Definitions

  • the present invention relates to a new construction for a device for conveying a pressure pulse to activate a fluid pressure operable equipment in a pipe, such as a well, as defined in the preamble of the appended claim 1 .
  • the invention is concerned with a construction which is capable of supporting operation of downhole equipment which is hydraulically operated.
  • a manner of limiting the problem is to couple the equipment via a hydraulic control line (a conductor) which is disposed outside the existing pipe wherein the plug is mounted.
  • a hydraulic control line a conductor
  • Such a control lines are routed upwards and through the wellhead-installation and further up to the rig, such that it can be subject to pressure directly from the rig, and as a consequence one is still able to operate the equipment despite an accumulation of mud over the plug in the pipe.
  • a known solution is to use an kind of accumulator for introducing clean liquid into the well.
  • Such a solution is described in Norwegian patent application no. 2008 0452.
  • an accumulator which includes a limited volume for supplying the equipment with clean liquid for operating it.
  • the solution pursuant to the present invention includes installing a flexible diffusion-free membrane, for example fabricated from a rubber material, in its own housing/sleeve-section of the pipe).
  • the device pursuant to the present invention is characterized in that the pipe includes a flexible membrane which isolates a fluid F 1 in the fluid-conveying pipe from a fluid F 2 in another canal which is in fluidic communication with the equipment, wherein the membrane, on account of its elasticity, conveys pressure changes (pressure pulses) in the fluid P 1 in the pipe to the fluid P 2 in the other canal.
  • the beneficial implementations appear in the dependent claims 2 to 9 .
  • a piston which moves axial in a longitudinal direction will be limited in area which can be affected, whereas a bellows which moves radially is capable of providing an enormous area which can be affected. This area is limited only by the length of the bellow.
  • FIG. 1 is an illustration of a pipe which is installed within a borehole in, for example, a hydrocarbon-bearing formation, wherein the inventive device is employed.
  • FIGS. 2 and 3 are illustrations of the details of the inventive construction 10 in two positions, in that it is disposed a distance upstream in respect of down-hole equipment 20 which is be operated hydraulically pursuant to the present invention.
  • FIG. 3B is an illustration of an elongate cross-section of a hole which is arranged in a radial direction through the pipe wall.
  • FIGS. 4 and 5 are illustrations of an enlarged portion of FIG. 2 and FIG. 3 , and illustrates the hydraulic canal 30 through the pipe wall and which couples the pressure pulse device 10 with the equipment 20 .
  • FIGS. 1 and 2 provide illustrations of a pipe 12 which is deployed in a borehole 14 in a formation 16 .
  • a pipe section 18 is installed at a lowest portion of the pipe 12 with a seat accommodating a plug 22 .
  • the plug 22 is used, for example, initially for testing and checking that the interior of the pipe is sufficient non-leaky under pressure, and will function as intended during production of hydrocarbons from the formation 16 .
  • the device 10 is positioned a distance up over the plug 20 , and the plug 20 and device 10 are mutually coupled via a canal 30 which extends axially along and through the wall of the pipe between these two regions.
  • the device includes a perforated pipe section 27 which is installed into the pipe 12 .
  • a hollow volume or chamber 26 is defined between the outer wall 21 of the section and the inner wall of the pipe 12 .
  • a sleeve-shaped elastic bellows or membrane 24 Surrounding the pipe section 25 is threaded a sleeve-shaped elastic bellows or membrane 24 , and uppermost at 31 and lowermost at 33 is attached in the solid material of the pipe section 25 .
  • the bellows 24 can subsequently bulge out from a position where in lies bonded onto the pipe section's outer wall 21 and to an extent it bulges out and lies against the inner wall 13 .
  • a ring-shaped chamber 26 coupled with a drilled canal 30 which extends through the pipe wall downwardly to the release mechanism (not especially shown here) which is used to explode the plug away.
  • FIG. 2 illustrates the situation where the pressure P 1 is higher than the pressure P 2 (P 1 >P 2 ) such that the membrane bulges out.
  • FIG. 3 is an illustration of a situation wherein the pressure P 2 is higher or equal to the pressure P 1 and the membrane lies in a wavy manner against the outer wall 21 .
  • a release mechanism which removes the plug is adapted such that it counts a number of pulses, wherein the pulses are generated by increasing and decreasing the fluid pressure P 1 , and wherein the plug is exploded away at a predetermined number of pulses.
  • the pressure-sensitive valve can be set, or be set up, either to read the signals electronically with help of a pressure transmitter, or it can be a purely mechanical system which reads pressure pulses for opening the valve at a predetermined number of pressure pulses.
  • the technology can be used to operate down-borehole equipment which is hydraulically operated, and requires clean liquid for operating correctly.
  • Examples of such equipment can be detonation systems for removable (disappearing) plugs, sliding sleeves, hydraulically operated ball valves and hydraulically-operated flapper valves. These are only some few example of equipment with which this new technological solution can be utilized.
  • the hydraulically operated system can for example be a layer-divided plug 22 fabricated from glass. In whatever manner it is removed or smashed is not specifically shown in the Figures.
  • the pressure-pulse controlled apparatus can include A device 39 which is operable the count the number of pulses, and when it has counted a correct number, the mechanism is activated and releases an explosive mechanism.
  • a device 39 which is operable the count the number of pulses, and when it has counted a correct number, the mechanism is activated and releases an explosive mechanism.
  • This can, for example, mean that an axially-disposed piston 38 in the pipe wall is pushed downwardly with large force and slides a horizontally-orientated smashing piston in a radial direction and into the plug 22 which thereby can be smashed.
  • the plug can be fabricated from ceramics materials which can be smashed or from glass which is adapted for this purpose.
  • the bored out region is of course widest out towards the wall surfaces, namely the form of holes 52 to 54 shown in the diagrams are such that the outermost form respectively cone-shaped form or conically formed holes, or substantially of trumpet-form. These borings can have other cross-sections than circular.
  • An advantage with this form of hole is that each hole is not so easily blocked permanently by slime and particles.
  • a particle 60 in the pipe fluid which may bind and block the entrance to the bored hole 56 , when the fluid F 1 streams in a direction of the arrow P 2 , will simply loosen and be pushed back again when the fluid pressure P 2 exceeds the fluid pressure P 1 and the fluid F 2 streams back. The particle 60 will then be easier to be loosened by the back streaming.
  • a breaking plate or several
  • brushing disks which are arranged to break or burst when, for example, 10 Bar pressure difference between the pressure in the clean fluid behind the flexible material and the liquid in the well pipe arising, further ensuring against there arising a pressure difference between the two liquids.
  • the flexible membrane will also always bring about that identical pressures arise on both sides and return to its original form after a pressure excursion.
  • the burst disk 62 is adapted for creating fluidic communication in an event that an excessive pressure is developed on the back side (P 2 ) of the bellows, namely when the pressure is not the same as the pressure P 1 within the pipe (tubing).
  • the boring for the break disk can, as a point of reference, be placed anywhere, as long as it stands positioned such that it separates fluid between the tubing and back side of the bellows and creates a communication path between them when it bursts.
  • the burst disk 62 will also provide an eventual operation of the equipment which is to be controlled by later re-filling with liquid when the clean liquid behind the membrane is consumed, wherein the membrane is pre set towards the walls in its respective housing, so that a pressure difference arises between the well pipe (P 1 ) and the back side (P 2 ) of the membrane, whereafter the burst disk will break and liquid from the well will thereafter pour into the system.
