Definitions

  • the present invention relates to a substructure for a platform of a deep drilling device. More specifically, the present invention relates to sub-construction for a deep drilling platform, which includes an apparatus for making substantially vertical holes in geological layers e.g. contributes to the development of deposits.
  • the term “deposit” generally encompasses an occurrence of a substance in liquid, gaseous or solid form or energetically usable conditions in geological layers, in particular of oil, natural gas and geothermal energy.
  • drilling rigs drilling towers
  • drilling mast systems drilling mast systems
  • a drilling tool (the drilling head) is connected to a rotary drive arranged above the surface of the earth by a drill string and is set in rotation by this.
  • the drill string consists of standard rods screwed together and special units such as drill rods, non-magnetic rods, centering units, flushing motors, etc., which are used as required.
  • special units such as drill rods, non-magnetic rods, centering units, flushing motors, etc., which are used as required.
  • Standard rods are gradually joined together depending on the drilling progress.
  • the rotary movement is either generated or transmitted via driver rods (so-called Kelly rods) from a turntable or by a drill motor that can be moved vertically at the upper end of the drill string (so-called top drive).
  • driver rods so-called Kelly rods
  • top drive a drill motor that can be moved vertically at the upper end of the drill string
  • the entire drill string hangs on a suspension system consisting of a hook, cylinder pull, rope pulley and winch, so that the contact pressure on the drilling tool is due to the weight of the string and excess weight is absorbed by the suspension system.
  • Plants of this type are characterized by a drilling mast with a gable-like construction, inside which the drill string and the drill drive are located.
  • Drilling rigs of any of the aforementioned types can be mounted on platforms. These platforms are usually self-supporting. In the case of drilling rigs that remain in place for a long time, the drilling site can have a basement and the drilling platform can be arranged at ground level. In the case of shorter-term drilling sites or if a basement is not possible due to geological conditions or is undesirable for other reasons, the platform is placed on a substructure, which is usually built in the form of a welded steel structure at the drilling site.
  • the assembly and dismantling times of the drilling rigs are generally long because the platforms are manufactured on site.
  • Sheets delivered, handled, processed and processed as well to be assembled Extensive dismantling work and many transports are also necessary when changing construction sites.
  • the space required for assembly and disassembly is either very large or you need very large cranes. If a platform for a drilling site at sea (offshore drilling) is assembled in a shipyard, it must be brought to the destination in a complex campaign with tugs. Because of the high technical effort, the holes are expensive; this means that smaller deposits cannot be developed economically.
  • a substructure construction for a drilling rig which has a drilling platform carrying a drilling mast, is composed of a plurality of models. is constructed, whose external dimensions and suspension points match those of a standard sea container.
  • the modular design in the form of standard sea containers makes transportation and assembly much easier and cheaper.

  • the substructure preferably consists of one or more floors, each floor consisting of at least two of the modules and the platform being firmly connected to the modules of the top floor of the substructure.
  • At least two modules per floor are required to ensure that the substructure is stable.
  • the structure in such a way that at least two modules form a floor allows the total width of the floor to be adapted to the existing needs and conditions.
  • the height of the substructure can be varied by the number of floors.
  • each floor preferably consists of at least two rows of one or more modules arranged one behind the other, the modules of each floor being arranged in such a way that there is a continuous free space over the entire height of the substructure in which a drill string of the drilling rig runs.
  • each floor preferably consists of two rows of modules which are arranged next to one another with a space between the rows, the modules of the top floor being braced with one another by struts.
  • Each row can consist of one or more, preferably two, modules arranged one behind the other.
  • Two rows of one module per floor correspond to the minimum number for a secure stand of the substructure, provided that the modules are long enough to absorb tilting moments in the longitudinal direction, and thus result in the economic optimum for the construction of the substructure, unless other requirements require a larger number of modules require. If only modules with the dimensions of short standard sea containers are available, two modules per row should be used. If these modules are also arranged in the longitudinal direction with a gap, the total footprint can be increased. The largest footprint is achieved when the four modules on each floor are distributed over the corners of the drilling platform.
  • a guide frame of a handling device for segments of a drill string and other loads is provided in the recess and a recess, if any, is clad on the opposite side, furthermore the guide frame is modular so that the height of an element of the mast corresponds to the height of the module to which it is attached.

  • the substructure can be used in the offshore area.
  • the erection time of an oil rig can be shortened by parallelizing the manufacturing processes of the basic structure on the one hand and the modules of the substructure on the other. This means that raw material deposits can be used more quickly and the return flow of funds invested in the exploration can be accelerated. Overall, this increases the economic viability of an exploration project.

  • Platform 3 can be expanded for additional units such as degasser, compressors etc.
  • the substructure 4 or its modules 41 can perform a variety of tasks in addition to the pure support function at the drilling site. As already mentioned, tanks and material stores as well as stairways can be accommodated here. In addition, these modules can also serve as transport containers for them, i.e. All tanks, storage facilities and stairwells can be pre-installed and are ready for use at the drilling site, without having to first select and set up a parking space or intermediate storage space, and without additional installation work. Finally, free space within the modules can be used as additional transport space for other facilities required at the drilling site.
  • This modular substructure 4 makes it possible to work with the drilling system even without a basement, since the blow-out preventers 88 can be accommodated at ground level between the modules. At the same time, this enables use for workover work on existing boreholes with mostly ground level preventers.
  • the present invention is not limited to drilling equipment on the ground, but can also be applied to an offshore drilling rig (not shown in detail).
  • Offshore drilling rigs are usually assembled in a shipyard and then brought to the drilling site by tugs and anchored there. Following the inventive concept of the present invention, it is also possible just assemble a floating floor with the most necessary equipment in a shipyard, bring it to the drilling site with tugs and anchor it there. In the meantime, modules can be manufactured and equipped at another location, which together form the individual floors of the oil rig.
  • the individual floors will be made up of a large number of modules arranged one behind the other and next to one another.

  • the modules can then be brought to the anchored floating floor in a container ship and assembled on site.
  • the resulting time saving can be increased if the towing time is used for assembly.
  • the floating floor of two container ships can be taken in the middle alongside and brought to and from the drilling site as a unit. This means that the entire towing time can be used to assemble the modules, except in the event of rough seas or weather.
