Definitions

  • the present invention relates to a guided telescoping system for a snubbing or drilling assembly providing an integrated guiding and support structure.
  • Snubbing is the act of putting drillpipe or other rigid tubing into a wellbore when pressure is contained in the well. Snubbing is necessary when tubing, with or without one or more tools on it, needs to be run into a live well which is at high pressure.
  • the drillstring or tubing string is made up by connecting multiple threaded drillpipe or tubing joints together and snubbing them into the wellbore.
  • a typical snubbing assembly comprises a gin pole mast that is raised and lowered to pick up joints of tubing or drillpipe and position them for making up the drillstring; a work basket at the top of the snubbing assembly, supported on several work basket support beams that extend down to the rig floor; a rotary jackplate, travelling slips and rotary jackplate motor, a hydraulic assembly including hydraulic cylinders, guide tubes, a set of stationary slips near the rig floor, and a blowout preventer (BOP).
  • BOP blowout preventer
  • l A tong unit is typically also used with the snubbing unit, and is located in the work basket, either loose or mounted on a hinged arm that this clamped to a side of the work basket.
  • the tong In order to make up or break out a joint of tubing, the tong is manually moved and positioned around the tubing joint by an operator, then actuated to grip and torque the joint into or out of threading with a next joint.
  • the moving, positioning and operation of the tong is a common problem area in snubbing operations, leading to either injury of operators or poor positioning leading to damage to the tubing joint during a makeup or break out attempt.
  • the rotary jackplate and travelling slips are typically supported and moved by the hydraulic cylinders.
  • the hydraulic cylinders must also provide anti-rotation resistance and support to the assembly. Hydraulic cylinders are limited to certain load limits that determine how much a cylinder can be extended or retracted in operation, depending on the loads needed to be supported and moved by the cylinders. As a result of these additional rotational, torqueing and compressive forces on the hydraulic cylinders, hydraulic cylinders in snubbing units commonly reach their load limits far short of a full stroke length. Therefore multiple strokes are required to full snub a length of pipe into the well.
  • additional jackplate supports extending down to the rig floor are added to the assembly to prevent rotation of the jackplates and the snubbing assembly as the drillpipe is threaded and snubbed into the wellbore.
  • the jackplate guide tubes reduce potential cylinder damage while rotational force is applied to the cylinder rods, but require additional space and assembly time.
  • Snubbing assemblies are traditionally assembled in a number of stages and parts, due to the number of components involved. Firstly the rotary jackplate and motor are connected to one another and then lifted and bolted onto the hydraulic cylinders and/or jackplate guiding tubes. The jackplate structure is next lifted and bolted onto the workbasket, which has been previously affixed to its working basket support beams and to the gin pole mast. The tubing guide and hydraulic cylinders are affixed to the work basket as well.
  • Erecting snubbing assemblies is therefore time consuming and complex.
  • Transportation by truck requires at least two semi-trailers to carry all of the equipment to site and the number of steps needed for assembly requires multiple operators, adding cost and time to snubbing operations.
  • Multiple components and multiple assembly personal also increase risks to workplace safety.
  • US Patent Application 20120006565 teaches pipe guide apparatus for guiding a pipe during snubbing and includes a stationary pipe guide and a travelling pipe guide each define a pipe opening and has a flexibly resilient guide member having an opening with a diameter closely matching the outside diameter of the pipe being snubbed.
  • US Patent Application 20080053661 teaches a method of guiding tubing for hydraulic jacks that includes multiple guide plates attached to the hydraulic jack rods and a lateral support section to prevent buckling.
  • US Patent 8,333,238 teaches a snubbing unit where the support frame comprises a work platform. The support frame consists of top, bottom and side plates with an opening for the tubing and is connected directly to the blow out preventer.
  • US Patent 7, 1 17,948 teaches a snubbing unit for running and retrieving a string of tubing into a well under pressure selectively operates in a standalone mode and a rig assist mode. The unit has a lower frame for mounting during the stand alone mode on a snubber blowout preventer. Stationary weight supporting slips and snubbing slips are carried by the lower frame during the stand alone mode.
  • US Patent 5, 1 15,861 describes a method to support tubing during snubbing where there are upper and lower horizontal beams which vertical support legs between the beams.

