Definitions

  • the field of the invention is drilling with liner and more particularly a method to allow debris removal from a liner top before pulling out the bottom hole assembly (BHA) followed by running back in with a redressed BHA and latching the liner for resumption of drilling.
  • BHA bottom hole assembly
  • the steerable Drilling liner (SDL) system gives the operators the ability to accurately drill and log three-dimensional well profiles with a liner attached directly to the drill string. It simultaneously performs both drilling and casing operations.
  • the goal of SDL is not only to look for trip-time savings, but also for eliminate, or at least minimize the risks of the problems associated with both drilling and casing operations.
  • the drill cuttings are carried off from the bit with circulating fluid through the drill string that then takes the cuttings outside the liner.
  • the drill bit is run in tandem with a reamer shoe to enlarge the hole beyond the pilot hole made by the bit to a larger dimension so that the liner can advance as the drill bit extends the pilot hole.
  • the flow area of the annulus increases and is defined as the annular space between the drill string and the open hole.
  • a packer setting dog sub is used in the string. It features a series of spring loaded dogs that are initially held retracted when the drill string is latched into the liner for delivery. After finished drilling and release liner setting tool from its sleeve. By picking up on the run in string the required distance to allow the Packer Setting Dog Sub to clear the top of the polished bore receptacle (tieback extension). When the Dog Sub clears the liner top, the spring loaded dogs will expand. Slack off onto the liner top and apply the recommended set down weight.
  • this tool has an indicating mechanism that after the indicating mechanism is sheared, flow ports are opened between the drill string and annulus at the top of the packer. This allows circulation at the liner top to remove any drill cutting and/or debris from the top of the liner before pull the drilling BHA out of the hole.
  • an unlocking feature prevents the setting dogs from expanding during the initial time that the tool is raised above the top of the polished bore receptacle extension. But when the tool re-enters the extension one more time, the setting dogs are released from unlocking sleeve, such that the next time the tool is raised above the top of the extension, the dogs will expand.
  • This feature can help when a failure happened to the drilling BHA (inside string), pulling out of the hole with the inner drilling string is mandatory to change the failed tool, the unlocking mechanics which retract the spring loaded dogs gives the ability to run with the inside drilling BHA back inside the liner which lay down in the hole and attach the liner running tool one more time in its profile.
  • the Unlocking Rotating Indicating Packer Setting (URIPS) Dog Sub is designed to apply set-down weight to compression set liner top packers. It is placed between the liner running tool and the lift sub.
  • the unique unlocking feature prevents the setting dogs from expanding during the initial time that the tool is raised above the top of the extension. When the tool re- enters the extension, the setting dogs are released, such that the next time the tool is raised above the top of the extension, the dogs will expand. This feature can help prevent premature activation of the setting dogs, when checking for release of the liner running tool.
  • the spring loaded setting dogs After the spring loaded setting dogs have been activated they can be used to transfer set down weight from the drill string to the extension of the liner top packer. The drill string can be rotated during the application of set-down weight to help work the force down to the packer.

  • Liner running tool assembly allows for engagement with the liner using a latch feature such as when a replacement BHA has to be tagged into the liner left in the hole to accommodate bit replacement for example.
  • the assembly allows release from the liner with the running string being picked up but with a seal assembly still in a polished bore receptacle in the liner top. This way any surrounding cuttings near the liner top do not fall into the liner when picking up to be sure the BHA can freely come out of the liner.
  • a set down force after the initial pickup force is possible because the dogs have been retained in a retracted position during the initial picking up.

  • the BHA is picked up to confirm release from the liner while leaving the seal in the polished bore.

  • the drilling and reaming position continues until the BHA needs to be removed such as for replacement of the drill bit 13.
  • the method of doing this is to first release the liner running tools 5 from the liner setting sleeve 6 with a pick up force that still leaves the PBR-Pack off 15 in its associated seal bore liner setting sleeve 6. With the release of liner running tools 5 from the liner setting sleeve 6 confirmed, weight is set down then by the second raising motion allows the dogs cover sleeve 21 to move axially relative to the spring loaded dogs 22 so that pulling the spring loaded dogs 22 above the liner setting sleeve top 6 will extend them.
  • the ports 20 can have telescoping assemblies that are spring retracted and driven out by pressure that drives the fluid flow.
  • the openings can be skewed to add a spin to the cleaning flow while the telescoping members extend the reach of the cleaning flow.

Abstract

L'invention concerne un système de chemisage de forage orientable, caractérisé en ce que les outils de pose de chemisage qui soutiennent l'ensemble de fond de puits ont la capacité de se verrouiller de manière étanche dans le chemisage pour permettre la circulation à travers le trépan à mesure que le puits est réalisé et alésé. Avant de retirer un joint dans un réceptacle de forage poli à l'intérieur du chemisage, l'ensemble de fond est remonté pour confirmer la libération du chemisage, tout en laissant le joint dans le forage poli. Une seconde remontée permet aux taquets de s'étendre de sorte que le poids de dépôt ouvre un orifice de circulation afin de permettre le retrait de débris à proximité de la partie supérieure du chemisage en même temps que la poursuite de la circulation à travers l'ensemble de fond. Après retrait de l'ensemble de fond et abandon du chemisage dans le puits, l'ensemble de fond redressé avec les taquets sur ressorts retenus entre dans le chemisage et se verrouille de manière étanche au chemisage, de sorte que le forage puisse redémarrer.
