Functions of a Rotary Table on a Drilling Rig

A rotary table is essential on a drilling rig. It transmits rotational force, drives the drill bit, supports the drill string, and facilitates drilling fluid circulation.

Transmit Rotational Force

The rotary table converts engine power into rotational force, which is then transferred to the drill string. Efficient force transmission is crucial for effective and speedy drilling.

Drive the Drill Bit

The rotary table's rotational force drives the drill bit, cutting through rock to create a borehole. Continuous rotation ensures steady drilling, allowing the bit to penetrate various geological formations.

Support the Drill String

The rotary table provides a stable platform for smooth drill string rotation. It handles substantial weight and dynamic forces, preventing wobbling or misalignment that could affect drilling accuracy and safety.
