Definitions

  • the present disclosure relates to devices and method for perforating a subterranean formation.
  • Hydrocarbons such as oil and gas
  • Hydrocarbons are produced from cased wellbores intersecting one or more hydrocarbon reservoirs in a formation. These hydrocarbons flow into the wellbore through perforations in the cased wellbore.
  • Perforations are usually made using a perforating gun that is generally comprised of a steel tube “carrier,” a charge tube riding on the inside of the carrier, and with shaped charges positioned in the charge tube.
  • the gun is lowered into the wellbore on electric wireline, slickline, tubing, coiled tubing, or other conveyance device until it is adjacent to the hydrocarbon producing formation. Thereafter, a surface signal actuates a firing head associated with the perforating gun, which then detonates the shaped charges. Projectiles or jets formed by the explosion of the shaped charges penetrate the casing to thereby allow formation fluids to flow through the perforations and into a production string.
  • the present disclosure addresses the need for perforating guns that can provide high shot density.
  • the present disclosure provides a perforating gun having high shot density characteristics.
  • the perforating gun may include a carrier; a charge tube disposed inside the carrier; a plurality of sets of shaped charges axially distributed along the charge tube and the initiation tube, each shaped charge of the plurality of shaped charges being supported at an opening in the charge tube; and a plurality of detonator cords, each detonator cord of the plurality of detonator cords connecting to one shaped charge in each set of shaped charges.
  • FIG. 1 schematically illustrates an end view of a perforating gun according to one embodiment of the present disclosure
  • FIG. 2 schematically illustrates a sectional view of the FIG. 1 embodiment
  • FIG. 3 schematically illustrates a side view of a prior art perforating gun
  • FIG. 4 schematically illustrates an isometric view of a perforating gun according to one embodiment of the present disclosure.
  • FIG. 5 schematically illustrates a well completion system that includes a perforating tool according to the present disclosure.
  • the present disclosure relates to devices and methods for perforating a formation intersected by a wellbore.
  • the present disclosure is susceptible to embodiments of different forms. There are shown in the drawings, and herein will be described in detail, specific embodiments of the present disclosure with the understanding that the present disclosure is to be considered an exemplification of the principles of the disclosure, and is not intended to limit the disclosure to that illustrated and described herein.
  • the perforating gun 100 may include a carrier 102 that has a bore 103 for receiving a charge tube 104 and an initiation tube 106 .
  • the charge tube 104 and the initiation tube 106 each may include openings 108 and 110 , respectively, for supporting shaped charges 112 .
  • the carrier 102 , the charge tube 104 , and the initiation tube 106 may be formed as concentric tubulars made of a suitable material such as metal. However, it should be understood that other configurations, such as strips, may also be used.
  • the shaped charges 112 may be of convention design and include a case 116 having an open end 118 and a closed end 120 .
  • a post 122 may be formed at the closed end 120 and shaped to connect with a detonator cord 124 ( FIG. 1 ).
  • the charge tube opening 108 supports the shaped charge 112 at the open end 118 .
  • the open end 118 of the shaped charge 112 may be clipped, screwed, or otherwise fixed within the charge tube opening 108 .
  • the initiation tube opening 110 receives the shaped charge 112 at the closed end 120 and supports the connection between the post 122 and the detonator cord 124 ( FIG. 1 ).
  • the initiation tube opening 110 is sized to receive the post 122 , which may be affixed to the initiation tube 110 using features such as one or more bendable tabs or a charge clip.
  • each set has five shaped charges 112 circumferentially distributed along a plane 126 transverse to a longitudinal axis 128 of the perforating gun 100 or a component of the perforating gun 100 , e.g., the carrier 102 .
  • the angular positions of the shaped charges 112 of adjacent sets are phase-shifted. That is, the shaped charges 112 of adjacent sets point radially in different directions. This angular offset allows the space between two shaped charges 112 of one set to be partially occupied by a shaped charge 112 of an adjacent set.
  • Circumferentially offsetting the angular position of the shaped charges 112 in this manner increases the number of shaped charges 112 that can be packed within the internal volume of the perforating gun 100 .
  • greater or fewer sets of shaped charges 112 may be used at each plane 126 depending on the size and configuration of the perforating gun 100 .
  • a greater or fewer number of shaped charges 112 may be used within each set.
  • each shaped charge 112 of a given set is independently detonated.
  • each shaped charge 112 of the one set connects to a separate detonator cord 124 .
  • Each detonator cord 124 ballistically connects to one shaped charge 112 in each set of shaped charges 112 such that the energy released by the detonator cord 124 is transferred to and detonates the shaped charges 112 .
  • the detonator cords 124 may undulate or bend in order to accommodate the phase-shifts of successive shaped charges 112 .
  • the shaped charges 112 of a given set may be detonated by a common detonator cord 124 . More generally, any detonation mechanism that allows the shaped charges 112 to be shifted radially outward and away from the tool axis may be used.
  • conventional shaped charges 20 tend to be arranged closer to a center line or tool axis 22 of a perforating gun 24 . Positioning these shaped charges 20 close to the tool axis 22 allows a single detonator cord 26 to detonate all of the shaped charges 20 . This positioning reduces the circumferential area along which the shaped charges 20 can be disposed and thereby restricts the total number of shaped charges that can be packed into a given volume of perforating gun.
  • embodiments of the present disclosure position the shaped charges 108 further radially outward from the tool axis 128 ( FIG. 2 ), which increases the amount of circumferential area along which the shaped charges 112 can be distributed and arranged on a transverse plane.
  • the number of shaped charges 112 that can be packed into a given volume of a perforating gun 100 is increased.
  • the facility 30 can be a land-based or offshore rig adapted to drill, complete, or service the wellbore 12 .
  • the facility 30 can include known equipment and structures such as a platform 40 at the earth's surface 42 , a wellhead 44 , and casing 46 .
  • a work string 48 suspended within the well bore 12 is used to convey tooling into and out of the wellbore 12 .
  • the work string 48 can include coiled tubing 50 injected by a coiled tubing injector (not shown).
  • Other work strings can include tubing, drill pipe, wire line, slick line, or any other known conveyance means.
  • the work string 48 can include telemetry lines or other signal/power transmission mediums that establish one-way or two-way telemetric communication from the surface to a tool connected to an end of the work string 48 .
  • a suitable telemetry system (not shown) can be known types as mud pulse, electrical signals, acoustic, or other suitable systems.
  • a surface control unit e.g., a power source and/or firing panel
  • a perforating gun 100 is coupled to an end of the work string 48 .
  • the perforating gun 100 may include one or more detonators 60 that detonate the detonator cords 124 ( FIG. 1 ).
  • the perforating gun 100 may be conveyed into the wellbore 12 and positioned at a desired depth. Thereafter, a suitable signal is transmitted to activate the detonator(s) 60 , which then fires the perforating gun 100 .
  • the projectiles formed by the shaped charges 112 may perform any number of functions including, but not limited to, perforating the formation or a wellbore tubular such as casing or liner. These projectiles may also be used to sever a wellbore tubular so that the tubular may be extracted from the wellbore 12 .
