6 FAQs about [Reverse Circulation Drilling Rig Video]
What is reverse circulation drilling?
A drilling method where drilling fluid and cuttings are brought to the surface through the inner tube of the drill pipe which is a hollow tube used to transmit drilling fluid and apply rotational force to the drill bit. 1.** Overview of Reverse Circulation Drilling:** RC drilling involves a dual-wall drill pipe system.
What cutting actions are used in the reverse circulation system?
The cutting actions used in the reverse circulation system include the rotary cut and the rotary crush actions. Shown here is in this video rotary cut. The unique direction of a water based flushing media is profiled.
What is a rotary cut rig?
These rigs are primarily associated with drilling large diameter wells in unconsolidated material ranging from 24 inches to 50 inches in diameter and up to 1000 feet deep. The cutting actions used in the reverse circulation system include the rotary cut and the rotary crush actions. Shown here is in this video rotary cut.
What is RC drilling & how does it work?
The other common RC method is air-assisted reverse. This method runs a fairly small air line inside the drill pipe to lift the cuttings. It is very successful because you do away with pump priming problems. It works very well in limestone (and similar) formations that produce water.
Why is RC drilling better than conventional drilling?
Reverse circulation (RC) drilling offers several advantages over conventional drilling, including lower operating costs and hassle. In RC drilling, cuttings are exhausted up the center of the bit and drill pipe, allowing for faster drilling (~2-8X faster than conventional drilling).
How does a RC rig work?
Unlike conventional drilling methods, the RC rig employs dual-wall drill rods: compressed air is injected between the outer and inner tubes, forcing the cuttings to travel back up through the center pipe to the surface.
