Abstract: A drill speeder. The drill speeder is used for increasing the rotating speed of a drill bit in drilling operation and comprises: an upper joint (1) connected to a drill tool (200) in the drilling operation; a lower joint connected to the drill bit (300); and three wing plates (9) arranged on the outer surface of a gear sleeve (10) of the drill speeder in an equal division mode, and closely attached to pistons embedded on the gear sleeve (10). When the drill bit (300) conducts a speed increasing operation, a drilling slurry column in the drill speeder jacks up the pistons (8) on the gear sleeve (10), and the wing plates (9) are opened and attached to the well wall. The drill speeder further comprises a sun shaft (12) and planetary gears (4).
