| description | For greenhouse gas control and environment protection, CO<sub>2</sub> emission reduction has become a hot spot in global research. CO<sub>2</sub> injection in developed oil reservoirs to enhance oil recovery is widely regarded as one of the most economical and promising measures for reducing anthropogenic CO<sub>2</sub> emissions into the atmosphere. In this paper, a three-dimensional embedded discrete fracture model is proposed and applied to simulate CO<sub>2</sub> flooding and geological storage processes in hydraulically fractured reservoirs. The gas injection is simplified as a two-phase two-component mathematical model with the varying pressure-related fluid physical properties, and its accuracy is verified by commercial software tNavigator<sup>®</sup>. The advantage of this model is that it can deal with the complex geological conditions of three-dimensional arbitrary-inclined fracture networks and accurately assess the effects of CO<sub>2</sub>-EOR and geological sequestration in real reservoirs. Two application cases of CO<sub>2</sub> huff-and-puff with a single well and inter-fracture asynchronous injection and production are demonstrated and explained in detail. The optimized technological parameters and CO<sub>2</sub> saturation distribution can provide key technical parameters for field operations. |
