Definitions

  • the present invention relates to a device propelled by hydraulic pressure allowing measurements and interventions during injection or production in a deviated well.
  • deflected well is meant here both the well deflected wells and those strongly deflected and which require pumping of the equipment to reach the producing area.
  • the invention is particularly applicable when it is a question of carrying out measurements, for example of pressure and flow, at the level of geological formations, or any other intervention in a well and when it is a question of highlighting , for example, the flow profile of the producing part of a deviated eruptive well.
  • the measuring or intervention instrument can be, for example, a logging probe. It is either electrically connected to the surface by a logging cable, or not connected to the surface, benefiting in this case from an autonomous power supply and an information storage memory.
  • the volume located above the locomotive is pressurized by pumping, so as to push the equipment (probe and extension ) in the deviated area of interest to the producer.
  • the measurements are made during the pushing phase when the probe is in the production zone, or during the ascent phase. They can advantageously be repeated.
  • the assembly of all the equipment is carried out by pulling on the cable. If the production tubing has a substantially constant internal diameter and since the linings ensure good sealing, it sometimes happens that a phenomenon of pistoning and therefore of suction of the fluid is observed, capable of creating pressure imbalances and displacements of fluid, leading to uncontrolled production.
  • US Patent 2,122,697 also mentions a sensor lowered by circulation by means of pumping and which is then anchored to the bottom of the well via a deformable membrane and springs, while US Patent 3,104,714 relates to a tool. pumped fitted with an electric cable and which includes pads which will brake and prevent the tool from rising.
  • the first step is to introduce all of the tools into a pressurized well.
  • a device according to the present invention which can be used to carry out, during injection or fluid production operations, measurements or interventions in a deviated well passing through a geological formation, this well being fitted with casing.
  • This device comprises at least one measuring or intervention instrument fixed to a first end of an extension, the other end of which constitutes the upper end, is provided with sealing members enabling the device to be propelled into said casing. under the effect of hydraulic pressure, the device being, moreover, connected to the surface by a flexible line such as an electric cable supplying the probe.
  • the device according to the invention has a propulsion position in the casing and a measurement or intervention position and it includes means supporting said sealing members, said means being adapted on the one hand, to discover at least one opening. allowing the fluid to circulate all along the tube and the extension in said measurement or intervention position of the device and, on the other hand, to close said opening in said propulsion position.
  • said means comprise two elongated elements, one of which is fixed to the upper part of the extension and has at least two openings located on either side of the sealing members and the other of which is movable, has at least one opening located above sealing members and can be moved by sliding, under the effect of a traction exerted on said cable, or by a remote-controlled member from the surface, for example a motor, from a first position corresponding to the closing of said openings up to a second position which uncovers said openings.
  • said means comprise at the upper part of said extension a membrane delimiting an annular chamber of variable volume, this chamber being able to be connected to a source of auxiliary fluid under pressure to give said volume a value ensuring substantially the sealing and allowing propulsion by injection of fluid from the surface, said chamber can also be placed under vacuum to allow the flow of injection or production fluid in said casing, around said membrane and means for adjusting the pressure in said chamber.
  • the invention is more particularly applicable when the wells crossing the geological formation are deviated by an angle such that the probe cannot descend by gravity and, for example, by an angle of more than 40 ° relative to the vertical.
  • injection measurements can be made. Under these conditions, traction on the cable makes it possible to free the openings of the device according to the invention and the injected fluid can circulate.
  • the measurements are carried out during the injection phase, preferably by reassembling the whole of the equipment (the opening therefore being maintained).
  • the flow measurements for example, are made while the fluid is produced which will then be recovered on the surface.
  • the uncovered opening has a cross section substantially equal to the cross section between the casing and the extension so as to minimize the pressure drops.
  • the means supporting the sealing members include an anchoring on the flexible line at a point such that the length of said flexible line in the extension allows the opening to be discovered. It is, for example, at least equal to the length of the extension to which is added the length of the opening along the axis of the well.
  • the upper element sliding relative to the lower element may include locking systems, for example electromechanical, remote controlled from the surface, in order to maintain the opening in the closed position during pumping, during the descent. of the equipment, or maintaining the opening in the open position, when raising the equipment and during the production and measurement phase.
