Abstract: A subsoil automatic rotary drilling system for drilling oil, mineral and water wells, characterized in that said system comprises, on a single system substructure, at least a triple-transmission hydraulic arrangement for lowering and raising a plurality of pipe elements to be introduced into and removed from a wellbore, said arrangement including a plurality of operating cables, each said cable having a dead end fixed to a cylinder carriage also supporting a plurality of transmission pulleys to handle together, while providing a triple stroke of pulling and pushing cylinders, two, three, four drilling pipe elements, having each a length of about 9.20 m (range 2).

Abstract: A movable well drilling rig for drilling either on-shore or off-shore new in-line arranged oil, gas, mineral and water wells or for servicing in-line non-productive wells with well heads emerging from ground by at least three meters where the rig has a drilling mast supporting a vertically upward and downward movable drilling rotary head, where the drilling mast is operatively associated at least a pipe and drilling bit and stabilizer container, pipe and drilling bit and stabilizer element gripping and loader devices as well as driving motors, and a control operator, cab and auxiliary servicing devices, wherein all the above components are operatively supported either on a ground movable substructure or on a floating platform.

Abstract: A monolithic well drilling rig for drilling either on-shore or off-shore new in-line arranged oil, gas, mineral and water wells or for servicing in-line not productive said wells with well heads emerging from ground by at least three meters, said rig including a drilling mast supporting a vertically upward and downward movable drilling rotary head, to said drilling mast being operatively associated a plurality of operating means including at least pipe and drilling bit and stabilizer container means, pipe gripping and loader means, drilling bit and stabilizer element gripping and loader means, motor driving means, a control operator cab and auxiliary servicing means, characterized in that said drilling mast/derrick and all said operating means associated with said drilling mast/derrick are operatively supported either on a ground movable substructure or on a water surface floating platform.
