Abstract
Movable transducer designs used in downhole environments increase the efficiency of the transmitter and receivers, thereby obtaining improved logging data. In one embodiment, the transmitter/receivers are tilted/rotated to direct the strongest acoustic wave pressure to the critical path for increasing signal strength. In other embodiments, the transmitter/receiver may be extended outwardly toward the formation, or retracted inwardly from the formation. An adaptive algorithm is provided to rotate the transmitter/receiver to match the critical angle when the formation slowness changes. Also, a transmitter/receiver port may be designed to have a cone-shape that matches the impedance of the acoustic wave to the surrounding environment.