  • locking systems for example electromechanical, remote controlled from the surface
  • the means for adjusting the pressure in the variable volume chamber may include a compensation chamber in communication, on the one hand, with the interior of the casing and, on the other hand, with the source of auxiliary fluid.
  • the invention also relates to equipment usable for carrying out, during injection or fluid production operations, measurements or interventions in a well passing through a geological formation, this equipment comprising in combination a device as defined above and a remote controlled subsurface valve, through which said device can slide in the open position of this valve.
  • Said valve may define with the surface an airlock of a length equal to the length of the device.
  • FIG. 1 represents a well 1 equipped with a first casing 1a of internal diameter, for example equal to 40 cm, vertical from the surface 3 and which is deflected in its terminal part.
  • Another casing 1b for example 24 cm, contained in the first casing, descended into the deviated part of the well, the space between the two casings being cemented.
  • This tubing lb is extended by a third tubing 5 of about 18 cm in diameter which has holes 5a to recover the production of a horizontal drain 4.
  • a tubing support lc provides the link with the tubing lb and the tubing 5, while that a seal ld is made between the casing 5 and the production casing 2 of approximately 8 cm, at the end of which there is a restriction or "nogo" 40.
  • the extension 15 and the probe 8, for example, were pumped, that is to say pushed by a fluid (diesel for example) in the casing 2, thanks to a locomotive 16 from the surface.
  • a control cabin controls the handling, lifting and pumping of fluids.
  • a traction cable 6 (diameter for example 8 mm), driven by a winch 7, is connected to a probe support and to a standard type logging probe 8 (diameter 4.3 cm for example) which can be autonomous or connected by an electric cable to the surface, the latter can also be a towing cable.
  • the traction cable also supports the extension elements.
  • the logging probe 8 and its support are fixed either to the screwed elements of the "snubbing" or to the "coil tubing" (flexible tube wound on a coil) which constitute the extension 15, with a diameter close to that of the probe and of length, for example, between 100 and 500 meters and possibly connected to the surface by an electrical probe-surface connection provided either by a single connector at the probe, or by a multiplicity of connectors, each being arranged substantially in the vicinity of each element.
  • the propulsion means, all of the screwed elements, the probe support and the logging probe preferably have a diameter less than the opening diameter of the valve.
  • the device according to the invention illustrated in FIG. 2 At the upper end of the extension is the device according to the invention illustrated in FIG. 2, with the propulsion system 16 or locomotive comprising one or more sealing elements 17 (or cups) ensuring the sealing with the production tubing 2, this device being integral with cable 6.
  • FIGS 2 and 3 show an advantageous embodiment of the device according to the invention.
  • the upper element of the extension 15 has an extension 19 which can be screwed and of internal diameter substantially equal to that of the extension.
  • the lower part of this extension is pierced with at least a first lateral opening 20 possibly allowing the passage of the fluid through the extension; its upper part is also pierced with at least a second lateral opening 21 through which the fluid is discharged towards the surface.
  • Each of these openings is located on either side of the position of the locomotive 16. The role of these openings 20 and 21 can be reversed, if one works in injection.
  • the movable element or sliding sleeve 22 comes to cap the extension 19.
  • This sleeve has two openings 20a and 21a located on either side of the locomotive. It is integral with the cable 6 in its upper part and a pin 23 housed in a rotation wedge groove 24 allows only an axial displacement of the sliding jacket 22 when the cable 6 undergoes a traction from bottom to top.
  • the cable 6 has been secured on the surface to the sliding jacket 22 at a lashing point 27, after taking the precaution of leaving a little slack to allow the displacement of the sliding jacket.
  • the latter effectively comprises the sealing cups 17 of the locomotive 16. In the pumping position, it rests at 26 on the bottom stop 25 of the extension 19 of the extension and thereby obstructs the openings 20, 20a, 21 and 21a thus preventing any circulation of fluid.
  • a pull of the cable causes the jacket to rise up to a stop provided by the pin 23 and the openings are released. The fluid can then flow.
