Definitions
- the present invention relates to a device for remote actuation of equipment used in connection with pipes in which a fluid circulates.
- the actuation is carried out by circulation of a fluid flow rate, this being lower than the service flow rates.
- annular piston having two faces and a throttle member comprising a needle nozzle with variable passage section is used.
- One side of this piston is subjected to the pressure forces existing on one side of the throttle member, the other side is subjected to the pressure forces on the other side of the throttle member
- the nozzle is carried by the piston and the needle is fixed relative to a conduit containing the assembly and in which the piston can move to effect the desired actuation.
- the piston includes return means which maintain it in a rest position corresponding to a relatively large cross-section of the throttle member causing a low pressure drop for service flows.
- patent FR-2575793 The prior art can be illustrated by patent FR-2575793.
- this device operates by increasing the speed compared to the service speeds.
- drilling conditions may prohibit such an increase in flow.
- the consecutive increase in pressure losses downstream of the device can cause fracturing in the ground or destabilize the walls of the well, which can jeopardize the safety of the operation.
- Patent FR-2641320 solves the problem of the precision of the threshold flow rate by using a nozzle or a needle carried by the piston, but movable relative to this piston.
- This nozzle or this needle is sensitive to a flow threshold precisely, but the actuation always has the major drawback of being triggered by an increase in flow compared to service rates.
- the present invention makes it possible to solve these two problems by using a needle-needle system or an appropriate equivalent which in particular allows actuation to be triggered by using a flow threshold lower than or equal to the service flows, while providing an activation force. important as necessary for actuation.
- the method which consists in sending a ball or another obturation member, in the fluid circulation pipe.
- This ball falls or is pumped on a piston having a seat.
- the pipe being closed by the ball cooperating with the seat, the pumping can then develop an actuating pressure on the piston without requiring a large flow.
- this method has many disadvantages. Indeed, the operation time can be relatively long depending on the drilling depth, the total closure of the circulation channel requires a complex and delicate system for ejecting the ball after actuation. Failures of such a system can be catastrophic for continued operations.
- the present invention allows control of the actuation at low flow rate without requiring the sending of a ball, and leaves the circulation channel free of any major obstacle which would risk eliminating the possibility of circulating a fluid in the borehole.
- the present invention relates to a device for the remote actuation of equipment by a variation in the flow of a fluid, possibly incompressible, comprising means of coupling between said device and said equipment, an assembly comprising at least two elements cooperating with each other to control the value of the opening of the passage channel of said fluid.
- This device is characterized in that it comprises a control assembly which adjusts said opening value to make it take one or the other of two particular values, in that the remote actuation of the equipment is performed for predetermined flow characteristics when said control assembly adjusts to one of the two particular opening values of said elements, and in that for the same flow conditions actuation is not obtained when said control assembly sets the other opening value of said elements.
- the assembly comprising two elements can be an assembly comprising a nozzle and a needle.
- Said coupling means can comprise one of these elements and the other element can be slidably mounted in the pipe.
- control assembly may include means for blocking the sliding of said element mounted to slide in the pipe which limit said sliding along two stroke lengths, which correspond to said two predetermined opening values.
- the element mounted to slide in the pipe may include a return means, said return means adjusts the value of the opening of the fluid passage channel to a significantly lower value at said predetermined opening values.
- the hydrodynamic force created by the flow of the fluid at the level of said element slidingly mounted in the pipe opposes in particular the force developed by said return means and said hydrodynamic force causes said sliding element sliding to slide from one or the other sliding stroke value
- the device is also characterized in that said element mounted on said coupling means can be slidably mounted with respect to said coupling means and in that this element comprises a return means whose force is opposed to the hydrodynamic force created by the flow of fluid at said element carried by said coupling means.
- Said element carried by the coupling means can be the nozzle and the other element is then the needle.
- the coupling means can be an actuation shaft
- the device control means may include a system of cooperating fingers with a groove of variable depth and the shape of which regulates the sliding stroke of said element mounted to slide in the pipe according to said two particular values.
- the needle may have different straight sections along its length. The cooperation of these straight sections with the nozzle can create a notable variation in the flow regime of the fluid and this variation can be measured from a distance.
- the device can be applied to the actuation of equipment integrated into a drill string.
- An application of said device can be characterized in that the device, by actuating one or more stabilizers with variable geometry or an elbow connector with variable angle, can allow control of the direction of the trajectory of a borehole.

- FIG. 1C shows the principle of the invention according to another mode.
- Figure 2 shows the device, object of the invention, according to a preferred embodiment but not limiting. The representation is made for the case where there is no circulation of fluid in the pipeline.

- the finger is shown in the position it occupies in the case of FIG. 2.
- FIGS. 2B, 2C, 2D and 2E show the straight sections respectively along AB, BC, CD and DE of the groove of the control assembly.
- FIG 3 shows the device according to the same preferred embodiment as that of Figure 2, but the needle has the position it occupies during the circulation of fluid at service rates.
- FIG. 3A represents the groove of the adjustment assembly with the relative position of the finger in the case of FIG. 3.
