Definitions

  • the present invention relates to a device for placing a tool or instrument in a pipe and recovering it by circulation of a carrier fluid, usable in particular for the operation at the bottom of wells of autonomous hydraulic pumps, in production from inside 'a production tube.
  • the invention particularly relates to the installation and removal of autonomous tools at the bottom of oil or water producing wells.
  • This technique is particularly advantageous in the case of autonomous downhole hydraulic pumps, in particular of the jet pump type, when the production is brought to the surface by a production tube (tubing).
  • a production tube tubing
  • This is the example that was used here to describe the invention, but it also applies to all the equipment which can be useful for checks, regulations, measurements and safety at the bottom of the well, in particular pressure recorders, temperature, or flow rate which can be exploited in this way, alone or associated with autonomous pumps.
  • the invention also applies to gas producing wells as well as wells activated by gas-lift.
  • the hydraulic bottom pumping assemblies and in particular the jet pumps are relatively compact. Their weight and size are reduced enough to generally allow their installation and their movement inside a production tube. These pumps are most often simply placed on a receptacle from which they can easily be detached. They can then be considered free, because they can be quickly installed or removed from the well by hydraulic circulation or by cable work. Compared to other non-free activation systems - (rod pumps, conventional electric pumps), their maintenance is therefore simpler, faster and less expensive.
  • the most commonly used technique consists in supplying the free hydraulic pumps with a working fluid injected into the production tube. The production is then reassembled through the annular space between this production tube and the casing. In some cases, production can be escalated by another production tube, with double completion.
  • the driving pressure in the production tube makes it possible to apply and maintain the pump in its housing at the bottom of the well.
  • To reassemble the pump the circulation of fluids is reversed.
  • a valve placed at the discharge of the pump keeps downstream the pressure necessary for its displacement.
  • the geometry of the annular space is not well defined, the production tube being positioned irregularly. This does not allow easy calculation of the flows of the fluids produced; deposits are favored in areas with low flow velocities, in particular at the points of contact between the production tube and the casing.
  • the present invention eliminates these drawbacks by allowing production through the production tube.
  • the working fluid which is preferably a fluid suitably treated to prevent the risks of corrosion, abrasion and deposits, is injected into the annular space.
  • the pumped fluid mixed with the working fluid is brought up to the surface by the interior of the production tube where the phenomena of corrosion, erosion and deposits can be more easily controlled and treated.
  • the main object of the present invention is a device for placing a tool or an instrument in a pipe and recovering it. It can be used, in particular, to stimulate the production of an oil well by allowing the installation at the bottom of the well of an autonomous hydraulic pump.
  • This pump can allow production from inside a production tube.
  • the present invention provides a device of small dimensions of simpler implementation, and above all of greater reliability, which allows in particular to obtain a significant reduction in manufacturing and production costs.
  • the device according to the invention makes it possible to set up a tool or an instrument in a determined working position inside a pipe, then to recover it by circulation of a vector fluid, it comprises an element tubular adaptable to the tool or instrument and an annular seal.
  • said tubular element contains means for selecting the direction of movement of the tool or instrument which, in combination, comprises shutter means comprising a shutter cooperating with a conjugate part and a device for selecting the direction of displacement, said conjugate part comprising at least one sealing surface, said closure means having at least three states, in the first state, said shutter cooperating with said conjugate part to let the fluid pass in a first direction, in the second state, said shutter cooperating with said conjugate piece preventing the passage of the fluid in the direction opposite to said first direction, in the third state, said shutter cooperating with said conjugate piece preventing the passage of fluid in said first direction, said device selection being adapted to assign the shutter means either to said first two states excluding the third e, or in said third state
  • the conjugate part may include at least one other sealing surface and said sealing means may have at least three positions, the first position corresponding to said first state, the second position corresponding to said second state where said shutter cooperates with said surface, the third position corresponding to said third state where said shutter cooperates with said other surface.
  • the device may include means for remote control of said reversing device.
  • the remote control means may include elastic and / or plastic means adapted to allow the displacement of said shutter relative to said conjugate part only from a force of predetermined intensity.
  • the device may include pumping means capable of acting on said device.
  • Said reversing device can be adapted to assign to the shutter means, either said first two states excluding the third, or said third state preventing the return to said first two states.
  • the device may include a locking device and said tubular element may actuate the engagement and / or disengagement of said locking device from the tubular element, tool or instrument assembly in said pipe.
  • Said device for reversing the direction of movement may form an integral part either of said shutter or of said conjugate part.
  • the shutter means may comprise in combination a shutter such as a ball and a member for reversing the direction of movement, this member being hollow and having an orifice separating the external and internal walls which form said sealing surfaces for said shutter element. , said member being able to move axially in said tubular element under the effect of an overpressure, against the action of return means from said second position, where said orifice is closed by said shutter, to said third position where the diameter of said orifice is increased and allows the passage of said shutter element.
