Definitions

  • the invention relates to a seal for a wellbore in which a fluid, for instance oil or gas, flows up.
  • blowout preventers are known from the prior art.
  • the term blowout preventer is used for various shut-off valves that are fitted directly over the wellbore in the case of a drilling operation.
  • Blowout preventers serve to prevent a fluid from flowing out of the wellbore. This is necessary, in particular, if the drill string is damaged or if the drilling operation encounters a pressurized zone.
  • the drill string While a drilling operation is being performed, the drill string extends through the blowout preventer. If, in this case, there is an outflow of the fluid that cannot be stopped by other means, a two-stage mechanism comes into effect in the blowout preventer. In a first stage, seals are activated, which seal off the outer space around the drill string. Should this not suffice to stop an outflow of the fluid, the drill string is severed inside the blowout preventer. Subsequently, it is possible to seal the blowout preventer by means of shut-off slide valves.
  • blowout preventer used it is questionable whether the dimensioning of the blowout preventer used is adequate for severing the drill string.
  • the invention is based on the idea of providing a drill string, at intervals to be defined, with a seal that unfolds if required, or of introducing a seal into a leaking wellbore in which a fluid such as, for instance, oil or gas, rises, in order to seal off the wellbore below the leak.
  • a first seal according to the invention for a wellbore having a wall has a pipe that can be introduced into the wellbore.
  • the pipe can be composed of one or more pipe segments.
  • the seal has at least one apron, which is composed of a fluid-tight material and which is fixed to the pipe in a fluid-tight manner. Consequently, no fluid can pass through between the pipe and the at least one apron.
  • the at least one apron can be introduced into the wellbore by means of the pipe.
  • the at least one apron can assume a state in which it is folded towards the pipe, or non-distended, and a state in which it is unfolded away from the pipe and towards the wall, or distended.
  • the pipe and the at least one apron are implemented in such a way that, in the state in which the at least one apron is folded towards the pipe, there is a gap between the at least one apron and the wall when the pipe is introduced into the wellbore. The fluid can then flow up through the gap between the at least one apron and the wall.
  • the seal has means that can be activated.
  • Activation of the means that can be activated results in the at least one apron being able to assume the state in which it is unfolded away from the pipe and towards the wall.
  • Activation of the means that can be activated after the pipe has been introduced into the wellbore, results in the at least one apron assuming the state in which it is unfolded away from the pipe and towards the wall, i.e. the at least one apron is brought from the state in which it is folded towards the pipe to the state in which it is unfolded away from the pipe and towards the wall.
  • Means that can be activated can be, for example, latches that can fasten or release the at least one apron.
  • a positive connection between the at least one apron and the wall is produced when the pipe has been introduced into the wellbore and the at least one apron has assumed the state in which it is unfolded away from the pipe and towards the wall. This connection fixes the seal within the wellbore and prevents the seal from sliding out of the wellbore.
  • the at least one apron has at least one fixing element.
  • the hardness of the at least one fixing element must exceed the hardness of the wall.
  • connection between the at least one apron and the wall is fluid-tight. Since, furthermore, the at least one apron is composed of a fluid-tight material and is fixed to the pipe in a fluid-tight manner, the gap is closed, such that no fluid can escape through the gap when the pipe has been introduced into the wellbore and the at least one apron assumes the state in which it is unfolded away from the pipe and towards the wall. The wellbore is thereby sealed off.
  • the at least one apron is preferably designed such that the connection between the at least one apron and the wall can be released by pulling on the pipe. By pulling on the pipe, therefore, the seal can be removed from the wellbore if required.
  • the change from the state in which the apron is folded towards the pipe to the state in which it is unfolded away from the pipe and towards the wall is effected passively, i.e. by means of a pressure applied to the at least one apron by the fluid rising in the wellbore.
  • the at least one apron when in the state in which it is folded towards the pipe, forms, together with the pipe, a gap-shaped pocket that can be entered by the rising fluid. This produces the pressure required for bringing the at least one apron into the state in which it is unfolded away from the pipe and towards the wall.
  • the activation of the means that can be activated then results in the pressure pressing the at least one apron against the wall, such that the gap is closed and the non-positive or positive connection between the at least one apron and the wall is produced.
  • the at least one apron is preferably designed in the form of a sack or umbrella.
  • a suitable material for the at least one apron is a flexible material that is resistant to the fluid, i.e. whose physical properties do not alter upon contact with the fluid.
  • the at least one apron can possibly also be composed of a textile material or of a metal braided fabric that, for the purpose of sealing, is coated with a suitable substance, possibly with a plastic, a plant-based polymer or a biopolymer.
