Due to unconventional reservoir have natural weak discontinuities such as natural fractures and bedding planes, the hydraulic fracture has complicated fracture network morphology. Therefore, the traditional fracturing design method and the numerical simulation method of fracture propagation were restricted in the unconventional reservoir. In this paper, the application of the extended finite element method(XFEM), discrete element method(DEM), and displacement discontinuity method(DDM) in the simulation of hydraulic fracturing are discussed, as well as their advantages and disadvantages. It is indicated that XFEM and DEM have strong advantage in small scale mechanism analysis, while DDM has the superiority in the simulation of actual fracturing process in homogeneous formation. Finally, we draw the conclusion that combining two or more numerical simulation methods to simulate the fracture propagation of unconventional reservoirs will be a promising direction.
