STEERABLE TRANSCEIVER UNIT FOR DOWNHOLE DATA ACQUISITION IN A FORMATION

摘要

A method and apparatus for collecting data downhole in a well bore, even during drilling operations, are disclosed. The apparatus generally comprises an antenna and some associated electronic circuitry. The antenna includes a plurality of arrayed transceiver elements and the electronic circuitry steers transmission or reception throu gh the antenna by controlling the application of power to the array elements. In operation, a transceiver unit containing such an antenna is positioned proximate a remote sensor placed in to a formation. An electromagnetic signal is then steered to communicate with the remote sensor over a wireless link.
