Definitions

  • the present invention relates to an annular barrier for mounting as part of a well tubular structure, the annular barrier being adapted to be expanded in an annulus between the well tubular structure and an inside wall of a borehole.
  • annular barriers or packers are often used to seal off a section of the borehole, such as an oil producing zone in the formation.
  • the section may be sealed off to avoid excessive amounts of water flowing into the production casing from other parts of the well.
  • Known annular barriers often comprise a tubular part extending in a longitudinal direction, such as a casing surrounded by an expandable sleeve.
  • the expandable sleeve is expanded in an annulus between the casing and an inside wall of a borehole.
  • the expandable sleeve is often arranged substantially concentrically in relation to the tubular part, and a centre axis of the expandable sleeve coincides with a centre axis of the tubular part. The centre axis of the expandable sleeve thus extends inside the tubular part.
  • the diameter may vary substantially along the extension of the borehole due to changes in the composition of the formation.
  • the walls of the borehole may for example partly collapse during or after drilling, or fluid flowing in the well may erode the walls.
  • annular barriers may be expanded to have an outer diameter of maximum 20-30% beyond the outer diameter of the casing. This may be adequate in some parts of the well, however, in sections having an increased diameter, it may not to sufficient to provide a proper seal between the casing and the wall of the borehole.
  • annular barrier for mounting as part of a well tubular structure, the annular barrier being adapted to be expanded in an annulus between the well tubular structure and an inside wall of a borehole, and the annular barrier comprising:
  • annular barrier may be sufficiently expanded for sealing a larger annulus than annular barriers of the prior art.
  • a centre axis of the expandable tube may be arranged outside the tubular part.
  • centre axis of the expandable tube may coil around the tubular part in the longitudinal direction.
  • the expandable tube may coil around the tubular part in the longitudinal direction
  • an inner space of the expandable tube may be in fluid communication with an inner passage of the tubular part.
  • a cross-section of the expandable tube in a relaxed position may be substantially oval-shaped.
  • a shape of a cross-section of the expandable tube in a relaxed position may comprise multiple creases.
  • a cross-section of the expandable tube in an expanded position may be substantially circular.
  • the annular barrier may comprise a plurality of expandable tubes extending on the outside of the tubular part in the longitudinal direction.
  • the annular barrier according to the invention may further comprise a sealing element provided on an outer surface of the one or more expandable tube(s) for providing sealing against the inside wall of the borehole.
  • the sealing element may be an expandable sleeve extending on the outside of the one or more expandable tube(s).
  • the sealing element may be made of metal, polymer, elastomer, rubber or a swellable material.
  • the one or more expandable tube(s) may at least partly be embedded in a sealing material.
  • the annular barrier may further comprise one or more sealing bands encircling the sealing element or the expandable sleeve to provide additional sealing.
  • the annular barrier may comprise a connecting part arranged on the outside of the tubular part for attaching the one or more expandable tube(s) to the tubular part.
  • connection part may attach one end of each of the one or more expandable tube(s) to the tubular part.
  • the annular barrier may comprise a second connection part for attaching the opposite end of each of the one or more expandable tube(s) to the tubular part.
  • the annular barrier may comprise a fixed connection part and a sliding connection part for attaching opposite ends of the one or more expandable tube(s).
  • connection part may comprise one or more fluid channel(s) for providing fluid communication between the inner space of the one or more expandable tube(s) and the inner passage of the tubular part.
  • an outer diameter of the annular barrier in an expanded position may be up to 150% of an outer diameter of the tubular part.
  • an outer diameter of the annular barrier in an expanded position may be 140% to 150% of an outer diameter of the tubular part.
  • the annular barrier may be able to provide sufficient sealing in wellbores having a greatly varying inner diameter.
  • the present invention furthermore relates to a method of expanding an annular barrier as described above in an annulus between a well tubular structure and an inside wall of a borehole, the method comprising the step of:
  • the fluid may be injected into the inner space by pressurising an inner passage of the tubular part, and a fluid is thereby injected into the well tubular structure, providing fluid communication between the inner passage of the tubular structure and the inner space of the expandable tube(s).
  • the invention relates to a downhole system comprising
  • Fig. 1a and 1b show an annular barrier 1 for being mounted as part of a well tubular structure 3 in a downhole system 100, as shown in Fig. 8 .
  • the annular barrier 1 comprises a tubular part 6 extending in a longitudinal direction and a plurality of expandable tubes 7 extending outside the tubular part 6, also shown in Figs. 2a and 2b .
  • the expandable tubes 7 are arranged around the periphery of the tubular part 6, and a centre axis 72 of each of the expandable tubes thus extends outside the tubular part 6 in the longitudinal direction of the annular barrier 1.
