Abstract
Description
- This application is a continuation of U.S. application Ser. No. 14/012,459 filed Aug. 28, 2013, the disclosure of which is incorporated by reference herein in its entirety.
- During subterranean drilling and completion operations, a pipe or other conduit is lowered into a borehole in an earth formation during or after drilling operations. Such pipes are generally configured as multiple pipe segments to form a “string”, such as a drill string or production string. As the string is lowered into the borehole, additional pipe segments are coupled to the string by various coupling mechanisms, such as threaded couplings.
- Various power and/or communication signals may be transmitted through the pipe segments via a “wired pipe” configuration. Such configurations include electrical, optical or other conductors extending along the length of selected pipe segments. The conductors are operably connected between pipe segments by a variety of coupling configurations.
- One such coupling configuration includes a threaded male-female configuration often referred to as a pin box connection. The pin box connection includes a male member, i.e., a “pin” that includes an exterior threaded portion, and a female member, i.e., a “box”, that includes an interior threaded portion and is configured to receive the pin in a threaded connection.
- Some wired pipe configurations include a transmission device mounted on the tip of the pin as well as in the box end. The transmission device, or “coupler,” can transmit power, data or both to an adjacent coupler. The coupler in the pin end is typically connected via a coaxial cable to the coupler in the box end.
- One feature of a wired pipe system is that in can transmit data from a “downhole” location to the surface rapidly and vice versa. A surface communication interface (referred to as surface communication sub herein) may be used to take a signal from or put a signal into the wired pipe.
- Disclosed herein is a sub for a wired pipe system that includes a body including an outer surface and a pin end and a first transmission device located in or near the pin end. The sub also includes a communication collar that at least partially surrounds the outer surface and that is rotatable relative to the body, a second transmission device in electrical communication with the first transmission device and a transmission line that electrically connects the first and second communication devices and that passes at least partially through the body. The sub further includes a third transmission device located in the communication collar in communication with the second transmission device. In the disclosed sub, the first, second and third transmission devices are all of the same type.

transmission device 34 is configured to provide communication of at least one of data and power betweensurface sub 40 andsegments 14 when thepin end 70 and thebox end 26 are engaged. It shall be understood that thetransmission device 34 could also be included in a repeater element or any other device disposed between thesurface sub 40 and adjacent segment 14 (e.g., within the box end thereof). Regardless of the configuration, it shall be understood that eachtransmission device 34 can be connected to one ormore transmission lines 22. Thetransmission device 34 can be any type of device capable transmitting signals across a connection between components in a wired pipe system. Examples include, without limitation, resonant couplers, inductive couplers, galvanic couplers and capacitive couplers. Thetransmission lines 22 serve to electrically connect thetransmission device 34 to anouter surface 73 of themain body 50. Thetransmission 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. - With reference now to
FIG. 5 , a more detailed depiction of portions of thesurface sub 40 are illustrated. Themain body 50 of thesurface sub 40 includes anouter surface 73. Apassage 140 connects theouter surface 73 to a coupler (not shown) located in either apin 70 orbox 72 end (FIG. 4 ) of thesurface sub 40. Thepassage 140 is sized and configured to allow for passage of atransmission line 22 from the box/pin end to theouter surface 73. In this manner, a signal may be communicated in either direction between theouter surface 73 and a coupler located in the pin or box end of thesub 40. - In one embodiment, an
outer adapter 101 is fixedly coupled to theouter surface 73. It shall be understood that theouter adapter 101 could be omitted. Theouter adapter 101 includes atransmission device 103 in electrical communication with the transmission device in the pin/box end of themain body 50. For instance, thetransmission device 103 may be electrically connected to the transmission device in the pin/box end of themain body 50 bytransmission line 22. As such, it shall be understood that thetransmission line 22 illustrated inFIG. 5 passes at least partially through themain body 50. In operation, themain body 50 and theouter adapter 101 are fixedly attached to one and do not rotate relative to one another. As illustrated, ascrew 105 is used to form such connection. - It shall be understood that the
outer adapter 101 could be omitted. In such a case, thetransmission device 103 could be located at or near theouter surface 73. For instance, thetransmission device 103 could be located in a groove formed inmain body 50. - In one embodiment, the
communication collar 52 at least partially surrounds theouter surface 73 and that is rotatable relative to themain body 50. Thecommunication collar 52 includes atransmission device 131 that can communicate with thetransmission device 103 as the two are rotated relative to one another (or when they are not rotating). The communication may be made via electric, resonant, inductive or galvanic coupling. In one embodiment, all of thetransmission devices transmission devices - A
communication line 133 may carry signals to and fromtransmission device 131 though acollar body 107 to anoutput terminal 109. Theoutput terminal 109 can either allow thecommunication line 133 to exit thecommunication collar 52 or may contain a wireless transmitter. - With further reference to
FIG. 5 , an example of how to assemble thesub 40 is provided. Theouter adapter 101 is fixed to theouter surface 73 of themain body 50. Theouter adapter 101 is fixed byscrew 105 in the illustrated embodiment but alternative methods of securing theouter adapter 101 to theouter surface 73 may be employed. Afirst bearing 111 is disposed about theouter surface 73 and held in place by, for example, a retainingring 115. As illustrated, thefirst bearing 111 abuts theouter adapter 103 but this is not required. Thecollar body 107 is then fitted about themain body 50. Thecollar body 107, in one embodiment, carriescoupler 131. As thecollar body 107 is fitted about themain body 50, thecouplers second bearing 113 held in place by retainingmechanism 137 that may include thread that mate with threads on the outer surface of themain body 50. The first 111 and second 113 bearings allow for relative rotation of the assembly that includes themain body 50 and theouter adapter 101 and thecommunication collar 52. In the illustrated embodiment, thecommunication collar 52 includes additionaloptional housing element 135 that protects and is fixedly coupled to thecollar body 107. - In support of the teachings herein, various analyses and/or analytical components may be used, including digital and/or analog systems.
