Definitions

  • the invention relates to a device for conveying flowable materials from a production well according to the preamble of claim 1.
  • the object on which the invention is based is to simplify a device of the type mentioned in the introduction and thereby to increase its reliability in the extreme underground conditions of use.
  • the design of the rotors and stators of the drive and pump for the same eccentricity creates a matching path of movement of the rotors, which radially decouples the connection of the rotors from one another, for. B. can be dispensed with by universal joints and thus enables the rotors to be connected directly to one another. Such a device reduces the risk of failure due to the saving of parts mounted against one another and thus creates the conditions for longer, maintenance-free operation.
  • the device conveys a substantially higher amount of flowable substances from the production bore than pressure medium has to be pressed into the same.
  • the differential pressure across the displacement rotary machines which is in inverse proportion to the working chamber volumes, is coped with by the drive through multi-stage training. As a result, the share of the total differential pressure reduced per stage can be kept low and the sealing edges between the working chambers can be protected from leakage or blowing through.
  • the increase in the working chamber volume of the ⁇ pump can be achieved by a higher gradient of the helix of the rotor and stator, by a larger working chamber cross-sectional area or by a combination of both measures. Appropriate selection and coordination of both measures makes it possible to create a desired working chamber volume even with a small borehole diameter.
  • the number of stages S A of the drive, the number of stages Sp of the pump, the working volume Vp of the pump, the working chamber volume V A of the drive and the overall efficiencies TJGA 'TJGP of the drive and pump correspond to the formula the same load on the sealing edges between adjacent working chambers is achieved taking into account the losses occurring during operation of the drive and pump.
  • the line required in this configuration, parallel to the working chamber of the pump or drive, can preferably be formed by an intermediate space between the coiled stator or rotor sleeve and an associated carrier sleeve, whereby the space already available can be used and an enlargement of the housing diameter can be avoided.
  • a particularly compact embodiment enables a device in which the stators of the pump and drive are designed as external and internal stators and the rotors are formed by a common body arranged between the stators.
  • the pressure medium is preferably passed through a pressure medium line in the form of a usual drill pipe embedded in the bore, so that the larger cross-section of the annular space between the flow pipe than the drill pipe as the delivery pipe for the flowable substances and the lining of the hole is available.
  • a pressure medium line in the form of a usual drill pipe embedded in the bore, so that the larger cross-section of the annular space between the flow pipe than the drill pipe as the delivery pipe for the flowable substances and the lining of the hole is available.
  • the pressure medium is fed to the drive through the annular space between the drill pipe and the borehole lining and the flowable materials are conveyed through the drill pipe, a drill pipe with a particularly large diameter then being used.
  • the device shown in FIG. 1 comprises an above-ground pressure medium source 1, which pressurizes a pressure medium 29 through a pressure medium line 3 arranged in a production bore 2
  • a pressure medium line 3 arranged in a production bore 2
  • Form of a drill pipe 32 leads to the bottom of the bore.
  • the pressure medium is supplied to an arrangement, designated as a whole by 4, which is accommodated in a common housing 7 and comprises a drive 5 and a pump 6.
  • the arrangement 4 can also be arranged in another area of the bore 2, in addition to the sole area, at which flowable substances 8 penetrate from a deposit into the bore 2 through perforations in the borehole lining 9.
  • the drive 5 consists in particular of a coiled rotor 10, which is accommodated in a coiled stator 11.
  • the stator 11 is in turn surrounded by the housing 7.
  • the pump 6, which, like the drive, comprises a rotor 12 and a stator 13, which in turn is surrounded by the housing 7.
  • the rotor 12 of the pump 6 is rigidly connected to the rotor 10 of the drive 5.
  • the lower end face of the rotor 12 is supported against an axial bearing 14. 1, the rotor 10 and the stator 11 have the same eccentricity as the rotor 12 and the stator 13 so that both rotors 10, 12 perform the same eccentric wobble movement in operation.