- FIG. 3B shows in detail a finger 30 in the groove 31.

- Figure 4B shows the device at the start of actuation
- FIG. 4C shows the device at the end of actuation.
- Figures 5, 6 and 7 show the evolution curves of the differential pressure dp measured between upstream and downstream of the assembly controlling the opening of the fluid passage channel, and as a function respectively of the flow variations Q represented by FIGS. 5A, 6A and 7A.
- Figures 5 and 5A relate to the configuration of Figure 3.
- Figures 6 and 6A concern the configuration of Figure 4.
- Figures 7 and 7A relate to the case of movement of the finger in the groove without actuation or without reaching the drilling rate.
- FIG. 8 represents an example of application of the device to a rotary drilling rig.
- FIG. 9 represents an example of application of the device to a drill string used in particular for making azimuth corrections
- the main idea of the invention is based on a device for partially closing off the passage of the flow of fluid flowing in the pipe in which said device is installed.
- This device can be adjusted according to at least two shutter levels: one corresponds to the shutter value allowing the actuation of said equipment, the other to a minimum shutter value, ie in fact the maximum opening of said device which corresponds to fluid circulation conditions which can allow various conventional operations, in particular drilling.
- the actuation is done according to the prior art thanks to the pressure drops created by said obstruction of the circulation channel. This pressure difference being sufficient to act on actuating means, such as a piston, to allow actuation of equipment.
- actuating means are not activated when the shutter value corresponds to the second level of adjustment.
- the level the obturation of the channel can be such that the flow necessary for the creation of the actuation energy is notably lower compared to the service flows.
- the adjustment assembly can be remotely controlled by any known means, in particular by pressure waves in the pipe, by electromagnetic waves, by axial forces on the pipe, by rotation of the pipe or by other means of remote communication with the device.
- Figure 1 schematically shows a partial closure system of the pipe 1, separating the pipe into a downstream part 2, and an upstream part 3 relative to the sealing system.
- Game comprising a nozzle 4 secured to the pipe and a needle 5.
- the needle 5 is carried by an adjustment device 6 and can slide relative to the nozzle 4.
- the control of the adjustment device is done by a set 8.
- This figure shows a control principle involving the circulation of fluid through the closure system.
- Figure 1 shows more particularly the so-called rest position of the closure system when there is no fluid circulation.
- the action of a return means 7 keeps the needle 5 in its position of greatest penetration into the nozzle 4.
- Figure 1A shows the closure system in its position of greatest passage of the fluid.
- the command received by the assembly 8 adjusted the apparatus 6 so that the sliding of the needle 5, from the position illustrated in FIG. 1, has the longest stroke.
- the return means 7 is thwarted by the flow of the fluid at the needle 5, which causes the needle 5 to recede.
- the flow of the fluid represented by the arrows 9 causes only a minimum of loss load between zones 2 and 3 of the pipeline.
- FIG. 1B shows the closure system in the actuation position.
- the command received by the assembly 8 adjusted the apparatus 6 to limit the sliding stroke of the needle 5 so as to have a restriction in the passage of the fluid thanks to the cooperation of the nozzle 4 with the needle 5.
- the pressure drop created between 2 and 3 activates the equipment located upstream of said device.
- Figure 1C shows the same principle of closure system but in the case where the needle 10 is fixed in the pipe and the nozzle 11 slides relative to the needle.
- a return means 7 positions the nozzle at the location shown 13 when there is no flow. The two positions are obtained as a function of the setting of the assembly 8 which acts on a retaining element 12. The nozzle recedes as much as possible under the effect of the circulation when the retaining 12 is retracted, the setting then corresponds to the drilling position . The nozzle sees are limited sliding in position 14 when the retainer 12 is released, the adjustment corresponds to the actuation position It will not depart from the scope of the invention by the use of other closure systems of the circulation channel than the nozzle-needle system shown, in particular in the form of a valve.
- the invention may not include a so-called rest position as shown in FIG. 1, in fact the adjustment system 6 may be able to pass in an indifferent order from the drilling position of FIG. 1A to the actuation position of Figure 1B without having to go through a rest position.
- the shutter system can in particular remain in the position it previously occupied.
- the coupling means between said device and the equipment to be actuated can be hydraulic if the actuation means of the equipment reacts to a pressure. They can be in particular mechanical and in this case a piston cooperates with the shutter assembly by coupling means so as to have a face subjected to the differential pressure created between the parts 2 and 3. This piston can be connected by a equipment drive shaft. The displacement of this piston under the effect of the differential pressure provides the actuation energy necessary to obtain the determined actuation movement.
- the body of the device consists of the assembly of two connectors 15 and 16 according to conventional methods.
- the upper connector 15 contains the actuation shaft 17 which is hollow.
- the direction of flow of the fluid corresponds to the direction of the arrow 18.
- the end of the shaft 17 carries the assembly composed of a nozzle holder 19, a nozzle 20 and a return spring 21. Seals 22 complete assembly.
- a bidirectional valve 50 makes it possible to balance the pressure between the chamber of the spring 21 and the outside.
