Rotary Drilling Rig

Rotary Drilling Rig

Rotary drilling rig is used for drilling rock formations with rock hardness coefficient f≤6 in open pit mines, and can also drill hard interlayer rocks with f=7-11. When drilling, the rotary torque and axial pressure are applied to make the drill bit rotate and feed to cut the rock.

Maximum output torque(KN.m):
45-150

Maximum drilling diameter (mm):
1000-2000

Rotary drilling rig is a powerful machine used in the oil, gas, and mining industries. You can use it for boring deep holes into the earth’s subsurface. Different from the conventional cable tool rigs, the rotary rig utilizes a rotating drill bit attached to a drill string to cut through rock formations.

The system is powered by a rotary table or a top drive mechanism. It provides torque to the drill bit while circulating drilling fluid or mud to cool, lubricate, and remove cuttings. These rigs are highly efficient for deep well drilling. And you can also use it in onshore and offshore operations.

With advanced automation and real-time monitoring, modern rotary rigs enhance the drilling accuracy, speed, and safety. These make them indispensable in energy exploration and geotechnical engineering.

Key components and working principle of the rotary drilling rig

The rotary drilling rigs are consisted of several critical components. They include the mast, drawworks, drill string, rotary table or top drive, mud pumps, and blowout preventers.

The drill bit is attached to the bottom of the drill pipe. When it rotates, it can break the rock formations. And the drilling fluid is pumped down the pipe and back up the annulus. Meanwhile, it carries debris to the surface.

The rotary table or top drive provides rotational force. The drawworks controls the hoisting and lowering of the drill string.

Advanced rigs are featured with automated pipe handling system and real-time data monitoring to optimize drilling parameters. For example, the weight on bit, rotation speed, and the mud flow rate will be monitored. This ensures efficient penetration rates and minimizes equipment wear.

Applications and advantages of the rotary drilling rigs

Rotary drilling rig is widely used in oil and gas exploration, water well drilling, geothermal energy extraction, and mineral exploration.

The ability to drill thousands of meters deep makes them ideal for unconventional resources. For your shale gas and deep-sea oil reserves projects, you can use this machine for drilling. Compared with other drilling methods, the rotary rigs offer faster penetration rates. And it has greater depth capacity, and also improves the wellbore stability because of the continuous mud circulation.

Except for these, Daswell modern rigs incorporate eco-friendly technologies, including the closed-loop mud systems and reduced emissions. They are aligning with sustainable drilling practices.
