Automatized drilling rig at high efficiency and security for drilling wells for hydrocarbon extraction

摘要

Drilling rig (1), comprising rig floor (12) raised off the ground; mast (2), rig floor (12), drilling head (25); mud circulation circuit (3) comprising main circuit (31) (fig 5A) and secondary circuit (32) (fig 5A), recovery circuit for the mud (33) (fig 5A) and collector circuit (34) (fig 5A); automated connection clamp (4) connecting the secondary circuit (32) to a drilling rod (14), comprising radial aperture (142), comprising movement arm (41) (fig 3C), a central body (42) (fig 3C), gripping system (44) (fig 3C); first manipulator (5), capable of assembling at least two drilling rods (14) together, comprising linear movement device (52) (fig 6); a locking tong (54) (fig 6) capable of generating torque over these rods to ensure locking, and lifting device (56) (fig 6B). Said mast (2) is telescopic, comprising a movement system (22) (fig 1C) in turn comprising a supply chamber (226) (fig 2A) and two hydraulic pistons (222,224) (fig 2A) aligned in a single direction, parallel to the vertical axis (Z), and acting in opposite senses to each other. A method of assembling drill rods, using the manipulator to hold, align, screw and lock together a series of drill rods.
