Definitions
- the invention relates to a turbopump for pumping highly viscous substances, in particular heavy hydrocarbons or petroleum oils, in which a liquid of lower viscosity is mixed with the fluid to be pumped higher viscosity for the purpose of reducing the viscosity of the pumping medium before entering the pump.
- the turbopump comprises a pump with an inlet and an outlet and a turbine which has an inlet and an outlet which are different from those of the pump and which is fastened on the same shaft as the pump.
- a drive fluid with a lower viscosity than that of the fluid, which is miscible with it is fed under pressure to the inlet of the turbine. Part of the partially released drive fluid coming out of the turbine as the solution fluid is mixed in a chamber with the fluid before it enters the pump, thus reducing the viscosity of the mixture.
- the mixture of solution liquid and fluid is drawn in by the pump at the inlet.
- rod pumps with simultaneous supply of a solution liquid, as described in US Pat. No. 4,056,335, also represents a device for extracting heavy petroleum, which reduces the viscosity of the fluid.
- Rod pumps are only to be operated in vertical boreholes and do not allow the pump to be oriented horizontally, which is particularly advantageous when extracting highly viscous petroleum.
- turbopump The disadvantages listed here can be avoided when using a turbopump.
- These pumps are characterized in that the pump is driven by a turbine, which sits on a shaft with the pump.
- the drive fluid in the turbine is wholly or partially mixed with the fluid.
- the document US-A-4 086 030 relates to a turbopump and shows a mixture of the drive fluid emerging from the turbine with the fluid emerging from the pump. Mixing takes place in a Venturi nozzle, the fluid enveloping the drive fluid emerging from a nozzle.
- the disadvantage here is that mixing takes place only after it has left the pump. The viscosity of the mixture is not reduced before it enters the pump.
- GB-A-2 057 058 also admixes the fluid around a central jet of partially relaxed
- a turbopump for conveying highly viscous substances is disclosed in EP-B-0 246 943.
- a partial flow of the drive fluid is fed into the pumped medium before entering the pump chamber with the aim of reducing the viscosity of the mixture to be pumped.
- the mixing of the drive fluid with the fluid is incomplete because of the annular introduction.
- FR-A-2 656 035 also makes use of the introduction of the drive fluid into the fluid, but is particularly suitable for carrying out the pump operation even in a horizontal position.
- a disadvantage is that the highly viscous fluid is first passed around the pump in the housing before the drive fluid is mixed in and the viscosity is reduced.
- This invention relates to the introduction of a low viscosity solution liquid serving as a drive liquid for a turbopump to a high viscosity fluid to be conveyed with the aim of reducing the high viscosity of the fluid, improving the pumpability of the fluid and increasing the yield of conveyed fluid .
- the solution liquid is used first to drive the pump through the turbine mounted on the same shaft, before it is partially discharged completely or as a partial flow to the fluid before it enters the pump.
- Injection channels are through which the solution liquid for generating a swirl is introduced with both a radial and a tangential component.
- the method can be accompanied by a reduction in the borehole diameter. This is all the more remarkable the deeper the borehole is because the ratio of borehole costs to
- the development according to claim 2 increases the swirling of the chamber contents by a counterflow and promotes mixing.
- the mixture is additionally accelerated by the introduction and the drive power can be reduced. In this case, less mixing than in the teaching described in claim 2 is accepted.
- the embodiment according to claim 4 teaches the introduction of the partially relaxed liquid from the chamber walls.
- the development according to claim 5 teaches the introduction of the solution liquid from the center of the chamber against the flow.
- This has the advantage that the bearing housing can be used as an introduction point for the pump and turbine shaft.
- the shaft is usually stored in a liquid-lubricated radial plain bearing. Therefore, the supply of liquid through the bearing housing to the bearing is already available and can be used for injection into the chamber.
- the training according to claim 7 provides the introduction of
- Solvent liquid through a cross hole in the shaft. As the shaft rotates, dynamic introduction takes place. The angular velocity of the shaft at the point of exit is thus superimposed on the directional components of the speed of the emerging beam. The solvent liquid flows over the partially hollow shaft from the face of the shaft to the bore.
- the first mixing by directional introduction can be followed by a second, mechanical mixing with a static mixer or with a dynamic mixer mounted on the shaft before the mixture finally enters the pump. Due to its design, the mechanical mixer represents a flow obstacle in the main flow direction. When flowing around the obstacles, the flow is swirled and further mixing takes place.
- Fig. 1 shows a section through a conventional turbopump
- Fig. 2 shows an embodiment of the invention for injecting the solution liquid into the mixing chamber
- Fig. 3 shows the arrangement of the injection nozzles for generating a swirl
- Fig. 4 shows the mechanical mixer as a module of the turbopump.
- a line (3) opens into the inlet (2) and comes from the outlet (4) of the turbine (5) of a turbopump.
- This machine essentially comprises the turbine (5), which has an outlet (4) and an inlet (6), and a pump (7), with an inlet (8) and an outlet (9), which are on the same shaft (10) how the turbine (5) is attached.
- a more detailed description of this turbopump can be found in EP-B-0 246 943.
- the turbine (5) is driven by a liquid of low viscosity, which is miscible with the fluid to be pumped.
- the drive fluid is fed to the inlet (6) of the turbine (5) via the line (14).
- the other partial flow which is referred to below as the solution liquid, is conducted via the line (3) in front of the inlet (8) of the pump (7) and, shown in FIGS. 2 and 3, via nozzles (20) and injection channels (21 ) directed into the inlet (2) injected.
- the mixture of highly viscous fluid and less viscous solution liquid enters the inlet (8) of the pump (7) via a feed (11).
- a mechanical mixer can additionally mix the mixture in the feed (11) before it enters the pump (7).
- the pump (7) conveys the mixture from the borehole via a line (12) connected to the outlet (9).
- FIG. 2 shows an exemplary arrangement of the injection channels (21) in the area of the inlet (2).
- the injection direction has a component opposite to the delivery direction.
- the nozzles (20) are formed from a drilled channel (21) of small cross-section and fed through the circumferential ring channel (22) into which the partially relaxed solution liquid flows.
- the inlet (2) is introduced into the housing (25), which is provided with the bore (3) at the lower end, at which the bearing housing (15) with the bearing (13) for the pump and turbine shaft (16 ) connects.
- Grooves (22) or (26) are incorporated in the bearing housing (15) and sealed against the housing (25).
- Chamber (11) at the location of the bearing of the shaft (16) there are webs (27) and passage openings (28), behind it is another chamber (29) in which a mechanical mixer could be accommodated, or to which one directly connects the inlet (8) of the pump (7).
- FIG. 3 shows the position of the nozzles. This representation also shows a directional component of the injection in the tangential direction. Through this Arrangement a rotational flow is generated, which has a three-dimensional helical course taking into account the axial component.
- Fig. 4 illustrates the modular structure of the turbopump and indicates a mixer (30) arranged after the point of introduction of the drive fluid and upstream of the inlet (8) of the pump (7).
- the shear stresses caused by the mixer increase the mixing of the mixture.
- the drive fluid is introduced via a bore (33) in the shaft (10).
- the shaft (10) is provided with a blind hole (34) and is applied with solution liquid via the cavity (36).
- Drive fluid into the cavity (36) can occur between the bearing (13) supplied by a bore (35) in the bearing housing (15) and the shaft (10) or through additional bores.
- the invention is intended to enable the development of petroleum deposits with viscous petroleum more economically than the previously used methods and devices.
