Description

<Desc / Clms Page number 1>

 The invention relates to a device for completing an installation for operating fluids contained in a basement.

 One field of application of the invention relates to the exploitation of oil drilling for the purpose of extracting petroleum and / or natural gas from the subsoil.

To extract the fluid contained in the subsoil, a hole is first made from the surface of the soil passing through underground layers in which fluid is present. A longitudinal conduit is then introduced into the hole in order to collect the fluid.

 In many cases, the longitudinal duct successively crosses several underground layers which do not communicate with each other in the basement and each containing fluids to be exploited which may be of different compositions. There is a known completion device in which a cemented casing is placed on the inner wall of the through hole, holes are made in the casing to allow fluid from the underground layer passed through, the longitudinal duct is provided with several orifices passage of fluid positioned in the different layers containing the fluids to be collected and the different layers containing the fluids to be exploited are isolated between them by gaskets inserted between the consecutive orifices and between the inner casing of the hole and the longitudinal collecting duct . Each orifice of the duct can be opened or closed by a shutter member controlled by sending an actuating fluid to an actuating piston associated with each shutter member.

 This completion device has the drawback of being very expensive and complicated to implement, in particular with regard to the means for controlling the shutter members, which are bulky and not very flexible to use. In addition, the linings used can be deteriorated by the temperature increases that may occur, so much so that fluid from one layer can pass into the neighboring layer through the lining, in contrast to the fluid tightness sought.

de l'état de la technique. The invention aims to obtain a device for completing an installation for operating fluids contained in a basement, overcoming the drawbacks

state of the art.

 A first object of the invention is a device for completing an installation for operating fluids contained in a basement, the device

 comprising a longitudinal fluid collection conduit, intended to be introduced into a fluid passage hole formed in said basement, the collection conduit comprising at least one orifice, provided in a determined longitudinal position, allowing fluid to pass from the outside to the inside of the collecting duct and associated with a member for closing the orifice, capable of being controlled in an open state or in a closed state of the orifice by control means , means for sealing an area of the through hole in which the orifice is located with respect to another area of the through hole, being fluid-tight, being provided between the collecting duct and the through hole, characterized in that the means sealing comprises at least one module for local constitution of a sealing mass between the collecting duct and the through hole, the constitution module comprising a housing secured to the wall exterior of the collection duct, provided in a longitudinal position remote from the position of the at least one orifice and comprising at least one exterior wall intended to be applied against the passage hole and delimiting a chamber for introducing the sealing mass, at least one reservoir being provided in the housing to contain a volume of at least one constituent of the sealing mass, the presence of which is necessary to constitute the sealing mass, control means being provided for sending the constituent of the reservoir to the introduction chamber.

 Thanks to the invention, it is no longer necessary to place a casing inside the through hole over its entire depth and one can even dispense with such a cementing step. Perforations in the casing are thus also dispensed with, which makes it possible to increase the height of passage of fluid from the underground layer to the collection conduit to the entire height thereof. The cross section of the hole, left free for the passage of the collecting duct, is also increased, which makes it possible to use a collecting duct of larger cross section. With an equal cross section of collection conduit, it is thus made possible to drill a passage hole of smaller cross section, which reduces the quantity of drill cuttings to be raised from the hole and contributes to solving the environmental problems associated with the danger and congestion of these cuttings. Thus, thanks to the invention, two underground layers containing fluid can be made watertight relative to each other by arranging the module

 In FIG. 1, the completion device 1 comprises a longitudinal conduit 2 for collecting fluid, introduced into a passage hole 3 provided beforehand by any suitable means in a basement 4 and of internal diameter greater than the maximum external diameter of the conduit 2. The conduit 2 is for example in the form of a circular cylindrical tube, as is the through hole 3. The pipe 2 and the hole 3 extend in a general longitudinal direction 5 of driving into the basement 4. Although the pipe 2 and the hole 3 are represented as being vertical with respect to the surface 6 of the ground, this

<Desc / Clms Page number 11>

 does not exclude that the longitudinal direction 5 of the conduit 2 and the hole 3 is inclined at a determined angle relative to the surface 6 of the self for example from 0 degrees to 90 degrees relative to the vertical.

 The collecting duct 2 is connected by its upper part to members 7 for holding in position intended to be connected to an installation for exploiting the fluids collected by the duct 2, not shown. The conduit 2 can be formed, as is known from several sections connected to each other. The collecting duct 2 has in its wall a plurality of orifices 8 provided respectively in a plurality of determined longitudinal positions, spaced from one another. Each orifice 8 makes it possible to pass fluid from the exterior of the conduit 2 towards the interior of the conduit 2.

