摘要： Multipole acoustic logging-while-drilling (LWD) tools and associated methods are disclosed herein. In some embodiments, the disclosed acoustic LWD tool comprises a transmitter array and at least one receiver array. The transmitter array generates acoustic waves with an excitation pattern having a cutoff frequency greater than about 3 kHz. The receiver array is spaced apart from the transmitter array and is configured to detect said acoustic waves. Some of the disclosed method embodiments comprise: generating multipole acoustic waves in a fluid-filled borehole using an excitation pattern with a cutoff frequency greater than about 3 kHz; selectively detecting acoustic waves that propagate with said excitation pattern; and determining an acoustic shear wave slowness for a formation penetrated by the borehole.

摘要： A method of processing acoustic waveform data is disclosed. An acoustic logging tool acquires acoustic waveform data. An adaptive frequency filter is determined. The acoustic waveform data is filtered using the adaptive frequency filter. A formation slowness is determined from the filtered acoustic waveform data. The lower bound of the adaptive frequency filter may be determined using a polynomial function of a minimum excitement frequency parameter, a slowness parameter, and a third parameter. The upper bound of the adaptive frequency filter may be determined using a polynomial function of a peak excitement frequency parameter, the slowness parameter, and the third parameter.

摘要： Various disclosed acoustic logging systems and methods compensate for logging tool tilt relative to the borehole axis. Some method embodiments include: generating an acoustic signal that propagates along a borehole in a formation; receiving a signal from each of a set of azimuthally-arranged acoustic transducers; processing the signals to compensate for logging tool tilt; and determining a property of the formation based at least in part on the compensated signals. Some tool embodiments include an internal controller that processes signals from different directions to determine and correct time offsets that are attributable to logging tool tilt. Thereafter, the tilt-compensated signals can be used to measure formation and borehole parameters which may be associated with position and displayed in the form of borehole logs and/or images.
