The computation mesh is a basic factor for reservoir simulation. The traditional mesh generation method restricts the development of numerical simulation technology of shale gas reservoir with complex fracture network. Therefore, it is of great significance to establish an efficient mesh generation method for fractured medium. On the basis of fracture nodes, an adaptive mesh method (AMM)is established based on the principles of pixel point and distance nearest as well as the logarithmic encryption method. The AMM can handle the arbitrary complex network with a small number of grids, showing high computing precision. The results show that the control area of fractured grid in AMM is closer to the actual situation than that in NFFLOW; AMM can also handle any arbitrary complex fracture network and complex boundary condition model. Compared with the existing mesh method, AMM greatly reduces the number of computational grids. When performing numerical simulation for shale gas reservoirs, AMM can solve the problems such as large amount of computational grids and low precision caused by complex fractures, so as to lay a foundation for the numerical simulation of field-scale shale gas reservoirs.
