Definitions

  • the present invention relates to an integrated method and apparatus for loading, interconnecting and disconnecting, and storing tubulars on an oil drilling platform without interrupting the drilling process.
  • the drilling operation when the drill bit has penetrated such a distance into a borehole that only a small part of the drill string extends upwards from the upper surface of the drill floor, the drilling operation must be stopped, and a new tubular drill string section moved from a storage site or rack positioned outside the drill floor and connected to the upper end of the drill string. Once the new section is connected the drilling operation may be continued.
  • the length of the drill string sections is 30 feet or about 10 m. This means that each time the drill bit has penetrated further 10 m into the underground the drilling operation has to be stopped and a further drill string section has to be added as described above.
  • One solution commonly used to reduce the idle time on drilling rigs is to assemble two drill string sections, or singles, each having a length of about 10 m into a 20 m stand, or double, placing the singles in a mousehole adjacent to the drilling opening and connecting the singles by using air tuggers and spinning wrenches while the drilling operation proceeds.
  • One exemplary system and apparatus for such offline standbuilding is described in U.S. Patent No. 4,850,439 .
  • these conventional offline standbuilding systems do create significant efficiencies in the drilling process, they generally utilize many complex pieces of equipment, such as, hoists and multi-purpose pipehandling machines that result in a system which is complicated, costly, and requires significant ongoing maintenance.
  • a system having the precharacterising features of Claim 1 is known from US-A-4610315 .
  • the present invention provides a method and apparatus for moving pipe on a rig floor between a number of different stations including an off-floor rack, a preparation opening, a borehole, and a storage area, such that tubulars can be loaded onto the drill floor, prepared at the preparation opening, loaded onto or off of the storage rack, and connected to the drill string while drilling is simultaneously conducted at the borehole.
  • the method and apparatus comprises at least two pipehandling devices for communicating pipe between a storage area off the drill floor, a storage area on the drill floor, at least one preparation opening, and a drill opening.
  • one of the at least two pipehandling devices is a tubular load and preparation pipehandling device designed to move joints of drill pipe or other tubulars from the V-door of the rig and deliver them into a pair of preparation openings for building stands while drilling activities continue at well center.

  • the invention comprises a method of loading, constructing and drilling comprising a series of steps including moving tubulars with the load and preparation pipehandling device from off the drill floor to on the drill floor, then constructing stands of pipe out of the tubulars at the preparation opening, and then withdrawing the prepared stands from the preparation opening to the storage area by means of the storage pipehandling device.
  • the load and preparation pipehandling device picks up a tubular body at the V-door pick up point and moves it to a first preparation hole position.
  • the load and preparation pipehandling device is then moved back to the V-door pick up position and a second tubular body is hoisted and rotated to the preparation opening and placed in a second preparation opening.
  • the load and preparation pipehandling device is disconnected from the tubular body and the load and preparation pipehandling device rotated back to the V-door pick up position and a third joint is hoisted and slewed into position over the first preparation opening and joined with the first tubular using an iron roughneck or other conventional torque wrench device into a double.
  • the double is then hoisted clear of the first preparation opening and the load and preparation pipehandling device is slewed over the second preparation opening and the double is joined with the third tubular body to make a treble or stand.
  • the made-up length is then hoisted and the load and preparation pipehandling device is slewed towards the storage pipehandling device.
