Definitions

  • a number of devices may be used to make up drill pipe sections including power tongs and mechanical roughnecks. Power tongs are more commonly used in making up casing strings or tubular sections, and in some cases do not posses sufficient strength to make up drill pipe.
  • the spatial arrangement of the rollers may be fixed or may be movable to accommodate different diameters of drill pipe.
  • Figure 1 is perspective view of one example of the mechanical roughneck of the present invention
  • Figure 6 is a schematic diagram of one method of the present invention.
  • the present invention relates to a device and system for making up and breaking out sections of drill pipe. More specifically, the present invention relates to a spin wrench assembly and its arrangement of rollers. The rollers of present invention provide ease of removal and replacement. An example of a mechanical roughneck of the present invention is shown in
  • the mechanical roughneck 2 comprises a spin wrench assembly 4 connected to an upper end of a vertical frame 8 and a clamp assembly 6 connected at a lower end of the frame 8.
  • the clamp assembly 6 comprises a lower clamp 10 for grasping a box joint of the first drill pipe section (not shown), and an upper clamp 12 for rotatably grasping a pin joint of the second drill pipe section (not shown).
  • the clamp assembly 6 can be moved horizontally to position itself around the drill pipe sections.
  • the lower clamp 10 and upper clamp 12 define a first opening 30 in which the drill pipe sections fit.
  • Preferably jaws (not shown), attached to ends of the clamp cylinders 34 are movable to accommodate different drill pipe diameters.
  • the upper clamp 12 and lower clamp 10 are fixed in axial alignment, to ensure axial alignment and centering of the second drill pipe section as it engages or is broken out of the first drill pipe section.
  • the spin wrench assembly 4 comprises one or more roller assemblies 14 movably connected to a spin wrench support arm 22 and defining a second opening 32.
  • two roller assemblies connected to a single straight spin wrench support arm 22 are illustrated in the drawing, it would be well understood by a person skilled in the art that multiple roller assemblies may be arranged along a curved or angled spin wrench support arm 22 or along multiple spin wrench support arms 22 to define opening 32, without departing from the scope of the present invention.
  • the roller assemblies 14 are movable relative to one another along the spin wrench support arm 22 to thereby enlarge or reduce the size of the second opening 32. This allows the spin wrench assembly 4 to accommodate second drill pipe sections of varying diameter, while maintaining axial alignment between the second drill pipe and the first drill pipe sections.
  • Each roller assembly 14 comprises one or more rollers 16 rotatably supported on a support 18.
  • a support 18 is illustrated in the drawings in the form of a plate, although a number of different supports are possible including but not limited to platforms, frames and brackets.
  • the one or more rollers 16 are rotated by one or more roller motors 20.
  • one roller motor 20 is connected to each of the one or more rollers 16, however it would be understood to a person of skill in the art that the one or more rollers 16 could be driven by one motor 20 to drive them all.
  • a pulley or chain mechanism may be used to allow the one or more roller assemblies 14 to move together or apart to accommodate different sizes of drill pipe.
  • hydraulic valving 24 is used to function the mechanical roughneck.
  • operational power can be delivered electrically or pneumatically.
  • the hydraulic valving can provide energy for horizontal movement of the lower clamp 10 and the upper clamp 12 and horizontal movement of the spin wrench assembly 4.
  • the hydraulic valving 24 may also preferably operate rotation of the spin wrench roller motors 20 and rotation of the upper clamp 12 when the second drill pipe section is rotated into or out of the first drill pipe section. Movement of the mechanical roughneck can be controlled from a console 26 preferably mounted to the tool.
  • the console 26 may be a fixed, local device, or alternatively can be a remote wireless or hardwired console 26.
  • FIGS. 4 and 5 show a detail of the roller assemblies 14 and their components.
  • the support 18 is attached to the roller assembly 14 by a movable attachment means 28.
  • the attachment means 28 are preferably illustrated in the figures as a screw mechanism such as a jack screw, although it would be understood that other means including but not limited to bolts, clips or other movable attachment means would also work and are encompassed in the present invention.