 Above and below each orifice 8 of the duct 2 is provided a fluid sealing member 9, delimiting a fluid collection stage in which the associated orifice 8 is located. The sealing members 9 are arranged longitudinally around the duct 2 in longitudinal positions above and below an underground layer 10 containing fluids to be collected and opening into the collection stage delimited by these sealing members 9 . Thus, the arrangement of the orifices 8 and of the sealing members 9 is adapted to the geological configuration of the layers traversed by the hole 3. This configuration is determined beforehand by any appropriate coring and detection operation, as is known. The number of longitudinal positions of orifices in the collecting duct 2 can be arbitrary and is for example typically from 3 to 5 but can reach 20. Of course, a single orifice 8 provided in a single determined longitudinal position on the duct 2 can be provided and in this case two sealing members 9 disposed above and below this orifice 8 are provided or a single sealing member 9 above the orifice 8. To collect the fluid present in the one of the underground layers 10, one of the openings 8 is left open in one of the longitudinal positions and the other openings 8 are closed using shutter members which will be described below.

To collect fluid from another underground layer 10, all the holes 8 are closed, then the hole 8 located in the longitudinal position located in this other underground layer 10 is opened, keeping the other holes 8 closed using obturation organs. It is thus possible in turn to open the orifices 8 along the collecting duct 2. You can also leave several openings open

<Desc / Clms Page number 12>

 8 or all the orifices 8. The passage hole 3 is for example internally reinforced by a casing 11 for example of cement extending longitudinally from the surface 6 of the ground to the sealing member 9 encountered first . It is mounted on the collecting duct 2 above this first sealing member 9 encountered, a coupling 2a for coupling and uncoupling the upper duct section connected to the members 7 to the lower duct section. This connection 2a includes a safety valve.

 According to the invention, one or more of the sealing members 9 is formed by a module 12 of local constitution of a sealing mass between the conduit 2 for collection and the passage hole 3. Each of the sealing members 9 is for example formed by a module 12 of local constitution of a sealing mass.

In Figure 2, the module 12 of constitution is fixed in a determined longitudinal position of the conduit 2 for collection, being at a distance from the longitudinal position of the orifice (s) 8 nearby. The module 12 includes a housing 13 fixed to the outer wall 14 of the conduit 2 for collection or forming a part of it. The housing 13 is of annular cross section surrounding the duct 2, the wall 14 of which has, for example, recesses
15a for anchoring complementary parts 15b for anchoring the housing 13 ensuring the continuity of the collecting duct 2, in a fluid-tight manner. The housing 13 surrounds the duct 2 on a longitudinal portion of the latter and comprises an outer wall 16 located at a distance from the wall of the duct 2, and for example fixed to the anchoring parts 15b by screwing or other, metal joints 15c being inserted between the anchoring parts 15b and the outer wall 16. The outer wall 16 is provided at a distance from the passage hole 3, when the collecting duct 2 is positioned in the hole 3 for collecting fluids. The outer wall
16 is integral with two annular outer walls 17 and 18 for application, extending transversely to the longitudinal direction 5 of the wall 16 and outwards, spaced longitudinally from one another and intended to be applied by their free edge 19 against the through hole 3. The transverse outer walls 17 and 18 are for example each formed of an annular cup anchored in the wall 16 supporting them. The transverse walls 17 and 18 of application, the external wall 16 and the passage hole 3 delimit between them a chamber 20 for introducing a mass

<Desc / Clms Page number 13>

 sealing. The wall 16 comprises means for gripping the sealing mass in the introduction chamber 20, formed for example by notches 16b formed by peripheral grooves or peripheral ribs, so as to retain the sealing mass by relative to the housing 13.

 In FIGS. 2 and 3A, the housing 13 comprises a first reservoir 21 containing a volume of a first constituent of the sealing mass and a second reservoir 22 containing a volume of a second constituent of the sealing mass. The tanks are for example annular in the housing 13 around the duct 2. The sealing mass is formed by mixing the first and second constituents. The first and second constituents contained in the first and second reservoirs 21 and 22 have a composition such that they are not solidified when they are in their reservoir and that they can be solidified to form the sealing mass when they have been mixed beforehand. The volume of the first constituent contained in the first reservoir 21 is for example greater than that of the second constituent contained in the second reservoir 22, the first reservoir 21 being located above the second reservoir 22.

