摘要
微乳液体系具有对油、水的超低界面张力、较强的增溶能力、多相稳定等特点,是国外近年来发展的一种特别适合稠油油藏、高含蜡油藏的新型解堵增产体系。对其在低渗透水锁伤害解除方面的应用进行了实验研究。室内研究表明,微乳液体系针对水锁伤害的解除率可以达到93%以上,现场应用效果显著。
The microemulsion system has the characteristics of low interfacial tension,strong solubilization and multiphase stability.It is a new type of plugging removal and stimulation system developed in recent years,which is especially suitable for heavy oil reservoir and high wax content oil reservoir.An experimental study on the application of the method in the removal of low permeability water locking injury was carried out in this paper.The results show that the dissolution rate of the microemulsion system can reach more than 93%,and in the field of application,the blocking effect is significant.
