Daqing Oilfield Co., Ltd. passed the oil field test in Zone A of the company area on the three types of oil layers with effective thickness less than 0.5m and permeability less than 0.050 μ m 2 . After the company’s oil production area in Block A has been injected for more than 6 years, it has been found that the method has achieved good oil and precipitation effects. This paper analyzes the dynamic characteristics of injection wells and production wells after injection, and compares with the first and second types of oil layers, and summarizes the variation rules of low-segregation driving states of the three types of oil layers, which is important for guiding the development of the three types of oil layers in the future. significance.
