基于核磁共振技术对三元复合驱乳状液运移规律研究

Study on Emulsion Migration Rule in ASP Flooding Based on NMRI Technology

通过核磁共振成像技术对三元复合驱(ASP驱)驱油过程的微观机理进行描述,再通过对原油及ASP驱体系的流变性的实验的基础上,描述出ASP体系在多孔介质中的运移情况。最后通过对ASP体系乳状液建立合适的运移数学模型,发现实验数据与模型结果基本符合,表示所建立的运移数学模型具有合理性。

The micro mechanism of the flooding process of ASP flooding was described by NMRI, and the migration of the ASP system in the porous medium was described on the basis of the experiment of the rheological properties of the crude oil and the ASP flooding system. Finally,a suitable mathematical model for the ASP emulsion was established, and it＇s found that the experimental data were basically consistent with the model results, indicating that the established mathematical model of the seepage flow is reasonable.
