Study on Nitrogen Foam Flooding in Fractured Reservoir

Abstract:

Aiming at the heterogeneity characteristics of fractured reservoir, a new type of nitrogen foam flooding agents is proposed. The gas/liquid ratio of nitrogen foam flooding is selected as 3:1, and the injection rate is selected as 3mL/min by the evaluation of foam resistance factor using core flooding equipment. In addition, this foam system has a better performance in the situation of low oil saturation. The results of nitrogen foam flooding show that it can enhance oil recovery by 38% after water flooding using artificial cuboid fractured core, indicating this nitrogen foam formula is suitable for EOR in fractured reservoir.
