<p>Well drilling apparatus (2) and method associated therewith, which is able to shift from a first assembly operating configuration to a second use operating configuration and vice versa. Said apparatus (2) comprises a sub-structure (21), which supports said apparatus (2), a mast (23), which is pivoted to said sub-structure (21), around which it rotates so as to shift from said assembly operating configuration, which is substantially horizontal, to said use operating configuration and vice versa; a drill floor (22), which is able to be lifted and is connected to the mast (23); an actuating device (3), which is adapted to allow the drilling apparatus (2) to shift between said two operating configurations. The actuating device (3) is a hydraulic device, which is directly connected to the mast (23). The drill floor (22) comprises a first portion (22a), projects with respect to said mast (23), and a second portion (22b), which is constrained to said mast (23) and rotates with it. A draw-works (58) is installed, in a permanent manner, on the sub-structure (21).</p> |
