Rotary Drilling Technologies (Air, Mud, and Dual Rotary)
Rotary technology uses a sharp, rotating drill bit and downward pressure to cut, or crush, through the subsurface. Impact energy is supplied to the drill bit from either an above ground or down hole impact hammer. This impact force aids in the drilling.
Rotary Drilling - An Overview - The Driller
2011年11月1日 · Rotary drilling uses a sharp, rotating drill bit to dig down through the Earth’s crust. Much like a common hand-held drill, the spinning of the drill bit allows for penetration of even the hardest rock. The idea of using a rotary drill bit is not new.

A rotary drilling rig, whether on land or offshore, can be thought of as a factory designed to produce only one product—an oilwell, or hole, as it is called in the business.
Rotary table (drilling rig) - Wikipedia
A rotary table is a mechanical device on a drilling rig that provides clockwise (as viewed from above) rotational force to the drill string to facilitate the process of drilling a borehole. Rotary speed is the number of times the rotary table makes one full revolution in one minute (rpm).
Rotary Drilling - an overview | ScienceDirect Topics
Rotary drilling is the most common methods of drilling, especially for exploratory and production wells. The depth reached by rotary drilling can be as much as five miles below the ground. In 2008, an oil well was drilled to 40,318 ft in Qatar.
Drilling rig is a device used to drill a hole, lower and cement casing in the well, and provide a means to perform various auxiliary functions such as logging, stimulation and well testing. Before the rig can be selected, the requirements of the subject must be determined.
