ABSTRACT:
An acoustic logging tool having an acoustic transmitter and at least one acoustic receiver longitudinally spaced from the transmitter is lowered into a borehole fluid within a tubular member having a known resonant frequency. A pulse of acoustic energy is then transmitted into the tubular member, and acoustic energy traversing the tubular member and formation is detected at the acoustic receiver. A frequency domain transformation is performed on the detected acoustic energy and a cement bond evaluation is performed by comparing transformed detected acoustic energy amplitudes within a predetermined range of the resonant frequency of the tubular member, effectively filtering out acoustic energy which traverses the formation surrounding the tubular member.
