    • A non-rigid carrier conveys a pump and/or the steam generator through a bore of the production tubing string to support enhanced oil recovery operations. An annular space separates the production tubing string and a wall of a wellbore intersecting a hydrocarbon-bearing subterranean formation. Using the non-rigid carrier, the steam generator is conveyed into the wellbore and operated to inject hot gases into the formation through the perforations in the casing. Afterwards, the steam generator is conveyed out of the cased wellbore and the pump is conveyed into the cased wellbore and operated to pump hydrocarbons to the surface. For cyclic injection operations, the pump may be retrieved to the surface and the steam generator may be returned into the well. The production tubing string, such as a production tubing, remains in the well while the pump and/or the steam generator are conveyed up and down the cased well. A base installed in the cased well receives either the pump or the steam generator.
    • 非刚性载体通过生产油管柱的孔传送泵和/或蒸汽发生器以支持增强的油回收操作。 环形空间将生产油管柱和与含烃地层相交的井眼的壁分开。 使用非刚性载体,蒸汽发生器被输送到井眼中并操作以通过壳体中的穿孔将热气体注入到地层中。 之后,将蒸汽发生器从套管井筒中输送出来,并将泵输送到套管井筒中,并将烃泵送到表面。 对于循环喷射操作,可以将泵取回到表面,并且蒸汽发生器可以返回到井中。 诸如生产管道的生产油管柱保留在井中,同时泵和/或蒸汽发生器在套管井上上下传送。 安装在套管井中的基座接收泵或蒸汽发生器。
