| 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(ISFCQI)表征发泡剂的静态泡沫性能,应用ISFCQI表征一元、二元和三元发泡剂的静态泡沫性能,分析ISFCQI与泡沫驱采收率的相关性。结果表明ISFCQI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ISFCQI大于二元发泡剂的,二元发泡剂的ISFCQI大于一元发泡剂的;发泡剂的ISFCQI与泡沫驱采收率具有正相关性。

| Abstract: | In order to further improve the static foam performance characterization parameters of foaming agent for oil displacement,the static foam comprehensive quantitative index(ISFCQI)was proposed to characterize the static foam performance parameters of foaming agent.The ISFCQI was applied to characterize the static foam properties of the unitary,binary and ternary foaming agents.The relationship between ISFCQI and foam flooding recovery was analyzed as well.The experimental results show that the ISFCQI 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 ISFCQI of the ternary foaming agent is greater than that of the binary foaming agent,and the ISFCQI of the binary foaming agent is greater than that of the unitary foaming agent.The ISFCQI of foaming agent shows positive correlation with foam flooding recovery. |