  • connection part 9 comprises fluid channels 91 for providing fluid communication between an inner space 73 of each of the expandable tubes and an inner passage 31 of the tubular part 6.
  • the fluid channel 91 extends between an aperture 61 in the tubular part 6 and an inlet 74 provided in one end of each of the expandable tubes 7.
  • the annular barrier 1 further comprises a sealing element 8 provided on an outer surface 71 of the plurality of expandable tubes 7.
  • the sealing element 8 is an expandable sleeve 81, at least one end of which engages in a sealing relationship with the tubular part 6.
  • the expandable sleeve 81 is adapted to provide a sealing barrier between the tubular part 6 and the inside wall 41 of the borehole 4, since the expandable tubes 7, when expanded, force the expandable sleeve towards the inside wall of the borehole 4.
  • the expandable sleeve 81 is attached to the connection part 9, however, it may also be attached directly to the tubular part 6 or to the expandable tubes 7.
  • the sealing element 8 and/or the expandable sleeve 81 may be made of metal, polymer, elastomer, rubber, a swellable material, etc.
  • Having a sealing element made of a swellable material may further increase the sealing effect of the sealing element or the expandable sleeve 81 as the material may be designed to swell when it comes into contact with specific types of fluid, such as water or other well fluids present in the borehole, an injected liquid or gas, etc.
  • the annular barrier 1 may comprise additional sealing bands 82 provided outside the sealing element 8 or expandable sleeve 81 for providing additional sealing against the inside wall 41 of the borehole 4.
  • Fig. 1a the expandable tube 7 is shown in a relaxed position
  • Fig. 1b shows the same expandable tube in an expanded position
  • fluid is injected into the inner space 73 of the tube via the fluid channel 91 in the connection part 9 from the inner passage 31 of the tubular part 6 fluidly connected to a well tubular structure 3, as shown in Fig. 8 .
  • the fluid is pressurised from the top of the well, and the well tubular structure 3 is thereby pressurised to be able to expand the expandable tubes 7.
  • the expandable tube 7 increases the outer diameter D1e of the annular barrier 1.
  • Figs. 2a and 2b are cross-sectional views of the annular barrier shown in Fig. 1a and 1b , respectively.
  • the annular barrier 1 is shown in a relaxed position before expansion.
  • the expandable tubes 7 are attached to and kept in place along the axial extension of the annular barrier 1 by the connection part 8, and the inlet 74 shown in one end of each of the expandable tubes 7 is connected with fluid channels in the connection part.
  • cross-sections of the expandable tubes 7 in the relaxed position are substantially oval-shaped.
  • the cross-sections of the expandable tubes are transformed from the substantially oval shape to a substantially circular shape.
  • the outer diameter D1 of the annular barrier 1 is significantly increased, and the expandable sleeve 81 is forced outwards, as shown in Fig. 2b .
  • the outer diameter D1 of the annular barrier 1 may be increased from a smaller diameter to a larger diameter. This is done by expanding the tubes 7 by means of fluid and thereby changing the shape of the cross-section of the expandable tubes 7 and/or by stretching the material of the expandable tubes.
  • the expandable tubes 7 may have a cross-sectional shape in a relaxed position and comprise multiple creases. By pressurising the expandable tubes 7, the creases are smoothened, and the outer effective diameter of the expandable tubes may be increased.
  • Fig. 2d a cross-sectional view of another configuration of an annular barrier is shown.
  • the expandable tubes 7 are at least partially embedded in the sealing element 8.
  • the sealing element 8 expands as the expandable tubes are expanded, thereby increasing the outer diameter of the sealing element.
  • the sealing element is thus moved outwards from the tubular part during expansion.
  • the expandable tubes 7 are fully embedded in the sealing material 8.
  • the sealing material 8 may merely surround the expandable tubes 7 and not be arranged between the expandable tubes and the tubular part 6.
  • the unexpanded expandable tubes 7 When seen in cross-section, the unexpanded expandable tubes 7 are arranged side by side abutting each other, causing the wall of one expandable tube to be in contact with the wall of the adjacent expandable tube. When the expandable tubes 7 are expanded, a distance between the tubes is created, and this distance is the shortest if the unexpanded tubes abut each other in the unexpanded condition of the annular barrier 1.
  • FIG. 3a and 3b Another configuration of an annular barrier according to an embodiment of the invention is shown in Figs. 3a and 3b .
  • This annular barrier 1 comprises a tubular part 6 extending in a longitudinal direction and an expandable tube 7 extending outside the tubular part 6.
  • the expandable tube 7 is coiled around the tubular part 6 in the longitudinal direction.
