Abstract:In order to compare the oil repellent effect of microemulsion drive and water drive, the remarkable effect of improving recovery rate of microemulsion drive is proved from the microemulsion aspect by analyzing the crack core oil drive experiment and the distribution law of the residual oil in the pore. The experimental results show that the yield rate of microemulsion drive can increase by 10.8% compared with the water drive, and the final recovery rate is as high as 49.7%, which shows that the recovery rate o… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
