Optimization of EOR after combined flooding

Abstract

After polymer flooding treatment, the oil recovery can be enhanced through the application of advanced technology. However, in practical applications, excess residues will be generated after polymer flooding treatment. Therefore, in the analysis and treatment of residues, the distribution law of residues after polymer flooding is analyzed, and the recovery process and distribution treatment process are carried out. optimization to achieve enhanced oil recovery after polymer flooding. After the polymer flooding treatment, the high concentration and high molecular weight polymer treatment can improve the recovery rate of crude oil, and on the basis of the polymer flooding treatment, the polymer flooding effect can be improved, which can effectively improve the crude oil recovery rate. recovery and improve the development efficiency of oilfields.
