摘要： A sensor assembly for sensing downhole parameters is provided. The sensor assembly is positionable in a downhole tool deployable into a subterranean formation to form a wellbore. The sensor assembly includes a carrier positionable in the downhole tool, at least one set of three accelerometers, and at least one set of three magnetometers. The carrier includes at least one set of three receptacles. The three receptacles are positioned radially about a periphery of the carrier at equal distances thereabout. The set of three accelerometers are correspondingly positionable in the at least one set of three receptacles, and the set of three magnetometers are correspondingly positionable in the at least one set of three receptacles. The set of three magnetometers includes two physical magnetometers and one virtual magnetometer. The virtual magnetometer is produced from the two physical magnetometers.

摘要： A device for communicating with a downhole measurement tool includes a processor module comprising a set of commands and configured to issue a command from the set to the downhole tool and receive a corresponding reply from the downhole tool. The set of commands includes at least one of a command to switch the downhole measurement tool between a sleep mode and an active mode and a command to download data from the downhole measurement tool. The device includes a transceiver module coupled to the processor module and an antenna coupled to the transceiver module. The antenna and transceiver module are configured to transmit commands and replies between the processor module and the downhole measurement tool.