  • Said member may include a set of coaxial strips which, by moving away from one another, make it possible to increase the diameter of said orifice.
  • the internal wall of said tubular element may include a bearing inclined on the axis of said tubular element against which said member bears at its upper part under the action of said return means.
  • An annular element or pusher may be interposed between said member and said elastic return means, this pusher being connected to said tubular element by at least one safety element such as a shear pin.
  • a jet pump that can be installed in a pipe equipping a well, the production of which is activated by injecting a working fluid from the surface into the annular space between the pipe and the wall of the well, may be equipped with a device such as defined above allowing from the surface the installation of this pump in the working position in the pipe and its recovery on the surface.
  • the invention has in particular enabled the development of an autonomous hydraulic pumping assembly, the installation and removal of which takes place by simple reversal of the circulation of fluid.
  • This assembly can be moved in any direction inside the production tube with a speed of the order of one meter per second.
  • the operation of production can be carried out in less than an hour.
  • its position can be perfectly determined at any time, knowing the flow rate of injected fluid necessary for its movement. No additional equipment compared to the mode of production by the annular space is necessary on the surface to carry out these operations.
  • the reference 1 designates a producing geological formation in which a well 2 has been drilled.
  • This well is fitted with a casing 3 comprising perforations 4 at the level of the producing layer.
  • the production is activated by a jet pump designated as a whole by the reference 5.
  • This pump is installed freely in the production tube 6 disposed inside the casing 3.
  • free pump is meant here a pump which can be move in the production tube 6 and which, in operation, rests on a shoulder 7a formed in the receiver tube 7, integral with the production tube 6.
  • a sealing device 8 of the packer type surrounding the receiving tube 7 isolates the deposit from the annular space 9 comprised between the production tube 6 and the casing 3.
  • the jet pump 5 essentially comprises a nozzle 10 surmounted by a mixer 11 and diffuser 12 assembly.
  • the production is activated by injecting a motor fluid at the surface at 13 into the annular space 9.
  • This fluid enters the nozzle 10 by means of lateral orifices 14 formed in the receiving tube 7 - (the flow of this fluid is represented by the arrows in solid line).
  • the restriction of the cross-section of passage of the working fluid through the nozzle 10 forms a jet at high speed.
  • This jet causes a vacuum which makes it possible to suck the fluid to be pumped at the base of the tube 7 and to draw it through the neck 15.
  • the flow of the fluid to be pumped is shown in dashes.
  • the two fluids meet in the mixer 11.
  • the diffuser 12 makes it possible to transform the kinetic energy acquired by the fluids into pressure.
  • the pressure gain thus obtained makes it possible to bring the power necessary to raise production up to 16 to the surface.
  • a bottom valve 1 7 disposed under the jet pump 5 prevents the return of the pumped fluid to the deposit.
  • FIG. 2 shows the entire pump 5 with the original installation and removal mechanism according to the invention.
  • This mechanism is articulated around selection means such as a selective valve 18 allowing the selection of the direction of movement of the pump in the tubes 6 and 7, this selective valve being housed in the tubular element 19 integral with the pump 5.
  • the selective valve 18 consists of a ball 20 or other obturator element, retained between a sealing surface 21 a placed on the mating piece and a high stop 22. The position of the shutter relative to the mating piece allows or prevents the circulation of the fluid through the pump 5.
  • the conjugate part for reversing the direction of movement 21 comprises several contiguous parts or lamellae 23 arranged in a corolla which form, as shown in FIG. 3, a hollow coaxial assembly 24 held in place by a pusher 25 against a conical bearing 26 or more generally a bearing inclined on the axis of the tubular element 19; this pusher is supported on a spring 27.
  • One (or more) safety element 28 ensures the reliability of the assembly by preventing accidental opening of the system.
  • An annular seal 29 placed above the valve completes the assembly.
  • the role of the selective valve system is to transform the pressure available in the production tube 6 into a force acting on the pump 5 in order to cause it to move during the installation and removal operations, while leaving free passage to the fluid, during of the pumping phase of the production fluid illustrated in FIG. 2.
  • the ball 20 is placed in the position indicated in FIG. 2A.
  • the ball 20 cannot pass through the upper orifice 21 of this member whose passage section is insufficient.
  • the walls of the parts or lamellae 23 are arranged to form an external sealing surface 21 a and an internal sealing surface 21 b respectively for the ball 20 in this position of approximation of the parts or strips 23.
  • the strips cannot move away from each other, since they are kept in contact with the conical bearing 26 by the spring 27 and the safety element 28.
  • pressurized fluid at 16 into the production tube creates a pressure which exerts a downward vertical force on the pump 5, the fluid being unable to circulate through the latter. This effort is sufficient to drive the pump 5 to its anchoring position.
