Definitions
- the invention relates to a rapid valve actuator, as well as to a tool provided with this actuator.
- One field of application of the invention relates to valves intended to be put in place in a basement operating conduit such as for example in oil or gas production wells and any eruptive well for withdrawing hydrocarbons present in the basement, or any injector well.
- Production wells usually include an underground wall with holes for passing the fluid produced from the surrounding production layer towards the interior of the well, then raising it to the surface thanks to the fluid pressure prevailing in this layer.
- the operator of the well has the greatest interest in having a large quantity of fluid produced up the well per unit of time, that is to say that the production yield is as high as possible.
- This production yield can be influenced by different parameters and conditions.
- One of these parameters relating exclusively to the structure of the drilled well, is the cross section of the passage of fluid produced between the underground layer and the wall of the well. The larger this passage section, the more a large quantity of fluid can be raised from the well.
- This passage section can be polluted by materials and fluids such as drilling mud, casing cement, or solid materials transported by the fluid produced.
- the pressure measurement curves must be used with regard to their value but also their slope a as a function of time t.
- the time T that the measured pressure P takes to go from the production pressure P1 to the reservoir pressure P 2 is it equal to a value between half a day and ten days.
- the pressure curve is assimilated, at least during the first phase immediately following closure or complete opening, to a general first order curve in response to a flow step at level of the valve, characterizing the instantaneous passage between its closed state and its open state or vice versa.
- a steep slope of the curve of Figure 1 indicates a thin skin or a slightly obstructed passage section, providing a higher production yield. It is then possible to easily deduce therefrom information on the fluid passage section at the level of the production layer.
- the pressure response is assimilated to a curve of order greater than one, such as that represented in FIG. 2, in which the slope of the pressure as a function of time begins by increasing up to a point I of deflection, then decreasing, until that the pressure changes to steady state.
- a first object of the invention is a rapid valve actuator, comprising:
- valve actuator movable in the actuator body between one and the other from a valve closed position and a valve open position, characterized in that l the actuator further comprises:
- the drive device being capable of passing the driven member through a first stroke to a first release position
- a locking and triggering means fixed relative to the actuator body, cooperating with the driven member and the actuating member so that:
- the actuating member is fixed in the first determined position relative to the locking and triggering means and that the driven ⁇ rgàn ⁇ is movable relative to the means -of .. locking and triggering,
- the driven member when the driven member is in the first trigger position, the driven member is fixed relative to the locking and triggering means and the actuating member is pushed by the prestressing means relative to the locking and triggering, so that the actuating member passes from the first determined position to the second determined position.
- the invention allows rapid movement of the valve between the open or closed position and the closed or open position.
- the actuator is capable of causing several opening and closing movements of the valve. It is thus permitted to reassemble the valve and the tool comprising the latter in the open state after an opening movement or a closing movement followed by an opening movement, which was not possible with valves can only perform one closing.
- the actuator allows rapid opening and / or closing successively in several successive well production layers.
- the rapid closing and / or opening of the valve makes it possible to avoid its premature deterioration under the conditions of use.
- the fluid produced transports abrasive materials such as sand and passes through the valve with a very high speed. This high speed is due to the large pressure difference between the upstream and downstream sides of the valve, which increases when the fluid passage gap in the valve narrows at the end of closing and at the start of opening. Consequently, the fluid produced tends to apply against the slide valve or the movable piston of the valve during its closing or opening movement.
- the accumulation of energy in the actuator according to the invention also makes it possible to guarantee that the force exerted on the valve overcomes the resistance between its movable part and its fixed part, which may be due to the bonding of the sealing means between those -ci, resulting from the high temperature and pressure conditions prevailing in the well. Consequently, the actuator and the tool comprising the actuator are more reliable.
- the drive device is able to pass the member driven by a second stroke to a second trigger position, the means of prestressing being able to exert, when the driven member passes according to the second stroke to its second triggering position, a force of repulsion between them, tending to cause the actuating member to pass from the second determined position to the first determined position, and the locking and triggering means is configured to cooperate with the driven member and the actuating member so that:

- the wedging piece or pieces 43 are located against the outer guide surface 473 during the races C1 and C2. At the end of the first stroke C1, the wedging piece (s) 43 reach against the rear transverse edge 475.
- the piece (s) ) 43 of jamming passing from the recess 46 in the first recess 45, push longitudinally and jointly forward the rear transverse edge 475 until the guide sleeve 472 abuts against the front half 491 of the obviously 49.
- the process is similar for the second stroke C2 and the second trigger position.
- each leg 431 is provided with a jaw 433 forming a wedging piece 43, comprising an outer part 434 facing the jacket 23 and of longitudinal section of complementary shape to the second and fourth recesses 46, 50, and a part interior 435 facing the guide part 43 and of longitudinal section of complementary shape to the first and third recesses 45, 49.
