatable seal can thus pass from an uninflated mode in which it has a first volume to an expanded mode in which it has a second volume greater than the first volume and in which it seals the annular space between the element expandable tubular and the wall of a well or casing.
- said tubular element is radially expandable by hydroforming.
- FIGS. 1 and 2 are schematic views, in a longitudinal sectional plane, of an isolation device according to the state of the art, respectively in the original state and once deformed radially;
- FIGS. 4A to 4C are diagrammatic longitudinal sectional views of an isolation device of a portion of a wellbore according to a first embodiment of the invention
- FIGS. 5A to 5D show a second embodiment of the device of the invention
- FIG. 6 represents a third embodiment of the device of the invention.
- FIGS. 7A to 7C show a fourth embodiment of the device of the invention.
- FIGS. 8A to 8D represent a fifth embodiment of the device of the invention.
- the metal tubular element 1 is radially expandable by hydroforming. Although this is not illustrated, the tubular element 1 is sealingly attached at its ends to the outer face of a pipe, by means of rings or rings. At least one opening is formed in the wall of the pipe, so as to communicate its internal space with the space between the outer wall of the pipe and the tubular element 1.
- the annular sealing module here comprises two annular metal stops 21 between which is inserted an annular seal 22 which is advantageously made of an inflatable elastomeric material.
- the two annular metal stops 21 are fixed on the outer face of the tubular metal element 1, for example by welding.
- the seal 22 is not fixed on the tubular element 1 and is thus free to pivot about the tubular element 1 and to move axially (along the longitudinal axis of the tubular element 1).
- the tubular metal element 1 and the annular metal stops 21 are, for example, made of steel, and are able to deform plastically.
- the annular seal 22 has in cross section a substantially rectangular shape, two opposite corners facing the inner wall of the well A being beveled.
- Each of the annular metal stops 21 has in cross section a substantially triangular shape.
- FIG. 4A shows the expanded metal tubular element 1 radially beyond its limit of elastic deformation.
- Figure 4B shows, in the expanded position of the tubular element 1 metal, the seal 22 in its inflated state, the upper surface of the seal 22 being curved.
- the latter inflated in contact with the fluid (water, oil) present in the well A, and filled the space of the cavity F.
- the seal 22 is in contact with the annular metal stops 21.
- the seal 22 expands radially outward (that is to say towards the inner wall of the well A) and axially towards the annular metal stops 21.
- the seal 22 is sealingly applied against the inner wall of the well A.
- the annular space EA1 is thus isolated in fluid communication and in pressure of the annular space EA2.
- the seal 22 is subjected to a differential pressure. So that the differential pressure does not cause irreversible extrusion and degradation of the seal 22 (and thus the seal between the annular spaces EA1 and EA2), the annular metal stops 21 are configured to maintain axially the seal in sealing position.
- FIG. 4C it can be seen that the application of a differential pressure (illustrated by the arrows on the right) between the annular spaces EA1 and EA2 has the effect of moving the seal 22 axially towards the stop 21 located to the left.
- the seal 22 thus behaves dynamically.
- a second embodiment of the invention is described.
- This embodiment differs only from the previous embodiment by the implementation of a non-inflatable seal 24 (elastomer for example) on either side of the inflatable seal 22.
- the non-inflatable seals 24 do not lose their mechanical characteristics in contact with the fluid and over time, and thus prevent the extrusion of the inflatable seal 22.
- the non-inflatable seals 24 serve as an anti-extrusion barrier of the inflatable seal 22.
- FIG. 5A shows the tubular element 1 when it is not yet deformed before it is put into place in the well A.
- the seals 22, 24 are mounted around the tubular element 1 without being fixed on it latest. They are spaced from the stops 21.
- the seal 22 of inflatable material and the seals 24 of non-inflatable material are manufactured separately and are placed in contact on said tubular element.
- the seal 22 of inflatable material and the seals 24 non-inflatable material are manufactured separately and are glued.
- the seal 22 of inflatable material and the seals 24 of non-inflatable material are formed in one piece (in other words, they are vulcanized together).
- FIG. 5B shows the expanded metal tubular element 1 in the well A.
- FIG. 5C shows, in the expanded position of the metal tubular element 1, the seal 22 in its expanded state.
- the latter has swollen in contact with the fluid (water, oil) present in the well A, and filled the space of the cavity F.
- the seals 24 have moved axially under the effect of the swelling of the seal 22, and come to bear against the stops 21, thus preventing the inflatable seal 22 from extruding thereby reducing the effectiveness of the seal 22.
