    摘要: A wireless data telemetry system for use in a drilling system can include a drill head wireless transmitter and at least one data link transceiver. The drill head wireless transmitter can be in a drill head of the drilling system, the drill head wireless transmitter configured to generate and transmit one or more data signals associated with a drilling process. The at least one data link transceiver can be wirelessly coupled to at least one of the drill head wireless transmitter or another data link transceiver, with the drill head wireless transmitter and the at least one data link transceiver configured to be physically coupled within a drill string and spaced apart from one another. The drill head wireless transmitter and the at least one data link transceiver together configured to wirelessly communicate the one or more data signals beyond a transmission range of the drill head wireless transmitter.

    摘要: A plug assembly for a cementing operation in a well includes a bottom wiper plug configured to land in or near the toe of a well and receive a cement slurry therethrough, a top wiper plug releasably coupled to the bottom wiper plug and configured to land on the bottom wiper plug after the cement slurry is received through the bottom wiper plug, a bridge plug coupled to the top wiper plug and configured to move toward the bottom wiper plug with the top wiper plug after the bottom wiper plug is landed in or near the toe of the well, and a sensor sub coupled to the bridge plug and configured to detect a gate in the well.

    摘要: A system for tracking a below-ground transmitter from an aerial receiver. The receiver has an antenna assembly, a processor, and a propulsion system. The antenna assembly detects the magnetic field from an underground transmitter and generates an antenna signal. The processor is programmed to receive the antenna signal and generate a command signal, which moves the receiver to a position above the transmitter. Once in the desired position, which may be a reference plane at a fixed elevation, the antenna assembly measures the magnetic field to determine the location of the drill bit along borepath.
