Definitions

  • the present invention relates to coiled tubing injectors. More particularly, the present invention relates to a gripping assembly for use in a coiled tubing injector.
  • a continuous length of coiled tubing, carried on a reel is stabbed into a coiled tubing injector positioned at a desired location over a wellbore to be drilled or, in certain cases, over an existing wellbore to conduct reentering objects, etc.
  • a coiled tubing injector generally comprises a pair of opposed, endless drive chains arranged in a common plane. Such chains are made up of links, rollers and gripping assemblies.

  • Carrier 14 comprises a carrier body 24 having a base surface 26 and first, second and third ears 28, 30 and 32 extending from base 24 in the direction away from base surface 26. Ears 28, 30 and 32 have registering bores, one of which is shown as 34 through which a roller pin 36 extends, rollers 22A and 22B being mounted on roller pin 36 between ears 32, 30 and 28, respectively.
  • the body 24 also has through bores 38 and 40 through which link pins 42 (see Fig. 1 ) extend.

  • First and second, radially inwardly projecting spaced keyways 48 and 50 are formed between the cylindrical wall segments. Each keyway is an open communication with a slot, one of which slot 52 is formed between base surface 26 and a ledge 54, forming part of top surface 56 of formation 44. It will be understood that there is an identical keyway and slot formed diametrically opposite keyway 48 and slot 52.

  • Shoe 12, like carrier 14, is generally formed by casting, forging, machining or the like, is monolithic in construction and comprises a receiving formation 80, having circumferentially spaced, radially inwardly facing circumferentially extending wall segments 82 and 84.
  • receiving formation 80 like formation 56 is generally circular when viewed in plan view and the cylindrical wall segments 82, 84 of the receiving formation 80 are generally concentric with the cylindrical, radially outwardly facing wall segments on projecting formation 44.

