である。The Wagner device disclosed in the above-referenced patent application is a significant improvement over conventional steam generators. However, there was still considerable room for further improvement in Wagner's device. In the Wagner type steam generator, the steam generator is lowered into the borehole to the level of the formation to be treated, at which point steam is generated and the steam is injected into the formation. be. After a predetermined period of time, the steam generator is withdrawn from the borehole and the pump is lowered in its place to collect the oil extracted by the steam. In this case,
A significant amount of time is required to lower and withdraw the equipment, and the steam-treated formation therefore cools during that time. Therefore, most of the effects of steam treatment end up being a waste of effort. Moreover, the operations of lowering the steam generator into the borehole, then removing it and lowering the pump require a great deal of effort and relay time, and therefore require a great deal of expense. be.

可能である。As shown, the pump inlet 36 is located proximate the steam nozzle 30. Such a configuration is suitable for steam generation 11
This is suitable when operating the pump 6 and the pump 32 sequentially. In such an arrangement, oil is pumped out of the borehole 4 by the pressure generated by the steam, and therefore the pump is not operated simultaneously while the steam generator is operated. However, it is possible to operate the pump 32 while the steam generator 16 is stopped. Therefore, it is possible to start oil production while the formation 10 is at its maximum temperature and the oil viscosity is at its lowest. Therefore, it is possible to pump and recover a significant amount of oil in the time it would take to move the conventional equipment. Furthermore, in the present invention, since there is no need to move the equipment, it is possible to operate the steam generator 16 and the pump 32 alternately, for example, the pump can be operated for 4 hours after steaming for 4 hours. It is possible to perform alternating operations.

The pump inlet conduit 38 is elongated in order to maintain the pump inlet conduit 38 at a considerable distance from zero. In such a configuration,
Oil removed from formation 10 by steaming is discharged into borehole 4 adjacent pump inlet 36, so that steam generator 16 and pump 32 can be operated simultaneously. With such a configuration, it is possible to extract oil from extremely difficult geological formations that would be impossible using conventional methods.
