Definitions

  • the present invention relates to a system and method for spooling coiled tubing for use in the oil and gas industry. More particularly, the present invention relates to a system and method for spooling coiled tubing from one spool to another at ground/deck level, thereby eliminating the need for working at heights.
  • spooling of coiled tubing from one coiled tubing reel to the other is normally performed at a height determined by the height of the equipment used, especially the coiled tubing reels themselves. This can be several meters high at a minimum.
  • the coiled tubing is transferred from one reel to the other on the high side of the coiled tubing drums. Personnel performing the work for this operation are required to work at these heights on either temporary platforms or specially designed equipment.
  • Spooling devices e.g., a levelwind
  • Spooling devices for correctly spooling the coiled tubing on and off the coiled tubing reels are required and one is provided as standard on most coiled tubing reel foundations. The larger the coiled tubing size, the more difficult the process becomes due to the coiled tubing residual bend forces involved and handling them at height.
  • the present invention by adding a spooling device (i.e., a second levelwind) to the back of a conventional coiled tubing reel, the present invention enables personnel to work at ground/deck level with the coiled tubing being spooled on/off the low side of the coiled tubing reels. Improved safety and working conditions are a direct result of eliminating the need for personnel to work at heights. Additional types of work can be performed, including cutting out or adding sections of coiled tubing, installing or removing spoolable connectors or performing welding work.
  • the portable spooling device can be moved to either coiled tubing drum, as required by the direction of coiled tubing movement.
  • a second levelwind may be added to both the supply reel and the service reel. Especially for the larger coiled tubing sizes (i.e., 2 inches and above), improved control of the spooling process without having to work at height is realized.
  • An alternative embodiment uses a single levelwind wherein the levelwind is adapted to rotate about the reel from a spooling position adjacent to ground level to an operational position for conventional operations running coiled tubing to the injector an on into a well.
  • Figure 1 is a schematic of the traditional way of spooling coiled tubing from one reel to another on the high side of the reels using the conventional levelwinds;
  • Figure 2 is a schematic of one embodiment of the present invention illustrating coiled tubing being transferred from one reel to the other on the low side of the reels;
  • Figure 3 is a more detailed schematic of one embodiment of the invention using a second levelwind mounted adjacent ground/deck level;
  • Figure 4 illustrates an elevating man rider system for access to the upper conventional levelwind
  • Figure 5 is a schematic of an alternative embodiment of the invention having a single levelwind rotatable between an operational position and a spooling position;
  • Figure 6 illustrates one embodiment for pivoting the elevating man rider system and the rotatable levelwind shown in Figure 5 .
  • the large diameter reels are required because they reduce the bending loads on the coiled tubing that would occur on smaller diameter reels.
  • due to the weight of such large diameter reels it is common to transport the reels either empty or only partially loaded with coiled tubing. Once on location, the entire length of coiled tubing needed for a particular well (or wells) may be spooled onto the service reel.
  • Several shipping or supply reels with shorter lengths e.g., 6000 feet of 2 7 / 8 inch tubing or less) may be required to provide the length of coiled tubing needed for a particular application.
  • the shipping reels are lighter weight due to the shorter lengths of coiled tubing stored on them.
  • Special connectors such as Duralink connectors from BJ Services Company, may be used to connect the various lengths of coiled tubing when spooling the coiled tubing off of the supply reels and onto the master service spool.
  • Such connectors are described in U.S. Patent Application Serial Number 10/394,392, filed March 21, 2003 , entitled “Composite Low Cycle Fatigue Coiled Tubing Connector,” the disclosure of which is incorporated herein by reference in its entirety.
  • Figure 1 illustrates the traditional way of spooling coiled tubing 10 from a shipping/supply reel 15 to a second reel 20, typically referred to as the service reel.
  • the spooling is typically accomplished by transferring the coiled tubing from one reel to another on the high side using the conventional levelwind mechanisms 25 associated with each reel. Due to the diameters of the reels, the coiled tubing is being transferred at a working height of 15 to 20 feet above ground level.
  • a second levelwind is used with at least service reel 20. More preferably, a second levelwind is used with each coiled tubing reel.
  • the second levelwinds 30 are located on the backside of the reels adjacent to the bottom of the reels.
  • the second levelwinds are inverted in their orientation relative to the conventional levelwinds attached to each reel.
  • the second inverted levelwinds are skid mounted (not shown) and may be attached to the frame of the reels by any suitable means such as pinning the second levelwind skid to the base skid of the reel.
  • the second levelwind may be attached to the reel on location thereby allowing lighter lifts of the reels and portable second levelwinds.
  • FIG 3 illustrates an exemplary preferred embodiment of the invention in more detail.
  • Reel 18 includes a self supporting base structure 35.