 The first and second constituents are contained in a fluid phase, for example in liquid or pulverulent form, so that they can be sent to the introduction chamber 20. The first and second constituents of the sealing mass are, for example, those of a storable liquid two-component completion cement. Of course, first and second constituents other than this cement can also be provided, for example a two-component epoxy resin with filler which can be hardened into a sealing mass by mixing. Of course, the invention is also applicable to a larger number of tanks comprising two or more of two constituents of the sealing mass. In a variant, there is provided in the housing a single reservoir containing at least one constituent of the sealing mass and a retarding agent for constituting sealing mass, the contents of the reservoir then being sent to the introduction chamber before the end of the activity of the delaying agent. In another variant, the housing comprises a reservoir containing at least one thermosetting material forming constituent of the sealing mass, said reservoir being able to store said material in the uncured state, the chamber

<Desc / Clms Page number 14>

 of introduction being at a temperature such that the resin introduced into it hardens to form the sealing mass.

 Control means, described below, are provided to cause the mixture of the first and second constituents contained in the first and second reservoirs 21, 22 and to cause the mixture of the first and second constituents to be sent into the chamber 20 of introduction.

 In FIGS. 3A, 3B and 6, the housing 13 comprises first and second lines 23, 24 connecting the first and second tanks 21 and 22 to a mixing chamber 25. The mixing chamber 25 communicates with the introduction chamber 20, via a passage 26 arranged in the outer wall 16 between the application walls 17,18 and for example in the form of a grid. The mixing chamber 25 has a peripheral groove 25b near the passage 26.

 It is interposed on the connecting line 23, between the first tank 21 and the mixing chamber 25, a first member 27 for interrupting circulation, having an open position for letting the first constituent of the first tank 21 pass through the mixing chamber 25, when the pressure of the first component in the first tank 21 is greater than a determined threshold pressure, and a closed position preventing the passage of the first component from the first tank 21 to the mixing chamber 25, when the pressure of the first constituent in the first reservoir 21 is less than said determined threshold pressure.

 It is interposed on the connecting pipe 24, between the second tank 22 and the mixing chamber 25, a second member 28 for interrupting circulation, having an open position for letting the second component of the second tank 22 pass through the mixing chamber 25, when the pressure of the first component in the second tank 22 is greater than a determined threshold pressure, and a closed position preventing the passage of the second component from the second tank 22 to the mixing chamber 25, when the pressure of the second constituent in the second reservoir 22 is less than said determined threshold pressure.

 The first and second interrupting members 27, 28 are for example formed, as shown in FIG. 6, each by a non-return valve normally closed and preventing return to the closed position.

<Desc / CRUD Page number 15>

 when it was moved to the open position. As shown, the interrupting members 27, 28 are provided at the ends of the connecting pipes 23, 24, opening into the mixing chamber 25.

 In FIG. 6, the non-return valves 27 and 28 each comprise a seat 29 located at the end of the connecting pipe 23, 24 opening into the mixing chamber 25 and capable of being closed by a ball 30, when that -this is applied against its associated seat 29. The sealing by the balls prevents the passage of constituents of the sealing mass from the connection pipe 23,24 towards the mixing chamber 25 and the passage of fluid from the mixing chamber 25 towards the connection pipe 23,24 . There is provided in the mixing chamber 25 a pusher 31 applied against the balls 30 and guided in a rectilinear direction 31 c in the mixing chamber 25. The mixing chamber 25 further comprises a member 32 for prestressing the pusher 31 against the balls 30 holding the balls 30 in their seat 29 in the closed position of the connecting pipes 23, 24, when the constituent pressure in the pipes link 23,24 is less than the determined threshold pressure. The pusher 31 is common, as shown, to the two balls 30 associated with the connecting pipes 23 and 24 and has transverse openings 31b to allow the components to pass.

 In FIG. 6, the mixing chamber 25 comprises, for each ball 30, a housing 33 connected to the seat 29 by a guide passage 34. When the pressure in the connecting lines 23 and 24 is greater than the determined threshold pressure, the balls 30 are pushed out of their seat 29 towards their associated guide passage 34 against the force exerted by the pusher 31 to arrive in their respective housing 33 where they remain trapped. The housing 33, the pusher 31 and the prestressing means 32 are arranged such that when the balls 30 are in their respective housing 33, the connecting pipes 23, 24 are in the open position.

 The direction of guidance of the pusher 31 in the mixing chamber 25 is oblique to the trajectory of each ball 30 when it passes from its seat 29 to its housing 33 and comprises a component 31 d of movement common with this trajectory. The housings 33 and the guide of the pusher 31 in the mixing chamber 25 are arranged so that the displacement of one of the balls 30 out of its seat 29 causes the recoil of the

<Desc / Clms Page number 16>

 pusher 31 in its guiding direction 31c of the displacement component 31c, which allows the other ball (s) 30 to also be moved out of their seat 29 due to the force exerted by the sending of constituents to these other balls 30. Thus, even if during the sending of the constituents in the connecting pipes 23, 24 the pressure of the constituent in one of the connecting pipes 23, 24 alone did not allow the corresponding ball to be displaced, it suffices that another ball is moved into its housing 33, to also allow said corresponding ball to be moved out of its seat. It is thus guaranteed that the non-return valves 27, 28 pass almost simultaneously from the closed position to the open position.

