Abstract

An embodiment of a communication system for communicating between a wired pipe string in a borehole and a surface location includes at least a first wired pipe downhole component and a second wired pipe downhole component in the wired pipe string, a coupler configured to transmit a transmission signal between the first wired pipe downhole component and the second wired pipe downhole component, and a wireless transmission assembly in at least one of the first wired pipe downhole component and the second wired pipe downhole component. The wireless transmission assembly is configured to wirelessly transmit a wireless transmission signal to a receiver antenna, and the receiver antenna is disposed at the surface location and configured to receive the wireless transmission signal.

First claim

What is claimed is:

1. A communication system for communicating between a wired pipe string in a borehole and a surface location, comprising:
at least a first wired pipe downhole component and a second wired pipe downhole component in the wired pipe string, wherein at least one of the first wired pipe downhole component and the second wired pipe downhole component is an uppermost wired pipe downhole component, the uppermost wired pipe downhole component including an upper end and a lower end;
a coupler in the upper end of the uppermost wired pipe downhole component, the coupler configured to transmit a transmission signal between the first wired pipe downhole component and the second wired pipe downhole component; and
a transmission assembly proximate to the upper end of the uppermost wired pipe downhole component, the transmission assembly including a transmitter configured to wirelessly transmit the transmission signal to a receiver antenna when the uppermost wired pipe downhole component and the transmission assembly are at a first surface location, the receiver antenna disposed at a second surface location and configured to receive the transmission signal.

2. The system of claim 1 , further comprising a surface communication interface at a third surface location configured to communicate with the bottom hole assembly through the wired pipe string using the transmission signal, wherein the transmitter is configured to transmit a transmission signal and the receiver antenna is configured to receive the transmission signal when the uppermost wired pipe downhole component is physically disconnected from the surface communication interface.

3. The system of claim 1 , further comprising a conversion device, the conversion device configured to convert the transmission signal from a short range electrical wireless signal having a first range to a long range electrical wireless signal having a second range.

4. The system of claim 1 , wherein the coupler is configured to transmit the transmission signal at a first frequency, and the transmission assembly is configured to transmit the transmission signal at a second frequency that is different than the first frequency.

5. The system of claim 1 , further comprising a switching mechanism configured to convert the transmission signal to the wirelessly transmitted transmission signal in response to at least one of: a message from a downhole processing device and a signal from a manual switch.

6. The system of claim 1 , further comprising a detection mechanism configured to perform at least one of: detecting when the first or second wired pipe downhole component is the uppermost wired pipe downhole component and identifying which of the first and second wired pipe downhole components is the uppermost wired pipe downhole component.

7. The system of claim 6 , further comprising a switching mechanism configured to switch from communication using the coupler to communication using the transmission assembly based on a signal from the detection mechanism.

8. The system of claim 1 , further comprising at least one sensor, the at least one sensor selected from at least one of: a pressure sensor, a temperature sensor, a magnetometer, an accelerometer, a formation evaluation sensor, a bending sensor and a cement evaluation sensor, the transmission signal configured to transmit data provided by the at least one sensor.

9. The system of claim 1 , wherein the transmission assembly is a bi-directional transmission assembly.

10. The system of claim 1 , wherein the transmission assembly is located at one of: the coupler, an outer surface of the uppermost wired pipe downhole component, and an inner surface of the uppermost wired pipe downhole component.

11. The system of claim 1 , wherein the transmission assembly is part of a wireless network.

12. The system of claim 1 , wherein the wired pipe string is used in a tripping operation.

13. The system of claim 2 , wherein the uppermost wired pipe downhole component is physically disconnected from the surface communication interface when the uppermost wired pipe downhole component is unable to communicate with the surface communication interface using a wired communication device, or a short range communication device.

14. A method of communicating between a wired pipe string in a borehole and a surface location, comprising:
disposing the wired pipe string in a borehole in an earth formation and connecting the wired pipe string to surface equipment, the wired pipe string including at least a first wired pipe downhole component and a second wired pipe downhole component, wherein at least one of the first wired pipe downhole component and the second wired pipe downhole component is an uppermost wired pipe downhole component, the uppermost wired pipe downhole component including an upper end and a lower end, and a coupler in the upper end of the uppermost wired pipe downhole component, the coupler configured to transmit a transmission signal between the first wired pipe downhole component and the second wired pipe downhole component; and
wirelessly transmitting the transmission signal from a transmitter of a transmission assembly proximate to the upper end of the uppermost wired pipe downhole component when the uppermost wired pipe downhole component and the transmission assembly are at a first surface location, the transmission signal wirelessly transmitted to a receiver antenna disposed at a second surface location.

15. The method of claim 14 , further comprising receiving the transmission signal at a conversion device, and converting the transmission signal to the wirelessly transmitted transmission signal.

16. The method of claim 15 , wherein converting is performed in response to at least one of: a message from a downhole processing device and a signal from a manual switch.

17. The method of claim 14 , further comprising receiving the transmission signal at a conversion device, and converting the transmission signal from a short range electrical wireless signal having a first range to a long range electrical wireless signal having a second range, the first range being less than the second range.

18. The method of claim 14 , wherein the transmission signal is transmitted at a first frequency by the coupler, the method further comprising receiving the transmission signal at a conversion device, and converting the transmission signal to the wirelessly transmitted transmission signal having a second frequency that is different than the first frequency.

19. The method of claim 14 , further comprising a detection mechanism configured to perform at least one of: detecting when the first or second wired pipe downhole component is the uppermost wired pipe downhole component and identifying which of the first and second wired pipe downhole components is the uppermost wired pipe downhole component.