  • Coiled tubing 10 is spooled about reel 18.
  • reel 18 may be either a supply reel or a service reel.
  • Levelwind 25 is shown in the normal levelwind position for conventional operations running coiled tubing to the injector head (not shown).
  • Levelwind 25 is supported on telescoping pole 40.
  • Telescoping pole 40 allows extension of the levelwind when the wrapping diameter changes on the drum.
  • Pole 40 is attached to one end of arm 45, the other end of arm 45 extending to the axis of reel 18.
  • a comparable arm extends from the axis on the other side of reel 18 (not shown).
  • a portable second levelwind 30 is mounted behind the reel for spooling at ground/deck level.
  • the second levelwind is inverted (relative to levelwind 25) to facilitate diameter changes about the drum as the coiled tubing 10 is unwrapped from (or wrapped onto) the drum.
  • Levelwind 30 may be integral to base 35 or may be mounted to its own separate stand alone base (not shown). In the latter case, the base for levelwind 30 may be connected to reel base 35 by pinning or other suitable means.
  • FIG. 3 also illustrates an alternative safety feature of the present invention.
  • Elevating man rider apparatus 50 extends from pivotable arms 55 connected to the axis of reel 18. Elevating man rider apparatus 50 provides access to the upper conventional levelwind 25.
  • Apparatus 50 may be a basket or platform or other suitable structure that allows one or more personnel to work safely upon the upper levelwind as needed (e.g., maintenance on the levelwind, threading coiled tubing 10 through levelwind 25, etc.).
  • Apparatus 50 may be raised or lowered by pivoting arms 55 relative to the axis of the reel either hydraulically, electrically or pneumatically.
  • arms 55 may be raised or lowered by telescoping hydraulical cylinders 60 (shown in Figure 6 ) that are connected to support members on base 35.
  • Apparatus 50 may be raised by extending hydraulic cylinders 60, and lowered by retracting the cylinders.
  • Figure 4 illustrates the man rider apparatus in an elevated position.
  • Figure 4 also illustrates an alternative embodiment wherein pole 40 and arms 45 are inverted relative to levelwind 25, thereby providing a less obstructive work area for personnel in man rider apparatus 50.
  • the separate, second levelwind spooling system on the coiled tubing reel facilitates spooling of the coiled tubing from the shipping/supply reel to the service reel at ground level, thus eliminating working at heights.
  • personnel would typically be working at heights ranging from 11 ⁇ 2 to 3 feet above ground level.
  • maintenance work, welding, making connections and the like may be performed at a safer working height compared to traditional spooling operations.
  • the levelwind is a traditional levelwind mechanism which tracks on a double worm screw to feed coiled tubing across the width of the reel from flange to flange.
  • Telescopic pole 40 allows the levelwind mechanism to float up and down to accommodate varying heights as the coiled tubing is spooled and unspooled from the reel.
  • a single levelwind mechanism 25 may be used on the high side of the spool for running the coiled tubing in and out of a wellbore, and may also be used to transfer the tubing from one reel to another on the low side of the reel.
  • the levelwind 25 could be rotated relative to the reel from the high side to the back side of the reel (i.e., rotated approximately 180° about the axis of the reel as indicated by the depiction of levelwind 25 and arm 45). Arms 45 are rotated about the axis of the spool by suitable hydraulic, electric or pneumatic means.
  • the levelwind preferably works inverted so an operator would not have to disconnect the pipe when converting from injecting operations to spooling operations, or vice versa. Once the spooling has been finished, an operator could cut the coiled tubing 10 and then rotate the levelwind about the axis of the reel. In this way, the coiled tubing 10 would not have to be removed from the levelwind when converting from one operation to another.
  • Figure 6 illustrates one embodiment for rotating levelwind 25 between the operational position and the spooling position.
  • Telescoping hydraulic cylinders 65 are connected to arms 45 on one end and support members of base 35 on the other end.
  • the levelwind may be rotated between the operational and spooling positions by the retraction or extension of cylinders 65.
  • the present invention provides improved control over the coiled tubing, especially for larger sizes, allowing control of bending and pulling forces in a more suitable manner.
  • Coiled tubing that is spooled off of a reel retains a residual bend from the wrapping diameter of the drum that it was spooled on. Thus, the tubing does not come off the reel perfectly straight.
  • an operator In order to connect two ends of coiled tubing together, an operator must attempt to straighten the ends of the tubing to be joined together.
  • Coiled tubing connectors such as Duralink connectors, require additional equipment (e.g., jigs and clamps) to help align, manipulate and straighten the tubing ends for installation of such connectors. Using such equipment at ground level facilitates and expedites the installation of the connectors as well as improves the safety conditions surrounding the installation process.
