  • the drilling rig can be set up with existing crane systems on platforms in a short time.
  • the individual elements can preferably be connected to one another without welding in order to also take into account the explosion protection on the drilling platform. Said positive or non-positive connection is to be preferred.
  • the mass limit is preferably 22 tons, more preferably 17 tons or 15 tons, and preferably 11 tons.
  • the drilling mast may be slidable on a frame in a first direction and the frame may be slidable on the drilling platform in a second direction that is substantially perpendicular to the first direction.
  • the drilling mast is displaceable on the frame in the first direction without hydraulic supply device and displaceable in the second direction together with the hydraulic supply device.
  • the hydraulic supply device may alternatively be located on opposite sides of the drilling mast with respect to the second direction.
  • Such a flexible arrangement allows short operating times of the drilling rig on the drilling platforms. In combination with the short setup and dismantling times, short-term assignments can be realized.
  • the substructure may have the height of at least 2, preferably 3 standard containers, whereby standard dimensions can also be implemented in the construction of the substructure.
  • the use of the drilling rig in an offshore drilling platform is of particular advantage, since the transport of individual elements to such a drilling platform is determined by weather conditions, the transport capacity of ships and the capacity of cranes either on the transport ships or on the drilling platform. Standard dimensions and the weight limit, which is preferably applied to a variety of individual elements, also allows the transport and loading and unloading of transport vessels in adverse weather conditions.
  • the functional elements for driving, supplying and operating a drilling rig and / or the periphery are at least partially redundant.
  • the drilling rig can still be operated even in the event of failure of individual elements and can be prevented from giving up the borehole due to the sticking, for example from the drill string.
  • Such an emergency operation does not have to be performed at full power, but the elements may be adapted such that the operation of a respective functional element allows a basic supply of the wellbore.
  • the control device for monitoring the drilling process can be designed to be redundant, so that monitoring of the drilling process is possible even in the event of failure of an operator or damage to a workplace.
  • a power supply device is preferably provided for a drilling rig, more preferably for an offshore drilling rig, in which an internal combustion engine and the generator are provided in two modules and the respective mass of the internal combustion engine of the generator has a mass limit value of below or equal to 25 tons, preferably does not exceed 11 tons.
  • the separation of internal combustion engine and generator makes it possible, for example, that generator outputs of, for example, at least 500 kVA can be implemented and yet a simple transport of the individual elements to offshore drilling platforms is possible.
  • the modules can be connected to one another in a gastight manner, which takes account of explosion protection.
  • another module in which a heat exchanger and a fuel tank are provided, may be provided at the power supply device, and an even further module may be provided with the input lock and the control panel.
  • these modules can also be integrated into the module of the internal combustion engine and / or the generator.
  • Such a modular subdivision allows strict compliance with a mass limit and full high performance performance on drilling rigs, preferably offshore rigs.

Abstract

L'invention concerne une installation de forage conçue pour être montée sur une plate-forme de forage et comportant un mât de forage pourvu d'un chariot d'avance et présentant au moins deux segments, le mât de forage pouvant être érigé de telle façon qu'au moins un segment est élevé au moyen du chariot d'avance. L'invention concerne également un procédé de montage de mât de forage présentant au moins deux segments, qui consiste en les étapes suivantes: fixation d'un chariot d'avance; positionnement d'un segment de mât au-dessous du chariot d'avance; soulèvement dudit segment par le chariot d'avance. Ceci permet d'éliminer le recours à des dispositifs auxiliaires supplémentaires pour l'érection du mât de forage et de gagner de la place.