 The control means are capable of passing the pressure of the constituents in the reservoirs 21, 22 from a value lower than the determined threshold pressure to a value greater than this determined threshold pressure.

 The control means comprise, in each reservoir 21, 22, a movable piston 35 sharing this reservoir, for example in a fluid-tight manner, in a first chamber 36 containing the volume of sealing mass constituent on a first side of the piston 35, and in a second chamber 37 for receiving a fluid under displacement pressure of the piston 35. The displacement fluid is a liquid completion fluid, for example water, salt water, or l water added with diesel, or gaseous. The first chamber 36 communicates via an outlet 38 with the associated connection pipe 23, 24. The sending of the displacement fluid at a pressure greater than a determined value in the first receiving chamber 37 causes the piston 35 to move in the reservoir, pushing the constituent contained in the second chamber 36 towards the outlet 38 in the chamber 25 of mixed. Of course, other means for moving the pistons 35 in the reservoirs 21, 22 to send the constituents to the mixing chamber can be provided. The piston 35 may also not be fluid-tight but limit the passage of displacement fluid from the second chamber 37 for receiving the displacement fluid to the first chamber 36 containing the volume of sealing mass constituent. In this case, the piston 35 plays the role of a separator isolating one from the other to a large extent the chambers 36 and 37. Thus, even in the event of the piston 35 bracing in its reservoir, the displacement fluid still allows the constituent to be sent to the chamber 20 for introduction by

<Desc / Clms Page number 17>

 application of the displacement fluid directly to the component in the reservoir, through the connection of the piston 35 with the interior walls of the reservoir.

 In FIGS. 2 and 4, the reception chambers 37 are connected to a means for supplying the displacement fluid. The displacement fluid is brought through the interior 2b of the conduit 2 to the first reception chambers 37 by means of first and second supply conduits 39.40 opening respectively into the chamber 37 for receiving the first and second reservoirs 21, 22. Several supply lines can be provided for the same reception room 37. The supply lines 39.40 pass through the chambers 36 of the reservoirs 21.22 and the pistons 35 in a fluid-tight manner, which are able to slide relative to them. The supply lines 39.40 are for example fixed inside the chambers 36 by screwing on the inside of a wall of the latter. The first and second supply lines 39.40 can be connected separately to the inside 2b of the pipe 2 or, as shown, can be connected to the inside of the pipe 2 via a common supply pipe 41.

 Means 42 for controlling the circulation of displacement fluid in the supply line 41 are provided. The circulation control means 42 comprises a state of closure of the common supply line 41 and a state of passage of movement control fluid in the common supply line 41. The circulation control means 42 is such that it passes from the obturation state to the passage state, when displacement control fluid having a pressure greater than a determined threshold value is sent into the common pipe 41 for supplying to the means 42 from the interior 2b of the conduit 2. In the state of passage of the means 42, the displacement fluid arrives via the common supply conduit 41 to the chambers 37 for receiving the first and second reservoirs 21.22 via the first and second supply lines 39.40, which pushes the piston 35 in the tanks 21.22 against the constituents present in the chambers 36 and sends these constituents in the conduits 23.24 connection to the mixing chamber 25. The force then exerted by the pistons 35 on the constituents present in the reservoirs 21,22 is sufficient to exert a pressure in the connecting pipes 23,24 greater than the determined threshold pressure of the

<Desc / Clms Page number 18>

 organs 27, 28 for interrupting circulation, to cause them to pass into the open position, which allows the first and second constituents to arrive in the mixing chamber 25 where they are mixed, then to pass through the passage 26 in the introduction chamber 20 where they can solidify into a sealing mass between the passage hole 3 and the housing 13, as shown in FIG. 3B. The sealing mass formed in the introduction chamber 20 is made integral with the housing 13, in a fluid-tight manner, by the gripping means 16b. The sealing mass formed in the introduction chamber 20 makes it possible at the same time to anchor the conduit in the passage hole 3.

