该文用实验方法研究了声场提高原油采收率的机理。研究表明：声场对解除油层伤害造成的固体堵塞、消除贾敏效应及改善孔隙附面层均有一定作用。由于油层解堵，提高了水驱油波及系数及原油采收率。在所给实验条件下，经声场处理的含油岩心，水驱油采收率可提高６％～１７％。现场应用例子也取得了良好效果。
In this paper, the mechanism of sound field enhancing oil recovery is studied experimentally. The results show that the sound field plays a role in relieving the solid blockage caused by oil layer damage, eliminating the Jia-Min effect and improving the pore-surface attachments. As a result of reservoir plugging, water flooding has been enhanced both in terms of coefficient and oil recovery. Under the given experimental conditions, oil-bearing oil cores treated by sound field can increase oil recovery by 6% -17%. Field application examples have also achieved good results.
