Piezoelectric transducer is a key component of acoustic well-logging tool. Transducers used in acoustic well-logging tools usually have limited bandwidth, and their dominant frequencies severely drift with drastic change of borehole temperature when

Many oil and gas fields, especially non-conventional shale and compacted sand reservoirs, have formation anisotropy. The acoustic anisotropy measurement of cores in these reservoirs can guide drilling, well logging, and exploitation. However, almost

Well logging is performed in oil and gas exploration wells to obtain the physical characteristics of underground formations. Thereafter, these wells are cased. Through-casing logging is important in mature fields and for wells that are cased without

Acoustic logging while drilling (LWD) technology plays an important role in oil and gas exploration and development. Compared to traditional wireline logging, LWD must address more additional crucial problems, such as great noise confusions. This pap

Acoustic well logging adopts bending vibrators to transform high-voltage electric signals into acoustic signals. Excited acoustic signals have been proven best when the pulse widths are $0.5/{f_0}$ (${f_0}$ refers to the resonance frequencies of the