 In order to simultaneously cause the introduction of all the components into the chamber 20, the means 42 for controlling the circulation of displacement fluid is for example formed, as shown in FIG. 4, by a rupture disc 43 closing off the common pipe. 41 for supplying displacement fluid, as well as a stop member 44 applied behind the contour of the disc 43 in the direction 46 of sending displacement fluid in the common supply pipe 41. A single disc 43 is provided, as shown, but, if necessary, several discs 43 can be provided. The rupture disc 43 is arranged so that when the displacement fluid pressure applied thereto from the common pipe 41 becomes greater than said determined threshold value, the disc 43 is pressed against the stop member 44, which breaks the disc 43 to let the displacement fluid pass to the first and second supply lines 39.40.

 In order to speed up the introduction of the mixture of constituents into the introduction chamber 20, the housing 13 includes an expansion chamber 48, located above one of the first and second reservoirs, 21, 22, and for example above the chamber 37 for receiving the reservoir 21. Means 49 are provided in the housing 13 for connecting the expansion chamber 48 to the chamber 20 during the introduction of the sealing compound therein.

 In FIG. 5, the connection means 49 are formed by a communication pipe 50 between the introduction chamber 20 and the expansion chamber 48, comprising a part 50a opening into the introduction chamber 20, a part 50b opening into the expansion chamber 48 and a part 50c for interposing a valve 51. The valve 51 is guided in the part 50c

<Desc / Clms Page number 19>

 of the communication line 50 in a direction 52 of movement between a closed position of the communication line 50 and a position for passage of fluid in the communication line 50. The pressure in the expansion chamber 48 in the closed position of the communication line 50 is lower than that of the introduction chamber 20. The expansion chamber 48 can be pressurized with nitrogen at a pressure close to the pressure prevailing in the geological formation of the hole 3 and of the introduction chamber 20 in the closed position of the communication line 50, to optimize the suction time of the fluid initially present in the introduction chamber 20 in the passage position and thus controlling the cementation in the introduction chamber 20 and the risks of destruction of the valves 51.

 A pin 53 is provided in the stroke of the valve 51 from its closed position shown in FIG. 5 to its passage position, to maintain the valve 51 in its closed position. The pin 53 passes, for example, through a hole in the valve 51. A member 54 for breaking the pin 53 is provided on the valve 51 and is for example formed by the inner wall of the hole for the passage of the pin 53 in the valve 51. transversely to the direction 52. The valve 51 is integral with a member 55 for moving from the closed position to the position for passage of fluid. The displacement member 55 comprises an arm connected by one end to the valve 51 and by another end to a detent piston 56 guided in the direction 52 in the chamber 37 for receiving the fluid for displacing the fluid from the first reservoir 21. When the displacement fluid pressure prevailing in the chamber 37 for receiving the first reservoir 21 becomes greater than said predetermined threshold value, the force exerted on the piston 56 by the displacement fluid presses the rupture member 54 against the pin 53 of way to break this one. The piston 56 is then pushed by the fluid to move the valve 51 from the closed position to the passage position. When the pressure prevailing in the receiving chamber 37 is less than said predetermined threshold pressure, the pin 53 is able to hold the valve 51 in the closed position. In the passage position of the valve 51, the fluid initially present in the introduction chamber 20 before the introduction of the sealing mass is expelled into the expansion chamber 48.

 In another application, the building module 12 can be used to plug an orifice 8 in a determined longitudinal position, for example in the case where the shutter member of this orifice 8 can no longer pass into the shutter position .

 We will now describe the means for controlling the members for closing the orifices 8 of the collecting duct 2.

 In FIGS. 7A, 7B, 7C, 7D, 7E and 7F, the collecting duct 2 comprises an inner longitudinal section 60, in which an orifice 8 for the passage of fluid is formed in a determined longitudinal position. The orifice 8 is for example present in the form of several oblong holes 8b longitudinally transversely crossing the wall of the section 60 and regularly distributed in a ring therein around the interior 2b of the conduit 2 for collection in said determined position, thus as shown, in order to allow the passage of a larger quantity of fluid in the orifice 8.

 There is associated with the orifice 8 a shutter member designated by the general reference sign 61 and mounted on the outer surface of the section 60 of the duct 2. A shutter member 61 is provided for each longitudinal position of the orifices 8. The shutter member 61 comprises a sliding jacket 62 surrounding the section 60. The jacket 62 has openings 63 having an arrangement and a shape corresponding to those of the holes 8b of the section 60 and shutter plates 64 offset longitudinally with respect to the openings and also having an arrangement and a shape corresponding to those of the holes 8b of the section 60. The jacket 62 is movable between one and the other from an opening position of the orifice 8, shown in FIGS. 7A, 7C and 7E, in which the openings 63 are opposite the holes 8b and fluid can pass through the orifice 8 from the outside towards the inside of the duct 2 or from the outside towards the inside of the duct 2, and a po sealing position, represented in FIGS. 7B, 7D and 7F, in which the obturating plates 64 are opposite the holes 8b and prevent the passage of fluid in the orifice 8 from the outside towards the inside of the duct 2 or of the outside towards the inside of the duct 2. The passage of the jacket 62 between one and the other of the open and closed positions is carried out by translation in the longitudinal direction 5 of the duct 2, as shown . However, the invention is also applicable to any other trajectory of the shutter member 61 between the open and shutter positions.

