摘要： 考察了CO2/驱油剂的表面张力及粘弹模量,分析其产生泡沫的能力;考察了CO2/驱油剂泡沫体系的半衰期及携液量,分析其产生泡沫的稳定性;最后通过双平行管驱油实验,分析CO2/驱油剂泡沫体系改善非均值储层开发效果的作用。结果表明,CO2/驱油剂弱泡沫体系虽然稳定性不如N2/泡沫剂体系,但其在驱替中产生的调剖作用仍大幅度提高了采收率。

关键词: CO2 , 驱油剂 , 弱泡沫体系 , 稠油热采

Abstract: In the heavy oil thermal recovery of Shengli oilfield,the carbon dioxide technology enhanced oil recovery and oil displacing agent technology enhanced oil recovery has been widely used.Implementation of the results statistics show that synergistic effects of two technology is far better than asingle technology.Analysised that the weak foam system generated by the two technology played a important role in blocking large pore,resulting in improved thermal efficiency,improved development results.Laboratory studies of weak foam syste minterface characteristics of gas-liquid,foam stability,and non
-mean reservoir flooding effects,experimental results show that weak foam system in the heavy oil thermal recovery profile important role in blocking.

Key words: CO2 , Oil displacing agent , Weak foam system , Heavy oil thermal recovery
