Definitions

  • coiled tubing (alternately referred to as“coil tubing,” “endless tubing,” or“reeled tubing”) can be used to conduct various downhole operations and applications.
  • coiled tubing comprises a continuous length of flexible or semi-flexible pipe having a relatively consistent diameter along its full length that is unwound from an adjacent reel (spool) and progressively introduced into the wellbore.
  • coiled tubing is traditionally“pushed” from a surface location into the wellbore.
  • gravitational forces urge the coiled tubing against the inner wall of the wellbore, which results in the generation of frictional resistance as the coiled tubing rubs against the wellbore wall.
  • Advancing the coiled tubing further into the non-vertical section increases the frictional forces, which may eventually surpass the compressive limits of the coiled tubing and cause the coiled tubing to buckle.
  • Advancing the coiled tubing even further after buckling could end up locking the coiled tubing within the wellbore.
  • jointed pipe e.g., drill pipe, etc.
  • Jointed pipe must be snubbed under pressure to enter the wellbore, which creates significant risks for rig personnel and the surrounding environment.
  • Coil tubing is easier to snub in and out of a well due to consistent outside diameter.
  • FIG. 1 is a schematic diagram of an example well system that may employ one or more principles of the present disclosure.
  • FIG. 2 is an enlarged schematic view of the coiled tubing assembly of FIG. 1, according to one or more embodiments.
  • FIG. 3 is another enlarged schematic view of the coiled tubing assembly of FIG. 1, according to one or more additional embodiments.
  • FIG. 4 is another enlarged schematic view of the coiled tubing assembly of FIG. 1, according to one or more additional embodiments.
  • the present disclosure is related to coiled tubing intervention operations and, more particularly, to coiled tubing that incorporates one or more rotational devices that help reduce friction against wellbore walls and thereby mitigate buckling of the coiled tubing in non vertical sections of a wellbore.
  • the coiled tubing assembly may include coiled tubing conveyable into a wellbore, and a rotational device operatively coupled to the coiled tubing.
  • a rotatable tubing segment may be operatively coupled to the rotational device, and a bottom hole tool may be arranged at an end of the rotatable tubing segment opposite the rotational device.
  • FIG. 1 is a schematic diagram of an example well system 100 that may employ one or more principles of the present disclosure, according to one or more embodiments.
  • the well system 100 may include a wellbore 102 that extends from a surface location 104 and penetrates one or more subterranean formations 106.
  • the wellbore 102 may be drilled into the subterranean formation 106 using any suitable drilling technique and may extend in a substantially vertical direction away from the earth’s surface 104 over a vertical wellbore portion 108.
  • the vertical wellbore portion 108 may deviate from vertical relative to the Earth’s surface 104 and transition into a substantially non-vertical portion, such as a horizontal wellbore portion 110.
  • non-vertical refers to a section of the wellbore 102 that may be horizontal, slanted, deviated, or extending at any angle offset from vertical relative to the surface location 104. While not depicted in FIG. 1, in some embodiments, the horizontal wellbore portion 110 may comprise a lateral wellbore that extends from a parent wellbore (i.e., the vertical wellbore portion 108).
  • the wellbore 102 may be completed by cementing a string of casing 112 (or another type of wellbore liner) within the wellbore 102 along all or a portion thereof.
  • the casing 112 may be omitted from all or a portion of the wellbore 102 and the principles of the present disclosure may equally apply in an“open- hole” environment.

  • a reel 122 (also referred to as a“spool”) may also be mounted to the truck 118 and the coiled tubing 116 may be wound onto the reel 122 for storage or deployment.
  • the reel 122 may include various fixtures, plumbing, conduits, valves, etc. that enable the coiled tubing 116 to convey a variety of fluids downhole and into the wellbore 102 for various purposes.
  • the coiled tubing 116 may enter the wellbore 102 by passing through an injector 124. More particularly, the coiled tubing 116 may be unwound from the reel 122 and conveyed over a gooseneck guide 126, which guides the coiled tubing 116 into the injector 124.
  • the injector 124 may include hydraulic motors and counter-rotating chains designed to grip the exterior of the coiled tubing 116 and pull the coiled tubing 116 into the injector 124 and toward the wellbore 102. In some embodiments, the injector 124 may be configured to“push” the coiled tubing 116 into the wellbore 102 from the surface location 104.
  • a stripper 128 may be used to pack off between the coiled tubing 116 and the wellbore 102, and the injector 124 may further include or otherwise be coupled to a blowout preventer (BOP) 130 and a Christmas tree 132, which may regulate fluid pressure to safely inject the coiled tubing 116 downhole.

  • the coiled tubing 116 may form part of a coiled tubing assembly 136 conveyed into the wellbore 102 to undertake various downhole operations.
  • the coiled tubing assembly 136 may also include a bottom hole tool 138 (alternately referred to as a“bottom hole assembly”) arranged at or near the end of the coiled tubing 116.

  • the bottom hole tool 138 may comprise a drill bit used to extend the length (depth) of the wellbore 102.
  • the coiled tubing assembly 136 advances into the horizontal portion 110 of the wellbore 102, gravitational forces will urge the coiled tubing 116 to engage and slide (rub) against the inner wall of the wellbore 102, which creates friction at the interface.
  • the friction overcomes the forces advancing (pushing) the coiled tubing assembly 136 into the wellbore 102, the coiled tubing 116 may start to buckle at one or more points. At first, the coiled tubing 116 may deform into a sinusoidal wave within the wellbore 102.
  • the coiled tubing 116 may subsequently take on a more helical shape as the coiled tubing 116 assumes a“corkscrew” effect represented as three-dimensional buckling.

Abstract

L'invention concerne un ensemble colonne de production spiralée (136) comprenant une colonne de production spiralée (116) qui transporte dans un puits de forage, un dispositif de rotation (140) accouplé fonctionnellement à la colonne de production spiralée (116), un segment de colonne de production rotatif (144) accouplé fonctionnellement au dispositif de rotation (140), et un outil de fond de trou (138) disposé à une extrémité du segment de colonne de production rotatif (144) en regard du dispositif de rotation (140). Le dispositif de rotation (140) fait tourner le segment de colonne de production rotatif (144) par rapport à la colonne de production spiralée (116) pendant que la colonne de production spiralée, le segment de colonne de production rotatif (144) et l'outil de fond de trou (138) sont déplacés axialement le long du puits de forage.
