摘要:

利用扩张压缩界面张力仪和泡沫扫描仪对CO2同FCY(两性离子泡沫剂)形成泡沫稳定性进行研究,研究了动态表面张力、粘弹变量、携液系数、稳定系数之间关系,粘弹变量同再生能力之间关系。研究表明,泡沫稳定性主要受到携液能力和形变能力的影响,表现为随着携液能力的增加体系的稳定性增加;粘弹变量的增加提高了体系的稳定性,两者之间表现出明显的线性关系。泡沫体系的再生能力与体系的形变能力有着密切的关系,随着粘弹变量的增加,体系的再生能力下降。泡沫体系的粘弹变量范围须同时满足体系稳定性和再生性的要求。

Abstract: The influence factor on the stability of foam system formed by CO2 and FCY is researched with foam scanner and interfacial tension meter. The relations among surface tension, modulus, foam entrainment and foam stability are systematically analyzed, The relation of the modulus and rebirth ability is explained, too. It is recognized that Entrainment ability and deformation ability influence foam stability mostly. The increase of entrainment ability and deformation ability enhances the foam stability, rebirth ability of foam system is effected by deformation ability, the increase of modulus makes the rebirth ability drop. The bound of modulus for foam system must meet the request of foam stability and rebirth ability.

Key words: foam flooding, CO2, modulus, entrainment ability, deformation ability, rebirth ability, foam stability
