Abstract

A wired pipe joining system for joining wired pipe segments having first end, a second end, a first coupler in the first end, a second coupler in the second end, and a transmission medium in communication with the first and second couplers. The system includes: a lower clamp configured to hold a top pipe segment; a top rotation arm to guide a first end of a new pipe segment into a second end of a top pipe segment; a top coupler measurement device configured to connect to a second end of the new pipe segment and receive a signal from a second coupler in the second end of the new pipe segment; and a controller that causes the top rotation arm to move the new pipe segment to cause the signal received by the top coupler measurement to be maximized.

First claim

What is claimed is:

1. A wired pipe joining system for joining wired pipe segments having first end, a second end, a first signal transmission device in the first end, a second signal transmission device in the second end, and a transmission medium in communication with the first and second signal transmission devices, the system comprising:
a lower clamp configured to hold a top pipe segment;
a top rotation arm to guide a first end of a new pipe segment into a second end of a top pipe segment;
a top coupler measurement device configured to connect to a second end of the new pipe segment and receive a signal from the second signal transmission device in the second end of the top pipe segment; and
a controller that causes the top rotation arm to move the new pipe segment to cause the signal received by the top coupler measurement device to be maximized.

2. The wired pipe joining system of claim 1 , wherein the signal transmission device is in a repeater in a box end of the top pipe segment.

3. The wired pipe system of claim 1 , wherein at least one of the first and second signal transmission devices in the top pipe segment is an inductive coupler.

4. The wired pipe system of claim 1 , wherein at least one of the first and second signal transmission devices in the top pipe segment is a resonant coupler.

5. A method of joining wired pipe segments having first end, a second end, a first signal transmission device in the first end, a second signal transmission device in the second end, and a transmission medium in communication with the first and second signal transmission devices, the method comprising:
placing a top pipe segment into a lower clamp of a pipe joining device;
placing a new pipe segment into a top rotation arm of the pipe joining device;
causing a signal to be presented on the second signal transmission device of the top pipe segment;
determining an amplitude of the signal as received by a top coupler measurement device coupled to a second end of the new pipe segment;
moving, due to a controller, the new pipe segment to maximize the amplitude; and
rotating the new pipe segment to join it to the top pipe segment.

6. The method of claim 5 , wherein the signal received by the top coupler measurement device is generated by a repeater in the top pipe segment.

7. The method of claim 5 , wherein the signal received by the top coupler measurement device is generated by a bottom hole assembly.

8. The method of claim 5 , wherein at least one of the first and second signal transmission device in the top pipe segment is an inductive coupler.

9. The method of claim 5 , wherein at least one of the first and second signal transmission device in the top pipe segment is a resonant coupler.
