1. A modular transfigurable drilling rig system composed of multiple components, which system is transfigurable between a transport mode in which the components of the system are transportable and an operational mode in which the components are assembled to a drilling rig which is adapted to drill into a well center in the ground, the system comprising:
a base structure adapted to be positioned in the operational mode on the ground near a well center, which base structure comprises:
one or more base members;one or more drill floor members adapted to form a drill floor in the operational mode, said drilling floor in the operational mode being located at an elevated position above said one or more base members and the well center; andat least one bar-linkage mechanism comprising one or more beams that extend between a base member and a drill floor member, said one or more beams being pivotally connected to said base member and said drill floor member, which bar-linkage mechanism is operable to move between a transport position in which the drill floor member is in a lowered position relatively close to the base member, and a raised position in which the drill floor member is in its elevated position; a drilling rig mast which is movable between a substantially horizontal position and an operational position vertically above the well center, the drilling rig mast having a top end and a foot, foot; and at least one drive assembly to move the one or more drill floor members and the mast between the lowered and elevated position and the substantially horizontal position and the vertical operational position respectively, wherein at least one base member, at least one drill floor member, and an associated bar-linkage mechanism are integrated into a transportable base unit, which base unit is adapted to be placed on the ground to support the drilling rig thereon, and wherein the drilling mast is in its substantially horizontal position connectable to the drill floor member and/or to the bar-linkage mechanism of said transportable base unit when placed on the ground, and wherein said at least one drive assembly is integrated into the transportable base unit and engages on the bar-linkage member and/or the drill floor member thereof, said at least one drive assembly being embodied to move the drill floor member between the lowered and elevated position and simultaneously move the drilling mast—when connected to the floor member and/or the bar-linkage mechanism—between its substantially horizontal position and the vertical operating position thereof. |
