为了防止出现这种情况，所产出的湿气通常要脱除凝析油，并将干气再注入储层(干气回注)以保持储层压力。
To prevent this, the wet gas that is produced is often stripped of condensate and the dry gas is reinjected into the reservoir (cycling) to maintain reservoir pressure.
建议当地层压力低于露点压力时，采用保持压力循环注气开采，可提高凝析油的回收率。
It is suggested that when formation pressure is lower than dewpoint pressure, circulating gas injection with maintenance of pressure can be used to enhance the recovery ratio of condensate.
针对一富凝析气藏，在有介质和无介质、保持压力和部分保持压力条件下进行了一系列注气实验。
To address this issue, a series of experiments in this paper are performed and compared to quantitatively investigate the revaporization efficiency of retrograde condensate by lean gas injection.
