HIGH EFFICIENCY AND HIGH SAFETY AUTOMATED DRILLING RIG FOR SINKING WELLS FOR EXTRACTING HYDROCARBONS

摘要

Drilling rig (1) for creating wells for extracting hydrocarbons, comprising a rig floor (12) raised off the ground; a mast (2), located on the rig floor (12), along which slides a drilling head (25); a mud circulation circuit (3) for circulating drilling mud (M), comprising a main circuit (31) and a secondary circuit (32) for introducing mud, a recovery circuit for the mud (33) and a collector circuit (34); an automated connection clamp (4) for connecting the secondary circuit (32) to a drilling rod (14), comprising a radial aperture (142) for continuously circulating the mud, comprising a movement arm (41), a central body (42), a gripping system (44); a first manipulator (5), capable of assembling at least two drilling rods (14) together, comprising a linear movement device (52); a locking tong (54) capable of generating a torque over these rods to ensure that they are locked, and a lifting device (56). Said mast (2) is telescopic, comprising a movement system (22) in turn comprising a supply chamber (226) and two hydraulic pistons (222,224) aligned in a single direction, parallel to the vertical axis (Z), and acting in opposite senses to each other.
