For the trends of global climate warming, it is great important to implement the Carbon capture and storage (CCS) technology. This paper describes the numerical simulation of CO2 displacement enhanced oil recovery (EOR) in M reservoir. The M reservoir is an extra-thick buried hill fractured reservoir, which use overlap alternative horizontal well pattern to produce. Considering the time-varying effects of fracture’s porosity and permeability parameters, combining the develop dynamic and the diversification of physical property parameters of fractured formation, use the dual porosity dual permeability model and the three-dimensional components simulator to simulate the develop process. By CO2 WAG orthogonal experiment design, can simulate and predict the development effect of fractured buried hill reservoir affected by factors such as: different production and injection well pattern, injection intensity, gas water slug ratio, alternating cycle and so on. The results show that in the process of CO2 WAG can significantly reduce the risk of gas breakthrough by overlap alternative horizontal well pattern, and reduce the negative impact by fracture properties, also can improve EOR and CO2 sequestration effectively. On this basis, this paper evaluates the suitability of WAG development methods to fractured buried hill reservoir with overlap alternative horizontal well pattern, also optimizes the reasonable development plan for M reservoir.