  • the drive 5 is provided with twenty times the number of stages of the pump 6.
  • the pressure portion acting on each sealing edge thus corresponds to that of the pump 6, so that both rotary machines are loaded equally.
  • the flowable substances 8 enter the pump through openings 15 and together with the pressure medium 29 through openings 16 into the annular space 34, which serves as a delivery line 33, from.
  • a direct short circuit between the openings 15 and 16 is prevented by a packer 17 which is arranged between the housing 7 and the borehole lining 9.
  • the alternative shown in Fig. 2 comprises a drive 5 and a pump 6 with coils running in the same direction. While the pump 6 is identical to that in Fig. 1, the drive 5 is reversed, i.e. flows through from bottom to top with pressure medium 29. For this purpose, the pressure medium line 3 is guided parallel to the working chambers 18 of the drive 5 and opens into it from below.
  • the same flow direction of drive 5 and pump 6 leads to opposite directions of the axial reaction forces on the rotors 10, 12, so that they can compensate each other and relieve the thrust bearing 14.
  • the pressure medium 29 is supplied to the drive 5 from below.
  • the spatial arrangement of drive 5 and pump 6 in the housing 7 is reversed, as a result of which a seal between the working chambers 18 of the drive 5 and those 19 of the pump 6 can be omitted.
  • FIG. 4 corresponds again to that in FIG. 1 with regard to the arrangement of drive 5 and pump 6, the design of drive 5 and the pressure medium supply also being the same version.
  • the spiral in the pump 6 is carried out in the same direction as in the drive 5, so that the flowable substances 8 flow through the pump 6 from top to bottom and are conveyed upward after a reversal of direction through a line 21 running parallel to the working chamber 19 of the pump 6 .
  • FIGS. 5 and 6 Possible embodiments of such a line 3, 21 are shown in FIGS. 5 and 6 using the example of multilobe displacement machines.
  • the stator 11; 13 housed in the form of a shaped sleeve 22 in the housing 7.
  • the space between the inwardly directed coils of the shaped sleeve 22 and the housing 7 serves here as a line 3, 21 which runs parallel to the working chamber 18, 19.
  • pressure medium 29 or flowable substances 8 flow through the working chambers 18, 19 in a direction pointing into the plane of the drawing, while flowing through the line 21, 3 in a direction pointing out from the drawing.
  • rotor 10, 12 it is also possible to additionally or alternatively to form rotor 10, 12 as a sleeve 31 fixed on a carrier sleeve 30 and to use the space between the outwardly projecting spiral of the sleeve 31 and the carrier sleeve 30 as a line 3, 21 or to make the rotor 10, 12 hollow and the interior space for this Use purpose.
  • drive 5 and pump 6 are interleaved.
  • the drive is formed by the inner stator 11 and the inner region 26 of a common rotor 25.
  • the outer stator 13 and the outer region 27 of the common rotor 25 are assigned to the pump.
  • An axial line 28 is additionally assigned to the axial bearing 14.
  • the pressure medium 29 is supplied to the drive part 5 via the hollow inner stator 11 and flows through the associated working chamber 18.
  • Pressure medium 29 and flowable substances 8 leave the housing 7 via common outlet openings 16. As the illustration shows, a particularly short, compact design can be realized with this alternative.
  • FIG. 8 shows an alternative of the device according to the invention in which the pressure medium 29 is passed through the annular space 34 between the drill pipe 32 and the borehole lining 9 instead of through the drill pipe 32 and the flowable materials 8 are conveyed through the drill pipe 32.
  • the embodiment in FIG. 3 serves as the basis for the arrangement of drive 5 and pump 6, but any other of the embodiments presented can also be used for the quasi-reversed supply of pressure medium 29 and the conveyance of the flowable substances 8.
  • This alternative is required in the case of chemically aggressive flowable materials 8 to protect the borehole lining 9, specifically from the point that a drill pipe 32 can be replaced more easily than the borehole lining 9 in the event of corrosion damage.
