泡沫复合驱泡沫稳定性及影响因素研究

FOAM STABILITY AND EFFECTING FACTORS OF FOAM COMBINATION FLOODING

利用毛细管粘度计和多功能驱替装置 ,研究了泡沫复合体系组分中不同起泡剂、聚合物、碱、气体对泡沫稳定性的影响规律 ,以及泡沫复合体系驱替过程中 ,不同的气液比、注入速度、岩心渗透率、原油存在 (残余油饱和度 )等条件对泡沫稳定性的影响规律 。

This paper studies the effect of different foam generation agent, polymer, alkali and gas on foam stability in foam combination system and the effect of different gas/liquid ratio, injection rate, core permeability and oil existence (residual oil saturation) on foam stability in the process of foam combination system displacement. It has a conductive significance on the determination of foam combination ingredient and pilot test.