  • the expandable tube 7 is attached to the tubular part 6 via a connection part 9 comprising a fluid channel 91 for providing fluid communication between an inner space 73 of the expandable tube and the inner passage 31 via an aperture 61 in the tubular part.
  • An opposite end of the expandable tube (not shown in Fig.
  • connection part 3a and 3b may also be attached to a connection part arranged on the outside of the tubular part 3, similar to the connection part shown in Fig. 3a, 3b and 3c , with the exception of the fluid channel which is only required in one of the connection parts.
  • the annular barrier may comprise multiple parallelly extending expandable tubes coiled around the tubular part.
  • both connection parts may have fluid channels connected with the inner space 73 of the tube.
  • Figs. 3a and 3b the expandable tube 7 is shown in a relaxed position, whereas Figs. 4a and 4b show the same expandable tube in an expanded position.
  • the expandable tube 7 is expanded by injecting a fluid into the inner space 73 via the fluid channel 91 in the connection part 9.
  • the cross-sections of the expandable tubes 7 are transformed from a substantially oval shape to a substantially circular shape, whereby the outer diameter D1 of the annular barrier is significantly increased.
  • expansion of the expandable tube 7 may cause changes in the mutual angle of windings and/or numbers of windings of the coiled expandable tube.
  • the expansion of the expandable tube 7 has the effect that the outer unexpanded diameter D1 u shown in Fig. 3b is increased to an outer expanded diameter D1 e , as shown in Fig. 4b .
  • the extension of the expandable tube 1 in the longitudinal direction is affected if the length of the expandable tube is to be kept constant.
  • One end of the expandable tube 7 may therefore be attached to a sliding connection part (not shown).
  • the expandable tube 7 may be attached to the tubular part 6 in only one end, as shown in Fig. 3a .
  • the expandable tube 7 may also be attached to fixed points along the tubular part 6 in both ends. However, this requires the material of the expandable tube to be able to withstand some stretching or thinning in the longitudinal direction of the expandable tube.
  • the annular barrier 1 of Fig. 3a further comprises a sealing element 8 provided on an outer surface 71 of the plurality of expandable tubes 7, as shown in Fig. 5a .
  • the sealing element 8 extends along the length of the expandable tube 8 and is provided on the outermost part of the outer surface 71 of the expandable tube 7, potentially facing the inside wall 41 of the borehole 4.
  • the sealing element 8 may be provided around part of or on the entire outer surface 71 of the expandable tube 7 in part of or the entire length of the expandable tube 7.
  • the sealing element 8 may also be constructed as an expandable sleeve 81, at least one of which end engages in a sealing relationship with the tubular part 6, as shown in Figs.
  • the annular barrier 1 may comprise additional sealing bands 82 provided outside the expandable sleeve 81.
  • the sealing element 8 or expandable sleeve 81 is adapted to provide a sealing barrier between the tubular part 6 and the inside wall 41 of the borehole 4 as the expandable tubes 7 are expanded and thereby force the sealing element 8 or expandable sleeve 81 towards the inside wall 41 of the borehole 4.
  • the expandable sleeve 81 may be attached to the connection part 9, directly to the tubular part 6 or to the expandable tubes 7.
  • Figs. 7a and 7b show yet another configuration of the annular barrier 1 where the expandable tube 7 is at least partially embedded in the sealing element 8.
  • the sealing element 8 expands as the expandable tubes are expanded, thereby increasing the outer diameter of the sealing element, and the sealing element is moved outwards away from the tubular part during expansion.
  • the outer diameter D1e of the annular barrier in an expanded position is up to 150% of an outer diameter D2 of the tubular part, also shown in Fig. 4b for exemplary purposes.
  • the outer diameter D1e of the annular barrier 1 may be expanded to have an outer diameter of 140% to 150% of the outer diameter D2 of the tubular part 6.
  • the annular barrier 1 may be able to provide sufficient sealing in wellbores having a greatly varying inner diameter.
  • Fig. 8 shows a downhole system 100 comprising a plurality of annular barriers 1.
  • the downhole system 100 is shown as comprising annular barriers 1 of different configurations.

  • an upper section of a well tubular structure 3 is provided, and another annular barrier 103 provides a sealing relationship between the intermediate casing 101 and the well tubular structure 3.
  • the well tubular structure 3 extends from the intermediate casing 101 down into the well.
  • the downhole system 100 further comprises a plurality of valve sections 105 for letting hydrocarbon-containing fluid into an inner space 31 of the well tubular structure 3.
  • the valve section 105 may contains inflow control valves 106 and/or a fracturing valve 107. Further, a screen 108 may be arranged opposite the valves.
  • the well tubular structure 3 may be a production casing or injection casing and/or comprise a multitude of other functional elements, such as sliding sleeves, screens, gravel packs, etc.