- FIG. 5D it can be seen that the application of a differential pressure (illustrated by the arrows on the right) between the annular spaces EA1 and EA2 has the effect of pressing / compressing the seal 22 in the axial direction against the stop 21 on the left, the anti-extrusion barrier being formed by the non-inflatable seal 24 located to the left of the seal 22.
- a differential pressure illustrated by the arrows on the right
- This figure 6 shows the tubular element 1 when it is not yet deformed and installed in a well or casing.
- two non-inflatable seals 24 are disposed on either side of the inflatable seal 22.
- Each non-inflatable seal 24 is composed of two parts 24A, 24B made of different elastomers and having different properties.
- the elastomer of the portion 24B has a hardness of between 85 and 90 Shore A in this example, and the elastomer of the portion 24A has a hardness of between 75 and 80 shore A. It is noted that a greater hardness gives a better resistance to extrusion.
- the two parts 24A, 24B can be independent, and are, for example, manufactured separately and juxtaposed to the assembly (they are left free or glued).
- the two parts 24A, 24B are integral, the two constituent elastomers being vulcanized together and forming one and the same bi-gum element.
- the non-inflatable seal 24 may be composed of more than two parts 24A, 24B manufactured in different elastomers and having different properties.
- FIGS. 7A to 7C A fourth embodiment of the invention is described with reference to FIGS. 7A to 7C.
- the inflatable seal 22 is placed between two anti-extrusion rings 26, each of the anti-extrusion rings 26 being placed between the seal 22 and an annular metal stop 21, in contact with this last.
- the anti-extrusion rings 26 are movably mounted on the tubular element 1.
- Each anti-extrusion ring 26 comprises two parts 26A, 26B in the shape of a right triangle. These two parts 26A, 26B are arranged head to tail, so that their inclined surfaces (corresponding to the base of the triangle) are facing each other.
- the anti-extrusion rings 26 are, for example, made of polytetrafluoroethylene (PTFE) or polyetheretherketone (PEEK).
- PTFE polytetrafluoroethylene
- PEEK polyetheretherketone
- Figure 7A shows the expanded metal tubular element 1.
- Figure 7B shows, in the expanded position of the tubular element 1 metal, the seal 22 inflated. The latter has filled the cavity F and is in contact with the anti-extrusion rings 26
- FIG. 7C it can be seen that the application of a differential pressure (illustrated by the arrows on the right) between the annular spaces EA1 and EA2 has the effect of pressing / compressing the seal 22 in the axial direction against the anti-extrusion ring 26 located on the left. More specifically, the pressure applied in the annular space EA2 passes between the stop 21 on the right and the inner wall of the well A, then between the anti-extrusion ring 26 on the right and the inner wall of the well A. This has the effect to press the seal 22 against the portion 26B of the ring 26 to the left of Figure 7C.
- a differential pressure illustrated by the arrows on the right
- the portion 26B of the ring 26, and its bevelled surface, slides toward the stop 21 on the left, and by "wedge" effect is raised and cause the radial displacement outwards (towards the wall of the well A). of the portion 26A of the ring 26 until the portion 26A is against the wall.
- the portions 26A, 26B of the left-hand ring 26 thus cooperate perfectly with the inflatable seal 22 so as to avoid the extrusion thereof and to ensure dynamic sealing between the tubular element 1 and the inner wall well A.
- a fifth embodiment of the invention is described with reference to FIGS. 8A to 8D.
- This variant differs only from the previous embodiment by the implementation of a non-inflatable seal 24 (elastomer for example) on either side of the inflatable seal 22.
- FIG. 8A shows the tubular element 1 when it is not yet deformed and installed in a well or casing.
- the inflatable seal 22 is placed between two anti-extrusion rings 26, each of the anti-extrusion rings 26 being placed between the seal 22 and an annular metal stop 21.
- non-inflatable seals 24 are disposed on either side of the inflatable seal 22.
- Figure 8B shows the expanded tubular member 1.
- FIG. 8C shows, in the expanded position of the tubular element 1, the swollen seal 22.
- FIG. 8D it can be seen that the application of a differential pressure (illustrated by the arrows on the right) between the annular spaces EA1 and EA2 has the effect of pressing / compressing the seal 22 and the seal 24 non-inflatable located left in the axial direction against the anti-extrusion ring 26 to the left.
- the portions 26A, 26B of the left ring 26 and the non-inflatable seal 24 located on the left perfectly cooperate with the inflatable seal 22 so as to avoid the extrusion thereof and to ensure the dynamic sealing between the tubular element 1 and the inner wall of the well A. It should be noted that other forms than those illustrated are possible for stops, seals and anti-extrusion rings.
- anti-extrusion rings 26 with the seal 22, 24 as described in relation with FIG. 6.
