【摘要】 氮气泡沫在多孔介质中的稳定性如何,是氮气泡沫应用于边底水油藏堵水、压水锥的关键因素．本研究模拟地层条件,采用搅拌法优选了不同种类的起泡剂,确定了起泡剂和稳泡剂的最佳浓度,并按照该浓度进行了氮气泡沫在多孔介质中的稳定性实验．实验结果表明, 氮气泡沫在多孔介质中具有良好的稳定性．更多还原

【Abstract】 The stability of nitrogen foam in porous media is the key element during water shut off and water coning pushing treatment in the reservoir which has edge water or bottom water.The optimal foamer,optimal concentrations of foamer and foam stabilizer are determined using stirring experiment method and simulating reservoir condition,the nitrogen foam stability experiment is also carried out with optimal concentration,the result shows that nitrogen foam has well stability in porous media.更多还原