  • the jackplate guiding unit 14 is serves a number of purposes including preventing the jackplate 12 from torqueing or buckling under the extreme forces during snubbing processes.
  • the work basket supports/jackplate supports 10 are telescopic to allow travel up and down of the work basket 8 relative to the jack plate 2, as seen in the differing position of the work basket 8 relative the jackplate 12 between Figures 7 and 9, for example.
  • the combination is a faster and more compact to rig-up. Furthermore, the compact design reduces the number of trucks needed to bring the equipment to the wellbore site, less personnel are required for assembly, and with fewer assembly steps, risks are reduced and the rigging process becomes safer.
  • the hydraulic cylinders 20 serve to raise and lower, the jackplate 12, with the travelling slips 18, as the drill pipe is fed into or raised out of the wellbore.
  • the drill pipe is snubbed inside the extendable tubing guide 16, which prevents buckling or bending of the joint of tubing or drillpipe as it is moved axially downwardly in snubbing.
  • the rotary jackplate 12, with travelling slips 18 and motor provide rotational movement and torque forces during drill string snubbing.
  • the jackplate guiding unit 14 and particularly the unitary work basket supports/jackplate supports 10 reduce torqueing strain on the hydraulic cylinders.
  • the work basket supports/jackplate supports 10 also support axial loads of the jackplate 12 as it carries tubing sections and snubs them into the wellbore or pulls them out of a wellbore.
  • the support provided by the work basket supports 10 not only provides for stability to the jackplate 12 but it also allows for more sustained snubbing action, without needing to relieve rotational forces for fear of the assembly twisting. Since axial and rotational loads in the present invention are supported by the work basket supports 10, the hydraulic cylinders 20 are under reduced load and stress, and in particular, lessens torque stresses. This in turn allows the hydraulic cylinders 20 to extend and retract further before reaching their load limits.
  • the jackplate 12 with motor and travelling slips 18 is telescopically lowered on the unified jackplate guiding unit 14 to grip an upper end of a drill pipe or joint of tubing and raised to raise the string out of the ground, where it is broken out from the drill string or tubing string by rotation, picked up by the gin pole mast 4 and lowered to the rig floor.

  • the present work basket 8 is also laterally extendable to enlarge the working surface of the work basket and provide more floor space for operators.
  • the work basket 8 can be laterally reduced to meet load and sizing requirements for shipment via truck as part of the unified jackplate guiding unit 14, and can then be laterally extended once mounted at the wellbore. More preferably, the work basket 8 is extended by hydraulic means.
  • the present work basket is built with a lower riser for housing and holding the jackplate when the hydraulic cylinders are extended.
  • This lower riser ensure that the jackplate, travelling slips and auxiliary equipment are positioned at such a height that an operator can easily reach to makeup or breakout the tubing sections, without the need to work at a height above the operator's head.
  • a snubbing unit is presented that provides a single work basket support/jackplate support that is fixed, preferably in the form of a fixed riser 10A, and does not telescope.

  • the integrated tong 24 can be any standard tong well known in the art for makeup and breakout purposes and can particularly include any standard tongs known for use on snubbing rigs. Alternatively, the tong may be specially design to fit and operate on the riser 10A. Since the integrated tong 24 controls and manages all of the torqueing load for makeup and breakout operations, there is no need to especially design the fixed riser 10A to carry or handle any additional loads.

  • the work basket 8A is fixed to the fixed riser 10A and does not raise or lower. More preferably, the height of the fixed riser 10A is selected such that the work basket 8A, with the integrated tong 24 positioned just below it, are at a fixed height that is higher than the full extension of the jackplate 12A. This ensures that the workbasket 8A and tong 24 extending thereblow are always clear of the travelling jackplate 12A as it is raised and lowered for snubbing operations.
