Abstract
Studies on the wetting effect reveal that slip is prevalent at the fluid–solid interface, and its influence cannot be disregarded in microscopic systems. The traditional understanding of the propagation rules and characteristics of elastic waves in fluid-saturated porous media are challenged by the introduction of slip boundary effect. In this paper, the influence of slip boundary effect on the dispersion and attenuation of both shear horizontal guided waves and Love waves in a fluid-saturated porous media is investigated. The virtually enlarged pore model is employed to characterize the degree of slip and the wetting effect with the slip length. It is found that both velocity and attenuation of shear horizontal guided waves in monolayer are sensitive to slip boundary effect, while only attenuation shows sensitivity for Love wave with no significant impact observed on its velocity. The research results fill a gap in understanding how slip boundary effect affects the propagation of shear horizontal and Love waves in fluid-saturated porous media, which is of great significance for the identification of sediment type, physical property inversion and reservoir evaluation.
