WELL DRILLING APPARATUS AND ASSEMBLING AND DISASSEMBLING METHOD

摘要

A well drilling apparatus (2) and method associated therewith is able to shift between a first assembly operating configuration and a second use operating configuration. The apparatus (2) includes a sub-structure (21), which supports the apparatus (2), a mast (23), which is pivoted to the sub-structure (21), around which it rotates to shift between the assembly operating configuration, which is substantially horizontal, and the use operating configuration. A drill floor (22) is liftable and connected to the mast (23). An actuating device (3) allows the drilling apparatus (2) to shift between the two operating configurations. The actuating device (3) is hydraulic and directly connected to the mast (23). The drill floor (22) includes a first portion (22a), projects with respect to the mast (23), and a second portion (22b) constrained to and rotating with the mast (23. A draw-works (58) is permanently installed on the sub-structure (21).
