In this paper, considering the tuning effects of single fractured thin layer based on Chapman’s multi-scale rock physical model, we discuss the frequency-dependent effects as the various of type of fluid, fracture density and fracture scale. The fracture in our study is horizontal, making the media a VTI model. We find that the influence of the fracture density and scale can be restricted by the types of fluid. We modeled the frequency-dependent reflection coefficients of a set of thin inter-bed layers. Our study shows that fluid cannot cause the changes of the tuning thickness in the absence of fractures. The analysis of modeling results also verifies that fracture can strengthen energy at low frequency and weaken energy at high frequency. But it depends on the internal structure of the layers and the type of fluid weather low frequency bright spots comes out.
