The average yield increase rate could reach 24.8%.Due to the complexity of the technology itself, the technology is still in the stage of experimental research and has not been applied in large-scale industrialization[21]. 3 Conclusion Any kind of oil production technology has certain adaptability and limitation, which requires petroleum engineers to combine closely with other disciplines, such as petroleum geology, reservoir engineering, etc., fully consider various factors, and select the most appropriate method for different conditions to achieve the purpose of EOR
