None.
FIELD OF THE DISCLOSUREThe present disclosure relates generally to drilling rigs, and specifically to drilling rig structures for land drilling in the petroleum exploration and production industry.
BACKGROUND OF THE DISCLOSURELand-based drilling rigs may be configured to move from location to location to drill multiple wells within s a wellsite. It is often desirable to move the land-based drilling rig across an already drilled well within the wellsite for which there is a well-head in place. Further, mast placement on land-based drilling rigs may have an effect on drilling activity. For example, depending on mast placement on the drilling rig, an existing well head may interfere with the location of land-situated equipment such as, for example, existing well heads and may also interfere with raising and lowering of equipment needed for operations.
SUMMARYThe present disclosure provides for a land based drill rig. The land-based drilling rig includes a plurality of columns. Each of the columns is a polyhedron having a square base or is cylindrical. The land-based drilling rig further includes a drill rig floor coupled to the plurality of columns. The land-based drilling rig also includes a mast, the mast mechanically coupled to the drill rig floor.
The summary and the detailed description are further understood when read in conjunction with the appended drawings. For the purpose of illustrating the present disclosure, there are shown in the drawings exemplary embodiments of said disclosure; however, the disclosure is not limited to the specific methods, compositions, and devices disclosed. In addition, the drawings are not necessarily drawn to scale. In the drawings:
The present disclosure may be understood more readily by reference to the following detailed description, taken in connection with the accompanying figures, which form a part of this disclosure. It is to be understood that this disclosure is not limited to the specific devices, methods, applications, conditions or parameters described and/or shown herein, and that the terminology used herein is for the purpose of describing particular embodiments by way of example only and is not intended to be limiting of the present disclosure. Also, as used in the specification, including the appended claims, the singular forms “a,” “an,” and “the” include the plural, and reference to a particular numerical value includes at least that particular value, unless the context clearly dictates otherwise. The term “plurality,” as used herein, means more than one.
Choke house 80 may be positioned on or cantilevered to drill rig floor 30. In certain embodiments, choke house 80 may be positioned on choke house skid 82. Choke house 80 may include choke manifold 84. In certain embodiments, as shown in
Columns 40 may be polyhedrons having square base 42 and rectangular sides 44. In certain embodiments, the height of columns 40, as measured from square base 42 to drill rig floor 30 may be longer than the width of columns 40 as measured along square base 42. In other embodiments, the height and width of columns 40 may be the same. In other embodiments, columns 40 may be cylindrical. Columns 40 may be formed from structural supports, such as struts. While shown as having four columns 40, land-based drilling rig 10 may have any number of columns 40.
In the embodiments shown in the Figures, columns 40 may be positioned at or near edges 50 of drill rig floor 30, although such a position is non-limiting. In the embodiments shown in the Figures, as exemplified by
Mast 70 may be fixedly or pivotably coupled to drill rig floor 30. Mast 70 may include mast V-door side 72, which faces drilling rig V-door side 58. Mast V-door side 72 is an open side of mast 70. Equipment positioned within mast 70 may include travelling block 86 and top drive 74. Crown block 76 may be positioned on top of mast 70 and pipe rack 78 mechanically attached to mast 70.
In some embodiments, drill rig floor 30 may include one or more upper equipment support cantilevers 63. As depicted in
In some embodiments, as depicted in
A non-limiting embodiment of a hydraulic walker for use with drilling rig 10 is shown in
Once hydraulic walker 120 is in the extended position, sliding actuator 109 may be actuated to move walking foot 105 laterally relative to hydraulic lift assembly 107 from a first position to a second position as depicted in
One having ordinary skill in the art with the benefit of this disclosure will understand that the specific configurations depicted in the figures may be varied without deviating from the scope of this disclosure.
Those skilled in the art will appreciate that numerous changes and modifications can be made to the preferred embodiments of the present disclosure and that such changes and modifications can be made without departing from the spirit of said disclosure. It is, therefore, intended that the appended claims cover all such equivalent variations as fall within the true spirit and scope of said disclosure.
