Abstract: Studying the acoustic characteristics of layered shales contributes to applying acoustic logging to guide drilling safely. The shale samples were collected from the Lower Silurian Longmaxi Formation in Changning area of Sichuan Basin, and drilled into cores along different orientation relative to the bedding plane. Based on multi-frequency ultrasonic wave testing system, acoustic wave experiments of shale samples were carried out and the influences of bedding angle on acoustic wave velocity, attenuation coefficient, time domain and frequency domain were analyzed. Numerical simulation experiments were carried out to analyze the influences of bedding density on wave velocity and attenuation in parallel and vertical core end faces. The results show that the interval transit time and the attenuation coefficient increase linearly with the increase of bedding angle. Frequency dispersion phenomenon exists, which shows that the acoustic velocity varies with the testing frequency. Acoustic velocity is negatively correlated with bedding density, and bedding angle has no effect on the dominant frequency of shale acoustic waves. The results provide a reference for the drilling and fracturing engineering of shale gas wells.

Key words: shale, bedding angle, bedding density, acoustic wave, Longmaxi Formation, Sichuan Basin
