Solution
Polymer flooding technology is a crucial measure for sustaining high and stable oil production in China’s oilfields. It achieves efficient oil displacement through dual mechanisms: macroscopically expanding sweep efficiency and microscopically recovering residual oil. High-molecular-weight polymers exhibit excellent water solubility and injectivity, along with strong resistance to shearing, high salinity, and salt. They possess outstanding chemical and biological stability. Our company has developed specialized flooding product series for both conventional and low-permeability reservoirs. Additionally, these high-molecular-weight polymers demonstrate selectivity toward oil and water, preferentially entering high-water-cut layers. By adjusting the water absorption profile within the formation and blocking high-permeability water channels, they effectively reduce water production while enhancing oil recovery, making them ideal for deep profile control and water shutoff.
