基于微流控模型的自发吸吮采油过程实验研究

摘要

Considering the micro level simulation that microfluidic device could provide and the character of porous medium in reservoir,this experiment made the use of microfluidic device to simulate spontaneous imbibition process,which is the main oil displacing mechanism in fractured reservoir to get the relationship between the distance of displacing front and time,the velocity of displacing front and time,finally,it makes us to have a further understanding of spontaneous imbibition.%考虑到微流控技术能够实现微米级别的微观模拟以及原油储层微观孔隙介质的特性，利用微流控模型模拟常见于裂缝性油藏中的自发吸吮采油过程。研究结果表明，在自发吸吮过程中，驱替前缘的移动距离与时间呈三次方关系、驱替速度与时间呈平方关系，使得自发吸吮过程能够被更深刻地了解。