<Desc / Clms Page number 21>

 The jacket 62 is surrounded externally by a sleeve 65 fixed by its two longitudinal ends 65a, 65b on the two longitudinal ends of the section 60 of the duct 2, on either side of the jacket 62. It is thus avoided that the operation of the shutter member 61 is not disturbed by the fluid present inside the pipe 2b 2 and it is made possible that the inside of the section 60 is without obstacle to the passage of fluid. The sleeve 65 has between its ends 65a, 65b a compressible strainer 65c extending in front of the orifice 8 having a multiplicity of holes 65d to allow fluid to pass from the exterior of the sleeve 65 towards the interior thereof and from the inside of the sleeve 65 to the outside of the latter.

It is delimited between the sleeve 65 and the section 62 of the conduit 2 a chamber 66 for receiving actuating fluid, in which the jacket 62 is movable between one and the other of the open and closed positions. The jacket 62 has first and second extreme sides 67,68 spaced apart longitudinally in the receiving chamber 66, separated in a fluid-tight manner by seals, and dividing the receiving chamber 66 into a first partial chamber 70 associated with the first side 67 and a second partial chamber 71 associated with the second side 68. The extreme sides 67, 68 of the jacket 62 thus form in the receiving chamber 66 a piston 62 for actuating the jacket 62 between one and the other of its open and closed positions, this actuating piston 62 being symbolized in FIGS. 8,11 and
12 by a piston having the two opposite sides 67,68.

 The first and second partial chambers 70, 71 of the chamber 66 for receiving the actuating fluid are connected respectively to first and second conduits 72, 73 for bypassing the actuating fluid, formed in the longitudinal ends 65a, 65b of the sleeve. 65. The plurality of first and second bypass lines 72, 73 are connected to a common actuating fluid supply circuit, designated by the general reference 74, and comprising a first common line 75 for supplying fluid. actuation and a common line 76 for actuating fluid delivery. As shown in FIGS. 3A and 3B, the common lines 75, 76 of actuating fluid extend longitudinally to the conduit 2 while being fixed to the latter and successively pass through the housings 13 of the modules 12 for constituting sealing mass , passing for example in

<Desc / Clms Page number 22>

 reservoirs 21, 22 and in chambers 48, 36, 37. The bypass lines 72, 73 are located in the wall of the line 2, near their associated orifice 8. The common line 75 for supplying actuating fluid is connected at the surface 6 to a source 77 sending actuating fluid therein, such as for example oil. The actuating fluid delivery pipe 76 is connected at the surface 6 to a secure container 78 for collecting actuating fluid. There is provided on the first and second pipes 72, 73 for actuating fluid bypass, respectively a member 79, 80 for controlling the circulation of actuating fluid. In a variant not shown, an actuating fluid circulation control member is provided only on one of the first and second bypass lines 72, 73.

 In FIGS. 7A, 7B, 7C and 7D, the actuating fluid circulation control members 79.80 are provided in fluid-tight housings externally fixed to sections 60b of the conduit 2 connected to the section 60. In FIGS. 7A and 7B, the first and second members 79.80 for controlling the circulation of actuating fluid are provided in different housings 791.801 fluid-tight fixed externally to two sections 60b of the conduit 2 connected to the ends opposite to the section 60, in a symmetrical arrangement . In FIGS. 7C and 7D, the first and second members 79, 80 for controlling the circulation of actuating fluid are provided in the same fluid-tight housing 792 fixed externally to a section 60b of the conduit 2 connected to one end of the section 60, in an asymmetrical arrangement. The first and second actuating fluid bypass lines 72, 73 are connected to the actuating fluid circulation control members 79, 80 in their sealed housing and comprise sections 72a, 73a for connection between the sleeve 65 and the or the boxes.

 The actuating fluid circulation control members 79, 80 are for example provided in the form of solenoid valves. Each actuating fluid circulation control member 79, 80 has several circulation positions and an actuating fluid circulation control input 81, which is the electrical position control coil in the case of a solenoid valve.