- the nozzle 20 thus has the form of an annular piston with differential section, the largest section of which is upstream of the flow.
- the lower connector 16 contains a piston 23 to which the needle 24 is secured by means of a spacer 25.
- This spacer 25 is adapted to allow the circulation of the fluid to pass according to the arrows 26.
- the annular piston 23 has seals 27 substantially at each end, a return spring 28 and a section restriction 29.
- At least one finger 30 cooperates with a groove 31 machined in the body of the piston 23.
- This assembly constitutes a non-limiting example of a system for adjusting the stroke of the piston 23 secured to the needle 24.
- FIG. 2A shows a developed view of said groove carried by the piston 23.
- the groove is continuous around the circumference of the external surface of the piston 23. It consists of an integer number of steps.
- the M-shaped trace drawn by the groove connecting points a, b, c, d and e represents a step.
- the arrows 32, 33, 34 and 35 show the direction of movement of the finger 30 in said groove to pass respectively from a to b, from b to c, from c to d and from d to e.
- FIG. 3B shows in detail the retractable finger 30 in its housing in order to be able to follow the altitude of the bottom of the groove.
- adjusting finger was remote-controlled in particular electromagnetically to adjust the sliding of the piston 23 in one of the two positions by cooperating with stops carried by the piston.
- FIG. 3 represents the device in the drilling position where it is possible to circulate at all flow rates up to the maximum without actuation, at least as long as the pressure drop between parts 2 and 3 remains lower than the differential actuation pressure
- the circulation flow along arrow 18 creates a hydrodynamic force on the needle 24 and piston 23 assembly. This force is adjusted as a function of the passage restriction 29 located in the piston. When said force is greater than the force exerted by the return spring 28, the piston descends until it is stopped by the finger 30 in the groove 31 when the latter is at b.
- Qd the disengagement rate of the needle of the nozzle.
- the finger 30 is maintained at b. This will be the case in drilling with a flow Qf. If on the other hand, it stops circulating, the action of the spring 28 becomes again preponderant, the needle 24 carried by the piston 23 rises in the nozzle and the finger 30 follows the arrow 33 to be located at c.
- the position of the device is identical to FIG. 2 except for the position of the finger 30 in the groove 31.
- Figure 4 shows the device in this position where the finger 30 is at d of Figure 4A.
- the sliding of the needle-piston assembly is shorter due to the position of point d in the groove.
- the pressure drop created in the device is such that the nozzle 20 slides towards the position 36 shown in FIG. 4B.
- the fluid passage channel is even more reduced and for a stabilized flow rate at Qa, the pressure drops increase while carrying out reactivation.
- the actuation will be obtained by the translation of the shaft 17 coupling the nozzle 20 with actuation means.
- This assembly is subjected to the differential pressure created between parts 2 and 3 to slide towards the needle in the position shown 37 in FIG. 4C.
- FIG. 5 represents the evolution of the differential pressure on either side of the device, as a function of time and relative to FIG. 5A which represents the circulation flow regime at the same time.
- FIG. 6 represents the evolution of the differential pressure on either side of the device, as a function of time and relative to FIG. 6A which represents the flow rate regime at the same time.
- the flow is increased to Qd in order to disengage the needle and visualize the pressure drop dp 1.
- the flow is increased to Qa, less than Qf.
- the pressure drop created causes the nozzle 20 to slide.
- the pressure increases by dp2 which corresponds to the actuation of the device by the sliding of the actuation shaft and nozzle assembly.
- the final pressure peak dp3 corresponds to the proximity of the nozzle to the chamfer 39 of the needle. It is not going beyond the scope of this invention if the device is equipped with a remote-controlled locking system for the position of said device. In this case we can make several successive actuations.
- dpi corresponds to the disengagement of the needle
- dp3 corresponds to the end of actuation
- the device may preferably be applied to the remote actuation of equipment intended to control the direction of drilling.
- This equipment is in particular packing stabilizers or elbow fittings.
- FIG. 8 represents the case of a rotary drilling rig.
- the drilling tool 40 is rotated by tubes 41 rising to the surface and composing the drill string.
- Stabilizers 42, 43, 44 are screwed to the lower part of said lining.
- the arrangement can be in particular: the actuating device placed just above the tool 40, the stabilizer 42 above the device, a drill collar 46, another stabilizer 43, another drill collar then a stabilizer 44
- the stabilizers 42 and 43 can be of a variable geometry type as taught in document FR-2641315 and actuated by means coupled to said device of the present invention.
- the actuation can in particular completely retract the blades of said stabilizers 42 and 43.
- the packing has been converted without disassembly maneuver thanks to the actuating device, into a pendular packing which will tend to drill as it approaches the vertical.
- FIG. 9 represents a directed drilling rig used in particular for the so-called "build-up" drilling phase or for azimuth correction.
- the tool 40 is rotated by the bottom motor 47.
- Said device 45 is located above the engine.
- a variable angle elbow fitting 48 such as that taught in patent FR-2432079, can be controlled by the actuating device.
- Conventional tubular elements 49 complete the drill string.