  • the attachment means 28 more preferably comprises a screw fastened through a locking collar 46 into a bottom surface of the support 18.
  • the attachment means 28 can be loosened to lower the support 18, thereby allowing access to the rollers 16 for removal or replacement, as seen in the left hand side roller assembly 14.
  • the attachment means 28 can also be tightened to raise the support 18 back into a position for operation, as seen in the right hand side roller assembly 14.
  • one or more mounting bolts 36 can be preferably used to further secure the support 18 to the roller assembly 14 during drill pipe makeup or break out, as seen on the right hand side roller assembly 14. These bolts 36 are then removed prior to loosening of the attachment means 28, as seen in the left hand side roller assembly 14.
  • guide pins 42 can extend from a lower frame portion of the roller assembly 14. These guide pins 42 align with corresponding guide pin holes 44 in the support 18 to facilitate alignment of the support 18 with the roller assembly 14 during raising and lowering of the support 18.
  • the one or more rollers 16 are preferably rotatably mounted into the roller assembly 14 by means of a rotary drive mechanism having an external rotary connection 38 formed on the roller assembly and a corresponding internal rotary connection 40, formed on an inner end of the roller 16.
  • the rotary drive mechanism can be of any form known in the art including but not limited to splines, keys, hexagonal connections and square connections.
  • the rotary drive mechanism comprises an external spline formed on the roller assembly and a corresponding internal spline formed on an inner end of the roller 16, wherein both splines have toothed surfaces.
  • Figure 5 shows the external rotary connection 38 and internal rotary connection 40 at an upper end of the rollers 16, it is also possible that these features are instead present at a lower end of the rollers 16.
  • the lower end of the rollers 16 may comprise a shaft (not shown) that fits into a bushing or bearing (not shown) formed into to the support 18.
  • the toothed surfaces of the external rotary connection 38 and the internal rotary connection 40 have a chamfered end profiles to allow the toothed surfaces to rotate slightly as the chamfered ends meet and facilitate alignment of the toothed surfaces as the rollers 16 engage into the roller assembly 14.
  • rollers 16 of the spin wrench assembly 4 are operated by the roller motors 20 to rotate the second drill pipe section into the first pipe section or to break out the two drill pipe sections.
  • Such rollers 16 are well known in the art and can have metallic or elastomeric surfaces, with or without abrasive materials added to the surface material.
  • the rollers 16 are in constant frictional contact with the drill pipe section and will experience varying degrees of torque depending on pipe thread condition, size of threads, weight of pipe and other factors. In such conditions wear of the rollers' 16 surface or general breakage is not uncommon.
  • rollers 16 are first supported on support 18, which is movably attached to the roller assembly.
  • Loosening attachment means 28 lower the support 18 and allows access to the one or more rollers 16 supported thereon. Once lowered, the one or more rollers 16 can be removed individually as needed and replaced. There is no need to replace the entire roller assembly 14. Then, the attachment means 28 is tightened to raise the support 18 and one or more rollers 16 back into engagement with the spin wrench assembly 14.
  • mounting bolts 36 are removed before loosening the attachment means 28 and are re-fastened to the roller assembly 14 after tightening of the attachment means 28.
  • the support 18 is aligned with the roller assembly 14 by means of the guide pins 42 and guide pin holes 44 as it is raised.
  • the one are more rollers 16 rotatably engage the spin wrench assembly 14 by engaging external rotary connections 38 on the spin wrench assembly with internal rotary connection 40 on the one or more rollers 16.
  • the lowered support 18 supports the weight of the roller assembly 14 during removal.
  • roller assemblies can weigh around 50 pounds (about 23 kg), and typically require the use of a crane or winch line for support during maintenance operations.
  • the tools required for loosening the attachment means 28 and removing a roller 16 in the present invention are those typically carried by an operator during regular rig operations.
  • the present invention allows for the changeover of single rollers 16, in-situ without the need for secondary methods of supporting the weight of a roller assembly 14 such as a winch line or crane.