  • the keys 86 and 88 are complimentary in shape to the keyways 48 and 50 in projecting formation 44.
  • Receiving formation 80 like projecting formation 44 is formed in a body 89, which has a top surface 90 in generally surrounding relationship to receiving formation 80.
  • body 89 has spaced base sections 92 and 94, channel 70 being formed therebetween.
  • detent assembly 73 having detent ball 74 is received in blind bore 70 of base section 92, a similar detent assembly being received in base section 94 diametrically opposite base section 92.
  • shoe 12 In connecting shoe 12 to carrier 14, shoe 12 would be moved along an imaginary axis shown as A, generally perpendicular to surface 56 of projecting formation 44 and surface 98 of receiving formation 80, the cylindrical wall segments of the receiving and projecting formations 80, 44 being concentric around axis A.
  • gripping shoe 12 instead of the position shown in Fig. 2, gripping shoe 12 would be rotated relative to carrier 14, such that keys 86 and 88 would be in register with the keyways 50 and 52 in receiving formation 44.
  • key 86 would be in register with keyway 50, while key 88 would be in register with keyway 52.
  • shoe 12 can be rotated relative to carrier 14, such that the keys 86, 88 will be forced into the slots, one of which is shown as 52 on projecting formation 44. Rotation is continued until the detent balls 74 on the detent assemblies 73 engage detent holes 64 and 66. At this point, shoe 12 and carrier 14 are releasably locked together preventing relative rotation of shoe 12 and carrier 14 without the application of relative rotational force between shoe 12 and carrier 14.
  • FIG. 5-7 there is shown another embodiment of the present invention.
  • the embodiment of Figs. 5-7 comprises a gripper shoe 100 and a gripping carrier portion 102.
  • carrier portion 102 With respect to carrier portion 102, only the body portion 104 in which is formed a receiving formation 106 is shown.
  • Receiving formation 106 has circumferentially space, radially inwardly facing cylindrical wall segments, only one of which is shown as 108, the other wall segment being diametrically opposite wall segment 108.
  • Formed in receiving formation 106 are diametrically opposed, circumferentially spaced ledges 110 and 12; each of which has a bore, only one of which is shown as 114 in ledge 112.
  • Also formed in receiving formation 106 are diametrically opposed keyways 116 and 118.
  • a shoulder or stop 120 is adjacent ledge 110, while a similar shoulder 122 is adjacent ledge 112.
  • Shoe 100 has a projecting formation shown generally as 140.
  • formation 140 Hke receiving formation 106
  • Projecting formation 140 projects upward from body 142, and has circumferentially spaced cylindrical, radially outwardly facing wall segments 144 and 146.
  • Body 142 has a base surface 148.
  • Projecting radially outwardly from receiving formation 140 are keys 150 and 152, each of which has a hole 154 and 156, respectively. Open slots 158 and 160 are formed between base surface 148 and the underside of keys 150 and 152. Referring now to Fig.
  • FIG. 8 there is shown still another embodiment of the present invention.
  • the embodiment shown in Fig. 8 is similar to that shown in Figs. 5-7 with the exception that there are no stop shoulders such as shoulders 120 and 122, meaning that when formation 106A and projecting formation 140A are connected as in the manner described with respect to the embodiment shown in Figs. 5-7, carrier 102A and shoe 100A are free to rotate, unless stopped by use of anti-rotation pins as discussed above.
  • Fig. 9 is shown still another embodiment of the present invention.
  • the embodiment shown in Fig. 9 comprises a carrier 160, having a receiving formation 162 formed in a body 164.
  • Shoe 166 has a projecting formation 168 formed on the body 170.
  • both the receiving formation 162 and the projecting formation 168 have spaced, cylindrical wall segments which are relatively radially inwardly and outwardly facing, the wall segments being generally diametrically opposed to one another.
  • Formed in receiving formation 162 between the cylindrical wall segments are tapered ramps 172 and 174, ramp 172 having a blind bore 176, there being a similar blind bore in ramp 174.
  • Keys 180 and 182 are tapered on their underside with an angle complimentary to the taper of the ramps 172 and 174. It will be appreciated that when projecting formation 168 is received in receiving formation 176, and there is sufficient relative rotation, the keys 180 and 182 will ride up the ramps 172 and 174, respectively until surface 164A on carrier body 161 is co-plantar with the top surface 168A on projecting formation 168. At this point, anti-rotation pins can be inserted to prevent counter rotation of carrier 160 and shoe 166. As in the embodiment shown in Figs.
  • engagement of the shoe with the carrier is accomplished by relative movement of the receiving formation and the projecting formation, along an imaginary axis concentric to the cylindrical wall segments, whether outwardly or inwardly radially facing, on the receiving and projecting formations followed by rotation to engage latching formations which prevent relative axial movement between the shoe and the carrier.

Abstract

L'invention concerne un ensemble bloc de préhension s'utilisant dans un injecteur de tube d'intervention enroulé et qui comporte un support, conçu pour être relié à la chaîne d'un injecteur de tube d'intervention enroulé et un sabot, destiné à entrer en contact avec le tube d'intervention enroulé traversant l'injecteur de tube d'intervention enroulé. Le sabot et le support comportent respectivement des éléments saillants et des éléments de réception, chacun des éléments saillants présentant une configuration généralement circulaire en vue en plan. L'élément saillant et l'élément de réception entrent en prise par un déplacement axial relatif du support et du sabot suivant un axe imaginaire, perpendiculaire aux éléments. Les éléments peuvent tourner au moins partiellement l'un par rapport à l'autre quand l'élément saillant est reçu dans l'élément de réception. Un élément de blocage libérable sélectivement empêche la contre-rotation de l'élément saillant et de l'élément de réception quand l'élément saillant est reçu dans l'élément de réception, et une valeur prédéterminée de rotation entre les deux éléments permet à un verrou de prévenir un déplacement axial correspondant entre l'élément saillant et l'élément de réception.
