  • OW Hydraulic pump manufactured by OILWELL HYDRAULICS INC.
  • Fig. 1 This is the design of the Hydraulic Pump BCL-1, which consists of 19 parts, the same as shown in the figure in section.
  • LOWER RETAINER (BOTTOM RETAINER CLAW): It is the lower part of the pump, in its exterior the seals are housed, in the outer upper end it is connected by a thread of 14 threads per inch with the extension tube, in the part Outer bottom has been milled tangential flat surfaces opposite each other in order to use suitable tools to avoid surface damage by manipulation.
  • END ADAPTER This element is a metal ring (bronze) that retains and aligns the seals, these have "V" channels that maintain the outer and inner shape of the seal, the diameters of these must be smaller than the seals to allow a packing between the jacket and the pump.
  • VITON SEALS (CHEVRON PACKING): These are elements that by their design behave like pressure retainers.
  • CENTRALIZER This element is a bronze ring, with a groove in the center in the radial direction, serves to centralize and reverse the direction of the seal, it is intended to package the seals with the shirt on the sides.
  • EXTENSION TUBE (CLAW EXTENSION TUBE): This is a part of the pump that has different diameters both outside and inside, only serves to extend the length and adapt from a smaller diameter to a larger one, has threads of 14 threads per inch that are assembled by the one end with the discharge body and on the other with the final retainer, geometrically they are two cylinders coupled with different diameters, in the larger diameter two flat surfaces perimetrically opposed have been tangentially milled in order to use suitable tools to avoid superficial damage by manipulation.
  • DISCHARGE BODY CLAW This is a complex element of the Jet Claw pump, through the inner part in an axial and eccentric direction there are eight holes distributed in two parts, through the lower part the formation fluid passes through the upper inner part passes the mixture of injection and formation (production) fluids by discharging through a transverse hole towards the outside thereof. In the upper end it is assembled with adjustment by means of a square thread of 14 threads per inch with the diffuser. On the bottom and through a thread of 14 threads per inch is assembled with an extension.
  • SEALS O-RING: They are elements in the form of a ring, the same that fulfill the function of sealing between two metal parts.
  • DIFFUSER (DIFUSSER CLAW): It is the largest conical part of the pump, which is the continuation of the throat taper, allows the discharge pressure to increase as the diameter increases and at the same time decreases The speed of the fluid, at the end of greater diameter the discharge body is assembled under pressure, and to seal the two elements a seal is placed on the upper part and another on the lower end, the axially seal is metal metal with throat.
  • SEALS O-RING: They are elements in the form of a ring, the same that fulfill the function of sealing between two metal parts.
  • SEALS O-RING: They are elements in the form of a ring, the same that fulfill the function of sealing between two metal parts.
  • THROAT CLAW HOUSE Geometrically it is a cylinder, it is the throat housing, this makes the diffuser, the throat and the nozzle align, internally it has a difference in diameters, the largest diameter accommodates the upper part of the diffuser, the seal between them is obtained by using two seals located in two channels that are at the inner ends.
  • SEALS O-RING: They are elements in the form of a ring, the same that fulfill the function of sealing between two metal parts.
  • THROAT CLAW It is the element of the pump where the two fluids are mixed (injection + production) and the energies are changed from kinetic to potential, its external shape is two cylinders coupled with two different diameters; the nozzle retainer (nozzle retainer) is housed in the upper part of the smaller diameter cylinder, at the other end it is assembled with the diffuser in an axial direction, the interior is formed by two geometric figures, in the upper part (inlet) It has the shape of a cone and its sides are convex, then a cylinder is formed in which the distance of the throat varies from 2 to 3 times its diameter, at the end of it, it starts a cone that ends at the beginning of the diffuser, the material used is tungsten carbide, which is resistant to abrasion wear.
  • NOZZLE RETAINER CLAW RETAINER It is the part of the pump where the nozzle is housed or centered, has five holes in its perimeter where the formation fluid passes, it is housed over the throat . The most important function is that it maintains the distance of the mouthpiece with the throat.
  • NOZZLE CLAW This is a conical shaped body of revolution, externally it is visualized in a single body that forms two geometric figures, the one is a cylinder and the other a cylindrical truncated cone, formed by a symmetrical concave curvature , inside its shape is a funnel with a mirror-like finish that prevents pressure drops.
  • SEALS (O-RING) They are elements in the form of a ring, the same that fulfill the function of sealing between two metal parts.
  • EXTERNAL TUBE (OUTER TUBE CLAW): It is a cylinder that is subjected to external and internal pressures. In its two threaded ends (square thread 8 threads per inch) the discharge body is connected and in the other the nozzle housing, through the inside the formation fluid passes until it has contact with the nozzle, nozzle has on the outside contact with discharge pressure.
  • NOZZLE HOUSING HOUSING This element carries the seals on the outside, houses the nozzle inside, it is assembled at the top with the fishing neck and seal housing by means of a thread of 14 threads per inch and on the underside with the outer tube, using a square thread of 8 threads per inch, this makes it more versatile for assembly.
  • FISHING NECK It is one of the important parts used to recover the pump from the bottom of the well with the help of a wire line, the maximum diameter is used to hang with the rest of the pump in the housing It also stops the seals by adjusting a thread of 14 threads per inch with the nozzle housing.
  • Fig. 2 This is the design of the fishing neck in shape and measure.
  • Fig. 3 This is the design of the fishing neck that allows a filter to be placed.
  • Fig. 4 These are the holes in the fishing neck in shape and number.

Abstract

L'invention concerne l'extraction de pétrole du sous-sol, sur la base du principe de Venturi et au moyen d'un fluide moteur (notamment du pétrole ou de l'eau injectés à haute pression) et comprenant 19 parties statiques. Le problème des pompes existantes sur le marché réside dans le fait que : elles s'usent beaucoup, ce qui provoque des pertes de pression par friction ; elles présentent de nombreuses parties et corps métalliques rendant difficile l'entretien ; leur conception rend difficile leur récupération dans des puits déviés ; elles nécessitent une quantité supplémentaire d'énergie de surface. L'invention concerne plus particulièrement une pompe à jet ayant subit des modifications au niveau du col de repêchage du logement de l'embout, du tube extérieur, du corps de décharge, de l'adaptateur d'extension et de l'obturateur inférieur. Ladite pompe à jet de l'invention résout les problèmes se rapportant aux pompes existantes, procurant une plus grande versatilité pour insérer des jauges de mémoire et restaurer la pression des puits tout en minimisant la durée de l'opération.
