Gas condensate fields are kinds of exceptive and complicated gas field; they assume key economic value because they both produce natural gas and condensate oil; the appearance of retrograde condensation because of the declining of the formation pressure during the development of those fields can make the development of this fields difficult , and because of it ,it is difficulty to improve the percent recovery of condensate oil.
凝析气田是一类极为特殊而复杂的气田；一方面由于能同时采出天然气和凝析油而具有重要的经济价值；另一方面，在开发过程中由于地层压力的降低会出现反凝析的现象，从而影响气藏的最终采收率。

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。
