Definitions

  • the field of the invention is a compensating device that maintains a constant axial force on a borehole tool responsive to internal pressure in the tool created by fluid pumped through the compensating device and bound for the borehole tool.
  • What is provided by the invention is a system that can apply a constant loading force in either a downhole or uphole direction based on internal pressure.
  • the tool has the needed telescoping capability such that between opposed travel limits a predetermined force is applied in tension or compression to the attached borehole tool depending on the orientation of the compensation tool in the tubular string.
  • the fluid pressure that regulates the force applied to the borehole tool is the same fluid pressure that is applied to the borehole tool in the case of a milling tool.
  • the pressure exits nozzles and takes away cuttings.
  • the compensating device has a through passage that goes to the borehole tool. There is a lateral passage to a piston housing.
  • a net uphole force results from backpressure as a result of flow pumped through a section mill that mills in an uphole direction. If the vessel moves down the mill is just pushed away from the tubular being cut. If wave action takes the vessel up fluid is displaced back into the mandrel but the constant force up that is dependent on the existing backpressure in the tubing keeps a steady uphole force on the mill.
  • the tool can be reversed for applications that require a net down force during milling. Rotational locking between the mandrel and the outer housing can be used. Ports are sized to prevent damping responses.
  • FIG. 1 is a section view of the device in the lowermost position of the vessel
  • FIG. 2 is the view of FIG. 1 with the vessel having risen due to wave action
  • FIG. 3 is an alternative embodiment to FIG. 1 in the lowermost position of the vessel
  • FIG. 4 is the view of FIG. 3 in the uppermost position of the vessel
  • FIG. 5 is a section view through line 5 - 5 of FIG. 4 .
  • FIG. 1 there is a mandrel 10 having a passage 12 and lateral ports 14 .
  • An outer housing 16 surrounds the mandrel 10 and has ports 18 leading to a surrounding annular space 20 .
  • a vessel is schematically illustrated as V rides on the water and likely has a heave compensator on board to minimize the movement seen at connection 22 to the mandrel 10 .
  • Seals 24 and 26 are different diameters and define a variable volume chamber 28 between the outer housing 16 and the mandrel 10 . Pressure applied to passage 12 communicates with chamber 28 to create a net force in the direction of arrow 30 on the outer housing 16 .
  • Ports 18 communicate variable volume chamber 38 with the annular space 20 so that the mandrel 10 does not get liquid locked in housing 16 .
  • Seals 26 and 40 seal off chamber 38 from chamber 28 as well as sealing chamber 42 from chamber 38 .
  • Chamber 42 has the same pressure as in passage 12 and a series of keyways 44 between which are disposed keys 46 mounted to the mandrel 10 .
  • Mandrel 10 is rotationally locked to housing 16 using keyways 44 meshing with a key or keys 46 .
  • Mill M can be of a type that mills under a tensile force. The objective is to maintain a constant tensile force on the mill M during milling. Mill M also uses nozzles to clear milling debris and the pressure drop through those nozzles accounts for the back pressure in passage 12 during milling. With the opposed piston areas 32 on one hand and 34 and 36 on the other hand, the consistent back pressure from flow through passage 12 going to the nozzles of mill M results in a consistent tensile force applied to the mill M during milling. There can be some variation in the annulus 20 pressure but it should not materially affect the net force in the direction of arrow 30 on mill M. In most cases passage 12 pressure acting on area 48 will create a net force in the direction of arrow 30 on housing 16 slightly offset by pressure in annulus 20 acting on area 50 .
  • mandrel 10 and outer housing 16 can be changed so that pressure in passage 12 will result in a net downhole force on outer housing 16 if a mill M is used that operates with a compressive load against the piece being milled rather than a tensile force against the piece as shown in FIGS. 1 and 2 .
  • the mill M can be operated with rotating drill pipe or equivalent driving system connected to passage 12 on the uphole end and to the nozzles of the mill M on the downhole end.
  • the described device is able to maintain a constant force on a tool in a designated direction whose magnitude depends on the internal pressure pumped to the tool while compensating for vessel movements as the mill operates consistently with a required applied force.
  • the telescoping components have room to move relative, the movement of the vessel will be immaterial to the operation of the mill M.
  • torque can be transmitted through the tool as its telescoping components can be rotationally locked.
  • the device is simple in construction and needs just three seals for a force to be generated in an uphole direction. To generate a steady force in the downhole direction a single seal is needed.
  • the tool length can be configured to take into account the contemplated movement of the mandrel 10 attached to the vessel V so that the engagement with the travel stops is avoided.
  • FIGS. 1 and 2 result in a tensile force on the mill M
  • a resulting compressive force can result if the locations of ports 14 and 18 are swapped about the middle seal 26 .
  • the chambers 28 and 38 switch positions although the travel stops 32 and 52 remain in position.
  • the mill M can be simply connected at thread 22 and the vessel V connected to the outer housing 16 , essentially turning the tool of FIGS. 1 and 2 up side down and the result will still be a tensile force as is now shown.
  • FIGS. 3-5 show a simplified version of a mandrel 70 surrounded by an outer housing 72 .
  • the vessel V is connected at 74 and the mill M is connected at 76 .
  • Housing 72 has a passage 78 that continues as passage 80 to the mill M. Pressure in passages 78 and 80 creates pressure in variable volume chamber 82 due to the presence of seal 84 .
  • a force in the direction of mill M depicted by arrow 86 is generated for a mill that operates under a compressive force.
  • Housing 72 moves with the vessel V.
  • the FIG. 4 position is reached if the vessel V moves up so that surface 90 hits travel stop 88 on housing 72 although the length of housing 72 can be provided to avoid jarring loads on the mill M.
  • surfaces 92 and 94 should not contact when the vessel V moves down.
  • the mandrel 70 and housing 72 are rotationally locked in this case with matching non-round shapes in the form of hexagons. Other non-round shapes or splined arrangements are also contemplated as alternatives.
  • Variable volume chamber 96 has no seals near its lower end allowing fluid to enter or leave as the volume changes to avoid liquid locking of mandrel 70 .
