Definitions

  • the invention relates to a drilling rig for creating deep holes for the onshore area with at least one drilling device, wherein the drilling rig is designed movable with respect to the terrain surface.
  • Deep wells have been produced for decades for exploration of oil and natural gas deposits to depths of over 5,000 meters.
  • the current drilling operation has not insignificant effects on the environment through sound, dirt and construction site operation in general (emission control), especially on flora and fauna.
  • deposits to be explored are often located in areas of particular sensitivity or nature to be protected, especially emission-sensitive fauna, etc. Due to the above-mentioned effects, it is often difficult to drill a deep hole in such areas.
  • Deposits are to be understood as meaning, in particular, deposits of hydrocarbons, gases, storage reservoirs for gases, liquids or other liquid products, gases or wastes of any kind to be disposed in pores and / or fractures. Especially in sensitive areas is added that such a necessary for a hole drilling site brings a not inconsiderable land consumption.
  • deposits that can be economically exploited only under certain conditions. For example, it may be necessary to drill many wells into the deposits at short intervals, either to ensure the highest possible extraction, or to physically affect the reservoir through the many wells. This may in particular be oil sands or oil shale.
  • the invention has for its object to provide a drilling rig to be able to be drilled with a variety of holes as deep wells at short intervals with little set-up times.
  • the invention has the object to be able to use such a system in remote areas.
  • the system can also be used under extreme climatic conditions. Since in such areas usually also special ecological conditions prevail, it is further advantageous if the ecological impairment of the Environment as low as possible, especially in terms of land consumption.
  • This object is achieved in that the necessary auxiliary equipment for drilling are arranged substantially within the drilling rig and that the position of the drilling device is movable within the drilling rig with respect to the drilling rig.
  • the area consumption can be kept low because no large hole is required.
  • the drilling rig is a kind of three-dimensional well site that carries all of its necessary elements with it. At the same time the plant becomes self-sufficient and can be used in remote areas. The driveability of the system allows the individual drilling points to be approached, and because the essential elements are already present on the drilling rig, a large part of the set-up time between the drilling points is eliminated.
  • the drilling device that is to say the derrick with the associated elements, can additionally be moved within the drilling rig, a certain number of bores can be brought into close proximity without displacing the drilling rig, which in turn reduces set-up times.
  • An advantageous teaching of the invention provides that at least two drilling devices are provided. By providing two drilling devices, both preferred with respect to the drilling rig can be moved separately, the speed of drilling is greatly increased in tight Bohrrastern.
  • a further advantageous teaching of the invention provides that the drilling rig is surrounded by a casing which completely shields the drilling rig against environmental influences.
  • the sheath is advantageously thermally insulating and possibly sound-insulating. In this way, the teams and the technology are easily protected against extreme conditions. At the same time a temperature control and ventilation are possible. The environmental impacts are low.
  • the sheath is provided with closable openings. These openings allow the drill rig to completely nest in, but still allow for adequate and easy supply of the drilling rig with supplies of material, etc.
  • a further advantageous teaching of the invention provides that the auxiliary units are arranged exchangeable modular. This allows all technical areas of the rig to be serviced and repaired be exchanged quickly. In this simple way, the downtime of the system is further reduced and the repair area can be provided off-site. Also, the transport in remote areas is simplified. It is advantageous if the modularity is achieved by arranging the respective auxiliary units in containers, preferably standard container, because thereby the transportability by truck possibly also by helicopter is improved and thereby the supply availability of the drilling rig in remote areas.
  • a further advantageous teaching of the invention provides that the auxiliary assembly modules can be inserted through the openings of the casing and / or exchangeable. It is particularly advantageous if the openings and the associated door sizes are adapted directly to the slot of the module in the drilling rig. As a result, the modules can be changed quickly and minimize the climatic adverse effects on the drilling rig during the Wechseins. The speed of change is further increased when quick connectors are provided
  • the drilling rig is provided with a chassis, which is preferably off-road, and particularly preferably consists of individual track suspensions. These are good off-road especially on bad surfaces. Furthermore, with them on the dimensioning in terms of length and width, the load-bearing capacity made possible by the respective soil can be achieved.
  • a further advantageous teaching of the invention provides that a crane module is arranged above the drilling device.
  • a further advantageous teaching of the invention provides that the drilling device and / or auxiliary drilling devices are arranged on at least one movable base, particularly preferably a carriage, which is movable relative to the drilling rig. This represents one easy way to achieve the mobility of the drilling device. Furthermore, it is advantageous that a preventer of the drilling device and / or the hydraulic supply of the borehole (choke manifold) are arranged on at least one movable base, particularly preferably a carriage, which is movable relative to the drilling rig. It is particularly advantageous if the base elements are moved synchronously.
  • a further advantageous teaching of the invention provides that a helicopter landing gear is provided on top of the drilling rig.
  • a helicopter landing gear is provided on top of the drilling rig.
  • the use of coil tubing is conceivable.
