摘　　要：泡沫因其贾敏效应突出、油水选择性强等优点,是一种有一定封堵能力,改善吸水剖面的调驱化学剂。但塔河油田具有高温高盐的特性,泡沫结构在高温高盐条件下容易丧失自身的优良特性,发生性质和形态上的改变,本研究根据泡沫的这一现象剖析高盐、高温地层条件影响泡沫性质、形态的深层原因,为提升泡沫稳定性做了必要的理论准备,并叙述了耐温抗盐两相泡沫体系、3种三相泡沫体系及相关实例,目前固—液—气三相泡沫的耐温抗盐性能较好,有利于相关研究人员深耕泡沫调驱技术市场,深入探讨塔河油田缝洞型油藏氮气泡沫调驱技术的发展方向。Because of its prominent jamin effect and strong selectivity of oil and water,foam is a kind of flooding chemical agent to improve water absorption profile.However,Tahe oilfield has the characteristics of high temperature and high concentration of salt,and the foam structure is easy to lose its excellent characteristics under the condition of high temperature and high concentration of salt,and change its properties and forms.Based on this phenomenon of foam,this study analyzed the deep reasons for the influence of high concentration of salt and high temperature formation conditions on the properties and forms of foam,and made necessary theoretical preparations for improving the stability of foam.The influence factors of foam stability under high temperature and high concentration of salt conditions,temperature and salt resistance two-phase foam system,three kinds of three-phase foam system and relevant examples are described.Currently,the solid-liquid-gas three-phase foam has good temperature and salt resistance performance,which is conducive to the relevant researchers to further explore the foam flooding technology,and further explore the development direction of nitrogen foam flooding technology in fractured-cavity reservoir of Tahe oilfield.
