Based on Hudson equivalent medium model and Schoenberg linear sliding model theory, a fracture equivalent medium model suitable for sonic logging is proposed, and the equivalent elastic parameter expression of the inclined fracture is derived. Using the established equivalent medium model, the effects of fracture density, width, dip angle and fillings on formation P-wave velocity and anisotropy information obtained from sonic logging were studied, which provides a theoretical basis for evaluating fractured formations using acoustic logging data.
