Definitions

  • Annular blowout preventers have long been used to assist in controlling pressure within well bores and have generally includes a body with an inner rim, and an outer rim, an upper plate ring secured within the outer rim with a central bore extending through the body and plate ring with an annular packer recess facing onto the central bore with the plate ring forming the upper surface of the packer recess, a packer in the recess and a means to actuate the packer to closed position either on itself or on a tubular member extending through the central bore.
  • Various means of securing the plate ring within the outer body rim have-been used, such as a threaded connection as shown in U.S. Patent No. 4,310,139; dogs which are actuated by a piston-operated cam into locking engagement with the body rim as shown in U.S. Patent No. 3,741,295.
  • the present invention relates to an improved annular blowout preventer having a body with inner and outer upstanding rims, an upper plate ring having means for securing it to the upper portion of the outer rim which securing means is operable manually or responsive to fluid pressure, a central bore through the body and upper plate ring, a packer recess surrounding and opening onto said central bore, a resilient packer in said packer recess, and pressure responsive means for moving the packer to closed position.
  • An object of the present invention is to provide an improved annular blowout preventer with a top plate ring which is easily and quickly secured remotely and also manually.
  • Annular blowout preventer 10 includes body 12 which has lower flange 14 with upstanding inner rim 16 and upstanding outer rim 18 which is space outward from rim 16 and extends above the upper end of rim 16. Securing means 20 secures upper plate ring 22 within the upper end of outer rim 18 as hereinafter described. Central bore 24 extends through body 12 and plate ring 22.
  • Inner ring 26 is secured to inner rim 16 as shown and outer ring 28 is held in position between shoulder 30 on outer rim 18 and snap ring 32 positioned in groove 34 on the interior of outer rim 18.
  • Inner ring 26 and outer ring 28 are spaced apart to receive tube 38 which connects piston 40 in chamber 42 below rings 26 and 28 to actuating plate 44 above rings 26 and 28.
  • Packer 46 is positioned in packer recess 48 between surface 50 of upper plate ring 22 and the upper surface 52 of inner ring 26.
  • Packer 46 includes resilient annulus 54 with suitable support inserts 56 embedded therein and is surrounded by outer resilient annulus 58 which is engaged by actuating plate 44 as shown.
  • split ring 64 is normally in its unlocked or retracted position as shown in FIGURE 3 and has inner cam surfaces 66 which are engaged by surfaces 68 on the exterior of sleeve piston 70 so that when piston 70 is moved downward split ring 64 is cammed or wedged outward into its locking position shown in FIGURE 4.
  • piston 70 is moved upward split ring 64 retracts to its unlocked position.
  • the locked position of split ring 64 with its lower end engaging upwardly facing shoulder 72 locks or secures upper plate ring 22 to outer rim 18 and thus provides securing means 20 previously mentioned.
  • Sleeve Piston 70 is movably positioned within split ring 64 and in surrounding relation to surface 78 on upper plate ring 22 and seal ring 80 which is secured to upper plate ring 22 by suitable fastening means such as cap screws 82.
  • Chamber 84 between the interior of sleeve piston 70 and surface 86 on upper plate ring 22 is supplied with suitable pressure fluid, such as air. above and below piston seal 88 by ports 90 and 92.
  • suitable recessed fittings 90 are provided at the outer openings of ports 90 and 92.
  • air or hydraulic fluid supplied to port 90 causes piston 70 to move downward to lock securing means 20 and air supplied to port 92 causes sleeve piston 70 to move upward to unlock securing means 20.
  • Screws 96 thread through rim 18 and are adapted to engage in groove 98 in the exterior of sleeve piston 70 to prevent inadvertent release of securing means 20 from its locked position.
  • Tapped holes 100 in the upper surface of sleeve piston 70 are provided to allow suitable devices such as lifting eyes 102 to provide for-the manual or mechanical lifting of sleeve piston 70 for the manual release of securing means 20. Also exerting a mechanical force on the upper surface of piston 70 moves it downward to lock securing means 20.
  • securing means may be operated remotely by use of a pressure fluid or manually by exerting a mechanical force directly applied to piston 70 to move it in the desired direction.
  • Tapped holes 104 in the upper surface of upper plate ring 22 are provided to receive lifting eyes (not shown) for ease in removing and replacing upper plate ring 22.
