Definitions

  • the safety valve automatically shuts in the well. Closing of the safety valve is also effected whenever desired from a remote point. More specifically, a predetermined pressure drop in the tubing string connected to the apparatus and extending to the top of the well bore will cause the gas, or other fluid, pressure below the valve to automatically effect its closing.
  • the packer, safety valve, and all accessories can be lowered and removed through use of wire line equipment, such as an electric wire line, piano wire line, or a sand line, such equipment being lowered into the well casing through use of a known type of lubricator, such that the operations can take place under pressure and without the necessity for killing" the well.
  • wire line equipment such as an electric wire line, piano wire line, or a sand line
  • the well packer employed is capable of being anchored to the casing in packed-off condition against movement in both longitudinal directions and of being released and retrieved at the well casing through use of wire line operated equipment.

  • FIG. 31 is a longitudinal section, with parts shown in side elevation, of the upper portion of the retrieving tool in condition for retrieving the well packer and safety valve from the well casing;
  • FIGS. 32a, 32b, 32c, 32d, 32:: and 32f are quarter longitudinal sections through the well packer and safety valve, with the well packer parts retracted from the well casing and with the entire apparatus in condition for elevation through and from the wall casing, FIGS. 32b, 32c, 32d, 32c and 32f being lower continuations of FIGS. 32a, 32b, 32c, 32d and 32e, respectively.
  • FIGS. 1a and 1b a somewhat diagrammatic illustration of a portion of the apparatus embodying the invention is disclosed, with the parts in position for delivering gas from an underground reservoir (not shown) to a gas delivery line 10.
  • a well bore 11 extends downwardly from the ground surface to the location of the gas reservoir, there being a suitable master valve 12 at the top of a casing 20, the gas delivery line controlled by a valve 13, and a suitable head 14 communicating with a fluid pressure line 15, from which fluid under pressure can pass into a tubing string 16 connected to the head and extending downwardly in the well casing to operative connection with a safety valve 17 secured to a well packer 18 depending therefrom, which is illustrated as having been anchored in packed-off condition in the well casing 20.
  • the gas will flow from the reservoir into the packer l8 and out through ports 21, 22 in the safety valve above the packer into an annulus 23 surrounding the safety valve, flowing upwardly through the tubing-casing annulus 24 to the gas delivery line 10.
  • the well packer can be lowered in the well casing and anchored therein in packed-off condition against movement in both longitudinal directions. It includes a main or tubular body 25 (FIGS. 9d, 9e, 9]) the lower end of which is threadedly secured to a body latch sleeve 26 having a plurality of depending spyinglike arms 27 terminating in lateral outward directed latch fingers 28 adapted to be disposed under an inwardly directed circumferential shoulder or flange 29 integral with a thrust sleeve 30, the lower end of which is threadedly secured, belowthe latch fingers, to a lower thrust sleeve section 31 (FIG. 9]).
  • a retainer sleeve 32 is disposed within the upper portion of the extension 31, being held initially in a position closely behind the latch fingers 28 be a shear screw 33, in order to retain the latch fingers under the thrust sleeve shoulder 29.
  • the body latch sleeve 26 can only move to a limited distance downwardly along the thrust sleeve by engagement of its latch fingers with the upper end 34 of the thrust sleeve extension 31.
  • Upward force imposed upon the retainer sleeve 32 is transmitted from its lower flange 35 to a downwardly facing shoulder 36 on the extension sleeve 31, with which it is: in engagement when the shear screw 33 is intact.
  • the upper ends of the latch fingers 28 and their companion shoulder 29 are inclined in a downward and outward direction so that an upward pull taken on the body 25 and its latch sleeve 26 will tend to cam the latch fingers 28 laterally inwardly from engagement with the shoulder or flange 29.
  • Such action cannot occur so long as the retainer sleeve 32 is located behind the latch fingers.
  • Shearing of the screw 33 by imposing a downward force on the retainer sleeve 32 will enable the latter to shift downwardly to a position below the latch fingers 28, allowing the latter to shift laterally inwardly.
  • the extent of downward movement of the retainer sleeve 32 is limited by its engage ment with a split stop ring 37 confined within an internal groove 38 in the extension member 31.
  • Such downward movement is obtained as a result of engagement of a tool part, described hereinbelow, with an upwardly facing shoulder 39 in the retainer sleeve, the tool being guided into the sleeve by a downwardly tapering upper surface 40 on the retainer sleeve.
  • the upper end of the thrust sleeve 30 is threadedly secured to a lower abutment ring 41 slidably mounted on the periphery of the body 25 (FIG. 9e).
  • This abutment ring engages the lower end of a packing assembly 42, the upper end of which contacts an upper abutment ring 43 initially secured to the body 25 by a shear screw 44.
  • the packing assembly 42 includes a plurality of elastomer packing elements 45 engaging the upper and lower abutments 43, 41 and separated by metallic spacer sleeves 46. Relative movement of the upper and lower abutments 43, 41 toward each other will compress the packing elements 45 and expand them outwardly into firm sealing engagement with the wall of the well casing 20 and the periphery of the body 25.
  • the upper abutment 43 is threadedly secured to a lower expander 47 engaging initially retracted lower slips 48 adapted to be expanded outwardly upon relative'downward movement of the lower slips along the lower expander, by virtue of slida ble engagement of the inner downwardly and outwardly inclined inner surfaces 49 on the slips with companion tapered surfaces on the lower expander.
  • Relative separating move ment between the lower slips 48 and lower expander 47 will cause retraction of the lower slips because of opposed side tongues 50 on the lower slips engaging in companion grooves 51 in the lower expander (FIG. 11), the tongues and grooves being inclined in the same direction and to the same extent as the expander surfaces 49.
  • the upper ends of the lower slips 48 are formed as T-shaped heads 52 radially slidable in companion slots 53 in a slip ring 54.
  • the upper end of the slipring 54 has similar T-shaped slots 55 receiving the lower T-shaped heads 56 of a plurality of circumferentially spaced upper slips 57 engageable with an upper expander 58 initially. secured to the body by a shear screw 59 when the slips 48, 57 and packing assembly 42 are in retracted position (FIG. 9d).
  • the inner surfaces 60 of the slips 57 are inclined in an upward and outward direction, engaging companion surfaces in the upper expander 58, such that relative longitudinal movement toward each other between the upper expander and upper slips will effect radial outward expansion of the upper slips against the well casing 20.
  • the expander 58 has an extension sleeve 63 integral therewith and extending upwardly therefrom, which is slidable along the periphery of the body 25.
  • This extension sleeve is connected to a connector sleeve 64 extending upwardly from the expander 58 and encompassing the extension sleeve, the lower end of the connector sleeve engaging an upwardly facing shoulder 65 on the upper expander.
  • the upper end of the connector sleeve is threadedly secured to a connector sub 66 having an upper left-hand threaded box 67 threadedly secured to a valve body section 68 disposed therewithin.
  • the upper expander 58 although initially engaged by the lower end of the connector sleeve 64, is movable downwardly to a small extent relative to the latter by virtue of a one-way or ratchet interconnection 69 therebetween (FIGS. 9e, 13b).
  • the expander extension sleeve 63 has a plurality of upwardly facing ratchet teeth 70 on its periphery engaging companion downwardly facing ratchet teeth 71 on a split lockring 72 having external cam teeth 73 thereon engaging companion internal cam teeth 74 in the connector sleeve 64.
  • the extension sleeve 63 and upper expander 58 can move downwardly