<Desc / Clms Page number 23>

 As shown in FIGS. 9A and 9B, each input 81 for controlling the circulation of actuating fluid is connected to a common circuit 82 for sending instructions for circulating actuating fluid by means of branch 83 associated. The common circuit 82 for sending circulation instructions is connected to a generator 84 for instructions for circulation of actuating fluid, disposed on the surface 6 of the installation, and passes longitudinally through the modules 12 of constitution, corresponding passages being provided therein.

In the case of solenoid valves as control members 79.80, the circuit 82 for sending instructions is electric and is connected to the coil of these, the sealed housings 791, 801, 792 have a sealed passage for the branch 83, and the circuit 82 for sending instructions is electrically shielded. The electrical wires of the circuit 82 for sending instructions are formed of electrical conductors coated with an insulating sheath and for example fixed inside one of the common lines 75, 76 for supplying and discharging fluid. actuation, to reduce their size and avoid having to provide passages for them. The generator 84 also sends to the control inputs 81 the energy necessary for the functioning of the organs
79.80 of order.

The generator 84 sends for example the traffic instructions in coded form to the common circuit 82. Each branch 83 bypass comprises, between the node 85 connecting it to the circuit 82 for sending instructions and the input
81, a filter 86 for detecting traffic instructions, capable of decoding the instructions sent in the circuit 82. The coding of the instructions generated by the generator 84 concerns the position that the control member 80 must take and that of the actuators 80 for which the instruction is intended. A filter 86 is associated with each control input 81 on its branch 83 bypass. The filters 86 permanently decode the instructions arriving from the common circuit 82 to the branch branch 83. Each member
79.80 of control comprises at least a first position of circulation of actuating fluid, which it takes when its control input 81 receives a first signal, and a second position of circulation of actuating fluid, which it takes when its control input 81 receives a second signal.

 Each filter 86 has an instruction decoding circuit 87 and a circuit 88

<Desc / Clms Page number 24>

de commande. Les filtres 86, le circuit 87 de décodage d'instruction et le circuit 88 de fourniture sont agencés pour transmettre l'énergie électrique nécessaire au fonctionnement des organes 79,80 de commande du circuit 82 aux entrées 81 de ceux-ci. Chaque filtre 86 est contenu dans un boîtier étanche comportant une traversée étanche pour le passage de la branche de dérivation 83 vers le circuit 82 et vers l'entrée 81. A la figure 9A, l'entrée 81 est mise entre la masse et la branche 83 reliée au circuit 88 de fourniture. A la figure 9B, l'entrée 81 est mise entre les bornes du filtre 86. of respectively supplying the first signal or the second signal, when the associated decoding circuit 87 decodes that the instruction present on the branch 83 is respectively intended for this control input 81 among all the control inputs 81 or is not not intended for this entry 81

control. The filters 86, the instruction decoding circuit 87 and the supply circuit 88 are arranged to transmit the electrical energy necessary for the operation of the control members 79,80 of the circuit 82 to the inputs 81 thereof. Each filter 86 is contained in a sealed housing comprising a sealed passage for the passage of the branch branch 83 towards the circuit 82 and towards the inlet 81. In FIG. 9A, the inlet 81 is placed between the ground and the branch 83 connected to the supply circuit 88. In FIG. 9B, the input 81 is placed between the terminals of the filter 86.

 The generator 84 codes the instructions for example in frequency, a different instruction frequency being associated with each control input 81, as shown in FIG. 10. Each instruction corresponds to a sinusoidal signal of frequency f associated with the input 81 control for which it is intended, and of determined duration D, corresponding to an activation time of this control input 81 allowing the passage of the control member 79.80 in the first position or in the second position. The decoding circuit 87 comprises for example a bandpass filter allowing only the frequency f associated with its control input 81 to pass.

 In FIG. 8, each control member 79.80 is of the switch type and has a first access 89 connected by the bypass pipe 72,73 to the chambers 70,71, a second access 90 of actuating fluid connected by a branch 91 to the line 75 for sending actuating fluid, and a third port 92 for actuating fluid connected by a branch 93 to the line 76 for discharging actuating fluid. The member 79.80 is of the switch type and is able to communicate the first port 89 either with its second port 90 in the first circulation position, or with its third port 92 in the second circulation position. The control signals arriving at the control inputs 81 are such that, when the control member 79 is in its first circulation position, the control member 80 is in its second circulation position, and vice versa. When the actuating fluid reaches the chamber 70, the piston 62 is pushed back by its

<Desc / Clms Page number 25>

 side 67, which moves the drawer from its open position to its closed position. When the actuating fluid reaches the chamber 71, the actuating fluid pushes the piston 62 by its side 68, which moves the slide 62 from its closed position to its open position.

