Title:
NOVEL POLAR DRILLING RIG
Document Type and Number:
WIPO Patent Application WO/2021/232993
Kind Code:
A1
Abstract:
A novel polar drilling rig, comprising a main engine (1), which has a K-type derrick (11) and a box-on-box substructure (12); the main engine (1) is placed on a translation apparatus (2), the translating apparatus (2) is provided with multiple zones in the horizontal and vertical directions, supporting devices are placed in the multiple zones, and the supporting devices comprise a solid control system (3), an electric control chamber (4), a power unit (5), a catwalk drill rod rack platform (6), a reserve tank and material chamber (7), a heating apparatus (8) and a generator unit (9). The K-type derrick (11) has a simple and compact structure, is light-weight, and is capable of forming a smaller main engine heat preservation space to save on transport costs; the supporting devices use a two-layer stacked layout extending into the space, which reduces the heat preservation area space and the required well site area, thereby greatly reducing polar drilling costs; and the drilling rig is configured to have the multilayer-structured catwalk drill rod rack platform so that drilling tools and well control devices are centralized and built-in, so that when the drilling rig is translated, all of the drilling tools can be translated along with the drilling rig, thereby improving the efficiency of moving the drilling rig.
