Problems solved by technology

[0027] Usually, the top drive and the mast are separated during the transport phase and are coupled to each other during the assembly phase or even in some cases where the mast is already in a vertical position, making the operation very complicated and requiring more time to perform operations aimed at installing the structure

Embodiment Construction

[0051] With reference to the above-mentioned figures, the drilling apparatus 2 is adapted to be transferred from a first assembled operating configuration to a second operating operating configuration, or vice versa. Said plant 2 comprises: a sub-structure 21 situated on the ground "S" and supporting said plant 2; a derrick 23 comprising a pivot point 23a and a fixed point 23a' and passing through said pivot point 23a is pivotally connected to said substructure 21, said mast 23 being rotated about said pivot point 23a so as to transition from said assembly working configuration which is generally horizontal to said vertical working configuration, or in turn.

[0052] The apparatus further comprises: a drilling floor 22, which can be raised and connected to the mast; and actuating means 3, adapted to enable the drilling apparatus to be transferred from the assembled configuration to the use configuration. The actuating means 3 are hydraulic means connected directly to the mast...

Abstract

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).

Description

technical field [0001] The invention relates to a movable drilling equipment or land drilling rig, and relates to a related assembly method. [0002] In particular, the present invention relates to a drilling rig for the search and extraction of fossil fuels such as oil or fuel gas. [0003] The drilling rig is in an assembled working configuration at ground level in which it is fully assembled in a horizontal position and is in use for drilling a well when it is raised in a vertical position construction, all in a single operation. [0004] Furthermore, the equipment according to the invention is modular and can be easily assembled and disassembled, thereby enabling the equipment to be moved from one drilling site to the next in a rapid manner, thus reducing disassembly and reassembly the amount of time it takes. Background technique [0005] Protruding derricks, which are included in the drilling rig or structure, are widely used in surface drilling operations. [0006...
