Definitions

  • the invention is related to the field of oil well drilling and re-entry. More particularly, the invention is related to providing an arrangement to facilitate the re- entry of lateral boreholes by coil tubing in a consistent, economical and reliable manner.
  • a Bowen Lebus knuckle joint or similar has traditionally been employed to provide the impetus for coil tubing to reenter lateral boreholes.
  • Bowen Lebus knuckle joints deflect under hydraulic pressure, the deflection being translated to the coil tubing and urging the coil tubing against the inner wall of the primary casing.
  • Providing the proper orientation of the coil tubing can be provided by some type of directional orienting tool run prior to the coil tubing (i.e., on an earlier workstring) or a simple trial and error technique.
  • U.S. Patent No. 5,373,906 to Braddick discloses an anchor or guide assembly connected with a work string and may include a drill string.
  • the guide assembly includes an internal tubular member to releasably connect with the working string.
  • a tube is within the internal tubular member.
  • the internal tubular member is releasably secured with an outer tubular member.
  • the internal tubular member is releasably secured with an anchor surface.
  • the work string is released from the internal tubular member to move relative to the guide assembly to extend the tube from the internal tubular member for performing various operations.
  • An orienting setting enables operations to be performed at various angles and directions from a location and, in this event, the outer tubular member includes a heel window and a face window and the internal tubular member has articulations to bend the internal tubular member or tube therein laterally to direct the tube laterally of a location when the work string is lowered. Braddick requires a significant number of cooperating devices, thus subjecting it to a high possibly of failure.
  • the present invention comprises an entry guide hung from coil tubing which entry guide includes an orientation anchor for rotating the guide assembly such that a diverter surface inside the housing of the guide assembly is appropriately angled to
  • the bottom hole assembly may be, and is preferably, run on the end of the coil tubing inside the housing of the guide assembly such that the entire operation desired may be accomplished in one trip downhole.
  • the coil tubing is withdrawn uphole until its end is within the guide assembly and then the guide assembly may be withdrawn from the borehole along with the coil tubing. This is facilitated by features on the end of the coil tubing which cannot pass through the top sub.
  • the arrangement of the invention alleviates all of the difficulty the prior art experiences with respect to multiple runs downhole and efficiency with respect to time required to complete the entry to the lateral.
  • FIGURE 1 is a quarter sectioned elevation view of the guide assembly of the invention
  • FIGURE 2 is an elevation view of the invention wherein the premachined window is visible;
  • FIGURE 3 is a quarter sectioned elevation view of the top sub of the invention.
  • housing 10 is quartered-sectioned to illustrate diverter plate 12 extending from the downhole edge of premachined window 14 and to illustrate the carrying assembly (mandrel) 16 of coil tubing 17 which prevents the removal of coil tubing through the top sub 18 of the guide assembly 20.
  • an orientation sub is endowed with an orientation lug slot 24 which is well illustrated in FIGURE 2.
  • Orientation sub 22 is also visible in FIGURE 1, but illustrates only half of orientation lug slot 24.
  • guide assembly 20 is run downhole at the end of coil tubing 17.
  • the guide assembly 20 Upon reaching the original whipstock packer, upon which the original whipstock rested to drill the lateral borehole, the guide assembly 20 is oriented by orientation lug slot 24 to turn guide assembly 20 until window 14 is coextensive with the lateral borehole.
  • Guide assembly 20 is freely rotatable on coil tubing 17 and no special movement of the assembly is required to provide the orientation necessary.
  • the plate 12 is angled toward the borehole to facilitate the entry of the coil tubing thereinto. The invention very simply and effectively expedites re-entry into the lateral with coil tubing.
  • Another benefit of the invention is that there is no special action required to facilitate coil tubing 17 moving into the preexisting lateral since tubing weight must merely be slacked off downhole until the end of the coil tubing impacts and kicks off of diverter 12.
  • the coil tubing 17 need merely be withdrawn uphole through top sub 18 until the carrying sub has returned to its running position within housing 10 of assembly 20. Upon obtaining this position, coil tubing 17 can no longer be removed uphole since feature 16 prevents the coil tubing from being removed from the top sub 18 of guide assembly 20. Further withdrawal of coil tubing uphole will disengage assembly 20 from the original whipstock packer and remove the assembly uphole.
  • top sub 18 of the invention is illustrated in a quarter section which renders visible a shear pin 32 in a safety release sleeve 34.
  • mandrel 36 cannot pass through the top section of top sub 18 because of the safety release sleeve 34, however in the event that guide assembly 20 becomes stuck in the original whipstock packer the shear pin 32 and safety release sleeve 34 enable the operator to retrieve the coil tubing and the bottom hole assembly without significant difficulty.
  • guide assembly 20 of the invention may be of any length required to completely envelop the bottom hole assembly and is frequently thirty feet in length.

Abstract

Un procédé et un appareil destiné à faciliter la rentrée d'un tube spiralé dans des puits latéraux évite les procédés de recherche à tâtonnement. Un guide suspendu au tube spiralé présente un mécanisme d'orientation tel que ledit guide s'oriente correctement avec le dispositif d'étanchéité du sifflet déviateur d'origine, fournissant ainsi une surface de déviation au tube spiralé dans la direction voulue du puits latéral.