- the recesses 45, 46, 49, 50 are for example in the form of grooves with a straight profile formed respectively in the guide part 47 and in the jacket 23, the wall 231 being in one piece with the jacket 23. Ramps complementary are provided on the parts 434, 435 and in the recesses 45, 46, 49, 50 to allow the longitudinal locking of the jacket 23 or of the driven member 31 relative to the legs 431.
- the legs 431 are made of a material having a certain flexibility allowing them to flex transversely in order to be able to pass from a recess 50, 46 to the other 45, 46 in the first and second trigger position and to be in the recess 46 or 50, against the guide piece 47 and between its recesses 45 and 49 in the races C1 and C2.
- the control of passage of the actuating member 21 in the first or second trigger position is carried out by controlling the drive device 35 so that it displaces the nut 32 to corresponding longitudinal positions on the rod threaded 33.
- This command is carried out for example by controlling means for supplying energy to the drive device 35, not shown and on board with the actuator and / or the tool at the bottom of the well.
- these supply means are provided in the form of a battery or an electric battery, the connection of which is controlled to the drive device 35 to rotate its shaft 34 in one direction or another during the stroke C1 or C2.
- the supply means can be provided so as to be able to make several races C1 and C2 without having to recharge or change them, which gives the actuator greater autonomy.
- the actuator body 2 has at its rear end a sealed passage 81 making it possible to electrically connect the drive device 35 to supply and control means, provided in a housing fixed to the body 2 of the actuator or extending from 'one piece this one.
- the drive device 35 comprises for example means for counting the revolutions of its shaft 34 and is for example a brushless drive device.
- the power supply to the actuator can also be carried out by cable connected on the surface to an electrical source.
- the actuator control can also be preprogrammed on the surface before it descends into the well. The connection of the supply means to the actuator then causes the program prerecorded in the actuator to proceed.
- sealing means 71 for the fluid produced.
- These sealing means 71 are for example provided in the form of a piston surrounding the pin 22 in the body 2 and bearing on its outer peripheral face turned towards the inside of the housing 2 a first seal 72 and its inner face facing the pin 22 a second seal 73 for sealing.
- the piston 71 is advantageously mounted to slide relative to the spindle 22 and to the body 2, in order to balance the pressure differences prevailing on either side longitudinally thereof.
- the seals 72 and 73 are thus better preserved from pressure differences on either side longitudinally.
- the internal space of the body 2 located behind the sealing means 71 is filled with an operating fluid, for example to a large extent incompressible under the operating conditions of the well.
- This operating fluid consists, for example, of an oil.
- the piston 8 of the valve 6 is connected with a longitudinal clearance to the fixing member 18 according to FIGS. 4 to 10 or according to FIGS. 3A to 3C.
- the fastening member 18 has at its front end a transverse shoulder 183 slidably inserted longitudinally in a rear housing 184 of the piston 8, delimited by stops before 185 and rear 186 thereof, which define between them a longitudinal movement determined for shoulder 183, less than the length existing between its open and closed positions.
- the shoulder 183 When the valve 6 is kept open, the shoulder 183 is held by the members 18, 19 and 21 against the rear stop 186, while when the valve 6 is kept closed as shown in FIG. 13, the shoulder 183 is held by the members 18, 19 and 21 against the stop before 185. When it then passes to the closing or opening of the valve 6 from the open or closed position, the movement of the shoulder 183 allows to make it arrive with a high speed in the corresponding direction against the opposite stop 185 or 186, thus exerting a shock on the piston 8, helping to take off its seals 9, 10 relative to the body 5.
- the piston 8 of the valve 6 comprises a single external front seal 10 and an interior rear central chamber 111 which can communicate on the one hand by a transverse conduit 112 with the outside of its support wall 11 and on the other hand by a longitudinal conduit 113 with the front space 14.
- the transverse conduit 112 opens into the hole 7.
- the conduits 112 and 113 have a fluid passage section produced in the well, lower than that of the hole 7.
- the chamber 111 is further delimited at the rear by a secondary piston 114 mounted to slide longitudinally and fixed to the member 18 in front of the shoulder 183.
- the secondary piston 114 closes by any suitable sealing means the communication between the conduits 112 and 113 through the chamber 111, while when in FIGS. 14B and 14C, the shoulder 183 is moved back against the stop 186, the secondary piston 114 allows the conduits 112 and 113 to communicate through the chamber 111, while preventing fluid from passing into the housing 184 and the actuator. In this way, the opening movement of the hole 7 by the piston 8 in FIG. 14C is preceded by its communication with the conduits 112 and 113 in FIG.
- This embodiment is particularly advantageous for weakly consolidated wells.
- the actuator 1 can be integrated into a tool 201.
- a tool 201 may comprise, in addition to the actuator 1 and the valve 6, a unit 204 comprising pressure, temperature sensors, flow and / or other parameters under the actuator 1 and means for recording the measurement information produced by the sensors.
- the tool 201 comprises, mechanically connected to each other from top to bottom, a member 207 for locking by anchoring against the conduit 203, comprising seals 208 for sealing the fluid produced against the conduit 203, the valve 6 , the actuator, a possible centralizer 209 with arches against the conduit 203 and the unit 204.
