Definitions

  • the string 12 may include at least one wired pipe segment 14 having an uphole end 18 and a downhole end 16.
  • uphole refers to a location near the point where the drilling started relative to a reference location when the segment 14 is disposed in a borehole
  • downhole refers to a location away from the point where the drilling started along the borehole relative to the reference location. It shall be understood that the uphole end 18 could be below the downhole end 16 without departing from the scope of the disclosure herein.
  • At least an inner bore or other conduit 20 extends along the length of each segment 14 to allow drilling mud or other fiuids to flow therethrough.
  • a transmission line 22 is located within the wired segment 14 to provide protection for electrical, optical or other conductors to be disposed along the wired segment 14.
  • the transmission line 22 is a coaxial cable.
  • the transmission line 22 is formed of any manner of carrying power or data, including, for example, a twisted pair.
  • the transmission line 22 is a coaxial cable it may include an inner conductor surrounded by a dielectric material.
  • the coaxial cable may also include a shield layer that surrounds the dielectric.
  • the shield layer is electrically coupled to an outer conductor that may be formed, for example, by a rigid or semi-rigid tube of a conductive material.
  • the segment 14 includes a downhole connection 24 and an uphole connection 26.
  • the segment 14 is configured so that the uphole connection 26 is positioned at an uphole location relative to the downhole connection 24.
  • the downhole connectoin 24 includes a male coupling portion 28 having an exterior threaded section, and is referred to herein as a "pin end" 24.
  • the uphole connection 26 includes a female coupling portion 30 having an interior threaded section, and is referred to herein as a "box end" 26.
  • the system 10 is operably connected to a downhole or surface processing unit which may act to control various components of the system 10, such as drilling, logging and production components or subs. Other components include machinery to raise or lower segments 14 and operably couple segments 14, and transmission devices.
  • the downhole or surface processing unit may also collect and process data generated by the system 10 during drilling, production or other operations.
  • Embodiments disclosed herein include a surface sub that can be used to allow for communication between the surface unit and communication network comprised of one or more of the wire pipe segments 14.
  • FIG. 4 illustrates a surface sub 40 according to one embodiment that may allow a signal to be communicated from or to a wired pipe segment 14.
  • the signal may be received from or provided to a surface unit such as computing device 44.
  • the signal is carried from the surface unit to the surface sub 40 over communication line 46.
  • the communication line 46 could connect to a wireless device that transmits the signal to another location.
  • the communication line 46 could be omitted and communication from the surface sub 40 to the computing device 46 could be wireless.
  • the illustrated surface sub 40 includes a main body 50 and a communication collar 52.
  • the communication collar 52 and the main body 50 are configured such that they may rotate relative to one another.
  • the main body 50 may be rotated during a drilling operation while the communication collar 52 remains relatively stationary.
  • this may allow for communication between the computing device 44 (or other surface unit) and the wired pipe segment 14/main body 50 as they rotate without causing the communication line 46 to be wrapped around the main body 50 or communication collar 52.
  • the main body 50 includes a box end 72 and a pin end 70 configured so that it can be disposed within the box end 26 of another wired pipe segment 14 to effect a fixed connection there between to connect main body 50 with segment 14.
  • the exterior of the pin end 70 and the interior of the box end 26 of an adjacent pipe segment 14 are tapered and may include interlocking threads on the tapered surfaces.
  • the pin end 70 and the box end 26 are described has having threaded portions, the pin end 70 and the box end 26 may be configured to be coupled using any suitable mechanism, such as bolts or screws or an interference fit.
  • the main body 50 includes at least one transmission device 34 (also referred to as a "coupler" herein) disposed therein located at the pin end 70 and/or the box end 72 thereof.
  • the transmission lines 22 serve to electrically connect the transmission device 34 to an outer surface 73 of the main body 50.
  • the transmission lines 22 disclosed herein can all be of the same type or can be selected from different types.
  • the types include, for example, a coaxial cable, a twisted pair, and a wire.
  • the couplers 131 and 103 are brought into communication with each other.
  • a second bearing 113 held in place by retaining mechanism 137 that may include thread that mate with threads on the outer surface of the main body 50.
  • the first 1 11 and second 113 bearings allow for relative rotation of the assembly that includes the main body 50 and the outer adapter 101 and the communication collar 52.
  • the communication collar 52 includes additional optional housing element 135 that protects and is fixedly coupled to the collar body 107.