  • suitable as material for the at least one apron are certain plastic films, or films composed of a plant-based polymer, and possibly biopolymers.
  • the film or the textile material can be provided possibly with a vapour-deposited metal coating as protection against destruction by the fluid.
  • the at least one membrane can be provided with reinforcing ribs, in order to enable the at least one membrane to function properly and to prevent damage.
  • the at least one apron can be composed of overlapping plastic or metal lamellae or of lamellae of textile material, as described above.
  • the at least one pipe is a drill string, to which the apron—or, as explained below, the capsule—is attached, in order to unfold if required and block the unhindered outflow of fluid.
  • the pipe can be an auxiliary linkage.
  • An auxiliary linkage refers to any pipe, other than the drill string, that serves to introduce the seal into the wellbore and subsequently divert the fluid.
  • an advantageous development of the invention has a plurality of aprons. These are disposed in succession along the pipe. At least one apron thereof is preferably provided with a passage for the fluid. This passage reduces the kinetic energy of the rising fluid. An apron that is located above, or behind, the apron provided with the passage can protect the latter from being destroyed.
  • the seal for the wellbore according to the invention has at least one capsule composed of a fluid-tight material.
  • the material of the capsule is plastically deformable, in order to ensure a stable anchoring of the seal.
  • Metal for instance, would be suitable.
  • the capsule can also be composed of a suitable unfoldable material, for instance one of the above-mentioned materials of the apron.
  • the capsule is realized in such a way that there is a gap between the capsule and the wall when the seal is introduced into the wellbore.
  • the seal has at least one propellant charge. Activation of the at least one propellant charge causes the capsule to be unfolded, or distended. Depending on the material selected, the capsule undergoes plastic deformation. As a result of this, the capsule is pressed against the wall, such that a non-positive and/or positive connection is produced between the capsule and the wall.
  • Suitable as a propellant charge are energy storage means such as, for example, compressed gases, solid propellant charges or pyrotechnic propellant charges.
  • the released energy unfolds or distends the capsule, such that it is pressed against the wall.
  • the connection between the capsule and the wall is positive and fluid-tight. Since the capsule is composed of a fluid-tight material, no fluid can escape through the gap when the seal has been introduced into the wellbore and the propellant charge has been activated. The wellbore is thereby sealed off.
  • the seal has a coupling.
  • the latter serves to connect a pipeline to the seal.
  • a passage extends through the seal, such that fluid can flow through the seal and be drawn off through the pipeline.
  • the seal can have a drive, instead of the at least one pipe to which it is attached and by means of which it has been introduced into the bore,.
  • This drive enables the seal to move within the fluid.
  • the drive is designed as a reaction drive, for example as a rocket engine.
  • a propeller engine can also be used as a drive.
  • the feed rate of the drive In order for the drive to be capable of introducing the seal into the wellbore against the upflowing fluid, the feed rate of the drive must exceed the flow velocity of the fluid in the wellbore.
  • the feed rate of the drive is to be understood as the velocity at which the drive progresses relative to the fluid rising in the wellbore.
  • a pipe can be used to introduce the seal into the wellbore.
  • the seal is attached to the pipe.
  • the connection between the seal and the pipe is fluid-tight.
  • the pipe can be the drill string or an auxiliary linkage.
  • the connection between the capsule and the wall is positive and/or non-positive and fluid-tight.
  • the outer surface of the capsule is shaped accordingly.
  • the outer surface of the capsule has at least one fixing element.
  • the hardness of the at least one fixing element must exceed the hardness of the wall, so that the at least one fixing element can penetrate the wall when, after the seal has been introduced into the wellbore, the capsule is distended and the outer surface of the capsule is pressed against the wall.
  • a positive connection is thereby produced between the capsule and the wall of the wellbore.
  • fixing elements are, for example, barbs.
  • the latter can have a fixing pin that is mounted displaceably relative to the capsule.
  • the at least one propellant charge can act directly upon the at least one fixing pin. Through activation of the at least one propellant charge, the at least one fixing pin can be pushed at least partially out of the capsule. If the seal is inside the wellbore and if the at least one fixing pin is pushed at least partially out of the capsule through activation of the at least one propellant charge, the at least one fixing pin can penetrate the wall.
  • the seal has at least one further propellant charge.
  • the capsule can be unfolded or distended and pressed against the wall.
  • the seal can be introduced ballistically into the wellbore.
  • the seal is accelerated before entry into the wellbore, i.e. it receives a kinetic energy.
  • This energy is suitable for introducing the seal into the wellbore up to a certain depth, where corresponding means that can be activated cause it to unfold.
