Oil recovery mechanisms of CO2 foam flooding in low permeability fractured carbonate reservoir
对低渗裂缝性碳酸盐岩油藏开展了CO2泡沫驱渗流特征研究,采用野外碳酸盐岩露头进行岩心驱替实验,剖析CO2泡沫驱增产机制及效果,基于实验数据,建立了考虑碳酸盐岩储层特征及泡沫动态演化的CO2泡沫驱渗流新模型.结果表明,CO2泡沫驱能显著改善波及剖面,提升水驱后期开发效果,新模型能有效预测泡沫驱各相时空演化规律及驱油效率,并明确泡沫驱渗流机理及主控因素.
The flow characteristics of CO2 foam flooding are thoroughly investigated in low permeabili-ty fractured carbonate reservoir.The enhanced oil recovery mechanisms of CO2 foam flooding were analyzed by performing core flooding experiment in carbonate outcrops.Then,a new mechanistic model of CO2 foam flooding was proposed by considering carbonate reservoir characteristics and foam evolution dynamics.The results show that CO2 foam flooding can significantly improve the sweep profile and enhance the performance of waterflooding at the later stage;meanwhile,the new model can effectively predict the space-time evolution characteristics of each phase of CO2 foam flooding and the oil displacement efficiency,as well as clarify the flow mechanisms and main controlling factors of CO2 foam flooding.
