摘要：

For the purpose of greenhouse gas control and environment protection, CO2 emission reduction has become a hot spot in global research. CO2-EOR and geological storage are widely regarded as one of the most economical and promising emission reduction measures. In this paper, the 3D embedded discrete fracture model (EDFM) is built to simulate the interfracture CO2 flooding and geological storage process in fractured reservoirs. This model can deal with the complex geological conditions of three-dimensional arbitrary inclined fracture networks, significantly improve the calculation efficiency, and accurately evaluate the CO2-EOR process of real reservoirs. The obtained CO2 reserves and saturation distribution can provide key technical parameters for field operations.