  • FIG. 1A shows a seal for a wellbore with an apron in the state in which it is folded towards the pipe;
  • FIG. 1B shows a seal for a wellbore with an apron in the state in which it is unfolded away from the pipe and towards the wall;
  • FIG. 2 shows a seal for a wellbore with an apron in the state in which it is unfolded away from the pipe and towards the wall, with seals;
  • FIG. 3 shows a seal for a wellbore with reinforcing ribs and fixing elements
  • FIG. 4 shows a seal for a wellbore in the manner of a torpedo
  • FIG. 5 shows a displaceable fixing pin
  • FIG. 1A shows a seal, or closure, that has been introduced into a drill hole, or wellbore, 102 having a wall 104 .
  • the seal has an apron 106 .
  • the apron 106 is fastened to a pipe 112 and is in the state in which it is folded towards the pipe 112 .
  • Sensors 110 measure data such as, for instance, the movement of the pipe 112 , the position of the pipe 112 relative to the wall 104 , the hydrostatic pressure of the fluid surrounding the seal, the distance travelled by the seal within the wellbore 102 , or the flow velocity of the fluid.
  • the apron 106 is fixed, by means that can be activated, in the state in which it is folded towards the pipe 112 .
  • An activation of the means that can be activated, by the sensors 110 releases the apron 106 .
  • fluid flowing under the apron 106 causes the apron 106 to open.
  • FIG. 1B shows the apron 106 in the state in which it is unfolded away from the pipe 112 and towards the wall.
  • the pressure exerted upon the apron 106 by the rising fluid presses the apron 106 against the wall 104 . Consequently, a non-positive and/or positive and fluid-tight connection is produced between the apron 106 and the wall 104 .
  • the apron 106 thus closes the gap 108 .
  • seals 200 for example in the form of O-rings, can be attached to the apron 106 . This is represented as a whole in FIG. 2 and as a detail Z.
  • the pressure exerted upon the apron 106 by the rising fluid causes a positive and/or non-positive, fluid-tight connection between the seals 200 and the wall 104 .
  • reinforcing ribs 300 support the apron 106 .
  • the apron 106 which is not shown in FIG. 3 in order to better visualize the reinforcing ribs 300 , is positioned upstream of the reinforcing ribs so that the apron 106 , when in the unfolded state, is pressed against the reinforcing ribs 300 .
  • the structure of the reinforcing ribs 300 is similar to the rod assembly of an umbrella.
  • the reinforcing ribs 300 stabilize the apron 106 , centre the pipe 112 in the wellbore 102 , and additionally prevent damage to the apron 106 due to the pressure exerted by the fluid upon the apron 106 when in the state in which it is unfolded away from the pipe 112 and towards the wall 104 .
  • Seals 200 are advantageous, in particular, if the wall 104 of the wellbore 102 is composed of a hard material.
  • a soft wall 104 makes it possible to use the fixing elements 302 , shown in detail Z of FIG. 3 .
  • the fixing elements 302 are attached to the reinforcing ribs 300 and are composed of a hard material.
  • the material of the fixing elements 302 must be harder than the material of the wall 104 .
  • the fixing elements 302 have projections, for example in the form of barbs.
  • the apron 106 when in the state in which it is unfolded away from the pipe 112 and towards the wall 104 , is pressed against the wall 104 by the pressure exerted upon the apron 106 by the fluid, this results in the projections of the fixing elements 302 penetrating the wall 104 . A positive connection to the wall 104 is thereby produced.
  • the apron 106 can be opened in a step-wise manner.
  • the fixing elements 302 are pressed against the wall 104 , such that the projections of the fixing elements 302 penetrate the wall 104 and a positive connection is produced in respect of the wall 104 .
  • the gap 108 is closed by transforming the apron 106 from the state in which it is folded towards the pipe 112 to the state in which it is unfolded away from the pipe 112 and towards the wall 104 .
  • the fluid now flows through the pipe 112 .
  • valves present in the pipe 112 are closed.
  • the wellbore 102 is thereby completely sealed off.
  • the apron 106 is introduced into the wellbore 102 by means of the pipe 112 , in the preferred embodiment as an element of equipment of a drill string.
  • the seal of FIG. 4 is designed in the manner of a torpedo. In this case, a jet propulsion 400 generates sufficient thrust to introduce the seal into the wellbore 102 against the rising fluid.

  • the energy that is released as a result causes the capsule 401 to be unfolded, or distended, and pressed against the wall 104 .
  • the capsule 401 is provided with fixing elements 302 .
  • the hardness of the fixing elements 302 must exceed the hardness of the wall 104 of the wellbore 102 .