In FIG. 11, the bypass pipe 72 is connected on the one hand to the chamber 70 and, on the other hand, by a node 94 to a branch 95 for connection to the line 75 for sending actuating fluid and to a branch 96 connecting to the line 76 for actuating fluid delivery. Likewise, the bypass pipe 73 is connected on the one hand to the chamber 71 and, on the other hand, by a node 97 to a branch 98 connecting to the line 75 for sending actuating fluid and to a branch 99 for connection to line 76 for actuating fluid delivery. A member 79a, 79b for controlling the circulation of actuating fluid of the switch type is interposed respectively on the connecting branch 95, 96. A member 80a, 80b for controlling the circulation of actuating fluid of the switch type is interposed respectively on the connecting branch 98, 99. The control members 79a, 79b, 80a, 80b are of the normally closed circulation switch type and have a first position, shown in the figure
11, in which they do not allow actuating fluid to pass through their connecting branches 95,96, 98,99, and a second position 100 in which they allow actuating fluid to pass through their connecting branches 95,96 , 98,
99. The presence of the first or second signal on the input 81 for controlling the control members 79a, 79b, 80a, 80b causes them to pass respectively into their first position or into their second position.
When control signals are sent to the control inputs 81 so that, when the control member 79a is in the second passage position, the control member 79b is in the first non-passage position, the control member 80a is also in the first non-passage position and the control member 80b is in the second passage position, actuating fluid is sent into the chamber 70 and is discharged out of the chamber 71, to push the side 67 of the piston 62 and move the slide 62 from the open position to the closed position. Conversely, when control signals are sent to the control inputs 81 so that, the control member 79a is in the first non-passage position, the control member 79b is

<Desc / Clms Page number 26>

 in the second passage position, the control member 80a is in the second passage position and the control member 80b is in the first non-passage position, actuating fluid is sent to the chamber 71 and is pushed out of the chamber 70, to push the side 68 of the piston 62 and move the drawer 62 from the closed position to the open position.

 In FIG. 12, the means for controlling the piston 62 are identical to those of FIG. 11 and will be designated with the: same reference signs, apart from the modifications indicated below. The control members 79b and 80b are replaced by first and second piloted valves 101 and 102 respectively, interposed in the connecting branches 96 and 99 and associated respectively with their node 94,97. Each piloted valve 101, 102 has an inlet 103, 104 for piloting by actuating fluid pressure, connected respectively to node 94, 97 associated with the respective respective pilot valve 102, 101. When the fluid pressure prevailing on its pilot input 103, 104 is lower than a prescribed pressure, the corresponding piloted valve 101.102 does not allow the passage of actuating fluid in the branch 96.99, on which it is interposed. When the pressure prevailing in its respective pilot inlet 103, 104 is greater than said prescribed pressure, the corresponding piloted valve 101, 102 lets the actuating fluid pass through the branch 96.99 on which it is interposed. The control signals are sent to the control inputs 81 of the control members 79a, 80a so that, when one of these is in the second passage position, the other control member 80a, 79a found in the first non-passing position.

 Thus, when the control member 79a is in the second passage position, actuating fluid is sent into the chamber 70 towards the side 67 of the piston 62. The pressure then prevailing in the bypass line 72, in the node 94 and in the piloting inlet 104 is greater than the prescribed pressure, which causes the piloted valve 102 to pass from the non-passage position to the position for passage of actuating fluid in the connecting branch 99. The actuating fluid is sent into the chamber 70 towards the side 67 of the piston 62 and is discharged from the chamber 71 towards the discharge line 76 by the bypass pipe 73 and the branch 99, the connecting branch 98 being closed.

<Desc / Clms Page number 27>

 by the control member 80a. The side 67 of the piston 62 is then pushed by the actuating fluid, which moves the slide 62 from the open position to the closed position.

 Conversely, when the control member 80a is in the second passage position and the member 79a is in the first non-passage position, the actuating fluid is sent to the connecting branch 98, the pipe 73 bypass and chamber 71. The pressure prevailing in the connecting branch 98, in the node 97 and the piloting inlet 103 is then greater than the prescribed pressure, which causes the piloted valve 101 to pass from the no position -passing to the position of passage of actuating fluid in the connecting branch 96. The actuating fluid is then discharged from the chamber 70 in the bypass pipe 72 and in the connecting branch 96 to the discharge line 76 . The side 68 of the piston is pushed, which moves the slide 62 from the closed position to the open position.

 Thanks to the invention, a more reliable and less expensive completion device is obtained, which can be used in basement operating installations comprising a large number of fluid sampling layers.
