Definitions

  • the disclosure relates to a substructure for a mobile drilling rig.
  • a substructure for a mobile drilling rig.
  • a substructure while a working platform with the drilling mast supporting construction is understood.
  • individual units or modules of such a substructure are sometimes referred to as a substructure or individually for distinction sometimes as a sub-module.
  • the disclosure thus also relates to such substructure modules and subsequently to a method for assembling and dismantling such substructures and substructure modules and their use for erecting a mobile land rig and finally a mobile land rig with at least one such substructure or substructure modules.
  • Substructures for mobile drilling rigs are known per se. Frequently, one or more containers are used as submodules. Such substructure modules are placed individually or in the form of two or three stacked containers ("box-on-box" system) in pairs next to each other and act as a kind of supporting structure for a built thereon and designated in technical terminology as Rigfloor working platform of the rig which raises the boom. Between the sub-modules of the drill string is drilled and between the sub-modules and the platform remains room for a so-called blow-out preventer.
  • containers as substructure modules has the advantage that conventional components are usable and that the interior the container is usable for receiving aggregates of the drilling rig.
  • Mobile land-boring machines are types that can be transported and set up in a fortnight, depending on the environment. If no restrictions with regard to transport widths and transport heights are to be observed, for example in the desert, preassembled assemblies can reduce the construction time to approx. Seven days. Special plant types should be operational within a period of a few hours to three days, depending on the size of the plant.
  • substructure modules have been constructed which have, for example, pivotable supports or a scissor lift mechanism between a lower and an upper base part.
  • Substructure modules with swiveling supports or a scissor lift mechanism have the advantage that their height can be reduced for transport purposes. Two or more sub-modules may then be transported one upon the other on a heavy-duty trailer or the like. This reduces the number of transport operations required, thus reducing the overall duration of the transport of the rig and all components and aggregates thereof.
  • the lower and upper base part are designed as steel profiles and the lower base part transmits the forces in the ground, in particular in a foundation, while the upper base part acts as a support for another sub-module or for the working platform.
  • the lower and the upper base part of a sub-module for a mobile drilling rig are sometimes referred to as a lower part or upper part of the sub-module and the sub-module itself as a box.
  • US 2007/0240909 A shows a sub-module for a mobile land-based drilling rig with a lower and an upper base part and with two side hinged supports between the two base parts, wherein the supports have a joint in the middle and wherein the two supports at their ends hinged to the lower and the upper Base part are connected.

  • a center joint in relation to the longitudinal extent of the support allows regular loading conditions and compared to exactly one up or down from the center between the end points of the support arranged joint a parallel end position of both adjoining the joint support segments in the folded state. This leads to a minimization of the height of the sub-module in the collapsed state.
  • the joint which enables the foldability of the support is referred to as an inner joint with regard to its position along the longitudinal extent of an unfolded support.
  • a first, inner stop point for lifting harness and / or at the end of an outwardly facing lever has a second, outer stop point for lifting harness
  • the first stop position can also be formed directly on the upper base part.
  • the two stop points for lifting equipment - hereinafter also sometimes referred to as inner or outer lifting points - allow an automatic setting up and folding the hinged supports and thus an automatic construction and dismantling of the substructure module itself.
  • a single such attack point allows at least one automatic installation or Folding the hinged supports and substructure.
  • the sub-module each side has two similar folding supports and that each hinged support has these lifting points. If the inner lifting points are used on both lateral supports to build the sub-module with, for example, a crane, using these inner lifting points, the upper base part can be lifted and, due to the weight of the lower base part, unfolding of the lateral supports.
  • a stable or stabilizable configuration of the hinged support will result, particularly if, in supports with an off-center hinge (see below), the two are opposite one another at the hinge or hinges Face surfaces of the support segments come into contact, and the sub-module can be discontinued at the site.
  • the configuration is self-locking, especially for supports with an off-center hinge, and the weight ensures the position / configuration of the unfolded side supports.
  • a fixing of the unfolded lateral supports If the sub-module is to be dismantled, the outer lifting points are used.
  • the lever at the free end of each of which is located one of the outer lifting points, causes when the sub-module is raised at the outer lifting points with, for example, a crane that the outer lifting points having upper support segments are pivoted.
  • the upper base part is lowered thereafter, a collapse of the lateral hinged supports results.
  • the upper base part can then be further lowered until it comes either to lie on individual sections of the folded-up supports or the lower base part.
  • the sub-module may be fixed, for example, by inserting bolts into the eyes of tabs formed or molded onto the lower and upper base members.
  • the entire sub-module possibly with individual or more therein aggregates of the drilling rig or the like, be raised again with, for example, a crane and the collapsed configuration is maintained.
  • the collapsed sub-module can be stored on a means of transport, for example a heavy-duty trailer. This caused by the lifting of the substructure module at outer lifting points pivoting of the upper support segments also results in columns with an eccentrically arranged inner joint.

  • the upper base part can be lowered and it results in the described folding the side hinged supports.
  • the upper base part can then be further lowered until it comes either to lie on individual sections of the folded-up supports or the lower base part.
  • the collapsed configuration already described above is achieved and the above applies accordingly.
  • the advantage of such a sub-module - such a box - is that this or this can be easily erected, because it is sufficient to raise its or its upper part until the or each side support folds out and so a height of the sub-module in one Determines operating configuration.

  • an inner joint or the inner joint of the or each foldable support is outside a line (force line) extending in the unfolded state through the center of gravity of each column segment and allows contact of the individual support members to each other. Consequently, vertical force components are directed from the upper base part and the support segment acting above the inner joint directly into the support segment engaging below the inner joint and from there into the lower base part.
