Definitions

  • This disclosure relates generally to methods and apparatus for acquiring cores from subterranean formations. More particularly, this disclosure relates to methods and apparatus for mitigating the effects of core jamming by utilizing a telescoping core barrel to acquire a core from a subterranean formation.
  • Formation coring is a well-known process for obtaining a sample of a subterranean formation for analysis.
  • a specialized drilling assembly is used to obtain a cylindrical sample of material, or "core,” from the formation so that the core can be brought to the surface.
  • the core can be analyzed to reveal formation data such as permeability, porosity, and other formation properties that provide information as to the type of formation being drilled and/or the types of fluids contained within the formation.
  • a core As a core is being drilled, it is received within an elongated tubular receptacle, known as a barrel. As the core moves into the barrel it can become stuck, or “jammed,” in the barrel, and prevent additional core from moving into the barrel. Once a jam occurs, the drilled core is subjected to increased compressive loads until the coring operation is stopped. Often, the increased compressive loads can damage the core before the coring operation can be stopped. Thus, in many instances, a core jam can result in an insufficient length of core being obtained and/or damage the core that can compromise the desired analysis. Therefore, in conventional coring operations, when a core jam is detected, the coring operation is halted and the tools are brought back to the surface. This can be especially costly in deep wells where it may take several hours to retrieve the coring tools from the bottom of the well.
  • a coring assembly comprises a shoe and a tubular body having a first end coupled to the shoe.
  • An inner sleeve is releasably coupled to the shoe and has a first end disposed within the shoe and a second end that is slidably engaged with the tubular body.
  • a middle sleeve is slidably engaged with the tubular body and releasably coupled to the shoe. At least a portion of the middle sleeve is disposed within an annulus defined by the inner sleeve and the tubular body.
  • Figure 1 is partial sectional view of an exemplary coring assembly including a telescoping core barrel.
  • Figure 1 A is a detailed view of the upper end of the coring assembly of Figure 1.

  • Figure 4 is a partial sectional view of the coring assembly of Figure 1 shown in a third position where the inner sleeve and the middle sleeve are moved axially relative to the shoe.
  • first and second features are formed in direct contact
  • additional features may be formed interposing the first and second features, such that the first and second features may not be in direct contact.
  • exemplary embodiments presented below may be combined in any combination of ways, i.e., any element from one exemplary embodiment may be used in any other exemplary embodiment, without departing from the scope of the disclosure.
  • coring assembly 10 includes an inner barrel assembly 12 that is disposed within an outer barrel 14 and a coring bit 16, which is coupled to the outer barrel 14.
  • the outer barrel 14 and coring bit are disposed in a wellbore and rotated so that the coring bit 16 cuts a core of material from the formation.
  • the inner barrel assembly 12 is not rotationally coupled to the outer barrel 14 or coring bit 16 so that the inner barrel assembly 12 can remain rotationally stationary as the core is being drilled.
  • the inner barrel assembly 12 includes a shoe assembly 18, a tubular body 20, an inner sleeve 22, and a middle sleeve 24.
  • the inner sleeve 22 and middle sleeve 24 are releasably coupled to the shoe assembly 18 and are operable to telescope relative to each other and the tubular body 20 once released from the shoe assembly 18.
  • the telescoping sleeves 22, 24 allow for up to three core jams to occur without interrupting the coring process.
  • the sleeves 22, 24 can be manufactured from a metal, plastic, or composite material.
  • the inner sleeve 22 and middle sleeve 24 are releasably coupled to the shoe assembly 18.
  • the shoe assembly 18 includes a lower shoe 26 that houses a core catcher 28 and an upper shoe 30 that is coupled to the tubular body 20 by thread 21.
  • the inner sleeve 22 has a first end 40 that can be releasably coupled to the upper shoe 30 by a frangible member 33.
  • the inner sleeve 22 also has a second end 42 that can be coupled to an end cap 44 that is slidably engaged with the tubular body 20.
  • the middle sleeve 24 has a first end 32 that is releasably coupled to the upper shoe 30 by a frangible member 34.
  • the middle sleeve 24 also has a second end 36 that has a stop member 38 that is coupled to the inner surface of the middle sleeve 24 and extends into the annulus 39 defined by the inner sleeve 22 and the middle sleeve 24.
  • slidably engaged means two components that are in contact or a close relationship that allows relative sliding movement between the two components.
  • Frangible members 33, 34 may be shear pins, screws, rivets, rings, or a combination thereof that are selected to break and release the sleeve from the shoe assembly once a preselected shearing force is applied to the frangible members.
  • the sleeves 22, 24 may be releasably coupled to the shoe assembly 18 by other releasable members or mechanisms, such as a latch or collet that are configured to release once a predetermined force is applied.

  • the middle sleeve 24 is slidably engaged with the tubular body 20 via one or more stabilizers 35 that are coupled to the outer surface of the middle sleeve 24.
  • the stabilizers 35 act to maintain the middle sleeve 24 in a position substantially aligned with the centerline of the tubular body 20 and the coring bit 16.
  • the stabilizers 35 can also reduce sliding friction between the middle sleeve 24 and the tubular body 20 and prevent the middle sleeve 24 from becoming stuck within the tubular body 20.
  • the stabilizers 35 can be constructed from metal, plastic, or a composite material.
  • the inner sleeve 22 is slidably engaged with the tubular body 20 via the end cap 44 and stop member 46.
  • the stop member 46 extends outward from the inner sleeve 46 into the annulus defined by the inner sleeve 22 and the middle sleeve 24.
  • the stop member 46 is disposed at a location proximate to the first end 40 of the inner sleeve 22 and is slidably engaged with the middle sleeve 24.
  • the likelihood of core jamming can also be reduced by the first end 40 of the inner sleeve 22 being disposed proximate to the core catcher 28 so that substantially the entire inner surface of the core catcher 28 is initially covered by the inner sleeve 22.
  • the leading edge of the core has to pass from the interior of the coring bit 16 into the inner sleeve 22.
  • Disposing the first end 40 of inner sleeve 22 as close as possible to coring bit 16 reduces the likelihood that the core can become jammed in the core catcher 26 before entering the inner sleeve 22.
  • the inner barrel assembly 10 is shown receiving a core 50.
  • Coring bit 16 and outer barrel 14 (not shown) are rotated and advanced through a formation to form core 50.
  • the leading edge 52 of the core 50 is received in the inner sleeve 22.
  • the leading edge 52 of the core 50 moves farther into the inner sleeve 22 until the leading edge 52 reaches the top cap 44 or the core 50 becomes jammed in the inner sleeve 22.
  • the inner sleeve 22 is shown in a position released from the shoe assembly 18. Continued drilling with coring bit 14 will move the inner sleeve 22 relative to the middle sleeve 24. Once the lower end 40 of the inner sleeve 22 passes the lower end 32 of the middle sleeve 24, the middle sleeve 24 will be exposed to the core 52. As drilling continues, the core 52 moves the inner sleeve 22 relative to the middle sleeve 24 until the core becomes jammed in the middle sleeve 24 or until the stop member 46 on the inner sleeve 22 contacts the stop member 38 on the middle sleeve 24.
  • the inner sleeve 22 and middle sleeve 24 are shown in a position released from the shoe assembly 18.
  • the core 52 moves the inner sleeve 22 and middle sleeve 24 until the inner sleeve 22 reaches the top end of the tubular body 20 or the core 52 jams in the tubular body 20.
  • the coring assembly 10 can then be removed from the formation 50.
