The invention comprises that:(1) an injectant containing air is formed and the injectant is injected into a manto (3) through an injection well (2) or a recovery well (1);(2) the pressure of the injection well (2) and the recovery well is kept (1) for a period of time so that the oil and the injectant are mixed into more uniform fluid;(3) the pressure of the injection well (2) and the recovery well (1) is decreased, the pressure of the manto(3) is decreased and the oil-containing mixed fluid is obtained from the recovery well (1) or the injection well (2);(4) the procedure of (1),(2) and (3) is repeated, the pressure fluctuation of the fluid in the manto (3) is realized until the oil recovery rate is less than the economic recovery rate.

本发明包括：①形成包含气体的注入剂，将注入剂通过注入井(2)或采收井(1)注入矿层(3)；②保持注入井(2)和采收井(1)的压力一段时间，使油分和注入剂混合形成比较均匀的流体；③然后降低注入井(2)和采收井(1)的压力，降低矿层(3)压力，并在采收井(1)或者注入井(2)获取含油混合流体；④不断重复步骤①②③，实现矿层(3)中流体的压力波动，直到石油的采收率低于经济开采率为止。
