摘要
油藏中原油与水乳化后具有调剖作用,一定程度上可提高原油采收率。采用室内实验探讨了影响乳化性能的因素。结果表明:随搅拌速率、搅拌时间增加,乳化增强;含水率增加时,乳化减弱;存在乳化效果较好的温度区间,而水质影响无明显规律性;其中搅拌速率的影响最大。
In reservoir,oil and water have the effect of profile control after emulsifying,which can improve oil recovery to some extent. The method of indoor experiment is employed to investigate factors influencing emulsification performance,and the results show that emulsification performance enhances as the stirring rate and stirring time increase. On the contrary,emulsification performance weakens as the water ratio increase.There is a temperature section with good emulsification performance while the influence of water quality disorders. The stirring rate has the biggest effect among all influencing factors.