  • the pump is locked by blocking "dogs" 30 (Fig. 2), integral with sliding sleeves 31, in the corresponding recesses 32 of the tube when the autonomous assembly: tubular element, tool or instrument has been positioned by a location module such as a stop or a key device well known in this art.
  • the differential pressures can be for example 20 bar for the descent of the pump and 40 bar for its locking.
  • the circulation of fluid is reversed, i.e. the pressurized fluid is injected into the production tube from the surface.
  • the bitt 20 returns to the sealing surface 21a.
  • a relatively high overpressure 80 bar for example
  • the force compresses the spring 27, the conjugate part for reversing the direction of movement is pushed down, as indicated in FIG. 28.
  • the lamellae 23 making up the sealing surface 21a move apart allowing the ball to pass 20 which is housed in its new housing 33 (Fig. 2B) inside the mating piece. Stopping the injection balances the pressures in the production tube, eliminating the force acting on the selective valve 18: the spring 27 then returns to its initial position and the ball 20 is poisoned in the housing 33 (Fig. 2C ).
  • FIG. 4 shows the detail of a second device for selecting the direction of movement according to the invention which is housed in the tubular element 19 secured to the pump 5 as in the previous description of FIG. 2.
  • the means for selecting the direction of movement are composed of a shutter 20 which can be moved axially by means of a stop guide 35 from a position defined by the stop guide 35 to a position where the shutter 20 is in contact with the surface d seal 21a of the conjugate part.
  • the conjugate part 21 is formed of contiguous lamellae 23 arranged in a corolla and all connected to their base, as shown in FIG. 4A.
  • the lamellae 23 have an elasticity such that they allow the passage of the shutter 20 only from a certain hydraulic overpressure exerted on this shutter.
  • the shutter 20 is placed opposite the surface 21 b, being unable to resume its position anterior. This can be achieved, in particular, by making spans 20b and 21 substantially perpendicular to the direction of movement of the shutter as shown in FIG. 4.
  • the shutter 20 comes to bear against the surface 21a a to ensure the seal and allow the descent of the tubular element and tool or instrument assembly under the action of the pumping means which produce an axial force descending on the assembly .
  • the locking is then carried out as previously indicated in the description of FIG. 2A.
  • the inversion of the direction of circulation of the fluid allows the shutter to rest on the sealing surface 21 a. Due to a relatively large overpressure applied to the shutter, it flares the conjugate part 21 and / or shears the security element and penetrates inside while being trapped there. A retaining device 37 prevents the shutter from lowering further.
  • the shutter After reversing the circulation of the fluid (injection through the annular space), the shutter is applied against the sealing surface 21b, blocking the passage of the fluid.
  • the increase in pressure in the pump 5 establishes an upward force which allows the unlocking of the pump and its ascent in the production tube.
  • the sealing surface 21b has a shape such that when the shutter 20 is applied thereto by exerting an axial force directed towards the upper part of FIG. 4, the strips 23 do not move apart.
  • FIG. 5 shows a detail of a third embodiment of the means for selecting the direction of movement according to the invention which is housed in the tubular element 19 integral with the pump 5 as in the previous description of the first device mentioned.
  • the means for selecting the direction of movement are composed of a shutter 20 which can be moved axially by means of a stop guide 35 from a position defined by the stroke limiter 37 to a position where the shutter 20 is in contact with the surface d seal 21a of the conjugate part.
  • the conjugate part 21 comprises two surfaces 21 a and 21 b which can make contact with the shutter to seal.
  • the shutter 20 is composed of radial strips 36 connected at their center and integral with the axis 38. Their thickness, width and length are adjusted to provide the elasticity necessary to allow the shutter 20 to pass through the conjugate part 21 under the effect of a predetermined overpressure applied when the shutter presses against the surface 21 a.
  • the injection of the pressurized fluid at 16 into the production tube creates a pressure which exerts a vertical downward force on the pump 5, the fluid being unable to circulate through the latter because the shutter 20 is in contact with the surface 21 has and seals.
  • the assembly is locked as described in the first device mentioned.
  • the stopping of production allows the shutter to rest again on the sealing surface 21a.
  • the lamellae 36 of the shutter deform and allow the passage of the shutter through the mating piece.
  • the surface 21a is the only surface to seal, on the one hand, during the injection of fluid by the production tube for the descent of the pump, and on the other hand, during the injection of fluid through the annular space for removal of the pump.
  • the dogs are actuated while the shutter 20 is in abutment on the sealing surface 21 a. They maintain the shutter 20 substantially in this position. Sufficient pressurization of the annular space 9 then causes the removal of the pump. Thus, the surface 21 b would become unused and could be deleted.
  • the tubular element comprises several parts connected to each other by at least one articulation.
