摘要： An acoustic tool that provides a programmable source waveform is disclosed. Numerous advantages may be achieved from the configurability of the source waveform. Notably, acoustic logs at multiple frequencies may be acquired with a single pass. The waveform may be frequency-adapted to maximize formation response and amplitude adapted for gain control. In one embodiment, the acoustic tool comprises: a controller, a digital-to-analog controller (DAC), an acoustic transducer, and a linear driver. The DAC converts a digital waveform from the controller into an analog waveform. The acoustic transducer converts an electrical signal into an acoustic signal. The linear driver receives the analog waveform from the DAC and responsively provides the electrical signal to the acoustic transducer. The electrical signal is proportional to the analog waveform. The tool may further include a memory for storing the digital waveform and/or software for generating the digital waveform.

摘要： An acoustic imaging tool, logging system and method are disclosed for producing high-resolution three-dimensional images. The imaging tool may include three separate arrangements of acoustic transducers: a circumferential set for wall inspection, internal transducers for fluid characterization within a chamber open to wellbore fluid, and forward-looking transducers located at the bottom end of the tool. Forward-looking transducers emit ultrasonic waves and receive reflections back when solid features are located under the tool. In some embodiments, Doppler effect calculations may be performed to produce forward-looking acoustic images. In other embodiments, an ambient acoustic energy illuminates the wellbore, and an acoustic lens set focuses reflected ultrasonic waves onto an acoustic imaging array of an ultrasonic camera.
