Abstract—The development of unconventional gas reservoirs has become an increasing component of the world natural gas supply. Shale gas has become an important new energy, and more and more scientists are studying it. Many scientific studies have shown that the fractures play a vital role in the development of shale gas reservoir, and the precise impacts need additional analysis. This paper aims to check the influence of fracture geological characteristics on shale gas flow using the numerical simulation method. We established mathematical models and geological model of shale gas matrix block and fractures respectively. The geological model consists of the shale matrix block and fractures. After discretization of the model, we use the finite element method to solve the model. In this paper, we tend to analyse the influence of geological features such as fracture dip, fracture density, and fracture area on shale gas flow. The results showed that the gas flow rate performance varies with the fracture geological features. Therefore, when we develop shale gas reservoirs, the fracture geological characteristics ought to be taken seriously.
