Abstract
A system for drilling a wellbore includes a drill string, bottom hole apparatus, and a rotation regulator. The rotation regulator includes a compound planetary gear set with a first and second planetary unit. The first planetary unit is disposed in a proximal region of the rotation regulator from the drill string. The second planetary unit is disposed in a distal region of the rotation regulator from the drill string. The gear set includes a hollow central shaft. The central shaft is common between the first and second planetary units. The central shaft is of a different outer diameter at each planetary unit. A bearing is arranged between the first and second planetary units. The drill string, rotation regulator, and bottom hole apparatus are connected in series, so the rotation regulator mechanically transmits the rotation of the drill string into the bottom hole apparatus.
