摘　　要：为进一步完善驱油用发泡剂的静态泡沫性能表征参数,提出用静态泡沫综合定量指数(I_(SFCQI))表征发泡剂的静态泡沫性能,应用I_(SFCQI)表征一元、二元和三元发泡剂的静态泡沫性能,分析I_(SFCQI)与泡沫驱采收率的相关性。结果表明I_(SFCQI)可以表征发泡剂的起泡体积、泡沫稳定性、泡沫携液量和泡沫携液稳定性4个静态泡沫性能参数,初步实现用一个参数快速定量表征发泡剂的静态泡沫性能;三元发泡剂的I_(SFCQI)大于二元发泡剂的,二元发泡剂的I_(SFCQI)大于一元发泡剂的;发泡剂的I_(SFCQI)与泡沫驱采收率具有正相关性。In order to further improve the static foam performance characterization parameters of foaming agent for oil displacement,the static foam comprehensive quantitative index(I_(SFCQI))was proposed to characterize the static foam performance parameters of foaming agent.The I_(SFCQI) was applied to characterize the static foam properties of the unitary,binary and ternary foaming agents.The relationship between I_(SFCQI) and foam flooding recovery was analyzed as well.The experimental results show that the I_(SFCQI) can be used to characterize the four static foam performance parameters,such as foaming volume,foam stability,foam liquid carrying capacity,and foam liquid carrying stability.This has achieved a quick and quantitative evaluation of static foam performance by using one parameter.It is also found that the I_(SFCQI) of the ternary foaming agent is greater than that of the binary foaming agent,and the I_(SFCQI) of the binary foaming agent is greater than that of the unitary foaming agent.The I_(SFCQI) of foaming agent shows positive correlation with foam flooding recovery.
