Experiment Study on Oil Displacement Efficiency of Oil Sands under Fluctuation -Chemical Compound Conditions

摘要

Oil displacement efficiency of oil sands can be improved by low-frequency resonant wave combined with chemical displacement agent. By the experiment of oil displacement effect of the compound oil displacement agent, we select the agent that is most suitable for a certain oilfield. On the basis, to link the vibration principle of low-frequency resonant wave, we investigate the influence of resonant wave on oil displacement effect. The results indicate that the oil displacement effect of recombination action is better than chemical method alone.
