Definitions

  • control lines have long been an important component of successful operations downhole. These may be hydraulic, electrical, fiber, etc. Control lines are needed to communicate with devices positioned downhole and therefore remote from a surface location at which personnel may be stationed.
  • TEC tubing encapsulated conductors
  • a flat pack is matrix of material, usually a polymer, into which is embedded a control line and cables for crush resistance.
  • the control line is completely encapsulated which is beneficial but the concept suffers in application due to the need at certain downhole tools to strip off the flat pack in order to pass the control line through the device.
  • a packer is one such device.
  • the result of a pass through is an exposed control line for a length which may be quite extended.
  • the exposed length of control line is subject to all stress factors. This has been avoided by using many splices in the line (i.e., no real feed-throughs, just breaks and splices at devices). There has been, however, no practical solution to the problem.
  • a control line protector including a matrix having at least one bumper and at least one receptacle.
  • a method for protecting a bare control line by positioning a protector having a matrix at least one bumper and at least one receptacle configured to accept the control line.
  • Figure 1 is a cross-sectional representation of a first embodiment of a retrofit protector
  • Figure 2 is a cross-sectional representation of a second embodiment of a retrofit protector
  • Figure 3 A is a cross-sectional representation of a third embodiment of a retrofit protector
  • Figure 3B is an elevation view of the protector of Figure 3 A;
  • Figures 3C-3F are alternate elevation view like 3B but with distinct constructions of the protector;
  • Figure 4 is a cross-sectional representation of a fourth embodiment of a retrofit protector.
  • Figure 5 is a cross-sectional representation of a fifth embodiment of a retrofit protector.
  • the protector 10 comprises a matrix 12, at least one bumper 14 and at least one receptacle 16.
  • the matrix comprises a material capable of being formed to a configuration substantially as shown and holding that shape.
  • the matrix comprises a material that is resistant to vibration, abrasion, erosion, chemicals and mechanical compression or tension.
  • the material is polymeric.
  • Bumper(s) 14 comprise any relatively strong material having both tensile and compression resistant characteristics such as steel cable. Since flexibility is also desirable, stranded cable may be indicated for some embodiments.
  • the matrix and bumpers are similar but the receptacle 16 is distinct.
  • receptacle 16a is configured to extend into a control area 20 of matrix 12 from one side 22 of protector 10.
  • receptacle opening 24 is of a dimension smaller than a control line (not shown) to be housed in receptacle 16a to a degree calculated to provide retention of the control line in receptacle 16a while taking into account deformability of matrix 12 such that a control line is "snappable" into receptacle 16a by hand or by suitable equipment, depending upon application.
  • a control line is "snappable" into receptacle 16a by hand or by suitable equipment, depending upon application.
  • one embodiment employees a receptacle bore 26 of about 6 1/2 millimeters whereas the receptacle opening 24a is about 4 millimeters wide.
  • receptacle 16a is offset from a centerline of the protector 10 in the longer direction depicted. This position reduces insertion force of the control line and increases protection of the control line by enhancing crush resistance particularly from crushing against a casing or open bore wall of a wellbore in which the protector is run.
  • receptacle opening 24b is provided with an angle to ease installation of a control line.
  • the angle is of about 5° to about 25° and reduces the force required to insert the control line into receptacle 16b, while still requiring passage through a smaller dimension area calculated to retain the control line.
  • this system may be helpful in that it will tend to be more gentle on the control line.
  • a third embodiment is illustrated in Figure 3. This embodiment provides closure of the receptacle opening discussed in the previous embodiments.
  • the embodiment of Figure 3 includes a living hinge 30 on surface 32. Surface 32 as illustrated is shown continuous. This is because receptacle opening 24c is configured to overlap itself when the protector 10 is in the closed position.
  • protector 10 In order to insert a control line in protector 10, protector 10 is bent such that surface 32 becomes N-shape to open receptacle opening 24c, thus allowing a control line to be installed into receptacle bore 26. Protector 10 is then bent back to straighten surface 32, and close receptacle opening 24c around the control line. In such configuration the control line is well protected 360° around the line.
  • Figure 3B is provided which is taken on line 3B-3B in Figure 3A. Alternate overlapping structures visible on the 3B view are illustrated in Figures 3C-3F.
  • receptacle 16d is simply U-shaped and cut into surface 22.
  • the retention of the control line may be provided by an adherent such as a thermo fixed glue or an epoxy formulation or other glue applied to the receptacle before or after installation of the control line.
  • a polymer or other type of stick tape is similarly employable.
  • a receptacle 16e is fully enclosed to both of side 22 and side 32 of protector 10.
  • bore 26e is in fact a closed bore through the center area of a matrix 12.
  • the control line 26 is fed through receptacle bore 26e from one end.
