摘要： 在大庆油田油水条件下, 利用界面张力仪、 泡沫扫描仪及泡沫驱油装置, 考察了非离子G e m i n i表面活 性剂与聚合物二元体系的界面性能、 泡沫性能及驱油效果。结果表明, 二元体系可以与大庆原油形成超低界面张 力, 但随非离子G e m i n i表面活性剂或聚合物浓度增加, 二元体系界面张力升高。二元体系的泡沫综合指数随非离子 G e m i n i表面活性剂和聚合物浓度增加出现极大值, 而后降低。非离子 G e m i n i表面活性剂或聚合物浓度增加, 二元 泡沫复合驱采收率增加。随着气液体积比的增大, 二元泡沫复合驱采收率先增大后减小。在气液体积比为1∶1时, 二元泡沫驱采收率达到最大, 气液体积比过大, 易发生气窜。二元泡沫复合驱采收率随着压力升高而降低。

Abstract: The binary system properties including interfacial tension, foam properties and oil displacement effect of nonionic Gemini surfactant and polymer were studied using interfacial tensiometer, foam scanner and foam flooding equipment. The results showed that the binary system had the ultralow surface tension with Daqing crude oil. The surface tension of binary system was increased with rising concentration of nonionic Gemini surfactant and polymer. The foam index of binary system had a maximum when concentration of nonionic Gemini surfactant and polymer was increased. The binary foam composite flooding recovery was increased with rising concentration of nonionic Gemini surfactant and polymer. As gas liquid ratio was improved, the binary foam composite flooding recovery first increased, and then decreased. When the gas liquid ratio was 1∶1, the oil displacement effect was best. The phenomenon of gas breakthrough occurred easily when the gas liquid ratio was bigger, and then the oil recovery effect declined. The higher the pressure was, the worst the foam flooding recovery effect was.
