Abstract
Polymer flooding is a vital method for the enhanced oil recovery of heterogeneous formations after water flooding. However, few visualization approaches are available to conduct the online monitoring and the non-invasive evaluation of polymer flooding experiments in natural rock cores. In this study, online dynamic magnetic resonance imaging (MRI) and T2 distribution measurements were employed to monitor polymer flooding in a natural layered core using low-field MRI equipment. A modified spin echo (SE) imaging technique featuring half Fourier acquisition and a short echo time (3.5 ms) was used to achieve dynamic MRI images during flooding with a temporal resolution of 93 s. Moreover, online T2 distribution measurements by the Carr-Purcell-Meiboom-Gill (CPMG) pulse sequence were utilized to estimate the bulk remaining oil saturation to validate the MRI results. Furthermore, the spatial distribution of the displacement efficiency was obtained through MRI signal processing and was visualized via a pseudo-colour mapping technique. A statistical analysis was carried out to estimate the change in the mean of the spatial distribution of the displacement efficiency. The results show that an improvement in the oil recovery from the natural layered core by polymer flooding after water flooding can be intuitively observed by the proposed method. Our low-field MRI methods provide quantitative and revealing information that can be beneficial for flooding mechanism studies of enhanced oil recovery.
