DETAILED DESCRIPTION
[0011] Shown in FIG. 1 a portion of a string 10. The string 10 is a length of tubing installed in a downhole environment for various purposes such as drilling, injection and/or production. In some embodiments, the string 10 includes a plurality of centralizers 12 which extend outwardly from an outer surface 14 of the string 10 to prevent damage to the string 10 when the string 10 is run into or removed from the downhole environment. The plurality of centralizers 12 are disposed along a length of the string 10 and also around a perimeter of the string 10. The plurality of centralizers 12 may be secured to the string 10 by any conventional means, including welding and/or one or more mechanical fasteners such as bolts, or may be formed integral to the string 10. While the embodiment shown in FIG. 1 includes a plurality of centralizers 12, it is to be appreciated that in some embodiments, centralizers 12 may be absent from the string 10.
[0012] To monitor and/or control one or more devices downhole, one or more monitoring or control lines 16 extend along the outer surface 14 of the string 10. The lines may be, for example, electrical lines, hydraulic lines, and/or fiber optic lines, or the like. Further, while four lines 16 are shown in FIG. 1, it is to be appreciated that other quantities of lines 16, for example one, two, or ten lines 16 are contemplated herein. As shown in FIG. 2, at least one cover 18 is utilized to protect the one or more lines 16 from damage via, for example, impact while installing the string 10 in a hole. As shown, the cover 18 may be curved in a circumferential direction but it is to be understood that a cover without curvature is also contemplated. The cover 18 may extend substantially the length of a joint of the string 10. In some embodiments, perhaps because of the length of cover 18 necessary to protect the lines 16, it may be desired to utilize a quantity of covers 18 arranged axially along the string 10 instead of a single continuous cover 18. In some embodiments, the covers 18 may substantially abut, while in other embodiments, the covers 18 may have a gap between the covers to facilitate removal or opening of the covers 18. In one embodiment, each cover 18 will extend about 10 feet. The cover 18 may be affixed to one or more supports 20 extending outwardly from the outer surface 14. The supports 20 may be affixed to the outer surface 14 by welding or by other means including, for example, bolts.
[0013] As shown in FIG. 1, the supports 20 may be arranged so the lines 16 are located between two supports 20. The supports 20 are tall enough so that when the cover 18 is in a closed position as shown in FIG. 2, a protected space 22 between the cover 18 and the outer surface 14 of the string 10 is of sufficient dimensions for the lines 16 to be received therein and protected. In some embodiments, the cover 18 is located circumferentially between two centralizers 12. The cover 18 may be attached to the one or more supports 20 via a hinge 24 at a hinge side 26 of the cover 18. The hinge 24 allows the cover 18 to be opened and closed while remaining attached to the string 10. To ensure the cover 18 remains closed when desired, a non-hinge side 28 of the cover 18 includes a securement configuration to secure the cover 18 in a closed position. The securement configuration may be, for example, a fastener 30 (threaded, rivet, etc) extending through a cover hole 32 in the cover 18 into the support 20. Further, the securement configuration may be a clip, pin, magnet, or other suitable closure means. In one embodiment, as shown in FIG. 3, the cover 18 includes a retaining hook 34 which may be a substantially U-shaped bend in the non-hinge side 28 of the cover 18. The retaining hook 34 is configured to engage with a detent 36 which is, for example, formed into the support 20 disposed at the non-hinge side 28. When the cover 18 is moved from an open position towards a closed position, the retaining hook 34 slides along a ramp portion 38 of the support 20 until engaging the detent 36. While the detent 36 is illustrated with flat surfaces and sharp angles, a more rounded cross section is also contemplated.
[0014] In some embodiments, the cover 18 is secured to the supports 20 without a hinge 24, and has screws 30, retaining hooks 34 or other mechanisms to secure the cover 18 to the supports 20. For example, as shown in FIG. 4, the cover 18 includes retaining hooks 34 at each circumferential end of the cover 18, which engage to detents 36 on each support 20. In this embodiment, the cover 18 is installed by, for example, urging the cover 18 in a radially inward direction to engage the retaining hooks 34 to the detents 36.
[0015] In some embodiments, it is desirable to have lines 16 installed along the length of the string 10, across couplings of adjacent joints of the string 10. Referring to FIG. 5, a cross -coupling clamp 40 may be disposed at the coupling of two joints of string 10. The cross -coupling clamp 40 axially overlaps each joint of string 10 and circumferentially surrounds the string 10. The cross-coupling clamp 40 includes a collar 42 disposed at each end and a sleeve 44 extending axially between the two collars 42 across a coupling between the joints of the string 10. Referring to FIG. 6, each collar 42 includes at least one coupling hinge 46 and two coupling arms 48 extending from the coupling hinge 46. Each coupling arm 48 may include at least one coupling spacer 50 that, when the collar 42 is closed around the string 10 defines a coupling protected space 52 between the outer surface 14 and the coupling arm 48. The size of coupling spacer 50 used determines a height of the coupling protected space 52, and different sized coupling spacers 50 may be utilized depending on a size of lines 16 and/or desired height of the coupling protected space 52. In some embodiments, the coupling protected space 52 height is greater than a thickness of lines 16 that are disposed in the coupling protected space 52. This provides a coupling protected space 52 that extends around the circumference of the string 10 and allows for a helical arrangement of the lines 16 in the coupling protected space 52 to, for example, compensate for any variation in circumferential alignment of adjacent string joints 10 at the coupling. Referring again to FIG. 5, each coupling arm 48 includes a plurality of coupling fingers 54 configured to interlock with coupling fingers 54 of the other coupling arm 48 when the collar 42 is closed around the string 10. With the coupling fingers 54 interlocked, the cross-coupling clamp 40 is secured in the closed position by, for example, a coupling pin (not shown) installed through a plurality of coupling finger holes (not shown) in the plurality of coupling fingers 54 to prevent the cross -coupling clamp 40 from opening unexpectedly.
[0016] Referring again to FIG. 2, in some embodiments, the string 10 includes a screen 56 at the outer surface 14 to filter flow entering the string 10 for undesired materials. In some embodiments, the outer surface 14 may be a flow through tubular 58 having at least one line 16 attached thereto. The line 16 attached to the flow through tubular 58 may be a control line or monitoring line that is, for example, an electric line, hydraulic line, fiber optic line or the like.
[0017] While one or more embodiments have been shown and described, modifications and substitutions may be made thereto without departing from the spirit and scope of the invention. Accordingly, it is to be understood that the present invention has been described by way of illustrations and not limitation.
