Shale gas contains three kinds of flow mechanism, which are seepage, analytical attachment and spread, the situation is very complicated, so there is no substantial and breakthrough progress about 3D geological modeling of shale gas. The unique complex fracture system of shale gas is directly related to the result of numerical simulation, so the accurate representation of the complex fracture network system and the characteristics of the shale gas flow is the key to the simulation of the natural fracture and hydraulic fracturing. In this paper, combined with the exploration and development of Sichuan shale gas Y block, the preliminary study on the geological modeling of shale gas can provide useful reference for the numerical simulation of shale gas fine reservoir.
