    摘要： A method for communicating signals between an instrument in a wellbore and a device at the Earth's surface using a wired drill pipe telemetry channel includes allocating signals generated by at least one instrument in the wellbore to a plurality of buffers. Each buffer represents data having a respective communication priority. Signals from each buffer are communicated to the wired drill pipe telemetry channel according to a predetermined priority procedure. The procedure allocates telemetry channel priority related to the communication priority.

    摘要： A method for synchronizing a clock in a device at the Earth's surface with a device disposed in a wellbore includes generating a time datum for a signal generated at at least one of the surface and in the wellbore proximate an end of the pipe string. A time delay is determined between detection of the signal at the at least one repeater and retransmission of the signal from the at least one repeater. The time datum is appended with a signal corresponding to the time delay. The retransmitted signal is detected at the other of proximate the end of the pipe string and at the surface.

    摘要： Systems and methods provide wireless power and actuation of a downhole component within a borehole formed in a formation. The systems and method have a first downhole component positioned within the borehole and connected to and/or in communication with a power source. A wireless transmitter is electrically connected to the first component and is adapted to wirelessly transmit electrical power. A second downhole component is in communication with the wireless transmitter to receive the electrical power from the wireless transmitter. The second component is actuated upon receiving the electrical power to perform a task related to the borehole or formation about the borehole.

    摘要： Methods and apparatus to configure drillstring communications are described. In one disclosed example, a method to configure drillstring communications involves generating a signal at a transmitter coupled to a drillstring, transmitting the generated signal via the transmitter to a receiver, sampling the transmitted signal at the receiver to generate a received signal, calculating a transmission characteristic based on a comparison of the generated signal and the received signal, and configuring at least one of the transmitter or receiver based on the transmission characteristic.

    摘要： The present disclosure relates to a method to determine a clock signal when separate clocks are used. In one embodiment, a disciplined clock system comprising an update subsystem and a synthesis subsystem is provided. A first clock phase estimate is provided to the update subsystem and used, along with the update subsystem, to determine a frequency offset estimate and a phase offset estimate. The clock signal is determining using the frequency offset estimate, the phase offset estimate, and the synthesis subsystem. Alternatively, two clocks can be synchronized by generating a signal associated with a first clock; modulating the signal; transmitting the modulated signal; receiving the modulated signal by a receiver associated with a second clock; correlating the received signal; determining the time of arrival of the received signal; determining the time difference between the two clocks; and synchronizing the two clocks.