  • FIG. 3A illustrates another particularly advantageous embodiment in which the opening 20 through the element 19 remains permanently open, the sliding jacket 22 covering only the openings 21.
  • the section of the fluid inlet or outlet openings is preferably substantially equal to the section of the annular space between the casing 2 and the extension 15, so as to minimize the pressure drop.
  • the production tube comprises elements of decreasing diameter, for example three elements A, B, C (30, 31, 32) of respective diameters 0 A 3 ⁇ B and ⁇ C such that ⁇ A > ⁇ B > ⁇ C
  • FIG. 1 illustrates the artificial airlock 11 and more particularly the subsurface valve 33 arranged on the production line 2. This valve ensures safety and equilibrium airlock during the assembly and disassembly phase of the probe and of the extension and of the device according to the invention, and the putting in of the airlock, during the descent and ascent phase of all the equipment.
  • a manual remote control transmits energy from the surface to the valve 33, via either a hydraulic or gas-fired central 34 and a pipe 35, so as to open or close it at will during the various operating phases and especially so as to prevent any uncontrolled closure following an overpressure, which would cause the cable to break if the probe and extension were already engaged under the valve.
  • the valve is also self-closing, so as to comply with current safety standards.
  • a subsurface valve 33 is placed in advance on a casing of production 2 at a distance at least equal to the length between the wellhead and the end of the probe, or about 300 meters.
  • This valve is permanently open, with control for closing, or it can be permanently closed, with control for opening. We close the valve.
  • the airlock thus created is at atmospheric pressure. 0n successively introduces the measurement probe 8 attached to the cable 6, then the extension 15, element by element, and the propulsion system 16, 17 and 19 mounted on the device according to the invention.
  • An electrical connection is possibly established by means of a bottom connector.
  • the cable gland 36 is closed on the surface around the cable and the pressure is balanced on either side of the valve 33 and then it is opened by remote control from the surface.
  • the extension and the probe are then in the production drain 4.
  • the sliding jacket 22 is moved without touching the rest of the equipment, since the cable has a little slack inside the device .
  • This operation allows the fluid to flow through the holes 5a of the production area and from there to the surface and to pass through the openings 20 and 21 thus released, the device according to the invention. Under these conditions, it is possible to carry out measurements, for example of flow rate, using the production tubing which was used to move the probe and the extension.
  • the probe and extension can be moved by pushing or pulling on the cable.
  • the measurements can then be stationary, or made continuously during the movement, so as to determine a profile of drain flow.
  • the probe, extension and propulsion system assembly is reassembled without pistoning, since the sliding jacket is open and since the fluid can be transferred from the upper part to the lower part of the propulsion system.
  • the assembly being reassembled above the subsurface valve 33, the latter is closed and the airlock defined above is purged.
  • FIGS. 5 and 6 A variant of the device according to the invention which is particularly advantageous when the casing has variations in diameter is illustrated by FIGS. 5 and 6. It comprises an extension extension 19 fixed on the one hand to the cable 6 and on the other hand to the upper part of the extension.
  • This extension is laterally pierced with at least one hole 45 through which an auxiliary fluid (oil or viscous fat, or gas) flows which will be housed in an annular chamber of variable volume 46 and delimited by a polymeric membrane 47 and the extension.
  • This viscous fluid is circulated in a pipe 51 by a piston 48 driven by a motor 49 and which moves in a tank 50.
  • Another chamber 52 sends in the opposite direction via another piston 53 on which a compressed spring 54 is supported, a quantity of fluid which flows through another pipe 51 in relation to at least one hole 45 and which allows the balancing of the pressures between the fluid contained in the production casing 2 and the auxiliary fluid.
  • a piston control sends the viscous auxiliary fluid into the volume of the annular space delimited by the membrane, thus ensuring a seal against the production casing. Another mode of the propulsion system is therefore made up and the pumping of the equipment can proceed quite correctly.
  • variable volume of the ring finger 46 it suffices to partially empty the variable volume of the ring finger 46 so that the fluid can flow freely.
  • a diameter servo means coupled to the motor can advantageously be mounted downstream or upstream to pass any restrictions or variations in casing diameter likely to be encountered.
